Polyurethane foaming sole and production method thereof

Abstract

The invention discloses a polyurethane foaming sole and a production method thereof. The polyurethane foaming sole is prepared form foaming liquid and graphene, wherein the foaming liquid is preparedfrom the following components in parts by weight: 18 to 36 parts of polyester polyol, 20 to 40 parts of isocyanate, 0 to 1.5 parts of hardening agent, 0.3 to 0.4 part of catalyst and 0.1 to 0.13 partof water; the weight of the graphene accounts for at least 1 percent of the weight of the foaming liquid at least. All components in raw materials are mixed and then are injected into a mold and are heated and foamed; after a mixture is cooled and molded, a sole finished product is obtained. The polyurethane foaming sole provided by the invention has the advantages of easiness for obtaining the raw materials, simple production technology, easiness for operation, capability of realizing batch production and high economic benefits; the sold is integrally molded and does not need to be adhered byglue so that the sole is economical and environmentally friendly; the adjusting range of thickness and hardness is large and the variety of products is more, so that the sole is adaptive to market requirements; the graphene is added so that the bending resistance and the wear resistance of the product are improved; the polyurethane foaming sole is suitable for producing shoe pads; the heat dissipation efficiency of the shoe pads is improved through the graphene and people feel cool and comfortable when wearing the shoe pads.

Description

technical field [0001] The invention relates to the technical field of polyurethane foamed shoe soles, in particular to a polyurethane foamed shoe sole and a manufacturing method thereof. Background technique [0002] The sole made of polyurethane has the characteristics of good elasticity, comfortable and light wearing, so polyurethane is mostly used to make leather shoes, sports shoes and travel shoes. However, the soles made of polyurethane foam on the market have complex components, add various additives, and have high production costs. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the invention provides a polyurethane foam sole and a manufacturing method thereof. [0004] A polyurethane foam sole disclosed by the invention comprises foaming liquid and graphene, and the foaming liquid includes 18-36 parts of polyester polyol, 20-40 parts of isocyanate, 0-1.5 parts of hardener, 0.3-0.4 parts of Catalyst and 0.1-0.13 parts of water, th...
