Composition and preparation method for preparing wear-resistant waterproof high-elasticity foaming materials

Abstract

The invention discloses a composition and a preparation method for high-elasticity wear-resistant foaming materials, wherein the composition comprises, by mass, 20-65 parts of a polyether type polyurethane rubber, 20-65 parts of an ethylene-vinyl acetate copolymer, 7-18 parts of a polyolefin thermoplastic elastomer, 3-8 parts of a polybutadiene rubber, 5-15 parts of ethylene propylene diene monomer, 5-10 parts of a reinforcing agent, 0.3-1 part of a coupling agent, 1.0-2.0 parts of zinc oxide, 0.5-1.0 part of stearic acid, 0.8-1.5 parts of zinc stearate, 0.5-1.5 parts of a cross-linking aid, 1.0-2.5 parts of a vulcanizing agent, and 1.5-3.5 parts of a foaming agent. The preparation method mainly comprises: two mixing, granulation, and foaming. According to the present invention, by adopting the technical scheme, the obtained foaming material product has advantages of small density, softness, wear resistance, excellent anti-cussion performance, good elasticity, compression resistance, small compression deformation and folding deformation resistance.

Description

technical field [0001] The invention relates to the field of rubber-plastic blending and foaming manufacturing, in particular to a composition for preparing highly elastic and wear-resistant foaming materials and a preparation method thereof. Background technique [0002] Due to their special purpose properties and consumer experience needs, shoe soles and cushion products generally have high hardness and high density in order to meet the rebound requirements. At the same time, due to the single material used in the formula and the irrationality of the formula, The weather resistance is relatively poor, the deformation after compression is high, the product is easy to deform, and the wear resistance is poor. To reduce the density of the material, if the existing formula is used, the corresponding performance such as rebound and compression resistance will also decrease significantly. In order to solve the current problems, it is necessary to develop a highly elastic and wea...
