Abstract

The invention discloses a tear-resistant EVA (ethylene-vinyl acetate copolymer) foamed shoe material which is prepared from the following raw materials in parts by weight: 50-55 parts of EVA, 15-25 parts of hydrogenated styrene-butadiene-styrene block copolymer, 10-15 parts of ethylene-octylene copolymer, 5-10 parts of calcium carbonate, 0.5-1.2 parts of stearic acid, 1.5-2.5 parts of zinc stearate, 0.8-1.6 parts of magnesium oxide, 0.5-1.2 parts of dicumyl peroxide, 1.5-2.8 parts of azobisformamide and 2.5-3.5 parts of color master batch. Compared with the existing EVA foamed shoe material, the tear-resistant EVA foamed shoe material disclosed by the invention has original excellent physical properties of the traditional EVA foamed shoe material, can overcome the defects of high tear resistance and high damage tendency in the traditional EVA foamed shoe so as to increase design space for various shoes, and is more comfortable for consumers to wear. The tear-resistant EVA foamed shoe material has the advantages of low cost and simple preparation technique.

Description

A kind of anti tear EVA foaming shoe material
Technical field:
The present invention relates to footwear material technical field, relate in particular to a kind of EVA foaming shoe material.
Background technology:
China is the big producing country of footwear, and all kinds of footwear are complete, along with the progress in epoch, the raising of people's quality of the life, the transformation of consumption, philosophy of life, pursue comfortable, fashion, convenient be the direction of footwear development.EVA foaming shoe is to take EVA as major ingredient, light, soft, the comfortable footwear that obtain through specific moulding process.Traditional E VA foaming shoe, tear strength is low, cracky, slimsy, and because of the increase of tear strength, the formula with anti tear, prolonged endurable EVA foaming shoe material have not been reported simultaneously.Need at present can anti tear EVA footwear material, carry out sewing machine processing with various claddings, cloth, increased the design space of all kinds of footwear.
Summary of the invention:
The object of the present invention is to provide a kind of anti tear EVA foaming shoe material, it had both had the original superior physical properties of EVA foam material, had overcome again that traditional EVA foaming shoe is easily torn, the defect of cracky.
For achieving the above object, a kind of anti tear EVA foaming shoe material of the present invention, is comprised of the raw material with following weight part proportioning:
Ethylene-vinyl acetate copolymer: 50～55 parts;
Hydrogenated styrene-butadiene-styrene block copolymers: 15～25 parts;
Ethylene-octene copolymer: 10～15 parts;
Calcium carbonate: 5～10 parts;
