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 high-pressure PVC (polyvinyl chloride) hose. The high-pressure PVC hose is characterized by comprising the following raw materials in parts by weight: 70-76 parts of polyvinyl chloride, 1-2 parts of 4, 4'- diphenylmethane diisocyanate, 6-8 parts of stearate, 2-3 parts of powdered butyronitrile, 2-3 parts of hexamethylphosphoric triamide, 2-4 parts of epoxy soybean oil, 2-3 parts of trimethylolpropane, 1-2 parts of aluminium oxide, 3-5 parts of fast extruding carbon black, 3-4 parts of polytetrafluoroethylene, 0.8-2 parts of zirconium silicate, 1-2 parts of tetramethoxy methyl glycoluril and 6-10 parts of composite filler. The high-pressure PVC hose has very high oxidation resistance and corrosion resistance; the added zirconium silicate and powdered butyronitrile are capable of greatly improving the physical properties of the high-pressure PVC hose, and the pressure-resistant property of the high-pressure PVC hose; the high-pressure PVC hose is low in cost.

Description

technical field [0001] The invention mainly relates to a pipe material, in particular to a high-pressure PVC hose. 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, natural gas and liquefi...
