1. secondary mould pressing sandwich EVA foaming abrasion-proof sports shoes bottom, it is characterised in that it is wear-resisting under to be equipped with the upper wear-resisting bed of materialThe bed of material, the upper wear-resisting bed of material and under the ultralight bed of material is equipped between the wear-resisting bed of material;

  • The upper wear-resisting bed of material raw material of the wear-resisting bed of material by mass percentage under, which forms, is:

    Ethylene-vinyl acetate is copolymerizedObject 50%~70%, ethylene-octene copolymer 10%~18%, ethylene propylene diene rubber 5%~10%, talcum powder 2%~5%,Anti-wear agent 5%~8%, stearic acid 0.3%~0.6%, zinc stearate 0.5%~0.8%, zinc oxide 0.8%~1.2%, mistakeAoxidize diisopropylbenzene (DIPB) 0.35%~0.45%, azodicarbonamide 2.5%~3%, Masterbatch 2%~3%;

    The raw material group of the ultralight bed of material by mass percentage becomes:

    Ethylene-vinyl acetate copolymer 60%~70%, secondAlkene-octene copolymer 15%~25%, ethylene-acrylic acid copolymer 3%~5%, talcum powder 2%~4%, stearic acid 0.3%~0.6%, zinc stearate 0.5%~0.8%, zinc oxide 1%~1.5%, cumyl peroxide 0.35%~0.45%, occasionallyNitrogen diformamide 4%~4.5%, Masterbatch 2%~3%.
