Abstract

The invention discloses a high-resilience wear-resistant EVA composite foam material, a preparation method and a composition for preparing the material. The composition comprises the ingredients in parts by mass: 30-50 parts of ethylene-vinyl acetate copolymer, 10-20 parts of polyolefin thermoplastic elastomer, 10-20 parts of polyolefin block copolymer, 4-10 parts of thermoplastic polyurethane, 5-10 parts of thermoplastic polyester elastomer, 5-10 parts of anti-wear agent, 0.5-1 part of zinc oxide, 0.5-1.5 parts of zinc stearate, 0.5-1.2 parts of cross-linker, 0.1-0.3 part of crosslinking assistant and 1.5-3.5 parts of foamer. The preparation method comprises the steps of feed weighing, reblending, granulating and foaming. The obtained high-resilience wear-resistant EVA composite foam material is high in resilience and excellent in wear resistance and is applied to production of shoe soles of sports shoes.

Description

technical field

[0001] The invention relates to the field of rubber-plastic composite materials, in particular to a high-elastic and wear-resistant EVA composite foam material, a preparation method and a composition for preparing the material. Background technique

[0002] As the main component of sports shoes, the sole affects the wearer's experience. The demand for lightweight and high-elastic sports shoes has attracted more and more attention from consumers. At the same time, reducing the links in the manufacturing process and reducing production costs are also the direction of efforts of sports shoe manufacturers. The use of high-elastic and wear-resistant EVA foam material to replace part of the rubber directly as the outsole of sports shoes can effectively solve the above problems. However, in order to meet certain wear-resisting requirements, the current EVA foam materials for shoe soles generally have higher hardness, higher density, and poor performances such as ma...
