Antiskid anti-abrasion EVA shoe sole material and preparation method thereof

Abstract

The invention discloses an antiskid anti-abrasion EVA shoe sole material. The antiskid anti-abrasion EVA shoe sole material is mainly prepared from EVA, POE, EPDM, an anti-abrasion agent, talcum powder, propylenebutadiene rubber, an odorless cross-linking agent, stearic acid, active zinc oxide and a foaming agent in steps of mixing and foaming. The content of each component is as follows: 10 to 30 parts by weight of EVA, 6 to 15 parts by weight of POE, 10 to 20 parts by weight of EPDM, 0.6 to 1.2 parts by weight of anti-abrasion agent, 15 to 25 parts by weight of talcum powder, 3 to 8 parts by weight of propylenebutadiene rubber, 0.2 to 0.5 parts by weight of odorless cross-linking agent, 0.3 to 0.8 parts by weight of stearate acid, 0.4 to 0.8 parts by weight of active zinc oxide and 0.5 to 1 part by weight of foaming agent. The preparation method mainly comprises three steps of internal mixing, open mixing and oil pressing, and the EVA shoe sole material with hardness of 65 to 70 degrees is finally obtained by virtue of foaming and vulcanization. The prepared EVA shoe sole material is modified in a co-polymerization way by utilizing the rubber elastomer, and corresponding functional additives are added into the raw material formula, so that the antiskid anti-abrasion EVA shoe sole material has advantages of small hardness, high elasticity, good abrasion resistance, good antiskid performance, good dimensional stability, good mechanical performance, long service life and the like.

Description

technical field [0001] The invention relates to the field of organic polymer materials, in particular to a non-slip and wear-resistant EVA sole material and a preparation method thereof. Background technique [0002] Ethylene-vinyl acetate copolymer is referred to as EVA, and the general vinyl acetate (VA) content is 5% to 40%. Compared with polyethylene, EVA is widely used in foamed shoes due to the introduction of vinyl acetate monomer in the molecular chain, which reduces the high crystallinity and improves flexibility, impact resistance, filler compatibility and heat sealing performance. material, functional shed film, packaging film, hot melt adhesive, wire and cable, toys and other fields. Shoe material is the most important application field of EVA resin in my country. In the EVA resin used in shoe materials, the vinyl acetate content is generally 15% to 22%. Because EVA resin blended foam products have softness, good elasticity, and chemical corrosion resistance, ...

AI Technical Summary

Problems solved by technology

[0003] But at present, most of the rubber and plastic foam materials used for shoe soles have the following disadvantages: 1) the proportion is large, and the feeling of wearing is relatively cumbersome; 2) the wear resistance is poor and the service life is short, so it is not suitable for some wear resistance 3) poor elasticity, not suitable for hard roads or places with high requirements for elasticity; 4) poor skid resistance, when walking on a slippery road, the friction between the sole and the road is not large enough
