Research on DMCHA to improve the softness of polyurethane products

DMCHA’s exploration on improving the softness of polyurethane products

Introduction

Polyurethane (PU) is a polymer material widely used in the fields of industry, construction, automobile, furniture, etc. Its excellent physical properties and chemical stability make it an important part of modern materials science. However, the softness of polyurethane products is particularly important in some applications, such as soft foams, elastomers, coatings, etc. To improve the softness of polyurethane products, researchers have continuously explored various additives and modifiers. Among them, N,N-dimethylcyclohexylamine (DMCHA) is a commonly used catalyst and is widely used in the production of polyurethane products. This article will discuss in detail the mechanism, application effect and related parameters of DMCHA in improving the softness of polyurethane products.

1. Factors influencing the softness of polyurethane products

1.1 Molecular Structure

The molecular structure of polyurethane is mainly composed of hard and soft segments. The hard segment is usually formed by reaction of isocyanate and chain extenders such as diols or diamines, while the soft segment is composed of polyether or polyester polyols. Factors such as the ratio of hard and soft segments, molecular weight distribution and crosslinking density directly affect the softness of polyurethane products.

1.2 Crosslinking density

The crosslink density refers to the number of crosslinking points between the polyurethane molecular chains. The higher the crosslinking density, the greater the hardness of the material and the lower the softness. Therefore, the softness of the polyurethane product can be effectively controlled by adjusting the crosslinking density.

1.3 Additives

In the production process of polyurethane products, the type and amount of additives have a significant impact on the performance of the final product. Commonly used additives include catalysts, plasticizers, fillers, etc. Among them, the selection of catalyst has an important influence on the reaction rate, molecular structure and final performance of polyurethane.

2. Basic properties of DMCHA

2.1 Chemical structure

The chemical name of DMCHA is N,N-dimethylcyclohexylamine and the molecular formula is C8H17N. It is a colorless to light yellow liquid with a unique amine odor. The molecular structure of DMCHA contains one cyclohexyl group and two methyl groups, which makes it have good solubility and reactivity.

2.2 Physical Properties

parameters value
Molecular Weight 127.23 g/mol
Boiling point 159-161°C
Density 0.85 g/cm³
Flashpoint 45°C
Solution Easy soluble in organic solvents

2.3 Catalytic properties

DMCHA, as a tertiary amine catalyst, has high catalytic activity. It can effectively promote the reaction between isocyanate and polyol, shorten the reaction time and improve production efficiency. In addition, DMCHA has good selectivity and can exhibit different catalytic effects under different reaction conditions.

3. Application of DMCHA in polyurethane products

3.1 Reaction mechanism

In the production process of polyurethane products, DMCHA mainly participates in the reaction through the following two methods:

  1. Catalyzed the reaction of isocyanate and polyol: DMCHA can accelerate the addition reaction between isocyanate and polyol, forming carbamate bonds. This process is a key step in the formation of polyurethane molecular chains.

  2. Modify the reaction rate: The catalytic activity of DMCHA can be controlled by adjusting its dosage. A moderate amount of DMCHA can make the reaction proceed smoothly and avoid uneven molecular structure caused by excessive reaction.

3.2 Effect on softness

The application of DMCHA in polyurethane products is mainly reflected in the following aspects:

  1. Reduce crosslink density: DMCHA can reduce the crosslink density between polyurethane molecular chains by adjusting the reaction rate. Lower crosslinking density means that the interaction between the molecular chains is weakened, thus allowing the material to exhibit better softness.

  2. Improving molecular structure: The catalytic action of DMCHA helps to form a more uniform molecular structure. A uniform molecular structure can reduce stress concentration inside the material and improve the flexibility and elasticity of the material.

  3. Improving reaction efficiency: The high catalytic activity of DMCHA can shorten the reaction time and improve production efficiency. This not only reduces production costs, but also helps to obtain more stable polyurethane products.

3.3 Application Example

The following are some examples of DMCHA application in different types of polyurethane products:

Product Type DMCHA dosage (%) Softness Improvement Effect
Soft foam 0.5-1.0 Sharp improvement
Elastomer 0.3-0.8 Important improvement

TEDA General
BDMAEE Minimal

4.3 Cost and environmental protectionSex

DMCHA also has certain advantages in terms of cost and environmental protection. Compared with other catalysts, DMCHA has lower production costs and produces fewer harmful substances during use, which meets the environmental protection requirements of modern industry.

5. Application optimization of DMCHA

5.1 Dosage control

The amount of DMCHA has a significant impact on the performance of polyurethane products. Excessive amounts may lead to excessive rapid reactions and uneven molecular structures; while excessively low amounts may lead to incomplete reactions and affect the performance of the final product. Therefore, in actual applications, it is necessary to reasonably control the dosage of DMCHA according to the requirements of the specific product.

5.2 Reaction conditions

Reaction conditions (such as temperature, pressure, stirring speed, etc.) also have an important influence on the catalytic effect of DMCHA. Appropriate reaction conditions can fully exert the catalytic effect of DMCHA and obtain polyurethane products with excellent performance.

5.3 Synergistic effects with other additives

In actual production, DMCHA is usually used in conjunction with other additives (such as plasticizers, fillers, etc.). By optimizing the proportion of various additives, the flexibility and other properties of polyurethane products can be further improved.

6. Conclusion

DMCHA, as an efficient polyurethane catalyst, shows significant advantages in improving the softness of polyurethane products. By reasonably controlling the amount and reaction conditions of DMCHA, the cross-linking density of polyurethane products can be effectively reduced, the molecular structure can be improved, and the softness and elasticity of the material can be improved. In addition, DMCHA also has certain advantages in terms of cost and environmental protection, making it an ideal choice for polyurethane products production.

In practical applications, the dosage, reaction conditions and synergistic effects of DMCHA need to be optimized according to the requirements of the specific product. Through continuous exploration and optimization, DMCHA’s application prospects in polyurethane products will be broader.
