Problems solved by technology

The EVA outsole made of this traditional formula is characterized by light weight, but because the main component is EVA, the wear resistance is poor by about 15-20%, and the production process is complicated, so the production capacity is not high, and the cost is relatively high

Abstract

The invention discloses an ultra-light modified thermoplastic rubber TE material, relating to thermoplastic rubber materials. The ultra-light modified thermoplastic rubber TE material comprises the following components in percentage by weight: 15-30% of thermoplastic elastomer (TPE), 5-10% of hydrogenated styrene-butadiene-styrene (SEBS) block copolymer, 20-40% of ethylene (E) and vinyl acetate (VA) EVA, 5-15% of ethylene octylene copolymer (POE), 15-25% of thermoplastic butadiene styrene rubber styrene-butadiene-styrene (SBS), 1-5% of poly-alpha-methyl styrene resin (ATL), 1-15% of softened oil, 1-5% of zinc oxide (ZnO), 1-3% of ultraviolet resistant agent (UV), 1-3% of antioxidant, 1-3% of titanium white, 1-3% of ultralight foaming powder, 1-3% of low-temperature expanding agent, and 1-3% of white foam which are mixed and injection-molded. In another formula, environment-friendly filling materials are used for replacing the ethylene octylene copolymer (POE) and the zinc oxide (ZnO) filling materials, the ultraviolet resistant agent, the antioxidant and the titanium white, and the purposes of protecting the ecological environment and effectively utilizing waste resources are achieved. The ultra-light modified thermoplastic rubber TE material has the advantages that the flexibility and rebound elasticity are better in large sole, the weight is lighter and the cost is low. The energy productivity is higher than that of the traditional thermoplastic rubber (TPR) by 20%-30% and is 3-4 times that of the traditional EVA.

Description

Technical field: [0001] The invention relates to a thermoplastic rubber material, in particular to a modified thermoplastic rubber TE material for making outsoles of shoes. Background technique: [0002] The sole is an important part of shoes, how to reduce the cost of the outsole and meet the international market testing requirements and consumer demand is one of the important competitiveness. At present, there are many kinds of sole materials available on the market, with different patterns, such as rubber, thermoplastic rubber, polyurethane or thermoplastic polyurethane, etc., while the typical formula of traditional thermoplastic rubber TPR is thermoplastic elastomer TPE 58-65%, poly α methyl styrene resin ATL3-5%, nano-calcium CCR20-25%, polystyrene PS12-16%, thermoplastic styrene-butadiene rubber SBS 2-5%, softening oil 5-10%, anti-purple agent UV (model 301) 1-3%, antioxidant ANTIOXIDANTS (model TM-3) 1-3%, titanium dioxide TITANIUM DIOXIDE (model K930) 1-5%, ultra-l...
