Abstract

The invention provides a production method of a polyurethane composite for shoe materials. The production method generally includes the steps: (1) hydrolyzing ethyltrichlorosilane prior to reacting with potassium hydroxide serving as a catalyst to obtain POSS (polysilsesquioxane); (2) subjecting the POSS, propylene oxide, dipropylene glycol, dibromo butyl diol and carbon dioxide to reaction through a DMC catalyst so as to obtain PPC (polypropylene carbonate); (3) uniformly mixing the PPC, a surfactant, a catalyst, an opening agent, a chain extender and a forming agent to prepare a mixture; (4) mixing isocyanate with the mixture prior to casting, demoulding and curing so as to obtain the polyurethane composite for the shoe materials. The polyurethane composite prepared through the method has good flame retardancy and heat resistance.

Description

Technical field: [0001] The invention relates to a composite material, in particular to a method for manufacturing a polyurethane composite material used for shoe materials. Background technique: [0002] Polyurethane is the abbreviation of polyurethane, the English name is polyurethane, and it is a new organic polymer material, known as the "fifth largest plastic". [0003] Products made of polyurethane resin come in various forms, including foam plastics, elastomers, coatings, adhesives, fibers, synthetic leather, pavement materials, etc., and are widely used in electromechanical, ships, aviation, vehicles, civil engineering, light industry, and textiles, etc. One of the most widely used polyurethane elastomers. [0004] Polyurethane elastomer has the characteristics of good cushioning performance, light weight, wear resistance, anti-skid, etc., and has good processing performance. It has become an important synthetic material for shoes in the shoe industry. Functional s...
