Abstract

The invention discloses a high heat-resistant anti-aging CPVC power cable protection tube. The tube comprises the following raw materials, in parts by weight: 450-550 parts of CPVC, 200-300 parts of PVC, 150-200 parts of calcium powder, 30-50 parts of a toughening agent, 3-15 parts of nitrile rubber, 20-30 parts of a stabilizer, 10-20 parts of a flame retardant, 1-5 parts of stearic acid, and 12-18 parts of paraffin. The high heat-resistance anti-aging CPVC power cable protection tube provided by the invention has a temperature resistant to heat deformation of 98 DEG C or more, has excellent high-temperature resistance, and can adapt to high-temperature harsh environments; the flame retardant performance reaches a FV-0 level; the tube has the characteristics of good flexibility, uneasy breakage and aging, long service life, no radiation pollution and a light weight; and in addition, a preparation method provided by the invention is simple and controllable, and the production is easy tooperate.

Description

technical field [0001] The invention belongs to the technical field of power cable protection tubes, and in particular relates to a high heat-resistant and anti-aging CPVC power cable protection tube and a preparation method thereof. Background technique [0002] CPVC power pipes are usually used as cable protection pipes with excellent corrosion resistance. In recent years, they have been widely used in steel, metallurgy, petroleum, chemical, fertilizer, dye, pharmaceutical, electric power, environmental protection and sewage treatment industries. It has the characteristics of good performance, good insulation performance, no pollution, and convenient construction. It is an ideal substitute for traditional asbestos cable pipes and ordinary PVC pipes. CPVC power pipe is extruded with CPVC (chlorinated polyethylene resin) as the main raw material. CPVC resin is obtained by chlorination and modification of PVC (polyvinyl chloride) resin. After PVC resin is chlorinated, the irr...
