▎ 摘  要

NOVELTY - High-elasticity wear-resistant sole material, comprises 30-35 pts. wt. ethylene-vinyl acetate copolymer, 65-70 pts. wt. ethylene-octylene copolymer, 3-3.5 pts. wt. talc powder, 2.5-3 pts. wt. foaming agent, 0.8-0.85 pts. wt. crosslinking agent, 1-1.5 pts. wt. zinc oxide, 0.6-0.8 pts. wt. stearic acid, 3-3.5 pts. wt. titanium pigment and 0.2-0.24 pts. wt. pigment. USE - The high-elasticity wear-resistant sole material is useful in sport shoe. ADVANTAGE - The material: has low density, wear resistance, rebound resilience and strong compression resistance; ensure the excellent comprehensive performance, elasticity, fluidity, strong anti-shrinking property, flexibility and impact resistance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the high-elasticity wear-resistant sole material, comprising (1) mixing an ethylene-vinyl acetate copolymer and an ethylene-octene copolymer, extruding and granulating to obtain blended particles, (2) mixing the blending particles, talc powder, zinc stearate, pigment, high-elasticity silica aerogel, wear-resistant material, zinc oxide and titanium dioxide, carrying out 7 times of banburying and turning, and adding a foaming agent and a cross-linking agent during the 5th banburying and turning to obtain a mixture, (3) thinning the mixture at 75-95℃ for 3 times to obtain a sheet material, (4) granulating the sheet materials to obtain granules with the particle size of 2-4 µm, and (5) carrying out injection molding on the granules to obtain the final product.
