Problems solved by technology

Disadvantages: heavy weight, easy to spit frost (a quality problem), not easy to corrode (environmental protection problem)
Disadvantages: strong water absorption, easy to turn yellow, easy to break, poor elongation, not resistant to water, easy to rot at the bottom
Disadvantages: easy to absorb water, not easy to corrode, not conducive to environmental protection, easy to get dirty
PVC material is also widely used in shoe sole materials, but its strength is poor in all aspects. Therefore, it is necessary to improve and enhance the performance of PVC shoe sole materials

Abstract

The invention discloses an acid-alkali-resistant PVC sole material used for a workshop and a preparation method thereof. The sole material is prepared from 12-20 parts of PVC, 4-10 parts of polyurethane, 3-8 parts of polycarbosilane, 6-12 parts of saturated hydroxyl polyester resin, 3-8 parts of polyketone resin, 5-10 parts of polypropylene glycol di-acrylic ester, 0.5-2 parts of a DL-414 aluminate coupling agent, 2-5 parts of barium metasilicate, 2-7 parts of silicon carbide and 3-6 parts of boron nitride. The preparation method includes the following steps that 1, ball milling is conducted on the barium metasilicate, the silicon carbide and the boron nitride; 2, the PVC, the polyurethane, the polycarbosilane, the saturated hydroxyl polyester resin, the polyketone resin, the polypropylene glycol di-acrylic ester and the DL-414 aluminate coupling agent are taken and mixed; then, the barium metasilicate, the silicon carbide and the boron nitride obtained after ball milling are added and mixed; 3, a twin-screw extruder is adopted for extrusion and pelleting, and the acid-alkali-resistant PVC sole material used for the workshop is obtained.

Description

technical field [0001] The invention belongs to the field of shoe materials, and in particular relates to an acid and alkali-resistant PVC shoe sole material for industrial workshops and a preparation method thereof. technical background [0002] There are many types of sole materials, including rubber, PU, ​​EVA, PVC and other materials, among which rubber is used for the outsole of various sports shoes. Advantages: good wear resistance, non-slip, elastic, not easy to break, good softness, good extensibility, stable shrinkage, good hardness, good bendability. Disadvantages: heavy weight, easy to spit frost (a quality problem), not easy to corrode (environmental protection problem). PU is a polymer polyurethane synthetic material. It is often used in the midsole of basketball and tennis shoes, and can also be directly used in the outsole of casual shoes. Advantages: high density, high hardness, wear resistance, good elasticity, good oxidation resistance, easy to corrode, g...
