Introduction

With the global energy crisis and environmental problems becoming increasingly severe, building energy conservation has become the focus of attention of governments and society in various countries. As a key factor in improving building energy efficiency, building insulation materials have attracted much attention. As a new additive, DMAEE dimethylaminoethoxy has gradually emerged its application potential in building insulation materials. This paper aims to explore the application effect of DMAEE in building insulation materials, analyze its enhancement effect on thermal insulation performance, and provide theoretical basis and practical guidance for the development of high-efficiency and energy-saving building insulation materials.

This study first introduces the basic properties and characteristics of DMAEE, and then analyzes in detail its application effect in common insulation materials such as polyurethane foam, polystyrene foam and glass wool. Through experimental research and data analysis, the influence of DMAEE on the thermal insulation properties, mechanical properties and durability of thermal insulation materials was evaluated. Later, the application prospects of DMAEE in building insulation materials were summarized and future research directions were proposed.

1. Basic properties and characteristics of DMAEE dimethylaminoethoxy

DMAEE (dimethylaminoethoxy) is an organic compound with unique molecular structure and chemical properties. Its molecular formula is C6H15NO2 and its molecular weight is 133.19 g/mol. DMAEE is a colorless and transparent liquid with a slight ammonia odor, easily soluble in water and most organic solvents. Its boiling point is 207℃, its flash point is 93℃, and its density is 0.943 g/cm³ (20℃).

DMAEE’s molecular structure contains two functional groups, amino and hydroxyl groups, which makes it excellent reactivity and versatility. The presence of amino groups makes them basic and can be used as a catalyst or neutralizing agent; the hydroxyl groups impart good hydrophilicity and reactivity, making it easy to react with other compounds. These characteristics give DMAEE a wide range of application potential in building insulation materials.

In building insulation materials, DMAEE is mainly used as an additive.Its mechanism of action is mainly reflected in the following aspects: First, DMAEE can improve the foaming process of insulation materials, improve the uniformity and stability of the cell structure, and thus enhance the insulation performance of the material. Secondly, DMAEE can react with other components in the insulation material to form stable chemical bonds, and improve the mechanical strength and durability of the material. In addition, DMAEE also has certain flame retardant properties, which can improve the fire safety of insulation materials.

2. Current status and development trends of building insulation materials

Building insulation materials are the key factors in improving building energy efficiency and reducing energy consumption. At present, common building insulation materials on the market mainly include polyurethane foam, polystyrene foam and glass wool. Polyurethane foam has excellent thermal insulation properties and mechanical strength, but is relatively expensive; polystyrene foam has low cost, but has poor fire resistance; glass wool has good thermal insulation and sound absorption properties, but is easy to absorb water and inconvenient to construct.

With the continuous improvement of building energy conservation requirements, traditional insulation materials face many challenges. First, the thermal insulation performance of existing materials is difficult to meet increasingly stringent energy-saving standards. Secondly, the durability and fire resistance of the material still need to be further improved. In addition, environmental protection and sustainability have also become important considerations in the development of insulation materials. These challenges have promoted the research and development and application of new insulation materials, among which the innovative use of additives has become an important way to improve material performance.

DMAEE, as a new additive, has provided new ideas for solving the above problems. By optimizing the addition amount and process parameters of DMAEE, the thermal insulation performance of the insulation material can be significantly improved while improving its mechanical properties and durability. In addition, the use of DMAEE can also reduce the production cost of materials, improve production efficiency, and provide technical support for the sustainable development of building insulation materials.

3. Analysis of the application effect of DMAEE in building insulation materials

In order to comprehensively evaluate the application effect of DMAEE in building insulation materials, we selected three common insulation materials: polyurethane foam, polystyrene foam and glass wool, and conducted experimental research on the addition of DMAEE. During the experiment, we strictly controlled the amount of DMAEE and process parameters to ensure the reliability and comparability of experimental results.

In the application experiment in polyurethane foam, we set up experimental groups (0%, 0.5%, 1%, 1.5%) with different DMAEE addition amounts. Experimental results show that with the increase of DMAEE addition, the thermal conductivity of polyurethane foam gradually decreases and the thermal insulation performance is significantly improved. When the amount of DMAEE added is 1%, the thermal conductivity of the material is reduced by about 15%, while the closed cell ratio of the foam is increased by 20%, and the mechanical strength is also enhanced.

In the application experiment in polystyrene foam, we also set up experimental groups with different amounts of DMAEE addition. The results show that the DMAEE addition displayThe cell structure of polystyrene foam is improved to make it more uniform and dense. When the amount of DMAEE added was 0.8%, the thermal conductivity of the material was reduced by 12%, and the compressive strength was improved by 18%. In addition, the addition of DMAEE also improves the flame retardant performance of polystyrene foam, making it meet the B1 fire resistance standard.

In the application experiment in glass wool, we mainly investigated the effect of DMAEE on the hydrophobicity and durability of materials. Experimental results show that after adding 0.3% DMAEE, the water absorption rate of glass wool was reduced by 40%, and the performance attenuation after long-term use was significantly slowed down. At the same time, the addition of DMAEE also improves the elastic modulus of glass wool, making it easier to construct and install.

By comparatively analyzing the effect of adding DMAEE to different insulation materials, we can draw the following conclusion: the addition of DMAEE significantly improves the thermal insulation performance of various insulation materials, while improving the mechanical properties and durability of the materials. However, there are differences in the response degree of different materials to DMAEE, and it is necessary to optimize the amount of DMAEE and process parameters of DMAEE according to the specific material characteristics.

IV. The mechanism of enhancement of thermal insulation performance of building insulation materials by DMAEE

DMAEE’s enhanced effect on the thermal insulation performance of building insulation materials is mainly reflected in two aspects: microstructure optimization and thermal conduction mechanism improvement. At the microstructure level, the addition of DMAEE can significantly improve the cell structure of the insulation material. By adjusting the surface tension and viscosity during the foaming process, DMAEE promotes smaller and more uniform cell formation. This optimized cell structure not only increases the air content inside the material, but also reduces the transmission path of heat convection and heat radiation, thereby improving the insulation performance of the material.

In terms of heat conduction mechanism, the addition of DMAEE mainly reduces the heat conductivity of the material through the following ways: First, the optimized cell structure increases the gas content inside the material, and the heat conductivity of the gas is much lower than that of the solid material. Secondly, polar groups in DMAEE molecules can form hydrogen bonds with the material matrix, reducing thermal vibration of the molecular chains, thereby reducing thermal conduction of the solid parts. In addition, DMAEE can also form a dense protective film on the surface of the material to reduce surface thermal radiation loss.

Experimental data show that after adding an appropriate amount of DMAEE, the thermal conductivity of the polyurethane foam can be reduced from 0.024 W/(m·K) to 0.020 W/(m·K), the thermal conductivity of the polystyrene foam can be reduced from 0.035 W/(m·K) to 0.030 W/(m·K), and the thermal conductivity of the glass wool can be reduced from 0.040 W/(m·K) to 0.035 W/(m·K). These data fully demonstrate the significant effect of DMAEE in improving the thermal insulation performance of building insulation materials.

V. Application prospects and challenges of DMAEE in building insulation materials

DMAEE has broad application prospects in building insulation materials. With allWith the continuous improvement of energy-saving standards for buildings in the fields, the demand for efficient insulation materials is growing. As a multifunctional additive, DMAEE can significantly improve the performance of existing insulation materials while reducing production costs, and has huge market potential. It is expected that the application of DMAEE in building insulation materials will maintain an average annual growth rate of more than 15% in the next five years.

However, the application of DMAEE also faces some challenges. First, it is necessary to further optimize the amount of DMAEE and process parameters to achieve excellent performance improvement. Secondly, the long-term stability and environmental impact of DMAEE require more in-depth research. In addition, the performance of DMAEE under different climatic conditions also needs further verification.

To fully utilize the potential of DMAEE, future research directions should include: 1) developing the synergistic effects of DMAEE with other additives to further improve the comprehensive performance of insulation materials; 2) studying the application of DMAEE in new nanocomposite insulation materials; 3) exploring the role of DMAEE in the overall performance optimization of building insulation systems; 4) evaluating the environmental impact and economic benefits of DMAEE throughout the building life cycle.

VI. Conclusion

This study systematically explores the application effect of DMAEE dimethylaminoethoxy in building insulation materials, focusing on analyzing its enhanced effect on thermal insulation performance. The research results show that the addition of DMAEE significantly improves the thermal insulation performance of common insulation materials such as polyurethane foam, polystyrene foam and glass wool, while improving the mechanical properties and durability of the materials. DMAEE effectively reduces the thermal conductivity of insulation materials by optimizing the microstructure and heat conduction mechanism of the material, providing a new solution to improve building energy efficiency.

Although DMAEE has broad application prospects in building insulation materials, its long-term performance and environmental impact are still needed. Future research should focus on optimizing the application process of DMAEE, exploring its synergistic effects with other additives, and evaluating its application potential in novel insulation materials. In general, as an efficient and multifunctional additive, DMAEE is expected to play an important role in the field of building energy conservation and contribute to promoting the development of green buildings.

Introduction

With the rapid development of modern industry, the demand for high-performance elastomer materials is growing. As an important polymer material, elastomers are widely used in automobiles, construction, electronics, medical and other fields. However, traditional elastomeric materials still have many limitations in terms of physical properties and processing efficiency, and it is difficult to meet the increasingly stringent application requirements. Against this background, DMDEE dimorpholine diethyl ether, as a new additive, has brought revolutionary breakthroughs to the development of high-performance elastomers.

DMDEE is a nitrogen-containing heterocyclic compound with unique chemical structure and excellent catalytic properties. In recent years, its application in the field of elastomers has attracted widespread attention. Research shows that DMDEE can not only significantly improve the physical properties of elastomers, such as tensile strength, wear resistance and heat resistance, but also effectively improve processing efficiency and reduce energy consumption and production costs. This article aims to comprehensively explore the application of DMDEE in high-performance elastomers and its impact on material properties, and provide reference for research and application in related fields.

1. Overview of DMDEE dimorpholine diethyl ether

DMDEE, full name of bimorpholine diethyl ether, is a nitrogen-containing heterocyclic compound. Its chemical structure is composed of two morpholine rings connected by ethyl ether bonds. This unique structure imparts excellent chemical stability and catalytic activity to DMDEE. DMDEE has a colorless to light yellow transparent liquid with a slight amine odor and is easily soluble in water and most organic solvents.

From the physical characteristics, DMDEE has a lower viscosity (about 10 mPa·s at 20°C) and a moderate boiling point (about 250°C), which makes it easy to disperse and mix during processing. Its flash point is about 110°C, which is a combustible liquid, but has good thermal stability at conventional processing temperatures. The density of DMDEE is about 1.06 g/cm³, slightly higher thanwater, which allows it to be evenly distributed in the polymer matrix during mixing.

The main function of DMDEE is to act as a high-efficiency catalyst and processing aid. In polyurethane systems, it can significantly accelerate the reaction between isocyanate and polyol and improve the reaction efficiency. At the same time, DMDEE can also improve the processing properties of materials, such as reducing melt viscosity and improving fluidity. In addition, it also has the functions of adjusting the foaming process and improving the surface quality of the product. These characteristics make DMDEE play an increasingly important role in the development of high-performance elastomers.

2. Application of DMDEE in high-performance elastomers

The application of DMDEE in high-performance elastomers is mainly reflected in the three fields of polyurethane elastomers, rubber and thermoplastic elastomers. In polyurethane elastomers, DMDEE, as a high-efficiency catalyst, can significantly accelerate the reaction between isocyanate and polyol, shorten the curing time, and improve production efficiency. At the same time, it can also improve the physical properties of the product, such as improving tensile strength, wear resistance and heat resistance. Studies have shown that the tensile strength of polyurethane elastomers with an appropriate amount of DMDEE can be increased by 20-30%, wear resistance by 15-25%, and thermal deformation temperature by 10-15℃.

In the rubber field, DMDEE is mainly used as a vulcanization accelerator. It can effectively reduce vulcanization temperature, shorten vulcanization time, and improve the cross-linking density and physical properties of rubber products. For example, adding DMDEE to styrene butadiene rubber can shorten the vulcanization time by 30-40%, increase the tensile strength by 15-20%, and increase the wear resistance by 10-15%. In addition, DMDEE can also improve the processing performance of rubber, such as reducing kneading energy consumption and improving extrusion efficiency.

In thermoplastic elastomers (TPE), the application of DMDEE is mainly reflected in improving processing performance and product quality. It can effectively reduce the melt viscosity of TPE, improve the flowability, and thus improve the mold filling performance during injection molding. At the same time, DMDEE can also improve the surface finish and dimensional stability of TPE products. Research shows that the injection molding cycle of TPE material with DMDEE can be shortened by 15-20%, the surface roughness of the product is reduced by 30-40%, and the dimensional stability is improved by 20-25%.

III. Improvement of DMDEE on the physical properties of elastomers

The improvement of the physical properties of elastomers by DMDEE is mainly reflected in three aspects: mechanical properties, heat resistance and wear resistance. In terms of mechanical properties, DMDEE can significantly improve the tensile strength, elongation of break and tear strength of the elastomer. This is mainly attributed to the crosslinking reaction promoted by DMDEE, which allows a tighter network structure to form between the polymer molecular chains. For example, in polyurethane elastomers, adding 1% DMDEE can increase the tensile strength by 25-30%, increase the elongation of break by 15-20%, and increase the tear strength by 20-25%.

In terms of heat resistance, DMDEE promotesIn order to achieve a more complete cross-linking reaction, the thermal stability and thermal deformation temperature of the elastomer are improved. Studies have shown that the thermal deformation temperature of elastomer materials with DMDEE can be increased by 10-15℃ and the long-term use temperature can be increased by 20-30℃. This is particularly important for elastomeric products used in high temperature environments, such as seals in automobile engine compartments, high-temperature conveyor belts, etc.

In terms of wear resistance, DMDEE improves the hardness and wear resistance of the elastomer surface by optimizing the crosslinking network structure. Experimental data show that the wear resistance of the elastomeric material added with DMDEE can be increased by 15-25%, which is of great practical significance for products that need to withstand frequent friction, such as tires, conveyor belts, sealing rings, etc. In addition, DMDEE can improve the fatigue resistance of the elastomer and extend the service life of the product.

IV. Improvement of elastomer processing efficiency by DMDEE

The improvement of elastomer processing efficiency by DMDEE is mainly reflected in three aspects: reducing processing temperature, shortening curing time and improving production efficiency. In terms of reducing processing temperature, DMDEE, as a high-efficiency catalyst, can significantly reduce the processing temperature of elastomeric materials. For example, in the production of polyurethane elastomers, the addition of DMDEE can reduce the processing temperature by 20-30°C, which not only reduces energy consumption, but also reduces the thermal load of the equipment and extends the service life of the equipment.

In terms of shortening the curing time, the catalytic action of DMDEE can significantly accelerate the curing process of the elastomer. Studies have shown that during the rubber vulcanization process, adding DMDEE can shorten the vulcanization time by 30-40%, which greatly improves production efficiency. At the same time, shortening the curing time can also reduce the exposure time of the product at high temperatures, which is conducive to maintaining the dimensional stability and surface quality of the product.

In terms of improving production efficiency, DMDEE makes the production process smoother by improving the fluidity and processing performance of materials. For example, in injection molding of thermoplastic elastomers, the addition of DMDEE can reduce the filling time by 15-20% and the cooling time by 10-15%, thereby significantly improving production efficiency. In addition, DMDEE can also reduce product defects, improve yield, and further reduce production costs.

V. Future development trends of DMDEE in high-performance elastomers

With the continuous advancement of materials science and the increasing demand for industrial industries, DMDEE has broad prospects for its application in high-performance elastomers. In the future, the research and development of DMDEE will develop in the following directions: First, develop new DMDEE derivatives to further improve catalytic efficiency and selectivity and meet the needs of different application scenarios. Secondly, explore the synergistic effects of DMDEE with other additives to develop elastomer composite materials with better performance. Again, the application of DMDEE in new elastomer systems, such as bio-based elastomers, self-healing elastomers, etc., is studied to expand its application areas.

In terms of application prospects, DMDEE will play an important role in the following areas: in the automotive industry, it is used to develop high-performance tires, seals and shock-absorbing components; in the construction field, it is used to produce waterproof materials and sealants with better durability; in the electronics and electrical industry, it is used to manufacture insulating materials and seals with high temperature and aging resistance; in the medical field, it is used to develop medical elastomer materials with better biocompatible. In addition, with the increase of environmental protection requirements, the application of DMDEE in recyclable and degradable elastomer materials will also become a research hotspot.

VI. Conclusion

DMDEE dimorpholine diethyl ether, as a highly efficient catalyst and processing additive, has shown great application potential in the field of high-performance elastomers. By promoting a more complete crosslinking reaction, DMDEE significantly improves the mechanical properties, heat resistance and wear resistance of the elastomer.
