Abstract
The invention discloses a PVC (polyvinyl chloride) sheath and a preparation method of the PVC sheath. PVC resin, light calcium carbonate, chlorinated paraffin52, dioctyl phthalate, stearic acid, lubricant 202B, composite stabilizer, bisphenol A, semi-refined paraffin wax, calcium stearate, brightener AC-617A and antimonous oxide are added in parts by weight into a blender to be uniformly blended, and are then subjected to primary plasticization, grain-sized dicing and air cooling, then secondary plasticization, grain-sized dicing and air cooling, and detection and finally packaging. A plurality of kinds of chemical materials are adopted to make the PVC sheath, therefore, the PVC sheath has excellent high-temperature resistance and heat resistance performances, strong compression performance and rigidity and excellent flame retardant property, in addition, the equipment cost is low, and the process is simple.
