Shoe sole rubber composition

Abstract

The invention discloses a rubber composition. The rubber composition comprises the following components in parts by weight: 5-10 parts of fluorosilicone rubber, 10-20 parts of acrylonitrile-butadiene rubber, 15-30 parts of styrene-butadiene rubber, 10-20 parts of isoprene rubber, 10-20 parts of white carbon black, 2-5 parts of calcium sulfate, 5-10 parts of stearic acid, 1-3 parts of sulfur, 1-3 parts of a vulcanization accelerator, 2-3 parts of zinc oxide and 1-2 parts of an anti-aging agent. Shoe soles prepared form the shoe sole rubber composition provided by the invention have abrasion resistance and good elasticity.

Description

technical field [0001] The invention relates to a rubber composition, in particular to a rubber composition used for shoe soles. Background technique [0002] The sole is an important part of the shoe material field. The main function of the sole is to protect the feet, prevent slipping, shock absorption, ensure the comfort of the wearer's feet, and reduce the chance of sports injuries. The material of the sole is mostly rubber sole, such as ordinary rubber sole, thermoplastic molding, divided into natural rubber and recycled rubber. [0003] Rubber soles are required to have the characteristics of good wear resistance, non-slip, elasticity, not easy to break, good softness, good extensibility, stable shrinkage, good hardness, good bendability, waterproof and good elasticity. [0004] Known various footwear made with the rubber soles made by the general vulcanization molding process, because the soles lack elasticity and are heavy, they feel uncomfortable when worn.

Problems solved by technology

[0007] But the elasticity of the rubber sole of the prior art still can not satisfy the demand of footwear especially sports footwear, therefore this field needs to provide a kind of wear resistance good, the rubber composition that elastic good is used for sole
