Abstract

The invention discloses a double-wall corrugated pipe. The double-wall corrugated pipe is characterized by comprising the flowing raw materials, by weight, 63 to 70 parts of PVC (Poly Vinyl Chloride) resin, 4 to 6 parts of chlorinated polyethylene, 1 to 2 parts of calcium magnesium powders, 4 to 6 parts of light calcium carbonate, 2 to 3 parts of decabromodiphenylethane, 3 to 4 parts of permethrin, 1 to 2 parts of maleic anhydride, 1 to 2 parts of 4, 4'-methylene diphenyl diisocyanate, 2 to 3 parts of triethylene glycol, 1 to 2 parts of pentaerythritol, 1 to 2 parts of n-salicylanilide and 5 to 10 parts of composite fillers. The double-wall corrugated pipe has the advantages of being excellent in chemical stability, aging resistant performance and environmental stress cracking performance, rapid to construct and easy to maintain.

Description

technical field [0001] The invention mainly relates to a pipe material, in particular to a double-wall corrugated 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 double-wall corrugated pipe. [0004] The present invention is achieved through the following...
