Example Embodiment

[0030] The present invention will be further described below in conjunction with the embodiments.

[0031] In this embodiment, the weight percentage of each material of the sports shoe sole is composed as follows:

[0032] Ethylene-vinyl acetate copolymer (VA content 26%) 45%;

[0033] Ethylene-vinyl acetate copolymer (VA content 40%) 20%;

[0034] Ethylene-octene copolymer 15%;

[0035] EPDM rubber 13.5%;

[0036] Transparent zinc oxide 1.5%;

[0037] Stearic acid 0.5%;

[0038] White foaming agent 4%;

[0039] Crosslinking agent 0.5%.

[0040] among them:

[0041] 1. Ethylene-vinyl acetate copolymer is abbreviated as EVA. In this case, the VA content of 26% is EVA 7470 of Taiwan Plastics Corporation, and the VA content of 40% is EVA 40W of Dow.

[0042] 2. Ethylene-octene copolymer is abbreviated as POE, and the POE9061 of Exxon Mobil Corporation is used in this case.

[0043] 3. In this case, EPDM3745P from Dow Company is used in EPDM rubber.

[0044] 4. The transparent zinc oxide used in thi...

Abstract

The invention discloses a sports shoe sole material. The elasticity of a sports shoe sole prepared by virtue of the technical scheme of the invention is 71 percent, the heat shrinkage rate is 1.2 percent, the compression deformation rate is 30 percent, the hardness is 50 degrees, and the density is 0.18 g/cm3. The sports shoe sole material formula consists of the following components by weight percent: 40 to 50 percent of vinyl-vinyl acetate copolymer (the content of VA is 26 percent); 15 to 25 percent of vinyl-vinyl acetate copolymer (the content of VA is 40 percent), 20 to 30 percent of vinyl-octylene copolymer, 10 to 15 percent of EPDM, 1 to 1.5 percent of transparent zinc oxide, 0.4 to 0.6 percent of stearic acid, 3.5 to 4.5 percent of white foaming agent, and 0.4 to 0.6 percent of cross-linking agent.

Description

technical field [0001] The invention belongs to the field of sports shoe materials, in particular to a sports shoe sole material with high resilience performance. Background technique [0002] The energy return of running shoes is an important factor to measure its quality. The better the energy return, the less extra work the human body consumes when wearing the shoes, which also means that the more effort is saved when wearing the shoes. According to research by experts in the field of sports and shoemaking, there are two factors that affect the energy return of running shoes, one is the structural design of the sole, and the other is the rebound performance of the sole material itself. Due to the difference in formula ingredients or content, the rebound elasticity, compression deformation and thermal compression of the soles are quite different. In terms of sole materials, most of the shoemaking industry currently adopts EVA (vinyl acetate copolymer) foaming technology. ...
