Abstract

The invention discloses an insulation PVC plastic, which is prepared from the following raw materials in parts by weight: 100 to 120 parts of PVC resin, 3 to 5 parts of plasticizing agents, 3 to 5 parts of tougheners, 5 to 8 parts of nano-TiO2, 3 to 4 parts of antioxidants, 15 to 20 parts of filling agents, 3 to 5 parts of carbon black and 2.5 to 3 parts of anti-static agents. The used raw materials have rich sources and low cost. The operation of the method for preparing the PVC elastomer material by using the recipe is simple; the defect that the insulation performance of the PVC plastic inthe prior art cannot reach the use requirements can be well overcome; the insulation PVC plastic is suitable for industrial production.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to an insulating PVC plastic. Background technique [0002] PVC (polyvinyl chloride) is a thermoplastic resin polymerized by vinyl chloride under the action of an initiator. It is a homopolymer of vinyl chloride. Vinyl chloride homopolymer and vinyl chloride copolymer are collectively referred to as vinyl chloride resin. PVC has good mechanical properties, the tensile strength is about 60mpa, and the impact strength is 5-10kj / m 2 , has excellent dielectric properties, but poor stability to light and heat. It will decompose and produce hydrogen chloride when it is above 100°C or after long-term sunlight exposure, and further autocatalytic decomposition will cause discoloration and rapid decline in physical properties. In practical applications, stabilizers must be added to improve the stability to heat and light. In terms of specific applications, according to the main pr...
