Abstract

The invention discloses a low-temperature-resistant PVC sole material. The low-temperature-resistant PVC sole material is prepared from, by weight, 60-80 parts of PVC, 20-30 parts of PC, 4-8 parts of calcium carbonate, 1.5-2.5 parts of antiager, 2-4 parts of carbon black, 2-4 parts of foaming agent and 5-10 parts of terephthalyl alcohol. Compared with a PVC material in the market, the PVC sole material which is formed through the formula and the preparing method by adding a certain amount of PV material and foaming the materials has high cold resistance and can still keep high physical performance in a low-temperature environment without losing elasticity or breaking.

Description

technical field [0001] The invention relates to a shoe sole material, in particular to a PVC shoe sole material. Background technique [0002] Most of the soles currently on the market are made of rubber and EVA foam, but because these two types of materials still have relatively large deficiencies, such as relatively expensive raw materials and environmental pollution, people are always looking for alternative products. The PVC material sole is one of them. PVC material has the characteristics of flame retardancy, insulation, and excellent physical properties. The most important thing is that the source of raw materials is wide and the price is low. [0003] And the present weak point of the sole of PVC preparation is that low temperature resistance is not enough, and in extreme environment, still can't satisfy people's requirement. Contents of the invention [0004] Purpose of the invention: the purpose of the invention is to provide a low temperature resistant PVC sole...
