How to use polyurethane sponge softener to optimize the production process of soft foam products: from raw material selection to finished product inspection

Introduction

Polyurethane soft foam products are widely used in furniture, car seats, mattresses and other fields due to their excellent elasticity, comfort and durability. However, to produce high-quality soft foam products, not only precise process control is required, but also scientific selection and optimization of raw materials are required. Among them, polyurethane sponge softener, as a key additive, has an important impact on the softness, resilience, durability and other properties of the foam. This article will discuss in detail how to use polyurethane sponge softener to optimize the production process of soft foam products from multiple aspects such as raw material selection, production process optimization, and finished product inspection.

1. Raw material selection and proportion optimization

Polyurethane sponge softener is a surfactant that mainly improves the fluidity of the foam by reducing the surface tension of the foam system, thereby improving the softness and resilience of the foam. Its mechanism of action mainly includes the following aspects:

  • Reduce surface tension: Softeners can reduce the surface tension of the foam system, making bubbles more likely to form and exist stably.
  • Improving fluidity: By reducing viscosity, softeners can make the foam system flow more evenly during the foaming process, reducing the bursting and merger of bubbles.
  • Enhanced elasticity: Softeners can interact with the polyurethane molecular chain, enhance the elastic modulus of the foam and improve elasticity.

1.2 Raw material selection

In the production of soft foam products, the selection of raw materials is crucial. The following are several key raw materials and their selection criteria:

Raw Material Type Select criteria Common brands/models
Polyether polyol Molecular weight is moderate, hydroxyl value range is between 28-56 mgKOH/g, and viscosity is moderate BASF Lupranol, Dow Voranol
Isocyanate Select MDI or TDI, the NCO content is between 30-35%, and the reaction activity is moderate BASF Lupranate, Dow Isonate
Catalyzer Select amine or tin catalysts,Moderate reaction speed, avoid too fast or too slow Air Products Dabco, Evonik Kosmos
Frothing agent Choose water or physical foaming agents (such as HCFC, HFC, etc.), with high foaming efficiency and good environmental protection performance Honeywell Solstice, Arkema Forane

Polyurethane sponge softener is a chemical additive specially designed for improving the softness and elasticity of polyurethane sponges. 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:

  1. 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.
  2. 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.
  3. 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

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
Polyether softener 0.028

It can be seen from Table 2 that different types of softeners have different effects on the thermal conductivity of polyurethane sponges, among which polyether softeners have good effects.

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.

III. Selection and application of polyurethane sponge softener
