Problems solved by technology

[0002] Sponge products have been gradually popularized in people's lives, including seats, sofas, mattresses and other household items made of sponges. Polyether polyols are the main raw materials for the production of polyurethane sponges. Polyether polyols are generally used in the production of polyurethane sponges. Alcohols usually use petroleum-based polyether polyols. However, polyurethane made of petroleum-based polyether polyols has high stability and is difficult to decompose in a natural state; making them non-degradable is not conducive to environmental protection and sustainable development. With the expansion of the application field of sponge products, the market needs a large supply of sponges, because the current sponges have many performance defects

Abstract

The invention discloses a high-resistance polyurethane sponge and a preparation method, and the sponge comprises the following raw materials by weight: 110-120 parts of methoxy polyethylene glycol, 50-60 parts of isophorone diisocyanate, 15-20 parts of polyurethane resin, 20-25 parts of dichloromethane, 0.35-0.50 parts of dibutyltin dilaurate, 0.7-0.8 parts of N,N-Dimethyl cyclohexyl amine, 4.0-5.5 parts of tung oil, 0.3-0.4 parts of antioxidant 168, 0.5-1.0 part of anti-ultraviolet agent, 5.5-7.5 parts of iso-tridecanol polyoxyethylene ether, 3-4 parts of modifier and 10-11 parts of water. The high-resistance polyurethane sponge has excellent oxidation resistance, light resistance and aging resistance, zirconium tetrafluoride has the characteristics of high tensile strength, good thermostability and strong corrosion resistance, polyurethane resin is a high polymer material with high strength, tear resistance and wear resistance, and the high resistance of the sponge can be greatly increased.
