Abstract

The invention discloses a formula for a lightweight high-resilience SEBS foamed shoe sole. The lightweight high-resilience SEBS foamed shoe sole is composed of the following raw materials in parts bymass: 60-85 parts of polystyrene-ethylene-butadiene-styrene (SEBS), 10-20 parts of isoprene rubber (IR), 5-15 parts of an ethylene-vinyl acetate copolymer (EVA), 3-10 parts of talcum powder, 0.3-1 part of octyl stearate (ZnST), 0.3-1 part of stearic acid (STE), 0.5-2 parts of zinc oxide (ZnO), 0.1-0.5 part of a cross-linking agent, namely bis(tert-butylperoxyisopropyl)benzene (BIPB) and 2-4 partsof a foaming agent, namely azodicarbonamide (AC). The lightweight high-resilience shoe sole provided by the invention has the advantages of good aging resistance, light weight, high resilience, high comfort and the like, can be used as an outsole, an insole or an integral sole of slippers, sandals, casual shoes, tourist shoes, sneakers and the like, and can be extensively popularized.

Description

Technical field [0001] The present invention mainly relates to the technical field of foam sole processing, and specifically relates to a preparation method of a lightweight and high-rebound SEBS foam sole. Background technique [0002] my country is now the world's largest shoe-making and exporting country, with more than 30,000 shoe companies and an annual output of more than 10 billion pairs of shoes, accounting for about 70% of the world's total shoe-making. In recent years, with the development of my country's national economy and the improvement of living standards, consumers have increasingly higher requirements for shoes. They pay more attention to their beauty and elegance while paying more attention to their safety and comfort. However, the quality of footwear is closely related to the performance of sole materials. Moreover, with the continuous advancement and innovation of production technology, the types of sole materials are becoming more and more abundant, an...
