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

1.1 The mechanism of action of polyurethane sponge softener

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
Softening Select a special softener for polyurethane, with moderate molecular weight, good compatibility with the system, and high stability Evonik Tego, Momentive Silsoft

1.3 Ratio optimization

The ratio of raw materials directly affects the performance of the foam. The following are the common raw material ratio range:

Raw Materials Rating range (parts by weight) Remarks
Polyether polyol 100 Benchmark raw materials
Isocyanate 40-60 Adjust according to hydroxyl value and NCO content
Water 2-5 Footing agent, the amount of the foam affects the density of the foam
Catalyzer 0.1-0.5 Adjust according to the reaction speed
Softening 1-3 Adjust to foam softness requirements
Other additives 0.5-2 such as flame retardants, antioxidants, etc.

2. Production process optimization

2.1 Foaming process control

The foaming process is the core link in the production of soft foam and directly affects the structure and performance of the foam. The following are the key control points of the foaming process:

Process Parameters Control Range Impact
Mixing Temperature 20-30? Temperature too high will lead to excessive reaction, and temperature too low will lead to insufficient reaction
Agitation speed 1000-3000 rpm The stirring speed affects the uniformity of the bubbles, and too high will cause the bubbles to burst
Foaming time 5-10 minutes The foaming time is too short, which will lead to uneven foam density, and too long may lead to foam collapse
Mature temperature 50-80? The maturation temperature affects the degree of crosslinking of the foam. Too high temperature may cause the foam to harden
Mature Time 2-4 hours The maturation time is too short, which will lead to insufficient foam strength, and too long may affect production efficiency

2.2 How to add softener

The addition of softener has a significant impact on foam performance. Common ways to add include:

  • Premix method: Premix the softener with polyether polyol in advance, and then perform a foaming reaction. This method can ensure that the softener is evenly dispersed in the system and is suitable for large-scale production.
  • Post addition method: After the foaming reaction reaches a certain level, add a softener. This method is suitable for occasions where there are special requirements for foam softness, but it is difficult to operate.

2.3 Process Optimization Example

The following is a typical soft foam production process optimization example:

Process Steps Pre-optimization parameters Optimized parameters Optimization effect
Mixing Temperature 25? 22? Reduce the reaction speed and reduce bubble burst
Agitation speed 2000 rpm 2500 rpm Improve bubble uniformity and reduce bubble density differences
Software addition method Add method Premix method Improve the uniformity of softener dispersion and improveFoam softness
Mature temperature 70? 60? Reduce the maturation temperature to prevent the foam from becoming harder

3. Finished product inspection and quality control

3.1 Physical performance test

The physical properties of soft foam products are an important indicator for measuring their quality. The following are common physical performance testing items:

Test items Testing Standards Qualification Range Remarks
Density ASTM D3574 20-50 kg/m³ Often the density may lead to insufficient foam strength, and too high may affect softness
Resilience ASTM D3574 ?40% Low resilience may shorten the service life of the foam
Tension Strength ASTM D3574 ?80 kPa Tension strength is too low may cause the foam to tear
Tear Strength ASTM D3574 ?2 N/cm Tear strength is too low may cause the foam to burst
Compression permanent deformation ASTM D3574 ?10% Overlasting compression deformation may cause the foam to lose elasticity

3.2 Chemical performance test

The chemical properties of soft foam products directly affect their durability and safety. The following are common chemical performance testing items:

Test items Testing Standards Qualification Range Remarks

Formaldehyde emission GB 18587 ?0.05 mg/m³ Excessive formaldehyde emission may cause harm to human health
Flame retardant performance GB 8624 Level B1 Unqualified flame retardant performance may lead to fire hazards

3.3 Finished product inspection process

The following is the finished product inspection process for soft foam products:

  1. Sampling: Randomly sampled from the production line to ensure that the sample is representative.
  2. Physical Performance Test: According to standard testing methods, the density, resilience, tensile strength, tear strength, permanent compression deformation of the sample is tested.
