Abstract

The invention discloses a soft and flexible EVA (ethylene-vinyl acetate copolymer) foam sports shoe material and a method for manufacturing the same, and relates to an EVA foam shoe material. The soft and flexible EVA foam sports shoe material comprises ethylene-vinyl acetate copolymers, ethylene-octene copolymers, ethylene-acrylic acid copolymers, talc powder, stearic acid, zinc stearate, zinc oxide, dicumyl peroxide, azodicarbonamide and color master batches. The method includes mixing the dicumyl peroxide and the azodicarbonamide with each other for standby application, mixing remaining raw materials with one another to obtain mixtures, pouring the remaining materials into a banbury mixer, carrying out first-stage banburying on the mixtures to uniformly mix the materials, adding mixtures of the dicumyl peroxide and the azodicarbonamide into the materials when the temperatures of the materials reach 100-105 DEG C, starting the banbury mixer again to carry out second-stage banburying on the materials and the mixtures of the dicumyl peroxide and the azodicarbonamide until the temperatures of the materials and the mixtures rise and reach 105-110 DEG C, uniformly mixing all raw materials to obtain mixtures which are subjected to effective banburying, thinning the mixtures twice and granulating the mixtures; allowing grains to stand for 24h, then pouring the grains into shoe molds, vulcanizing the grains, molding the grains and setting the grains to obtain the soft and flexible EVA foam sports shoe material.

Description

technical field [0001] The invention relates to an EVA foamed shoe material, in particular to a soft and flexible EVA foamed sports shoe material and a manufacturing method thereof. Background technique [0002] my country is a big producer of footwear, and there are all kinds of shoes, especially the sudden emergence of sports brands in the past ten years. Sports brands have experienced the appearance imitation in the era of public models, to the structure and appearance imitation in the era of private models, to independent design, and to today's The functional shoe material is the leading factor, so that my country's sports brands have moved from Made in China to Created in China. Entering the era of independent creation of sports shoe materials, the R&D personnel of shoe materials have come to the foreground of history from behind the scenes. For a pair of sports shoes, 70% of its main technology is concentrated on the sole, and the performance of the shoe material direc...
