Description

technical field [0001] The invention relates to a resin for polyurethane shoe soles, a preparation method and application. Background technique [0002] The full name of polyurethane is polyurethane, which is a general term for macromolecular compounds containing repeated urethane groups on the main chain. It is a polymer compound obtained by the interaction of binary or polyvalent organic isocyanates and polyol compounds. Polyurethane soles have the characteristics of light weight, good elasticity, high strength, oil resistance, wear resistance, and comfortable wearing, and are favored by more and more consumers. Polyurethane soles can be divided into polyether soles and polyester soles according to the different polyol raw materials used. Among them, polyether soles have better flexibility, strong hydrolysis resistance, and poor physical and mechanical properties; polyester soles have better physical and mechanical properties. Excellent mechanical properties, poor hydroly...
