Abstract

The invention describes a preparation method of a simulated wood anti-sulfuration material for polyether polyurethane shoes. The simulated wood anti-sulfuration material is prepared by a chemical reaction of component A and component B . The component A is a mixture of polyether polyol A (functionality f equals 3, and OH equals 26-28mgKoH / g), polyether polyol B (functionality f equals 2, and OH equals 26-28mgKoH / g), polyether polyol C (GR-4110), a polyurethane crosslinking agent, a foam stabilizer, a foaming agent, a catalyst and the like; and the component B is a prepolymer of the polyether polyol B (functionality f equals 2, and OH equals 26-28mgKoH / g), 4,4-diphenyl diisocyanate (MDI) and polyphenylpolymethylene isocyanate (raw MDI).

Description

Background technique

[0001] Polyurethane material is a synthetic polymer material with a wide range of uses and excellent performance. After World War II, the research and application of polyurethane materials developed worldwide. Polyurethane materials have the characteristics of wear resistance, tear resistance, good flexural resistance, and excellent processing performance. They are widely used in transportation, home appliances, shoemaking, machinery, construction, textiles, sports equipment, and national defense. Although polyurethane materials have the above-mentioned excellent properties, they also have poor thermal stability, low density and low hardness, which restrict the application of polyurethane materials in certain fields. Compared with ordinary polyurethane materials, polyether polyurethane imitation wood vulcanization-resistant materials have the characteristics of low density, high hardness and good thermal stability. In recent years, they have been widely u...
