High-flexibility super non-slip wear-resistant foam material and preparation method thereof

Abstract

The invention provides a high-flexibility super non-slip wear-resistant foam material. The high-flexibility super non-slip wear-resistant foam material is prepared from the following raw materials inparts by weight: 70-120 parts of a plastic main material, 2-10 parts of polyisobutene, 5-10 parts of a wear-resistant agent, 0.6-1 part of a peroxide cross-linking agent, 1-2 parts by weight of a foaming agent, 0.5-1.5 parts by weight of zinc oxide, 0.6-1 part by weight of stearic acid and 0.5-1.5 parts by weight of zinc stearate, wherein the plastic main material is prepared from an ethylene-vinyl acetate copolymer, an ethylene-octene block copolymer, a hydrogenated styrene-butadiene block copolymer, brominated butyl rubber and solid crosslinkable polyether type polyurethane rubber. The high-flexibility super non-slip wear-resistant foam material provided by the invention adopts a plastic main material with specific composition, and is matched with other components with specific content to realize better interaction; the product has excellent flexibility, excellent skid resistance and good wear resistance at the same time, can solve the problem that skid resistance and wear resistanceof an existing EVA foamed shoe sole are difficult to consider at the same time, and meets the requirements of large-area exposed use and direct contact use of an EVA midsole.

Description

technical field [0001] The invention relates to the technical field of footwear manufacturing, and more specifically relates to a highly flexible, super anti-slip and wear-resistant foam material and a preparation method thereof. Background technique [0002] Consumers often need a pair of sports shoes that are soft, comfortable, wear-resistant and non-slip, but ordinary EVA foam sole materials are difficult to take into account both anti-slip and wear resistance, because ordinary EVA foam soles use silicone wear-resistant agents, and silicon Although ketone anti-wear agents can improve the wear resistance of foamed soles, the lubricity of silicone leads to a decrease in the anti-slip performance of the soles. The principles of anti-slip and wear resistance run counter to each other; and can a pair of sports shoes maintain good flexibility? Depends on sole material properties. Therefore, the development of a high-toughness, super wear-resistant and non-slip foaming material...

AI Technical Summary

Problems solved by technology

However, the DIN wear resistance of the foam material finally provided in this patent is between 247-327, and the static dry slip is 0.70-1.03

The Chinese patent application number 201811368746.2 discloses a formula for wear-resistant anti-slip EVA shoe sole material. The raw material composition includes 50-70 ethylene-vinyl acetate copolymer; 4-8 parts of inorganic flame retardant; -2 parts; 5-10 parts of anti-wear agent; 2-4 parts of zinc oxide; 0.5-5 parts of light stabilizer; 5-20 parts of nano-scale inorganic filler; 1-3 parts of foaming agent; 1 part; lubricant 1-3 parts; although the patent mentions the main components of the anti-slip agent, it does not mention what material to use to improve the anti-slip performance, and there is no final anti-slip data result in the patent

[0004] In summary, in the prior art, there is no shoe sole material that can simultaneously take into account flexibility, anti-slip properties and wear resistance.
