Problems solved by technology

EVA is a copolymer made of ethylene-vinyl acetate, referred to as EVA. The EVA midsole refers to the shoe midsole that is molded after injecting EVA into the mold and then heated at a high temperature. However, the EVA sole has poor wear resistance and often needs to be combined with rubber. Bottom fit prepared into sole material
This method often needs to polish the rubber outsole first, then treat the rubber outsole and the EVA midsole with a treatment agent, and then use glue to bond the rubber outsole and the EVA midsole. Glue pollut

Abstract

The invention relates to a non-gumming wear-resistant sole by regulating the formula and process of various components of the sole. The non-gumming wear-resistant sole contains the following components in parts by weight: 30-50 parts of EVA (Ethylene-Vinyl Acetate), 10-20 parts of calcium stearate, 5-10 parts of nano calcium carbonate, 5-10 parts of zinc stearate, 20-30 parts of butadiene styrenerubber, 10-15 parts of ethylene-propylene-diene monomer, 5-8 parts of nano-titanium oxide, 1-3 parts of a vulcanizing agent, 2-5 parts of a bridging agent, 5-10 parts of a compatilizer, 2-8 parts of an anti-aging agent, 5-15 parts of epoxy resins, 5-15 parts of polyacrylate, 20-30 parts of polyvinyl alcohol and 2-5 parts of a foaming agent. Therefore, the prepared sole is excellent in mechanical property and excellent in high temperature resistance. The polyvinyl alcohol can achieve an excellent bonding effect, has high heat resistance, and achieves an excellent bonding effect when matched with polyacrylate.

Description

technical field [0001] The invention relates to the technical field of shoe sole preparation, in particular to a non-degumming wear-resistant shoe sole and a preparation method thereof. Background technique [0002] Shoes are items that we often use in our daily life, and the sole is an essential part of making shoes. Among them, since EVA foam sports soles entered the Chinese market, due to their lightness, good elasticity, strong toughness, and comfortable feet The advantages have been praised and recognized by the majority of consumers. EVA is a copolymer made of ethylene-vinyl acetate, referred to as EVA. The EVA midsole refers to the shoe midsole that is molded after injecting EVA into the mold and then heated at a high temperature. However, the EVA sole has poor wear resistance and often needs to be combined with rubber. The bottom fit is prepared as a sole material. This method often needs to polish the rubber outsole first, then treat the rubber outsole and the EVA...
