Abstract

The invention discloses a high-performance polyvinyl chloride (PVC) plastic pipe. The high-performance PVC plastic pipe is characterized by comprising the following components in parts by weight: 20-30 parts of PVC resin, 10-20 parts of acrylic rubber, 3-4 parts of heat stabilizer, 5-10 parts of triphenyl phosphate, 5-15 parts of stearic acid, 2-6 parts of fire retardant, 10-15 parts of epoxy butyl oleate, and 10-12 parts of paraffin wax. The high-performance PVC plastic pipe prepared by the invention has excellent characteristics of high strength, good super-toughness, high-temperature resistance, impact resistance and corrosion resistance, and relative low cost; the vicat softening temperature can be up to over 120 DEG C; the problems of low temperature brittleness, impact resistance and the like of the traditional polyvinyl chloride pipe are solved.

Description

technical field [0001] The invention relates to the technical field of plastic pipes, in particular to a high-performance PVC plastic pipe. Background technique [0002] Due to the relatively low strength, relatively poor toughness, poor high temperature resistance, and poor impact resistance of current PVC pipes, when used as power pipes in environments that need to withstand high pressure and high temperature, often due to performance reasons result in a shorter service life. Therefore, a polyvinyl chloride pipe with high strength, high toughness, corrosion resistance, high temperature resistance and relatively low cost has a very important impact on the application of power pipes. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the technical problem to be solved by the present invention is to provide a solution [0004] The polyvinyl chloride pipes of Liguan have relatively low strength, relatively poor toughness, poor high temperat...
