Abstract

The invention provides an environmental-friendly foamed insole material, and a preparation method thereof. The environmental-friendly foamed insole material is prepared from an EVA composite materialthrough foaming; the EVA composite material comprises, by weight, 30 to 40 parts of ethylene-vinyl acetate copolymer, 10 to 35 parts of biological Ethylene-Propylene-Diene Monomer, 10 to 20 parts of adegradable resin, 0 to 20 parts of polyolefin elastomer, 10 to 20 parts of plant fiber powder, 0.5 to 0.8 part of a cross-linking agent, 2.5 to 3 parts of a foaming agent, and 2.5 to 3.5 parts of anactivator. The degradable resin is one or a mixture of a plurality of components selected from poly (butyleneadipate-co-terephthalate and polylactic acid. The environmental-friendly foamed insole material is degradable, is high in biomass content, is excellent in performance. The preparation method is capable of recycling waste resource, and reducing using of non-renewable petroleum resources; thedegradable part is capable of reducing carbon dioxide emission; and energy saving and carbon emission environmental protection effect is achieved.

Description

technical field

[0001] The invention relates to the technical field of footwear product materials, in particular to an environmentally friendly foam midsole material and a preparation method thereof. Background technique

[0002] Sports shoe soles usually consist of outsoles and midsoles. The outsole refers to the layer structure that is in direct contact with the ground. It is usually made of natural rubber or artificial rubber and has the functions of anti-slip, wear-resistant and bending-resistant. The midsole generally refers to the structure between the insole and the outsole, which mainly plays the role of support or rebound. At present, the soles of sports shoes are basically foamed from petrochemical products, such as ethylene vinyl acetate copolymer (EVA), polyolefin elastomer (POE), ethylene propylene diene monomer (EPDM), ethylene octene block copolymer (OBC), styrene-based block copolymer (SEBS), polyethylene (PE), butadiene rubber (BR), styrene-butadiene rubber...
