Abstract

The invention discloses a tear-resistant antistatic EVA (ethylene-vinyl acetate copolymer) foamed shoe material which is prepared from the following raw materials in parts by weight: 45-55 parts of EVA, 25-35 parts of polyolefin block copolymer, 10-15 parts of ethylene-acrylic acid copolymer, 6-12 parts of calcium carbonate, 0.5-1 part of stearic acid, 1.5-2.5 parts of zinc stearate, 0.5-1.5 parts of magnesium oxide, 0.6-1.2 parts of dicumyl peroxide, 2-2.5 parts of azobisformamide and 2-3 parts of antistatic agent. Compared with the existing EVA foamed shoe material, the tear-resistant antistatic EVA foamed shoe material disclosed by the invention has the original physical properties of the EVA foamed material, overcomes the defects of high tear tendency and high damage tendency in the traditional EVA foamed shoe, increases the design space for various shoes, enhances the antistatic property of the shoe sole, and has very good use effect.

Description

Technical field: [0001] The invention relates to the technical field of shoe materials, in particular to an EVA foamed shoe material. Background technique: [0002] China is a big producer of footwear, and it has everything for shoes. With the progress of the times, people's quality of life improves, consumption and life concepts change, and the pursuit of comfort, fashion, and convenience is the direction of footwear development. EVA foam shoe materials have been popular for many years in the development of shoe materials. It is light, comfortable, and durable. Traditional EVA foam shoes have low tear strength, easy to break, and are not durable. At the same time, due to the tear strength Increase, the formula of EVA foam shoe material with tear resistance and durability has not been reported. At present, there is a need for tear-resistant EVA shoe materials, which can be stitched with various leather and fabrics, which increases the design space of various shoes. [0003] In th...
