Abstract

The invention relates to a low-density composite material for rapid demoulding shoes and belongs to the technical field of polyurethane synthesis. The low-density composite material is prepared from a component A and a component B, wherein the component A is prepared from the following raw materials in parts by weight: 100 parts of polyester polyol, 3 to 7 parts of a chain extender, 0.5 to 1 part of a crosslinking agent, 0.4 to 0.8 part of a foam stabilizer, 0.3 to 0.7 part of a foaming agent, 0.3 to 0.8 part of a mildew-proof aid and 1 to 2 parts of an amine catalyst; the component B is prepared from the following raw materials in parts by weight: 30 to 40 parts of polyether polyol and / or polyester polyol, 60 to 70 parts of isocyanate and 10 to 30 ppm of a storage stabilizer. Excellent performance of polyester and low-temperature flexibility and hydrolysis resistance of polyether are combined, so more comfortable elasticity and more durable service life are given to shoe pads and insoles; the mildew-proof aid is added, a convenient storage mode is given to the shoe pads and the insoles and the low-density composite material is more suitable for hostile environment and weather.

Description

technical field

[0001] The invention relates to a low-density composite material for fast demoulding shoes, which belongs to the technical field of polyurethane synthesis. Background technique

[0002] Polyurethane products have the advantages of good wear resistance, high strength, and excellent elasticity. At the same time, they can be made into products with different densities and hardnesses, which greatly meet the individual needs of the market. They are widely used in shoe soles, midsoles, and insoles. .

[0003] With the increase of people's requirements for the comfort of shoes, the requirements for insoles and midsoles are also getting higher and higher: light weight, good dimensional stability, high strength, good cushioning, sweat absorption, deodorization, mildew resistance, etc., the existing The polyester product has good wear resistance and tear resistance, and the polyether type has the characteristics of hydrolysis resistance and low temperature flexibility...
