Abstract

The invention discloses a corrugated pipe containing sillimanite. The corrugated pipe is characterized by being prepared from the raw materials in parts by weight: 75-80 parts of PVC (Polyvinyl Chloride) resin, 3-4 parts of polybenzimidazole fiber, 0.6-2 parts of black sand, 0.7-1 part of permethrin, 1-2 parts of boric acid, 2-3 parts of poly (butyl acrylate), 0.3-0.5 part of sodium carboxymethylcellulose, 0.1-0.3 part of butylcellosolve, 2-3 parts of ethylene distearamide, 2-4 parts of vermiculite powder, 1-2 parts of calcium aluminate and 6-10 parts of composite filler. With the adoption of the corrugated pipe, a sample is smooth without a fracture, the two walls of the sample are not disconnected, the inner and outer walls are free of reversed bending, the construction is rapid, the transportation is convenient, and the service life is long when the corrugated pipe is buried in the ground.

Description

technical field [0001] The invention mainly relates to a pipe material, in particular to a corrugated pipe containing sillimanite. 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 bellows containing sillimanite. [0004] The present invention is achieved thro...
