Abstract

The invention relates to an anti-shrinkage shock-absorbing EVA foamed material. Raw materials in parts by mass are as follows: 40-80 parts of butadiene styrene rubber, 5-10 parts of EVA, 2-5 parts of azodiisobutyronitrile, 0.1-0.5 part of dibenzoyl peroxide, 0.2-0.7 part of titanium dioxide particles, 1-4 parts of dicumyl peroxide, 1-4 parts of talcum powder, 8-12 parts of polyacrylonitrile fibers, 0.8-2.1 part of an initiator and 1.3-1.8 parts of a catalyst. The anti-shrinkage shock-absorbing EVA foamed material provided by the invention is soft in texture and has better shrinkage resistance, fatigue resistance is improved, shock-absorbing performance is also better, and cost is lower.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to an anti-shrinkage and shock-absorbing EVA foam material. Background technique [0002] Ethylene-vinyl acetate copolymer, abbreviated as EVA in English, has been widely used in sports equipment, life-saving equipment, household products and other fields due to its excellent coloring performance and good flexibility since its inception. [0003] At present, a variety of plates based on EVA have been developed in China, and various additives are added, and then molded, cross-linked and foamed. The process is difficult to operate, and the product has poor aging resistance and flex resistance. The elasticity is poor and contains irritating smell, and the cost is high, so the performance needs to be further improved. Contents of the invention [0004] The technical problem to be solved by the invention is to provide an anti-shrinkage and shock-absorbing EVA foa...
