Problems solved by technology

However, although rubber soles have good wear resistance and anti-skid properties, due to the addition of a large amount of reinforcing agents and fillers, the rubber density is too large, and the soles are heavy to wear; in addition, the elasticity of rubber soles is not very good. And it is easy to age, making the shoes harder and harder to wear, and the foot feel is poor

Abstract

The invention discloses a polybutadiene-based rubber for a non-slip wear-resistant shoe sole and a preparation method of the polybutadiene-based rubber for the non-slip wear-resistant shoe sole. Comprising the following components in parts by weight: 60 parts of polybutadiene rubber, 32 to 48 parts of thermoplastic elastomer SBS, 26 to 35 parts of modified szaibelyite composite particles, 1.5 to 3.6 parts of terpene-phenolic resin, 0.2 to 0.8 part of a silane coupling agent, 1.2 to 1.8 parts of an anti-aging agent, 2.3 to 4.6 parts of sulfur and 1.1 to 1.6 parts of an accelerant. The anti-slip wear-resistant sole rubber based on polybutadiene prepared by the invention not only has wear resistance and skid resistance, but also has the advantages of light weight and strong elasticity, and in addition, the ageing resistance is also well improved.

Description

technical field [0001] The invention relates to the field of rubber elastomers, in particular to a polybutadiene-based anti-slip and wear-resistant rubber for soles and a preparation method thereof. Background technique [0002] The sole material is an important part of the shoe. The quality of the sole material not only determines the performance of a pair of shoes, but also affects the comfort of the wearer. With the improvement of living standards and fitness awareness, people pay more and more attention to the performance requirements of sole materials, which not only require the soles to be non-slip and wear-resistant, but also have various additional functions such as light weight, softness and comfort, or are suitable for specific purposes. Rubber has become the sole material of most shoes due to its relatively good wear resistance. However, although the rubber sole has good wear resistance and anti-skid performance, due to the addition of a large amount of reinforci...
