Abstract

The invention discloses a wear-resistant sole material and a preparation method thereof. The wear-resistant sole material comprises the following raw materials in parts by weight: 30-40 parts of natural rubber, 20-30 parts of corrosion-resistant rubber, 30-50 parts of an ethylene-vinyl acetate copolymer, 10-20 parts of a wear-resistant composite material, 10-15 parts of a plasticizer and 1-3 partsof a stabilizer. The preparation method comprises the following steps: adding the natural rubber, the corrosion-resistant rubber, the ethylene-vinyl acetate copolymer, the wear-resistant composite material, the plasticizer and the stabilizer into a kneading machine, kneading for 2 hours at the temperature of 80-100 DEG C to prepare a mixture, adding the mixture into a plasticator, plastifying andpulling sheets, and controlling the plastifying temperature to be 100-120 DEG C to prepare a primary sheet material; the active silica group and the active hydrogen are subjected to the ring-openingreaction, and the product 2 is grafted on the methyl phenyl silicon so that the technical problem of poor compatibility between the product 1 and the methyl phenyl silicon rubber is solved, and the prepared sole material can be endowed with excellent corrosion resistance.

Description

technical field [0001] The invention belongs to the technical field of shoe sole material preparation, in particular to a wear-resistant shoe sole material and a preparation method thereof. Background technique [0002] Compared with other foaming materials, PVC foaming materials have the advantages of good mechanical properties, good adhesion, convenient processing, and low cost. With the rising price of raw materials, PVC foam sole materials are becoming more and more popular. Ethylene-vinyl acetate copolymer (EVA) has good plasticity, elasticity and processability, and the foamed material has the advantages of low density, good mechanical properties, and easy coloring. It is widely used in shoe sole materials, but EVA materials It has the disadvantage that the wear resistance is not as good as that of rubber shoe materials, which limits its partial application. However, although the ordinary PVC foam sole material is lighter, it loses wear resistance and affects the serv...
