Abstract

The invention discloses a PVC sole foaming material, which comprises the following components, by weight: 55-65% of PVC, 2-4% of ZnO, 1.3-1.4% of HSt, 1.5-2% of an anti-aging agent, 11-13% of carbon black, 11-13% of CaCO3, 6-8% of DOP, and 2-4% of a foaming agent. The prepared PVC sole foaming material has characteristics of good elasticity, low density, flexibility, and low shrinkage deformation rate.

Description

Technical field: [0001] The invention relates to the technical field of shoe materials, in particular to a PVC shoe sole material. 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, etc. It is widely used in engineering construction, food packaging, electrical and shoemaking industries. [0003] When PVC is used to make shoe soles, polyvinyl chloride 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. However, its impact resistance, heat resistance and light stability are poor, especially low temperature brittleness and flexibility. [0...
