Problems solved by technology

[0002] Sports shoes due to their special purpose and consumer experience needs, in order to meet the rebound requirements, the material hardness is generally high and the density is relatively high. At the same time, due to the single material used in the formula and the irrationality of the formula, sports shoes The weather resistance is relatively poor, and the deformation after compression is high. The foam material of the sole is easy to deform after wearing for a long time, and the wearing experience and appearance will be greatly affected.
To reduce the density of sports shoes materials, if the existing formula is used, the performance of rebound and compression resistance will also decrease significantly.

Abstract

The invention discloses a composition used for preparing a composite foaming material used for a sneaker sole and a preparation method. The composition is prepared from the following ingredients in parts by weight: 20-50 parts of blending-type polyurethane, 25-55 parts of ethylene-vinyl acetate copolymer, 15-30 parts of polyolefin thermoplastic elastomer, 10-15 parts of low-concentration polyethylene, 6-18 parts of ethylene-propylene-diene-terpolymer rubber, 3-5 parts of filler, 1.5-2.0 parts of zinc oxide, 0.4-0.6 part of stearic acid, 0.8-1.4 parts of zinc stearate, 0.1-0.4 part of crosslinking agent, 0.7-1.0 part of bridging agent, 2.5-3.5 parts of foamer. The manufacture method is characterized in that secondary mixing is mainly carried out, and then granulation and foaming are carried out. When the technical scheme of the invention is adopted, the prepared composite foaming material has the advantages of small density, softness, good anti-buffering performance, good elasticity, compression resistance and small compression deformation and is durable and comfortable.
