Abstract

The invention relates to a sponge for shoes and a production method of the sponge. The sponge for shoes comprises the following raw materials: toluene diisocynate, polyether propylene glycol, polyether glycerol, triethylene diamine, triethylamine, a foaming agent, a foam stabilizer, a catalyst, clam meal, sepiolite powder and montmorillonite. The clam meal, the sepiolite powder and the montmorillonite are added as reinforcing agents, and are firstly stirred and mixed with polyether propylene glycol, polyether glycerol and toluene diisocynate, and then the clam meal, sepiolite powder and montmorillonite are packed into a matrix under the action of the foaming agent, so that a certain supporting effect is achieved on foam walls, foam is prevented from collapsing and shrinking, and the elasticity and toughness of the prepared sponge for the shoes are improved.

Description

technical field [0001] The invention belongs to the field of sponge production, and in particular relates to a shoe sponge and a production method thereof. Background technique [0002] Sponge is an elastic material made of foamed plastic polymers. Because sponge has the characteristics of heat preservation, heat insulation, sound absorption, shock absorption, flame retardancy, and good ventilation, it is involved in the shoe and clothing industry, automobile industry, battery industry, cosmetics, etc. Industry, household and many other industries. [0003] Shoes have a long history of development. Footwear production is an important industry in my country's light industry and an integral part of the clothing industry. There are many ways to classify shoes. According to different wearing objects, there are men's shoes, women's shoes, children's shoes, elderly shoes, etc.; according to the style, the head shape has square toe, round toe, pointed toe, etc., and the heel type ...
