[0005] Chinese invention patent CN201110044932.2 discloses a kind of EVA material for sports shoe soles and a preparation method thereof. The EVA foam material is blended and modified by starch / ethylene-vinyl acetate copolymer / ethylene-a-olefin copolymer. Starch is used in chemical plastics to reduce the consumption of chemical raw materials. At the same time, because starch derivatives possess the characteristics of natural degradation, the easy degradation performance of the EVA foam material of the present invention is improved, but the wear resistance of the material is relatively poor. And the rebound rate does not exceed 48%
Chinese invention patent CN201010248174.1 discloses a high-shock-absorbing, wear-resistant sports shoe sole material and its manufacturing method. On the basis of rubber, softening oil and reinforcing It is prepared through the screening of active agents and reasonable control of the process. It has excellent shock absorption, wear resistance, and wet skid resistance, but its density is relatively high, its rebound rate is average, and it is not easy to degrade, which does not meet modern standards.

Abstract

The invention discloses a light high-wear-resistance sports shoe sole material and a preparation method thereof, and relates to the technical field of sports shoes. The invention discloses a light high-wear-resistance sports shoe sole material, which is prepared by the following steps: carrying out graft crosslinking on polylactic acid and polyisobutene under the action of a crosslinking agent andan active agent to generate a PLS/PIB blend, and carrying out mold pressing foaming on the PLS/PIB blend, C5/C9 copolymer resin, a polyether thermoplastic polyurethane elastomer, waste rubber powderand other raw materials. According to the sports shoe sole material, the raw materials are environmentally friendly, the preparation process is simple and easy to operate, the density is low, the elasticity is high, the sports shoe sole material has excellent impact resistance, abrasion resistance, weather resistance, corrosion resistance and wet skid resistance, meanwhile, the degradation performance of the material is improved, and pollution to the environment is reduced.

Description

technical field [0001] The invention belongs to the technical field of sports shoes, and in particular relates to a sports shoe sole material with light weight and high wear resistance and a preparation method thereof. Background technique [0002] With the rapid development of modern society, people's concept of wearing shoes has undergone great changes, from protection and heat preservation in the last century to the pursuit of lightness, comfort, beauty, shock absorption, wear resistance and other functions now. As the largest country in the world in the production and consumption of sports shoes, our country is also changing with each passing day to the research and development of sports shoes. Existing sports shoe soles are divided into three categories: vulcanized rubber bottoms, air-cushion filled bottoms and foam bottoms. With the continuous development of science and technology, foam bottoms occupy a relatively large area of ​​sports shoe soles because of their exce...
