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. The polyurethane sole has the characteristics of light weight and good resilience. [0003] The resin used to produce polyurethane soles is generally a two-component raw material - a polyol mixture and a prepolymer (referred to as AB material / AB component or black and white material). [0004] Polyurethane soles with different performance requirements need to be used with different types of AB materials. For polyurethane sole manufacturers, it is necessary to be equipped with various raw materials of different types and specifications to meet the product...
