Problems solved by technology

[0007] The present invention adopts a two-step mixing method. First, the EVA elastomer system and the oil-resistant rubber system are mixed separately, and then the two are mixed. The two-step mixing method can effectively improve the processing of fillers and additives that are difficult to disperse in the one-step mixing method. difficult problem; secondly, by adding a small amount of nano fillers, the present invention not only makes the shoe material wear-resistant, oil-resistant, and antistatic, but also effectively improves the tear resistance.

Description

technical field [0001] The invention relates to an elastomer engineering shoe sole material and a preparation method thereof, in particular to an engineering shoe sole material with excellent wear resistance and oil resistance, good antistatic performance and mechanical properties and a preparation method thereof. Background technique [0002] Traditional sole materials usually adopt rubber (elastomer), which has the advantages of light weight, good elasticity, non-slip, waterproof, and shock absorption. Ethylene-vinyl acetate copolymer (EVA) is an elastomer material widely used in the field of shoe materials. According to the content of vinyl acetate monomer (VA), it can be made into sports shoe soles for different purposes, but EVA soles are wear-resistant , poor oil resistance, which restricts the development of EVA soles in the field of engineering shoe materials that need wear-resistant and oil-resistant working environments such as oil fields, chemicals, construction, ...
