Problems solved by technology

The materials used above are either too heavy, such as metal springs, or because of the unsaturated bonds in the materials, the UV aging resistance and wear resistance are poor. At the same time, they are combined with other materials such as EVA foam composite materials. During vulcanization molding, it cannot be synchronized, resulting in delamination and cannot be bonded, and its application range is limited

Abstract

The invention relates a composite material, in particular to a rubber-plastic composite material especially used as shoe material and for components such as sporting goods, leather and the like. The composite material is obtained by proportionally mixing rubber-plastic composite particles, a filling agent, a blowing agent, a blowing promoter, a lubricating agent and a cross-linking agent, and the rubber-plastic composite particles are obtained by proportionally mixing hydrogenated styrene-butadiene copolymer, ethylene-octene copolymer and chlorinated polyethylene. The shock-absorbing rubber-plastic composite material provided by the invention has an excellent anti-ultraviolet performance, good wear-resisting and scratch resisting performances and low rebound resilience, and meanwhile is convenient for direct vulcanization shaping with EVA (ethylene-vinyl acetate copolymer) composite materials for bonding.

Description

【Technical field】 [0001] The invention relates to a composite material, especially a rubber-plastic composite material specially used for shoe materials, sporting goods, protective articles and other products. 【Background technique】 [0002] At present, the use of shock-absorbing buffer materials is more commonly the following: (1) utilize metal or plastic devices to absorb shock, such as installing spring columns on the heels of various sports shoes or placing air bags in the shoes to achieve shock absorption Cushioning effect; (2) Using foam material as shock absorbing material, mainly composed of brominated butyl rubber, hydrogenated isoprene-hydrogenated styrene, and isoprene-styrene as the main raw materials . The materials used above are either too heavy, such as metal springs, or because of the unsaturated bonds in the materials, the UV aging resistance and wear resistance are poor. At the same time, they are combined with other materials such as EVA foam composite m...
