Abstract

The invention relates to a wear-resistant EVA (Ethylene-Vinyl-Acetate) sole material. The wear-resistant EVA sole material comprises the following materials in percent by weight: 65%-85% of an ethylene-vinyl-acetate copolymer, 5%-10% of a wear-resistant agent, 0.5%-5% of a light stabilizer, 5%-20% of inorganic filler with the particle diameter being less than or equal to 200nm, 1%-3% of a foaming agent, 0.5%-2% of a cross-linking agent and 1%-3% of a dispersive lubricating agent. Compared with the prior art, the wear-resistant EVA sole material has the advantage of being excellent in wear resistance, and is prepared by selecting an ultrahigh-molecular-weight organic silicon wear-resistant agent with proper molecular weight.

Description

technical field [0001] The invention relates to the technical field of polymer composite materials, in particular to a wear-resistant EVA sole material composition. Background technique [0002] Ethylene-vinyl acetate copolymer (EVA) has good plasticity, elasticity and processability, and the foamed material has the advantages of low density, good mechanical properties, and easy coloring. It is widely used in shoe sole materials, but EVA materials It has the disadvantage that its wear resistance is not as good as that of rubber shoe materials, thus limiting its partial application. Contents of the invention [0003] The purpose of the present invention is to provide a kind of EVA shoe sole material with excellent wear resistance. [0004] The purpose of the present invention can be achieved through the following technical solutions: a wear-resistant EVA shoe sole material is made up of the following mass fraction components: [0005] Ethylene-vinyl acetate copolymer 65%~...
