Problems solved by technology

The disadvantage is that the equipment is not as good as steel pipes. During construction, special attention should be paid to the safe distance of thermal heating, and it cannot be exposed to sunlight in the air, and it is sensitive to chemicals to prevent damage caused by leakage of sewage pipes.

Abstract

The invention discloses a low-temperature impact-resistant tubular product, which is characterized by being composed of the following raw materials in parts by weight: 70-76 parts of polyethylene GF7750, 4-6 parts of drying oil alkyd resin, 2-3 parts of ethylene-octene copolymer, 1-2 parts of diacetone alcohol, 0.7-2 parts of triclosan, 2-3 parts of polyimide, 3-4 parts of di(2-ethylhexyl)-epoxy tetrahydrophthalate, 2-3 parts of carbon fibers, 3-4 parts of illite powder, 2-3 parts of aluminum stearate and 5-7 parts of composite filler. The PE pipe provided by the invention is prepared from recycled polyethylene material so that the production cost is reduced and resources are saved; the tubular product provided by the invention has excellent low-temperature impact resistance; for construction in winter, pipe breakage is avoided; the low-temperature impact-resistant tubular product also has high shear strength and excellent scratch resistance.

Description

technical field [0001] The invention mainly relates to a pipe material, in particular to a low-temperature impact-resistant pipe material. 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. [0003] PE pipes include medium-density polyethylene pipes and high-density polyethylene pipes. The former is suitable for transporting gaseous artificial gas, na...
