Problems solved by technology

However, because the macromolecular chains of the filled EVA and POE thermoplastic elastomers are saturated structures, there are no double bonds that can undergo crosslinking reactions, and sulfur vulcanization cannot be used, so they cannot participate in the vulcanization process of traditional vulcanized rubber, resulting in thermoplastic elastomers and The compatibility of vulcanized rubber is poor, and the interfacial bonding is weak, which reduces the tear strength of the sole material to a certain extent

Abstract

The invention provides a light rubber material. According to a shoe sole made of the light rubber material, the tearing strength and the wear resistance of the shoe sole are not influenced on the premise that the shoe sole is light. Experiment results indicate that the specific gravity of the shoe sole made of the light rubber material is 0.93 plus / minus 0.02 g / cm<3> and is lower than that of a common rubber shoe sole, however, the hardness, the wear resistance, the fold resistance, the pulling force, the elongation rate and the right-angle tearing strength of the shoe sole are not reduced and basically the same as those of existing rubber shoe soles.

Description

technical field [0001] The invention relates to the technical field of rubber materials, in particular to a lightweight rubber material, a preparation method thereof and a shoe sole made of the material. Background technique [0002] With the improvement of living standards, people's requirements for shoes have been continuously improved, and have changed from simple functions such as cold protection and protection to fashion, lightness and comfort. The continuous emergence of new functional materials for shoes has provided many useful materials for the traditional shoemaking industry, not only triggering new fashion trends, but also providing a guarantee for the development of footwear functionality and comfort. [0003] Traditional vulcanized rubber soles have excellent tear strength, wear resistance, anti-slip and other properties, and are widely used in footwear products. However, traditional vulcanized rubber soles generally have the disadvantage of high specific gravi...
