Problems solved by technology

CPVC cable protection pipe replaces the disadvantages of poor ring stiffness of traditional UPVC double-wall corrugated pipe, PE plastic pipe heat resistance, flame retardancy, and poor ring stiffness, which will be an inevitable trend of future development. Although the existing CPVC cable protection pipe has relatively high High compressive strength, but its high temperature resistance, corrosion resistance, flame retardancy and other properties still cannot meet the needs of the work

Abstract

The invention relates to the technical field of CPVC cable protection pipes, in particular to a flame-retardant CPVC cable protection pipe. The protection pipe is prepared from the following raw materials in parts by mass: 36-38 parts of PVC resin, 80-83 parts of CPVC resin, 10-14 parts of light calcium carbonate, 10-12 parts of silicone rubber, 8-10 parts of ceramic powder, 6-8 parts of an anti-aging agent, 6-8 parts of an antioxidant, 4-6 parts of a heat-resistant agent, 8.1-8.5 parts of a compound stabilizer, 3.5-3.8 parts of an ACR impact modifier, 3.5-4.5 parts of a CPE impact modifier, 0.35-0.65 part of PE wax, 7-11 parts of MBS resin and 0.55-0.75 part of paraffin. Through interaction of the silicone rubber and the ceramic powder, thermal contact resistance generated between the surface of a heat source and an external contact surface is reduced, and the effect of conducting heat is achieved; meanwhile, the insulativity, the extensibility and the heat temperature resistance of the pipeline are improved, and the impact strength, the tensile strength and the bending strength are improved by adding the ACR impact modifier and the CPE impact modifier; and the anti-aging agent, the antioxidant, the heat-resistant agent and the compound stabilizer improve the oxidation resistance, the heat resistance and the stability of the pipeline respectively.

Description

technical field [0001] The invention relates to the technical field of CPVC cable protection tubes, in particular to a flame-retardant CPVC cable protection tube. Background technique [0002] With the rapid development of the country's economic development, urban construction is increasingly updated, and power cables have entered from overhead to buried. CPVC cable protection pipe has high strength, good flexibility, high temperature resistance, high pressure resistance, corrosion resistance, flame retardancy, and good insulation performance. , no pollution, not easy to age, light weight and other characteristics, and can also prevent the influence of thermal expansion and contraction. With the use of flared sockets, the outside of the pipe does not need to be reinforced with other materials during construction, and the construction is carried out section by section, which saves labor, and the construction is convenient and fast. CPVC cable protection pipe replaces the dis...
