Abstract

The invention relates to the field of rubber and plastic foam materials, and concretely relates to a wear-resistant rubber and plastic foam shoe material and a preparation method thereof. The preparation method comprises the following steps: graphene and aluminum powder are mixed according to a mass ratio of 5:1, and the obtained mixture is smelted and mixed evenly at a high temperature of 660-680DEG C, and then is sprayed to obtain flaky nanoscale graphene/aluminum powder; polycarbonate diol is uniformly mixed with 4,4'-diphenylmethane diisocyanate and stannous octoate, then graphene/aluminum powder and sodium hexametaphosphate are added, and the obtained mixture is stirred and reacted at 80-100 DEG C so as to obtain a polyurethane elastomer; the polyurethane elastomer is mixed with EVA,NR rubber, an inorganic filler, a lubricant, sulfur, an AC foaming agent and an anti-aging agent in an internal mixer at 90-100 DEG C for 4-6 min, and then a sheet is discharged; and the sheet is cut, is implanted in a mold pressing machine and is foamed at 170-200 DEG C for 180-240 s to obtain the graphene-containing wear-resistant rubber and plastic foam shoe material. The shoe material has good low-temperature wear resistance.

Description

technical field [0001] The invention relates to the field of rubber and plastic foam materials, in particular to a wear-resistant rubber and plastic foam shoe material and a preparation method, in particular to a low-temperature wear-resistant ethylene-vinyl acetate copolymer foam shoe material and a preparation method. Background technique [0002] Foaming materials are obtained by adding catalysts, foam stabilizers, foaming agents and other auxiliary materials to plastics and other raw materials, and through physical foaming or cross-linking foaming, a large number of fine foams appear in plastics and other raw materials. The volume of plastic and other raw materials increases after foaming, and the density decreases, and the obtained foamed material has functions such as cushioning, shock absorption, and heat preservation. Ethylene-vinyl acetate copolymer (EVA) foaming material has excellent flexibility, elasticity and chemical corrosion resistance, and is gradually accep...
