[0049] In order to better explain the research results, the ratio of the soft, high-elastic and wear-resistant EVA foam shoe material was changed respectively so that some of the raw materials were not within the set range. Comparative Example 1 (see Table 8) was to change the main components of the two materials. The ratio of the rubber material is not within the set range. Comparative example 2 (see Table 9) is to change the auxiliary materials of the two materials so that it is not within the set range, and m...

Abstract

The invention discloses a flexible, highly-elastic and wear-resistant EVA foamed shoe and a manufacturing method thereof, and relates to a shoe. Raw materials of the foamed shoe comprise 40-54% of an ethylene-vinyl acetate copolymer, 10-16% of a hydrogenated styrene-butadiene-styrene block copolymer, 10-16% of an ethylene-butylene copolymer, 8-12% of an olefin block copolymer, 5-8% of a wear resisting agent, 3-5% of talcum powder, 0.3-0.5% of stearic acid, 0.5-0.8% of zinc stearate, 0.6-1.0% of zinc oxide, 0.5-0.6% of di(tert-butylperoxyisopropyl)benzene, 1.6-2.0% of azodicarbonamide and 2-3% of color master batch. The manufacturing method comprises the following steps: mixing di(tert-butylperoxyisopropyl)benzene with azodicarbonamide to obtain a mixture A, mixing remaining raw materials, internally mixing the remaining raw materials, heating the remaining raw materials, adding the mixture A, internally mixing the remaining raw materials and the mixture A, and thinning the obtained mixture; granulating the thinned mixture; standing the granulated mixture, injecting the obtained mixture to a shoe die, and molding the injected mixture; and carrying out sole fixing to form the foamed shoe.

Description

technical field [0001] The invention relates to a shoe material, in particular to a soft, highly elastic and wear-resistant EVA foam shoe material and a manufacturing method thereof. Background technique [0002] With the development of Chinese sports brands, my country's sports brands need to be upgraded. The era of blindly relying on appearance and ignoring the function of shoe materials to attract consumers has passed. Shoe materials are the core technology in the field of shoes. A pair of shoes is comfortable to wear. The performance of the original shoe material accounts for more than 70%; it can also be said that 70% of the technical content of a pair of shoes is concentrated on the shoe material. How can we compete with international sports brands and develop shoe materials with our own characteristics, so as to truly occupy a place in the field of shoe materials. [0003] Of course, my country started relatively late in the field of petrochemical synthesis, and most ...
