Title:
SUPER-IMPACT ABSORPTION HIGH-RESILIENCE FOAMING MATERIAL, AND PREPARATION METHOD THEREFOR AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/015693
Kind Code:
A1
Abstract:
The present invention provides a super-impact absorption high-resilience foaming material, which is formed by a foaming composition: the foaming composition comprises: 10-35 parts by weight of a copolymer of an isoolefin and a straight-chain end olefin; 40-60 parts by weight of an ethylene-vinyl acetate copolymer; 5-20 parts by weight of a polyolefin elastomer; 5-10 parts by weight of ethylene propylene diene monomer rubber; 5-15 parts by weight of a styrenic polymer; 0.1-1 part by weight of a peroxide crosslinking agent; 1-5 parts by weight of a foaming agent; and 1-5 parts by weight of a foaming aid. The number of carbon atoms of the isoolefin is 5-8, and the number of carbon atoms of the straight-chain end olefin is 2-4. Compared with the prior art, the present invention relates to performing blending and foaming on a copolymer of a stress-absorbing polymer isoolefin having large steric hindrance and a straight-chain end olefin and a high-resilience polymer to obtain a foaming material, which not only has excellent stress absorption, stress relaxation, damping and shock absorption effects at room temperature, but also maintains a rebound rate greater than 50%.
