Abstract

The invention discloses a high-elasticity wear-resistant polyurethane foaming shoe material and a preparation method thereof. The shoe material is prepared from the following components in parts by weight: 50-70 parts of thermoplastic polyurethane elastomer, 10-20 parts of styrene-butadiene-styrene block copolymer, 10-15 parts of butadiene styrene rubber, 10-20 parts of ethylene-octene copolymer,1-5 parts of a foaming agent, 0.5-1 part of zinc oxide, 2-4 parts of a cross-linking agent, 1-2 parts of an assistant cross-linking agent, 5-8 parts of an active agent and 10-20 parts of filler. The problem that an existing shoe material does not have elasticity and is poor in wear-resisting comprehensiveness and portability can be solved.

Description

technical field [0001] The invention relates to a foamed shoe material, in particular to a highly elastic and wear-resistant polyurethane foamed shoe material and a preparation method thereof. Background technique [0002] With the rapid development of the footwear industry, the varieties of sole materials are increasingly diversified. The polyvinyl chloride and rubber solid soles that dominate the traditional footwear industry have been gradually replaced by the emerging rubber and plastic foam shoes. The main materials of foam soles generally include polyvinyl chloride (PVC), polyethylene (PE), styrene-butadiene-styrene copolymer (SBS), polyurethane (PU), ethylene-vinyl acetate copolymer (EVA) )Wait. [0003] Thermoplastic polyurethane elastomer (TPU) is a commonly used shoe sole material, which has many advantages: low density, soft texture, comfortable and light to wear; good dimensional stability, long storage life; excellent shock absorption and anti-skid performance...
