Abstract

The invention discloses an anti-cracking rubber outsole, which is doped with a polyamide fiber material, and compared with the prior art, the anti-cracking rubber outsole provided by the invention has the advantages that the polyamide fiber is added in the internal mixing process of the rubber outsole, so that the polyamide fiber is high in strength, large in elongation, good in elasticity and excellent in wear resistance and heat resistance; the elasticity of the rubber outsole is greatly improved, the problem that the rubber outsole is bent many times in the long-term walking process, and the outsole is prone to cracking is solved, and the elasticity of the rubber outsole and the elasticity effect of the polyamide fiber are added, so that the shoe sole is more comfortable to wear.

Description

technical field [0001] The invention belongs to the field of shoemaking, and in particular relates to an anti-cracking rubber outsole. Background technique [0002] Shoes are the necessities of people's life, they can keep warm and protect the feet. However, the sole is very important for shoes. The structure of the sole is quite complicated. Materials generally have particularly high requirements on the outsole, because the outsole is often in contact with the ground and encounters the greatest friction, and the outsole is easily broken when it is bent many times during walking. As the main raw material of the footwear industry, rubber is widely used in the shoemaking industry. Compared with polyurethane, EVA and other materials, rubber is more balanced in terms of overall performance, but there are also characteristics that are not outstanding in various performance indicators, such as rubber Insufficient elasticity, the rubber outsole is bent many times during long-term ...
