Problems solved by technology

The existing EVA composition modified by POE (polyethylene hydrocarbon elastomer) has a certain degree of lightening and easy molding, but the softness and folding resistance of the material are not good, even if part of the softness meets the requirements Its strength is still poor, especially the wear resistance is not ideal, and when the wear resistance is improved, the flexibility of the material becomes worse, and the anti-skid performance is poor

Abstract

The invention relates to the field of shoe material manufacturing, and provides ultralight rubber foam colloid particles. The ultralight rubber foam colloid particles are prepared from, by weight, 20-40 parts of CPE-CM (chlorinated polyethylene), 12-18 parts of POE (polyolefin elastomers), 6.4-9.6 parts of EPDM (ethylene-propylene-diene monomer), 9.6-14.4 parts of EVA (ethylene vinyl acetate), 8-12 parts of natural rubber or isoprene rubber, 5.6-8.4 parts of filler, 0.24-0.36 part of stearic acid, 0.48-0.72 part of zinc stearate, 0.48-0.72 part of a DCP cross-linking agent, 0.64-0.96 part of zinc oxide, 0.96-1.44 parts of an AC foaming agent and 1.6-2.4 parts of a wear-resistant agent. Accordingly, the problems that an existing shoe material is poor in flexibility, fold resistance, anti-skid property and wear resistance, large in weight and like are solved.

Description

technical field [0001] The invention relates to the technical field of shoe material manufacturing, in particular to an ultra-light rubber foam granule and a preparation method thereof. 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%, 1-4% of azo foaming agent 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) has a certain degree of lightening and easy molding, but the softness and fold...
