Abstract

The invention provides a foaming composition for a wear and skid resistant sole. The foaming composition comprises 30-90wt% of a thermoplastic elastomer, 0-50wt% of rubber, 0-30wt% of an ethylene-vinyl acetate copolymer, 0-30wt% of polyethylene, 5-20wt% of a filler, 0.5-2wt% of a surfactant, 0.5-4wt% of a coupling agent, 0.5-3wt% of a cross-linking agent, 1-4wt% of a foaming agent and 1-5wt% of a filler. The foaming composition simultaneously has the wear resistance and the skid resistance, and also has the respective superior characteristics of traditional rubber and PU. The invention also provides a preparation method of the foaming composition for a wear and skid resistant sole.

Description

technical field [0001] The invention relates to the field of polymer foaming materials, in particular to a foaming composition for wear-resistant anti-slip shoe soles and a preparation method thereof. Background technique [0002] Sole foam material is currently one of the most commonly used sole materials in the field of shoemaking. Because of its good elasticity and high strength, the foam material is widely used in the preparation of sports shoes and casual shoes. [0003] Common sole foam materials currently on the market include rubber foam soles and 3D EVA foam soles. For rubber foam soles, after the rubber is foamed, the physical properties will be greatly reduced, especially the wear-resistant physical properties will be deteriorated; the rubber coloring degree is poor, affected by color restrictions; the rubber fluidity is poor, not suitable for injection Bubble, narrow range of application. Common EVA foam soles have severe plastic feel, poor elasticity, poor fle...
