Preparation method of high-elasticity sole material

Abstract

The invention discloses a preparation method of a high-elasticity sole material. The method comprises the following preparation steps of adding 60-66 parts by mass of dimethylbenzene diisocyanate, 50-65 parts by mass of vinyl acetate copolymer (EVA), 10-12 parts by mass of rice bran, 30-35 parts by mass of polyether triatomic alcohol, 3-6 parts by mass of talcum powder, 6 parts by mass of octadeca-alkyl acid, 13-15 parts by mass of stannous octoate, 2.5 parts by mass of thiosulfuric acid salt and 3-3.5 parts by mass of naphthenic oil in a high speed stirring mixing machine for mixing for 15 minutes; then adding in a twin-screw extruder for fusion and stem grafting to obtain the sole material after 4 hours. The preparation method is simple in preparation process and low in production cost, and prepared products are high in abrasive resistance and have good elasticity.

Description

technical field [0001] The invention relates to a preparation method of a highly elastic shoe sole material. technical background [0002] Its finished product of existing EVA material is light, and molding is convenient, mainly by injection molding and compression molding, can be widely used in the preparation of shoe sole, the softness of material and elasticity meet the requirement but its intensity is still relatively poor, especially abrasion resistance is not ideal, reduces In order to further improve the performance of some shoe materials on the market, a large amount of fillers, resins and oils are generally added, which not only greatly increases the production cost, but also reduces the elasticity of the shoe materials. At the same time, these traditional manufacturing techniques are complicated and the production cost is relatively high. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies of the prior art and p...
