Abstract

The invention discloses polyurethane resin used for a breathable insole as well as a preparation method and application. The resin comprises a resin A component, a resin B1 component and a resin B2 component, wherein the resin A component comprises polyalcohol A, a cross-linking agent, a catalyst, a foaming agent and a foam stabilizer; the resin B1 component comprises the following ingredients in parts by weight: 80-100 parts of isocyanate B1, 1-30 parts of polyalcohol B1 and 0.002-0.010 parts of a side-reaction inhibitor; the resin B2 component comprises the following ingredients in parts by weight: 100 parts of isocyanate B2, 50-100 parts of polyalcohol B2 and 0.002-0.010 parts of a side-reaction inhibitor; the isocyanate B1 is diphenyl methane diisocyanate, carbodiimide modified diphenyl methane diisocyanate, toluene diisocynate or naphthalene diisocyanate; the polyalcohol B1 is polyoxyethylene-propylene oxide trihydric alcohol; the isocyanate B2 is diphenyl methane diisocyanate, carbodiimide modified diphenyl methane diisocyanate, toluene diisocynate or naphthalene diisocyanate; the polyalcohol B2 is polyoxyethylene-propylene oxide dihydric alcohol. According to the polyurethane resin disclosed by the invention, breathable insoles with different hardness can be prepared, and the cost is low.

Description

technical field [0001] The invention relates to a polyurethane resin for insoles, 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 insole has the characteristics of light weight, good elasticity, high strength, wide adjustable range of hardness, etc. It is suitable for the requirements of different shoe types of different manufacturers. [0003] The resin used to produce polyurethane insoles is generally a two-component raw material - polyol mixture and prepolymer (referred to as AB material / AB component or black and white material). [0004] Polyurethane insoles with different hardness and different performance requirements need to be used with different types of AB materi...
