The selection of each raw material must be optimized according to the performance requirements of the final product.

Polyols are one of the main components of polyurethane foams, and their type and molecular weight directly affect the hardness, elasticity and durability of the foam. Commonly used polyols include polyether polyols and polyester polyols. Polyether polyols have good hydrolysis stability and low temperature flexibility, and are suitable for the production of high elastic foams; while polyester polyols have high mechanical strength and heat resistance, and are suitable for the production of high hardness foams. When choosing a polyol, parameters such as its hydroxyl value, molecular weight distribution and functionality need to be considered.

Isocyanate is another key raw material. Commonly used isocyanates include TDI (diisocyanate) and MDI (diphenylmethane diisocyanate). TDI has high reactivity and is suitable for the production of low-density foams; while MDI has high mechanical strength and heat resistance, is suitable for the production of high-density foams. When choosing isocyanate, factors such as NCO content, reaction activity and toxicity need to be considered.

Catalytics play a crucial role in the production of polyurethane foam. As a highly efficient catalyst, DMDEE can significantly accelerate the reaction between isocyanate and polyol, shorten the reaction time and improve production efficiency. In addition, DMDEE also has a selective catalytic effect, which can preferentially catalyze the reaction of isocyanate with water to form carbon dioxide gas, thereby forming a uniform bubble structure in the foam. In formula design, the amount of DMDEE is usually 0.1% to 0.5% of the weight of the polyol, and the specific amount needs to be adjusted according to production conditions and product requirements.

Foaming agents are important factors affecting foam density and structure. Commonly used foaming agents include water, physical foaming agents (such as HCFC, HFC) and chemical foaming agents (such as ammonium bicarbonate). Water is a commonly used foaming agent that reacts with isocyanate to form carbon dioxide gas and forms foam structure. Physical foaming agents generate gases through evaporation to form foam. When choosing a foaming agent, it is necessary to consider factors such as its foaming efficiency, environmental protection and cost.

Stablers and flame retardants are important additives to improve foam stability and safety. Stabilizers can prevent foam from collapsing during molding, and commonly used stabilizers include silicone surfactants. Flame retardants can improve the flame retardant performance of foams. Commonly used flame retardants include phosphorus-based flame retardants and halogen-based flame retardants. existWhen choosing stabilizers and flame retardants, factors such as their compatibility with raw materials, added amount and environmental protection should be considered.

In formula design, various raw materials need to be reasonably selected and matched according to the performance requirements of the final product. For example, when producing high elastic foam, high hydroxyl value polyether polyol and TDI can be selected, and an appropriate amount of DMDEE catalyst and water foaming agent can be added; when producing high hardness foam, high hydroxyl value polyester polyol and MDI can be selected, and an appropriate amount of DMDEE catalyst and physical foaming agent can be added. By optimizing the formulation design, the physical properties of the foam such as density, hardness, elasticity and durability can be effectively controlled to meet the needs of different application fields.

3. Production process optimization

In the production process of soft polyurethane foam, optimization of production process is the key to improving product quality and production efficiency. As an efficient catalyst, DMDEE plays a crucial role in the optimization of production process. The following will discuss in detail how to use DMDEE to optimize the production process from key steps such as mixing, foaming, and maturation.

Mixing is the first step in the production of polyurethane foam. Its purpose is to evenly mix raw materials such as polyols, isocyanates, catalysts, foaming agents, stabilizers and flame retardants. During the mixing process, the amount of DMDEE added and mixing speed have a significant impact on the reaction rate and foam structure. Generally, the amount of DMDEE is added to 0.1% to 0.5% by weight of the polyol, and the specific amount needs to be adjusted according to production conditions and product requirements. The mixing speed should be controlled within an appropriate range. Too fast or too slow will affect the mixing effect and reaction rate. By optimizing the addition amount and mixing speed of DMDEE, uniform mixing of raw materials can be achieved and reaction efficiency can be improved.

Foaming is the core step in the production of polyurethane foam. Its purpose is to generate carbon dioxide gas through chemical reactions to form foam structures. During the foaming process, the selective catalytic action of DMDEE can preferentially catalyze the reaction of isocyanate with water to form carbon dioxide gas, thereby forming a uniform bubble structure in the foam. Foaming temperature and time are important factors affecting the foam structure. Generally, the foaming temperature is controlled between 20°C and 40°C, and the foaming time is controlled between 1 and 5 minutes. By optimizing the addition amount and foaming conditions of DMDEE, the density and structure of the foam can be effectively controlled and product quality can be improved.

Mature is the next step in the production of polyurethane foam, and the purpose is to completely cure the foam by heating, improving its mechanical properties and stability. During the maturation process, the amount of DMDEE added and the maturation temperature have a significant impact on the curing speed and performance of the foam. Typically, the maturation temperature is controlled between 80°C and 120°C and the maturation time is controlled between 1 and 3 hours. By optimizing the addition amount and maturation conditions of DMDEE, the curing speed of the foam can be accelerated and its mechanical properties and stability can be improved.

In actual production, adjustments and optimizations are also required based on specific equipment and process conditions. For example, in a continuous production line, the originalThe conveying speed and mixing ratio of the material ensure the stability of the reaction system; in the batch production line, the raw material usage and reaction time of each production need to be controlled to ensure the consistency of product quality. Through the system’s process optimization, the efficient and stable production of soft polyurethane foam can be achieved, meeting the needs of different application fields.

IV. Finished product inspection and quality control

In the production process of soft polyurethane foam, finished product inspection and quality control are key links to ensure product performance and safety. Through systematic inspection methods and strict quality control measures, the physical, chemical and safety of the product can be effectively evaluated to ensure that it complies with relevant standards and application requirements.

Physical performance inspection is an important means to evaluate the quality of polyurethane foam, mainly including indicators such as density, hardness, elasticity, permanent compression deformation and tensile strength. Density is an important parameter for measuring the quality of foam. It is usually measured by the weight method, that is, the weight of a foam per unit volume is measured. Hardness is an important indicator to measure the softness of foam. It is usually measured by a hardness meter. Commonly used hardness units include Shore hardness and indentation hardness. Elasticity is an important indicator for measuring the rebound performance of foam. It is usually measured by a rebound meter to measure the rebound height of the foam after being impacted. Compression permanent deformation is an important indicator for measuring the durability of foam. It is usually measured using a compression permanent deformation meter to measure the degree of recovery of the foam after a long period of compression. Tensile strength is an important indicator for measuring the tensile properties of foam. It is usually measured by tensile testing machines to measure the high stress of the foam during the tensile process.

Chemical performance inspection is an important means to evaluate the stability and safety of polyurethane foam, mainly including hydrolysis resistance, heat resistance and aging resistance. Hydrolysis resistance is an important indicator to measure the stability of foam in humid environments. It is usually measured by humidity and heat aging test to measure the performance changes of foam in high temperature and high humidity environments. Heat resistance is an important indicator to measure the stability of foam in high-temperature environments. It is usually measured by thermal aging test to measure the performance changes of foam in high-temperature environments. Aging resistance is an important indicator to measure the stability of foam during long-term use. UV aging test is usually used to measure the performance changes of foam under ultraviolet light.

Safety inspection is an important means to evaluate the safety of polyurethane foam to the human body and the environment, mainly including indicators such as flame retardant, volatile content and toxicity. Flame retardancy is an important indicator for measuring the fire resistance of foam. It is usually measured by vertical combustion tests and horizontal combustion tests to measure the combustion performance of foam under the action of flame. Volatile content is an important indicator to measure the volatile organic content in foam. It is usually measured by gas chromatography to measure the volatile organic content released by the foam at high temperatures. Toxicity is an important indicator to measure the impact of bubbles on human health. It is usually measured by animal tests and cell tests to measure the impact of harmful substances in bubbles on the human body.

In the process of finished product inspection, it must be based on the relevant standardsand to formulate detailed inspection plans and quality control measures. For example, in the production of polyurethane foam for furniture, physical properties such as density, hardness, elasticity, compression permanent deformation and tensile strength must be inspected according to the standard of GB/T 10802-2006 “Soft Polyurethane Foam Plastics”; in the production of polyurethane foam for car seats, safety inspections such as flame retardancy and volatile content must be carried out according to the standard of GB/T 2408-2008 “Determination of Plastics Combustion Performance” of GB/T 2408-2008 “Determination of Plastics Combustion Performance” are required. Through the system’s finished product inspection and strict quality control, the performance and safety of soft polyurethane foam can be ensured and meet the needs of different application fields.

The core value of polyurethane tension agents in thermal insulation material manufacturing: Optimizing thermal insulation effect and reducing material waste

Introduction

Hello everyone! Today we are going to talk about a topic that sounds a bit “high-end” but is actually very down-to-earth – the core value of polyurethane tension agents in the manufacturing of insulation materials. Don’t be scared by the word “polyurethane”, it is actually an important part of the common insulation materials in our daily lives. Today, I will use easy-to-understand language to show you how polyurethane tension agents can optimize thermal insulation, reduce material waste, and even save you money! Ready? Let’s get started!

1. What is polyurethane tension agent?

1.1 Basic concepts of polyurethane

First, let’s get to know polyurethane. Polyurethane (PU) is a polymer material that is widely used in construction, furniture, automobiles, footwear and other fields. Its characteristics are lightweight, wear-resistant, corrosion-resistant, and importantly – it has good thermal insulation properties.

1.2 Effect of tension agent

So, what is a tensile agent? Simply put, tensile agent is an additive used to improve the mechanical properties of materials, especially tensile strength and elasticity. In polyurethane materials, the tensile agent acts like a “fitness coach”, helping the material become more “stronger” and more “elastic”.

1.3 Definition of polyurethane tension agent

Polyurethane tension agent, as the name implies, is a tension agent specially used for polyurethane materials. It improves the tensile strength, elastic modulus and tear resistance of the material by changing the molecular structure of polyurethane, thereby optimizing the overall performance of the insulation material.

2. Application of polyurethane tension agent in thermal insulation materials

2.1 Basic requirements for insulation materials

The main function of thermal insulation materials is to reduce heat transfer and maintain the indoor temperature stable. Therefore, an ideal insulation material needs to have the following characteristics:

Low thermal conductivity: Heat is not easily transferred through the material.
High tensile strength: The material is not easy to break or deform.
Good elasticity: The material can adapt to various shapes and stresses.
Durability: The material can maintain stable performance for a long time.

2.2 How to optimize thermal insulation effect of polyurethane tension agent

Polyurethane tension agent optimizes the insulation effect of insulation materials through the following methods:

2.2.1 Improve the closed porosity of the material

Closed porosity refers to the sealing of the materialThe proportion of pores. The more pores, the lower the thermal conductivity and the better the thermal insulation effect. Polyurethane tensile agents can promote the formation of more closed pores in the polyurethane material, thereby improving thermal insulation performance.

2.2.2 Tensile strength of reinforced materials

Materials with high tensile strength are not prone to breaking, which can better maintain their structural integrity. Polyurethane tensile agents enhance the interaction force between molecules, improve the tensile strength of the material, and ensure that the insulation material is not easily damaged during long-term use.

2.2.3 Improve the elasticity of the material

The elastic materials can better adapt to temperature changes and mechanical stresses, reducing the risk of cracking and deformation. Polyurethane tensile agents improve their elastic modulus by adjusting the molecular structure of the material, making the insulation material more durable.

2.3 How to reduce material waste by polyurethane tension agents

In addition to optimizing thermal insulation, polyurethane tension agents can also help reduce material waste. Specifically, it is implemented in the following ways:

2.3.1 Improve material utilization

Polyurethane tensile agents can improve the processing properties of materials and make them easier to form and cut. This means that during the production process, the material is more utilizing and there is less waste.

2.3.2 Extend the service life of the material

Because polyurethane tensile agent improves the tensile strength and elasticity of the material, the service life of the insulation material is extended. This means that less material needs to be replaced within the same time, thus reducing material waste.

2.3.3 Reduce energy consumption in the production process

Polyurethane tensile agent can optimize the processing technology of materials and reduce energy consumption during production. This not only reduces production costs, but also reduces the negative impact on the environment.

III. Product parameters of polyurethane tension agent

To better understand the performance of polyurethane tensile agent, let’s take a look at its main product parameters. The following is a typical polyurethane tensioner product parameter list:

parameter name	Value Range	Instructions
Density (g/cm³)	0.9 – 1.2	The density of the material affects its weight and strength
Tension Strength (MPa)	10 – 30	The material’s large bearing capacity in the stretched state
Modulus of elasticity (MPa)	100 – 500	The stiffness of the material within the elastic deformation range
Thermal conductivity (W/m·K)	0.02 – 0.03	The thermal conductivity of the material, the lower the thermal insulation effect, the better
Closed porosity (%)	90 – 95	The ratio of closed air holes in the material, the higher the heat insulation effect, the better
Service life (years)	20 – 30	The life expectancy of the material under normal use conditions

3.1 Density

Density is the basic physical parameter of a material that affects its weight and strength. The density of polyurethane tensile agents is usually between 0.9 – 1.2 g/cm³, which means it is both light and sturdy and is ideal for use in insulation materials.

3.2 Tensile strength

Tension strength is the material’s large bearing capacity in the tensile state. The tensile strength of polyurethane tensile agent is between 10 – 30 MPa, which means it can withstand a large tension and is not prone to breaking.

3.3 Elastic Modulus

The elastic modulus is the stiffness of the material within the elastic deformation range. The elastic modulus of polyurethane tensile agent is between 100 – 500 MPa, which means it has good elasticity and is able to adapt to various shapes and stresses.

3.4 Thermal conductivity

The thermal conductivity is the thermal conductivity of the material, and the lower the heat insulation effect, the better. The thermal conductivity of the polyurethane tensile agent is between 0.02 – 0.03 W/m·K, which means it has excellent thermal insulation properties.

3.5 Coverage rate

The closed pore ratio is the proportion of closed pores in the material, and the higher the heat insulation effect, the better. The closed porosity of polyurethane tensile agent is between 90 – 95%, which means it can effectively reduce heat transfer.

3.6 Service life

The service life is the expected lifespan of the material under normal use conditions. The service life of polyurethane tensile agents is between 20-30 years, which means it can maintain stable performance over the long term and reduce replacement frequency.

IV. Advantages and challenges of polyurethane tensioning agents

4.1 Advantages

4.1.1 Excellent thermal insulation performance

Polyurethane tensile agent significantly improves the thermal insulation performance of the insulation material by increasing the closed porosity and reducing the thermal conductivity. This means in the cold winter, your home can be warmer; in hot summers, your home can be cooler.

4.1.2 High tensile strength and elasticity

Polyurethane tensile agent improves the tensile strength and elasticity of the material by enhancing the interaction force between molecules. This means that the insulation material is not prone to breaking or deforming and can maintain its structural integrity for a long time.

4.1.3 Reduce material waste

Polyurethane tensile agent reduces material waste by increasing material utilization and extending service life. This not only reduces production costs, but also reduces the negative impact on the environment.

4.2 Challenge
