Problems solved by technology

The existing EVA composition modified by POE (polyethylene hydrocarbon elastomer) is light in weight and easy to shape, but the softness and elasticity of the material are not good, and even if the softness partially meets the requirements, its strength is still poor , especially the wear resistance is not ideal, and when the wear resistance is improved, the flexibility and rebound performance of the material become worse

Abstract

The invention discloses a composite material, in particular to a rubber plastic composite material for shoes, sports goods and leather components. The composite material is prepared by mixing rubber particle raw material, a filler, a coupling agent, metal oxide, a lubricant, a foaming agent and a cross linking agent with a certain proportion. The rubber particle raw material is obtained by mixing EVA (ethylene vinyl acetate), POE (polyolefin elastomer), modified ethylene propylene diene monomer, and oil-extended (mineral oil) styrene-ethylene / butylene-styrene copolymer. By introducing the modified ethylene propylene diene monomer and oil-extended (mineral oil) styrene-ethylene / butylene-styrene copolymer to the formula, the resilience and toughness of the composite material are greatly improved, at the same time, by introducing the coupling agent to the formula, the compatibility and consistency of components in the composite material are improved, and the strength and wear resistance of the composite material are increased.

Description

technical field [0001] The invention relates to a composite material, especially a 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% talcum powder or CaCO3, metal oxide 1-2%, lubricant 0.1-1%, peroxide (bridging agent) 0.4-1%, even Nitrogen foaming agent 1-4% and appropriate amount of pigment are mixed by internal mixer, auxiliary mixing by open mixer, 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 the softness and elasticity of...
