1. Introduction

Soft foam products are widely used in furniture, automobiles, packaging and other fields. The optimization of their production process is of great significance to improving product quality and reducing production costs. As a highly efficient catalyst, amine catalyst CS90 plays a key role in the production of soft foam products. This article will introduce in detail how to use the amine catalyst CS90 to optimize the production process of soft foam products, from raw material selection to finished product inspection, and provide comprehensive guidance.

2. Overview of soft foam products

Soft foam products are mainly made of polyurethane materials, and have the advantages of lightweight, good elasticity, sound absorption and heat insulation. Common soft foam products include sofa cushions, mattresses, car seats, etc. Its production process mainly includes steps such as raw material mixing, foaming, maturation, and cutting.

3. Characteristics of amine catalyst CS90

Amine catalyst CS90 is a highly efficient and environmentally friendly catalyst with the following characteristics:

High-efficiency catalysis: significantly improve the reaction speed and shorten the production cycle.
Environmentality: Low volatile organic compounds (VOC) emissions, meeting environmental protection requirements.
Stability: Stabilizes within a wide temperature range and is suitable for a variety of production processes.
Compatibility: Compatible with a variety of polyurethane raw materials, easy to mix.

4. Raw material selection

4.1 Polyether polyol

Polyether polyol is one of the main raw materials for soft foam products, and its choice directly affects the performance of the product. Commonly used polyether polyols include:

Highly reactive polyether polyol: Suitable for highly elastic foam products.
Low-reactive polyether polyol: Suitable for low-density foam products.

4.2 Isocyanate

Isocyanate is another main raw material for polyurethane reaction. Commonly used isocyanates include:

TDI (diisocyanate): Suitable for highly elastic foam products.
MDI (Diphenylmethane diisocyanate): Suitable for high-density foam products.

4.3 Amine Catalyst CS90

The amount of amine catalyst CS90 is usually 0.1%-0.5% of the total raw material, and the specific amount needs to be adjusted according to the production process and product requirements.

4.4 Other additives

Foaming agent: such as water, physical foaming agent, etc.
Stabler: Such as silicone oil, used to stabilize foam structure.
Flame Retardant: Improves the flame retardant performance of the product.

5. Production process optimization

5.1 Raw material mixing

Raw material mixing is the first step in the production of soft foam products, and it is crucial to ensure that the components are mixed evenly. The specific steps are as follows:

Weighing raw materials: Weigh each component accurately according to the formula.
Premix: Premix the polyether polyol, amine catalyst CS90, foaming agent, stabilizer, etc. in advance.
Add isocyanate: Mix the premix with isocyanate and stir well.

5.2 Foaming

The foaming process is a key step in molding soft foam products. Optimizing the foaming process can improve product quality. Specific optimization measures include:

Control temperature: The foaming temperature is usually controlled at 20-30℃. Too high or too low will affect the foaming effect.
Adjust the amount of catalyst: Adjust the amount of amine catalyst CS90 according to product requirements and control the foaming speed.
Optimize stirring speed: The stirring speed affects the size and distribution of bubbles and needs to be adjusted according to product requirements.

5.3 Cultivation

The maturation process is a key step in curing foam products. Optimizing the maturation process can improve the mechanical properties of the product. Specific optimization measures include:

Control the maturation temperature: The maturation temperature is usually controlled at 50-70℃. Too high or too low will affect the maturation effect.
Adjust the maturation time: According to the product requirementsPlease adjust the maturation time, usually 24-48 hours.

5.4 Cutting

The mature foam products need to be cut to meet different application needs. Optimization of cutting process can improve production efficiency and product accuracy. Specific optimization measures include:

Select the appropriate cutting equipment: such as CNC cutting machine to improve cutting accuracy.
Optimize cutting parameters: such as cutting speed, cutting pressure, etc. to ensure cutting quality.

6. Finished product inspection

6.1 Physical performance inspection

Physical properties are important indicators of soft foam products. Common inspection items include:

Density: measured by weighing method, in kg/m³.
Hardness: Measured by a hardness meter, unit in Shore A.
Tenable strength: measured by a tensile testing machine, unit in MPa.
Elongation of Break: Measured by a tensile tester, in %.

6.2 Chemical performance inspection

Chemical performance inspection mainly focuses on the environmental protection and durability of the product. Common inspection items include:

VOC emissions: measured by gas chromatography in mg/m³.
Fire retardant performance: measured by vertical combustion test, in seconds.

6.3 Appearance Inspection

Appearance inspection mainly focuses on the appearance quality of the product. Common inspection items include:

Surface Flatness: Through visual inspection, ensure that the surface is free of unevenness.
Bubble Distribution: Check through microscopy to ensure that the bubbles are evenly distributed.

7. Conclusion

Using the amine catalyst CS90 to optimize the production process of soft foam products can significantly improve product quality and production efficiency. By rationally selecting raw materials, optimizing production processes, and strictly inspecting finished products, high-performance and environmentally friendly soft foam products can be produced. I hope that the detailed guidance and rich content provided in this article can provide valuable reference for related manufacturers.
