Abstract

The invention relates to a high-softness high-wear-resistance rubber-plastic injection foam material which is prepared from the following raw materials in percentage by weight: 45-48% of ethylene-vinyl acetate (EVA) copolymer with the VA (vinyl acetate) content of 22-28%, 20-24% of EVA copolymer with the VA content of 36-40%, 10-15% of ethylene-octylene copolymer, 13-15% of ethylene propylene diene monomer rubber, 12-15% of styrene-ethylene-butadiene-styrene (SEBS), 10-13% of anti-wear agent, 0.8-1.0% of bridging agent and 2.1-2.4% of foaming agent. The foam material has the advantages of high softness, rubber feeling, high elasticity and favorable physical properties, can improve the plastic feeling and elasticity of the EVA foam product, is suitable for casual living shoes for nonprofessional sports, enhances the wear comfort of the product, and satisfies the demands for casual living of urban people.

Description

technical field [0001] The invention relates to a foaming material, in particular to a soft and highly wear-resistant rubber-plastic injection foaming material. Background technique [0002] The commonly used EVA foam material for sports shoes on the market needs to meet the needs of professional sports. Generally, the hardness setting will be too high, resulting in poor foot feel, making people feel no obvious shock absorption and comfort when walking normally, and cannot meet the needs of modern cities. The crowd pursues the needs of a comfortable and leisure life. Contents of the invention [0003] The invention provides a soft and highly wear-resistant rubber-plastic injection foaming material to overcome the problem of relatively high hardness of the existing foaming materials. [0004] The present invention adopts following technical scheme: [0005] Soft and highly wear-resistant rubber and plastic injection foaming material, the raw materials of the foaming mater...
