Abstract

The invention relates to a preparation process of a high-wear-resistance soft rubber and plastic ejection foam material. The foam material is prepared from the following raw materials in parts b weight: 45-48 parts of an ethylene-vinyl acetate copolymer of which the VA content is 22% to 28%, 20-24 parts of an ethylene-vinyl acetate copolymer of which the VA content is 36% to 40%, 10-15 parts of an ethylene-octylene copolymer, 13-15 parts of ethylene-propylene-diene monomer rubber, 12-15 parts of SEBS, 10-13 parts of a wear resisting agent, 0.8-1.0 part of a bridging agent and 2.1-2.4 parts of a foaming agent. The raw materials are sequentially treated by an internal mixer, a granulator and an injector to obtain the foam material. The foam material prepared by the preparation process disclosed by the invention is relatively good in softness, rubber touch feeling and high-elasticity physical properties; the foam material disclosed by the invention can be used for improving the rubber and plastic texture and elasticity of an EVA foamed product, is applicable to casual living shoe products for unprofessional sports, can be used for improving the wearing comfort of products and can satisfy the requirements of urban people on casual living.

Description

Technical field [0001] The invention relates to a foaming material, in particular to a manufacturing process of a soft and high wear-resistant rubber-plastic injection foaming material. Background technique [0002] The EVA foam material commonly used in the market for sports soles needs to meet the needs of professional sports. Generally, the hardness setting will be higher, resulting in poor foot feeling, making people feel less shock absorption and comfort during normal walking, and cannot meet modern cities. The crowd pursues comfortable and leisure life needs. Summary of the invention [0003] The present invention provides a manufacturing process of soft and high wear-resistant rubber-plastic injection foaming material, so as to overcome the problem of high hardness of foamed materials prepared in the prior art. [0004] The present invention adopts the following technical solutions: [0005] The manufacturing process of soft and high wear-resistant rubber-plastic injection fo...
