Abstract

The invention relates to a composite material, in particular to a rubber and plastic composite material which is specially used for the components of shoe materials, sports goods, leather and the like. The composite material is mainly prepared by mixing a colloidal particle raw material, a bulking agent, a coupling agent, metal oxides, a lubricating agent, a foaming agent and a bridging agent according to a certain ratio, wherein the colloidal particle raw material is prepared by mixing EVA (Ethylene Vinyl Acetate), POE (Polyolefin Elastomer) and ethylene propylene rubber. The composite material provided by the invention improves the compatibility and associativity of each component material by adding the ethylene propylene rubber and the coupling agent into the formula so as to enhance the strength and abrasion resistance of the rubber and plastic blended material, thus the obtained rubber and plastic composite material maintains the plasticity of the EVA material and has the advantages of flexibility, elasticity, skid resistance and excellent abrasion resistance of a rubber material.

Description

【Technical field】 [0001] The invention relates to a composite material, especially a rubber-plastic composite material specially used for shoe materials, sporting goods, leather and other components. 【Background technique】 [0002] Most of the existing EVA adopts the production method of POE modified materials. The modified materials are suitable for injection molding and compression molding. They can be widely used in shoe outsoles, sporting goods and other light industrial products. The ingredients are composed of 50-95% EVA, 5 -40% POE (Polyolefin Elastomer), 5-20% Talc or CaCO 3 , 1-2% of metal oxides, 0.1-1% of lubricants, 0.4-1% of peroxides (bridging agents), 1-4% of azo foaming agents and appropriate amount of pigments are mixed by internal mixer, and the kneading Machine-assisted mixing, pelletizing, injection molding or compression molding. The existing EVA composition modified by POE (polyethylene hydrocarbon elastomer) is light in weight and easy to shape, but ...
