Abstract

The microporous polyurethane elastomer composition material suitable for insole consists of one component A and one component B in the weight ratio of 100 to 60-80. The component A consists of polyether polyol, polymer polyol, cross-linking agent, foam stabilizer, foaming agent and catalyst; and the component B is pre-polymer of polyether polyol and isocyanate. When it is used, the two components are mixed in the said weight ratio at normal temperature to form microporous polyurethane elastomer. The normal temperature production process of insole is simple and has easy operation, no waste, stable product quality and low production cost.

Description

technical field [0001] The invention belongs to a polyurethane microporous elastomer composite material, in particular to a polyurethane microporous elastomer composite material suitable for insoles and a preparation method thereof. Background technique [0002] At present, the shoe industry has become an important market for polyurethane products. China has a large population, and polyurethane raw materials for shoes have great potential for development. In recent years, many manufacturers of high-end sports shoes have produced the insole (also known as the inner bottom) as an independent unit, and the molding density of the insole is required to be 0.2-0.3g / cm 3 , and requires stable dimensions, high strength, good surface crust, and no defects. Now on the market, most of the insoles are polyester type, and a small amount of ordinary high-activity polyether type is used. Some properties of polyester insoles, such as abrasion resistance and tear resistance, are superior ...
