Abstract

The invention discloses a power cable protective pipe. The protective pipe is characterized by comprising the following raw materials in parts by weight: 80-86 parts of PVC (polyvinyl chloride) resin, 0.4-1 part of triclocarban, 0.5-1 part of potassium perfluorobutane sulfonate, 0.6-1 part of 2,4,4'-trichlorine-2'-phenoxyphenol, 1-2 parts of succinic acid, 2-3 parts of sodium fluoborate, 2-3 parts of EVA (ethylene-vinyl acetate) resin, 2-3 parts of ethylhexyl methacrylate, 2-3 parts of bamboo carbon powder, 0.5-1 part of zinc borate, 2-3 parts of graphite powder, 2-3 parts of bisphenol A phosphate, 1-2 parts of aminopropyltriethoxysilane, and 10-15 parts of composite filler. The pipe is particularly suitable for a protective pipe of a power cable, has excellent performances of impact resistance, abrasion resistance, ring stiffness and the like, and is strong in comprehensive performance and good in stability.

Description

technical field [0001] The invention mainly relates to a pipe material, in particular to a power cable protection pipe. Background technique [0002] PVC pipe (UPVC pipe) Rigid polyvinyl chloride pipe is made of polyvinyl chloride resin, stabilizer, lubricant, etc., and is extruded by hot pressing. It is the earliest plastic pipe that has been developed and applied. UPVC pipe has strong corrosion resistance, easy bonding, low price, and hard texture. However, due to the leakage of UPVC monomer and additives, it is only suitable for water supply systems with a delivery temperature not exceeding 45°C. Plastic piping is used in applications for conveying potable water, waste water, chemicals, heating and cooling fluids, food, ultrapure liquids, slurries, gases, compressed air and vacuum systems. Contents of the invention [0003] The object of the present invention is to provide a power cable protection tube. [0004] The present invention is achieved through the follow...
