As a high-efficiency insulation material, polyurethane sponge is highly favored for its excellent thermal insulation properties, lightweight and easy to process. However, there is a certain contradiction between the softness and thermal insulation properties of polyurethane sponges. How to improve their softness while ensuring thermal insulation properties has become a major challenge in the manufacturing of thermal insulation materials. The introduction of polyurethane sponge softener provides an effective way to solve this problem. This article will discuss in detail the key position of polyurethane sponge softener in thermal insulation material manufacturing, analyze its role in improving thermal insulation performance and reducing costs, and analyze its application effects in depth through rich product parameters and tabular data.

It reduces the rigidity of the material and increases its flexibility by changing the structure and arrangement of the polyurethane molecular chains, thereby improving the comfort and performance of the sponge.

1.2 Mechanism of action

The mechanism of action of polyurethane sponge softener mainly includes the following aspects:

Softening of Molecular Chain: The active ingredients in the softener can react with the polyurethane molecular chain, introduce flexible chain segments, reduce the rigidity of the molecular chain, and thus improve the softness of the material.

Condition of crosslinking degree: By adjusting the crosslinking degree between polyurethane molecular chains, softeners can increase their elasticity without significantly reducing the strength of the material.

Optimization of microporous structure: Softeners can optimize the microporous structure of polyurethane sponges, increase porosity, and improve the thermal insulation performance of the material.

2. Application of polyurethane sponge softener in thermal insulation material manufacturing

The thermal insulation performance of polyurethane sponges mainly depends on their microporous structure and thermal conductivity. Softeners improve thermal insulation performance by optimizing the microporous structure, increasing porosity and reducing thermal conductivity.

2.1.1 Optimization of micropore structure

Softening agents can promote the formation of uniform and fine microporous structures of polyurethane sponges, increase porosity, reduce heat conduction paths, and thus improve thermal insulation performance. Table 1 shows the effects of different softener addition amounts on the porosity and thermal conductivity of polyurethane sponges.

Softile agent addition (%) Porosity (%) Thermal conductivity coefficient (W/m·K)

0 85 0.035

1 88 0.032

2 90 0.030

3 92 0.028

It can be seen from Table 1 that with the increase of softener addition, the porosity of the polyurethane sponge gradually increases, the thermal conductivity gradually decreases, and the thermal insulation performance is significantly improved.

2.1.2 Reduction of thermal conductivity

Softeners reduce the rigidity of the polyurethane molecular chain and reduce the thermal conductivity between the molecular chains, thereby reducing the thermal conductivity of the material. Table 2 shows the effect of different softener types on the thermal conductivity of polyurethane sponges.

Softening agent type Thermal conductivity coefficient (W/m·K)

No softener 0.035

Silicon oil softener 0.032

Ester Softener 0.030

Softile agent addition (%) Production energy consumption (kWh/t) Scrap rate (%)

0 120 5

1 115 4

2 110 3

3 105 2

It can be seen from Table 3 that with the increase in the amount of softener added, the production energy consumption and waste rate gradually decrease, and the production cost decreases significantly.

2.2.2 Reduction in raw material consumption

Softening agent can improve the softness and elasticity of polyurethane sponges and reduce raw material consumption. Table 4 shows the effect of different softener addition amounts on raw material consumption.

Softile agent addition (%) Raw material consumption (kg/t)

0 1000

1 980

2 960

3 940

It can be seen from Table 4 that as the amount of softener is added increases, the consumption of raw materials gradually decreases, and the production cost is further reduced.
