Polyurethane foam is a high-performance material widely used in construction, automobile, furniture and other fields. Its excellent thermal insulation, elasticity and durability make it one of the indispensable materials in modern industry. However, under low temperature environments, the curing process of polyurethane foam is often significantly affected, resulting in reduced production efficiency and unstable product quality. To solve this problem, amine catalysts are widely used in the production of polyurethane foams under low temperature environments as an efficient curing accelerator. This article will discuss in detail how amine catalysts promote rapid curing process in low temperature environments and analyze their performance in practical applications.

2. Basic composition and curing principle of polyurethane foam

The preparation of polyurethane foam mainly depends on two key chemical reactions: the polymerization reaction of isocyanate and polyol (gel reaction) and the foaming reaction of isocyanate and water (foaming reaction). These two reactions together determine the structure and performance of the foam.

Gel Reaction: Isocyanate (R-NCO) reacts with polyol (R’-OH) to form a polyurethane segment, forming a foam framework structure.

Foaming reaction: Isocyanate reacts with water to form carbon dioxide gas, forming a pore structure of the foam.

The rates of both reactions will be significantly reduced in low temperature environments, resulting in extended curing time and reduced foam performance.

3. Mechanism of action of amine catalysts

Amine catalyst is a chemical that accelerates the reaction of isocyanates with polyols or water. Its mechanism of action mainly includes the following aspects:

Reduce the reaction activation energy: The amine catalyst reduces the reaction activation energy by forming an intermediate complex with the reactants, thereby accelerating the reaction rate.

Selective Catalysis: Different types of amine catalysts can selectively accelerate gel reactions or foaming reactions, thereby optimizing the structure and performance of the foam.

Temperature adaptability: Some amine catalysts can still maintain high catalytic activity under low temperature environments to ensure the smooth progress of the curing process.

4. Effect of low temperature environment on the curing of polyurethane foam

The impact of low temperature environment on polyurethane foam curing is mainly reflected in the following aspects:

Reaction rate decreases: Molecular movement slows down at low temperatures, and the collision frequency between reactants decreases, resulting in a significant decrease in the reaction rate.

Ununiform foam structure: Reduced reaction rate may lead to uneven pore distribution of the foam, affecting its thermal insulation and mechanical properties.

Incomplete curing: Under extremely low temperature conditions, the curing reaction may not be fully carried out, resulting in a decrease in the strength and durability of the foam.

5. Optimal design of amine catalysts in low temperature environments

In order to achieve rapid curing of polyurethane foam in low temperature environments, the design of amine catalysts needs to meet the following requirements:

High catalytic activity: The catalyst can maintain a high reaction rate even at low temperatures.

Good selectivity: Be able to selectively accelerate gel reaction or foaming reaction according to actual needs.

Environmental Friendliness: Catalysts should minimize harm to the environment and the human body.

Stability: Stabilize chemical properties during storage and use.

6. Comparison of types and properties of common amine catalysts

The following are several common amine catalysts and their performance comparisons in low temperature environments:

Catalytic Type Catalytic activity (low temperature) Selective Environmental Friendship Stability

Triethylenediamine (TEDA) High Gel Reaction Medium High

Dimethylcyclohexylamine (DMCHA) Medium Foaming Reaction High Medium

Dimethylamine (DMEA) Low Gel Reaction High High

N-methylmorpholine (NMM) Medium Foaming Reaction Medium Medium

7. Practical application cases of rapid curing in low temperature environments

Case 1: Building insulation materials

In cold areas, building insulation materials need to be cured quickly in low temperature environments to ensure construction progress. By using highly active amine catalysts such as TEDA, rapid curing of polyurethane foams can be achieved at -10°C, significantly shortening the construction cycle.

Case 2: Car seat foam

Car seat foam needs to maintain high elasticity and durability in low temperature environments. By optimizing the selection of amine catalysts (such as DMCHA), a uniform foam structure can be achieved at low temperatures, improving seat comfort and service life.
