Problems solved by technology

The common rubber shoes commonly used at present with weather resistance and wear resistance are of low quality, not weather resistant, not durable, low fatigue resistance, easy to crack, and not good enough in quality and reliability
[0003] Moreover, more leftover materials are often produced in the production process, and these leftover materials often cannot be recycled directly, so a large amount of losses are caused.

Abstract

The invention discloses a light wear-resisting and high-elasticity rubber sole material. The light wear-resisting and high-elasticity rubber sole material is prepared from raw materials as follows: butadiene rubber, natural rubber, an ethylene-vinyl acetate copolymer, white carbon black, a dispersing agent, polyethylene with ultralow molecular weight, polyethylene glycol, an active agent, a bridging agent, a foaming agent and the like. The rubber sole material has the characteristics of being light, wear-resisting and high in elasticity, has the feature that the leftover materials produced in a sole processing process are recyclable, and can be widely applied to the shoemaking field of middle-grade and high-grade soles with higher requirements for properties such as light weight, wear resistance, comfort and the like.

Description

technical field [0001] The invention relates to a formula for rubber soles, in particular to a process for recycling light-weight wear-resistant high-elasticity rubber sole materials and leftover materials. Background technique [0002] There are thousands of formulas and manufacturing methods for rubber compositions, and different material formulas are often provided according to different use requirements. The common rubber shoes commonly used at present with weather resistance and wear resistance are of low quality, not weather resistant, not durable, low fatigue resistance and flexibility, easy to crack, and not good enough in quality and reliability. [0003] And, often can produce more leftover materials in the production process, these leftover materials often can't directly recycle, therefore, cause a large amount of losses. Contents of the invention [0004] In view of the above problems, the present invention provides a lightweight wear-resistant high-elastic ru...
