Abstract

The invention discloses a shoe sole made of a polyester based polyurethane material. The shoe sole comprises a component A and a component B, wherein the component A is prepared from the following components in parts by weight: 90-110 parts of polyester diol, 14-18 parts of butanediol, 0.2-0.6 part of water, 0.2-0.6 part of an emulsifier, 0.7-1.1 parts of a catalyst and 0.2-0.6 part of melanin; and the component B is prepared from the following components in parts by weight: 30-50 parts of polyester diol and 50-70 parts of dipropyl cyanate ester. According to the shoe sole, all components in the component A are physically mixed in a mixing container and are uniformly stirred, and the physical performances of the materials are not changed, so that the mechanical strength of the product is improved; contrary to the component A, the component B is a half-prefabricated polymer, each raw material performs effective chemical reactions in a vacuum or nitrogen filled reactor, and the reacted product has good heat resistance and solvent resistance.

Description

technical field [0001] The invention relates to the field of shoe sole materials, in particular to a shoe sole made of polyester polyurethane material. Background technique [0002] Sole materials can be roughly divided into two types: natural materials and synthetic materials. Most of the current mainstream research directions focus on synthetic materials, and synthetic materials can be subdivided into many types, such as rubber materials, EVA materials, resin materials, polyurethane materials, etc. , what the present invention specifically relates to is the sole that polyurethane material is prepared. [0003] Polyurethane material is comfortable to wear, has strong elasticity, and is easy to process and shape. It is widely used in the production of sports shoes and casual shoes. Corrosion resistance greatly restricts the further development of polyurethane materials. Contents of the invention [0004] Purpose of the invention: the purpose of the invention is to addres...
