Abstract

The invention provides an anti-deformation and high-supporting EVA (Ethylene Vinyl Acetate) foaming material as well as a preparation method and application thereof. The foaming material is prepared by foaming an EVA composite material; the EVA composite material is prepared from the following components in parts by weight: 40 to 50 parts of an ethylene vinyl acetate copolymer, 0.5 to 50 parts ofa block copolymer, 0 to 30 parts of a polyolefin elastomer, 0.5 to 15 parts of aramid fiber, 0.5 to 1 part of a crosslinking agent, 2.5 to 3 parts of a foaming agent, 1 to 2 parts of a coupling agentand 2 to 3 parts of an active agent; the block copolymer is one or more of an ethylene-octene block copolymer and a styrene series block copolymer; the mass content of a hard section in the block copolymer is 30 to 45 percent. The EVA foaming material provided by the invention has good softness and comfort, high supporting performance and high stability, and meets higher exercise requirements whenconsumers wear sports shoes.

Description

technical field

[0001] The invention relates to the technical field of footwear product materials, in particular to a deformation-resistant high-support EVA foam material and a preparation method and application 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 midsole is mainly made of thermoplastic elastomer materials such as ethylene vinyl acetate copolymer (EVA), styrene-based thermoplastic elastomer (SBS), ethylene octene block copolymer (OBC), and thermoplastic polyurethane (TPU). foam structure.

[0003] As we all know, as the intensity of exercise increases,...
