METHOD FOR PREPARING MODIFIED WATER-BASED POLYURETHANE INSOLE
Document Type and Number:
WIPO Patent Application WO/2020/098039
Kind Code:
A1
Abstract:
A method for preparing a modified water-based polyurethane insole, comprising the following steps: stirring to mix a water-based polyurethane prepolymer emulsion, a rubber emulsion, a foaming agent, a foam stabilizer, a catalyst and a hardener to form modified water-based polyurethane; injecting the modified water-based polyurethane into an insole mold and heating for foaming formation; extracting the insole formed by foaming from the mold, and cutting off residual corners on the insole. By producing insoles by using the method for preparing a modified water-based polyurethane insole, the production process for insoles is simplified such that the production of insoles is faster, manpower and resources are saved, and production costs are reduced.
