Abstract

The invention relates to the technical field of high polymer materials, and especially relates to a shock-absorbing rubber and plastic foam material for soles, and a preparation process thereof. The foam material comprises nitrile rubber, an ethylene-octene copolymer, ethylene propylene diene monomer, carbon nanofibers, an organic silicon flame retardant, nanometer zinc oxide, calcium carbonate, an anti-aging agent, an assistant cross-linking agent and a coupling agent. The carbon nanofibers and the ethylene-octene copolymer are selected and are mixed with the nitrile rubber and the ethylene propylene diene monomer, the damping performance of the rubber material is improved by introducing the carbon fibers and alkene groups, the network crosslinking degree of the rubber material is improved through the assistant crosslinking agent and the coupling agent, and then the damping performance of the foam material is further improved. Therefore, the shock-absorbing rubber and plastic foam material for soles has the advantage of good shock-absorbing effect. The preparation process of the shock-absorbing rubber and plastic foam material for soles has the characteristics of simple process, low production cost and suitability for large-scale production.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a shock-absorbing rubber and plastic foam material for shoe soles and a preparation process thereof. Background technique [0002] With people's pursuit of the performance of sporting goods, the performance requirements for sports shoes such as light weight, high elasticity, and shock absorption are gradually increasing. The shock absorption system is a very important part of sports shoes. The shock-absorbing function of the sole is the ability to absorb or reduce the shock wave, which can be realized by a good shock-absorbing structure or a material with good shock-absorbing ability. [0003] Rubber and plastic insulation materials are made of nitrile rubber and polyvinyl chloride with excellent wear-resistant, heat-resistant and flame-retardant properties, and are made by adding a foaming agent after banburying and foaming. It is a flexible foam containing a large num...
