Abstract

APVC sole material is prepared from components in parts by weight as follows: 59 parts of PVC, 10 parts of polyethylene glycol, 10 parts of perlite powder, 10 parts of grinding wheel ash, 3 parts of an accelerator, 15 parts of a foaming agent, 5 parts of a surfactant, 6 parts of a plasticizer, 13 parts of modified PP and 11 parts of silkworm shit. The PVC sole material has higher corrosion resistance and aging resistance, also has better toughness and strength, has a good adsorption effect on sweat stains and foot odors and thus is suitable for preparation of most shoes.

Description

technical field [0001] The invention relates to the field of shoe sole materials, in particular to a PVC shoe sole material and a preparation method thereof. Background technique [0002] PVC is one of the five most used synthetic resins in the world. It is a thermoplastic linear polymer produced by free radical polymerization of vinyl chloride monomer. PVC material has the advantages of high strength, low price, good chemical corrosion resistance, good electrical insulation and difficult to burn, and is widely used in engineering construction, food packaging, electrical and shoemaking. [0003] When PVC is used to make shoe soles, it has high mechanical strength, good acid and alkali resistance, dielectric properties and insulation properties. Compared with ordinary rubber, it also has better wear resistance and flame retardancy. Therefore, it has been favored by many shoe-making enterprises. However, its impact resistance, heat resistance and light stability are poor, e...
