Problems solved by technology

EVA (ethylene-ethyl acetate copolymer) foaming material is a non-toxic foaming material with excellent physical properties. It is widely used in the production of shoe soles. The softness and elasticity of the material are not good, even if the part is soft. It meets the requirements, but its strength is still poor, especially the wear resistance is not ideal, and when the wear resistance is improved, the flexibility and resilience of the material become worse

Abstract

The invention discloses a light, soft and elastic novel rubber and plastic composite material which comprises 24-35 parts of ethylene-vinyl acetate (EVA), 28-42 parts of ethylene propylene diene monomer rubber (EPDM), 9-18 parts of polyolefin elastomer (POE), 9-18 parts of an olefin block copolymer (OBC), 3-10 parts of wear-resistant oil, 0.2-3 parts of zinc oxide, 0.1-1 part of stearic acid, 0.1-1 part of an adhesive and 1-3 parts of an AC foaming agent. According to the invention, compatibility and combinability of the component materials are improved by introducing corresponding assistantsinto the formula, so that strength and wear resistance of the blend material are improved. Meanwhile, the modified EPDM and wear-resistant oil are introduced into the formula, so that resilience and flexibility of the material are greatly improved.

Description

technical field [0001] The invention relates to the field of shoe sole material formulations, in particular to a new type of light, soft and elastic rubber-plastic composite material. Background technique [0002] The construction of the sole may generally include an outsole, a midsole, an insole, and a heel. EVA (ethylene-ethyl acetate copolymer) foaming material is a non-toxic foaming material with excellent physical properties. It is widely used in the production of shoe soles. The softness and elasticity of the material are not good, even if the part is soft. It meets the requirements, but its strength is still poor, especially the wear resistance is not ideal, and when the wear resistance is improved, the flexibility and resilience of the material become worse. Contents of the invention [0003] The object of the present invention is to solve the above technical problems and provide a new type of light, soft and elastic rubber-plastic composite material. The sole mad...
