The heatproof PVC pipe comprises the following raw materials by weight: 80 to 120 parts of polyvinyl chloride, 20 to 40 parts of polyurethane elastomer, 10 to 30 parts of modified white carbon black, 5 to 15 parts of ammonium polyphosphate, 2 to 8 parts of dimethyl methylphosphonate, 1 to 5 parts of red phosphorus, 2 to 6 parts of dioctyl phthalate, 3 to 9 parts of epoxidized soybean oil, 4 to 8 parts of dicumyl peroxide, 1 to 5 parts of 2-phenylimidazole, 2 to 5 parts of zinc oxide, 4 to 6 parts of paraffin, 1 to 3 parts of a stabilizing agent, 2 to 4 parts of calcium stearate, 4 to 8 parts of an antioxidant, 2 to 6 parts of another antioxidant, 1 to 5 parts of polyethylene wax, 2 to 5 parts of titanium dioxide and 4 to 8 parts of inorganic material modified powder. The PVC pipe provided by the invention has excellent impact strength and tensile strength, and good heat resistance.

Description

technical field [0001] The invention relates to a PVC pipe material, in particular to a heat-resistant PVC pipe material with high impact strength and high tensile strength. Background technique [0002] Polyvinyl chloride is one of the earliest plastics developed and one of the five general-purpose plastics. It has a wide range of uses and is relatively cheap. It has excellent mechanical, insulating, non-flammable, corrosion-resistant and wear-resistant properties, and it is cheap and has a wide range of raw materials. Widely used in plastic pipes, plates, rods, plastic doors and windows, insulation materials, wood-like plastics, films, artificial leather, wires and cables, and packaging materials. [0003] PVC pipe has the advantages of light weight, non-conductive, non-flammable, non-combustible, corrosion-resistant, easy to install, not easily corroded by bacteria and fungi, small water flow resistance, high water delivery capacity, etc., but at the same time has poor ...
