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 resilience of the material become worse, the anti-skid performance is poor, and the texture of rubber is lacking

Abstract

The invention relates to a composite material, in particular to a polymer rubber composite material specially applied to assemblies such as shoe materials, sports goods and leather. The polymer rubber composite material is mainly prepared from a colloidal particle raw material, a filling agent, a coupling agent, a metal oxide, a lubricating agent, a foaming agent and a bridging agent which are mixed according to a certain proportion, wherein the colloidal particle raw material is prepared from mixing EVA (ethylene vinyl acetate) and POE (polyolefin elastomer) with modified ethylene propylene diene monomer and chlorinated polyethylene rubber. The modified ethylene propylene diene monomer and the chlorinated polyethylene rubber are introduced in a formula, meanwhile, the coupling agent is introduced in the formula for improving compatibility and bonding property of all component materials and improving strength and anti-abrasion property of the composite material, and therefore the resilience, the flexibility and the abrasive resistance of the polymer rubber composite material are greatly improved, and the texture and the anti-slip property of the polymer rubber composite material can reach the grade of a rubber material.

Description

technical field [0001] The invention relates to a composite material, especially a foam rubber 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 el...
