Abstract

The invention relates to the technical field of cable protection tubes. Particularly, the invention relates to an improved CPVC power tube comprising the following raw materials in parts by weight: 100 to 120 parts of chlorinated polyvinyl chloride, 5 to 6 parts of graphene A, 8 to 9 parts of carbon black, 6 to 8 parts of a coupling agent, 11 to 13 parts of a flexibilizer, 3 to 5 parts of a compatibilizer, 4 to 6 parts of a composite lubricant, 0.5 to 2 parts of an antioxidant, 0.5 to 1.5 parts of nano calcium carbonate, 0.5 to 1 part of titanium dioxide and 5 to 10 parts of a flame-retardantcomposite material. The melt flow rate, the tensile strength, the elongation at break and the bending strength of the improved CPVC power tube prepared by the method are relatively reduced; the cableprotection tube composed of the material has the characteristics of strong corrosion resistance, good electrical insulation, high mechanical strength, small friction coefficient, heat resistance, coldresistance, long service life and the like.

Description

technical field [0001] The invention relates to the technical field of cable protection tubes, in particular to an improved CPVC power tube. Background technique [0002] At present, there are two types of cable protection tubes commonly used in the market: MPP tubes and CPVC tubes. Among them, MPP pipes are divided into excavation type and non-excavation type, and MPP non-excavation pipes are also called MPP jacking pipes or tola pipes. MPP pipe is a plastic pipe prepared by using modified polypropylene as the main raw material. CPVC pipe is one of the most conventional power pipes mainly used in the market at present, but with the gradual expansion of its application field and environment, its shortcomings are also It is becoming more and more prominent, such as strength, flame retardancy, electrical insulation, acid and alkali corrosion resistance, oxidation resistance, sliding properties, thermal stability and other comprehensive properties cannot fully adapt to the hig...
