Abstract

The invention relates to the field of soles, and particularly discloses a wear-resistant sole and a production process thereof. The sole is prepared from the following raw materials by weight: 60-70 parts of natural rubber; 30-40 parts of butadiene rubber; 1.5-3 parts of sulfur; 1-2 parts of an accelerant; 8-10 parts of a foaming agent; 3-4 parts of zinc oxide; 4-6 parts of stearic acid; 35-40 parts of a reinforcing agent; 20-25 parts of a filling agent; and 1-2 parts of an anti-aging agent. The production process of the sole comprises the following steps of: S1, plastifying; S2, mixing; and S3, vulcanization. Through optimization design, the surface property of the reinforcing agent is improved, so that the reinforcing agent has an excellent dispersion effect in a rubber base material, the bonding performance is enhanced, the action effect of the reinforcing agent is exerted, and the sole has excellent wear resistance.

Description

technical field [0001] The invention relates to the field of shoe soles, more specifically, it relates to a wear-resistant shoe sole and a production process thereof. Background technique [0002] Shoes are varied according to the environment in which they are used, such as sandals, leather shoes, and sneakers. The characteristics of different types of shoes are also different. Among them, sports shoes such as hiking shoes, tennis shoes, basketball shoes, etc. are required to have the characteristics of cushioning and wear resistance, so as to ensure the comfort and durability of wearing. Abrasion resistance depends on the quality of the sole material, the common sole materials are rubber, polyurethane, EVA and so on. Among them, the rubber shoe material is the most wear-resistant and has good elasticity, which is suitable for the production of soles of various sports shoes. [0003] But generally speaking, after one or two years of use, the texture of the sole will be sev...
