Abstract

The present invention discloses a composite sole and a production method thereof. The composite sole is made by compositing an EVA (ethylene-vinyl acetate) injection molded midsole, a rubber outsole and an injection molded arch support sequentially; the EVA injection molded midsole is made with high-elasticity aging-resistant EVA foam material that is produced via the following steps of 1) modifying lignocellulose powder by using a silane coupling agent to obtain modified lignocellulose powder; 2) mixing partially hydrogenated styrene-butadiene polymer, ethylene-vinyl acetate copolymer and the modified lignocellulose powder for compounding; 3) adding a foaming agent, a bridging agent, an activating agent and zinc oxide into a mixing system for compounding; 4) granulating material that is compounded in steps 2) and 3), performing injection foaming, and cooling for molding. The composite sole has good elasticity, resilience, slip resistance and wear resistance, and meets the need for comfort to wear sports and leisure shoes and boots.

Description

technical field [0001] The invention relates to a composite shoe sole and a preparation method thereof. Background technique [0002] The traditional process of ethylene ethyl acetate copolymer (referred to as EVA) foaming material is to plasticize and granulate the EVA raw material, and then go through the processes of banburying, opening refining, sheeting, and foaming. Because EVA has good plasticity, elasticity, and processability, the foam midsole of the sole of general sports shoes is made of EVA foam material. At present, the midsole of most sports shoes is made of EVA foam material. [0003] Although the EVA foam material and rubber bonded outsole produced by traditional technology has relatively good plasticity and elasticity, its tear resistance is poor, and its resilience is not high. Therefore, it is necessary to provide a modified EVA foam material and a modified rubber adhesive bottom to improve its tear resistance, rebound, wear resistance and anti-skid perf...
