Problems solved by technology

At present, a large number of galvanized pipes are still used in the application of pipeline facilities in urban water supply systems, and some projects are still using traditional pipes such as cement pipes and cast iron pipes. These pipes have many shortcomings such as easy corrosion, easy pollution, and easy leakage. It is the general trend that pipelines replace traditional pipelines
The rise of plastic pipes has brought hope to people, but plastic pipes have the disadvantage of poor impact resistance, and corresponding measures need to be taken to increase impact resistance

Embodiment Construction

[0006] specific implementation plan

[0007] The invention provides a high-impact polyvinyl chloride pressure pipe, which uses the following materials: PVC resin, heat stabilizer, lubricant, impact modifier, filler, and colorant.

[0008] The PVC resin is SG-5 type resin.

[0009] The heat stabilizer is a rare earth calcium zinc composite stabilizer or a uracil organic stabilizer.

[0010] The lubricant is a mixture of two or more of polyethylene wax, paraffin wax and Fischer-Tropsch wax.

[0011] The impact modifier is a mixture of one or more of impact-resistant ACR, MBS or ABS and PMMA organic rigid particles.

[0012] The filler adopts nano calcium carbonate surface-treated with stearic acid.

[0013] The colorant is titanium dioxide.

[0014] 100 parts by weight of PVC resin, 1.5-4.0 parts of heat stabilizer, 0.4-1.2 parts of lubricant, 6-12 parts of impact modifier, 0-5 parts of filler, 2-3 parts of colorant, heat After mixing and cold mixing, it is made into pipes ...

Abstract

The invention relates to a polyvinyl chloride pressure tube with high impact resistance. The pressure tube comprises 100 portions of PVC resin, 1.5 to 4.0 portions of thermal stabilizing agent, 0.4 to 1.2 portions of lubricant, 6 to 12 portions of impact modifier, 0 to 5 portions of filler and 2 to 3 portions of colorant according to weight unit. Compared with a common PVC-U tube material, the polyvinyl chloride pressure tube keeps high strength of the PVC-U tube material and greatly improves toughness and impact resistance of the tube material.

Description

technical field [0001] The invention relates to a polyvinyl chloride pipe, in particular to a high-impact polyvinyl chloride pressure pipe. Background technique [0002] Pressure pipes are indispensable facilities in urban water supply systems. At present, a large number of galvanized pipes are still used in the application of pipeline facilities in urban water supply systems, and some projects are still using traditional pipes such as cement pipes and cast iron pipes. These pipes have many shortcomings such as easy corrosion, easy pollution, and easy leakage. It is the general trend for pipelines to replace traditional pipelines. The rise of plastic pipes has brought hope to people. However, plastic pipes have the disadvantage of poor impact resistance, and corresponding measures need to be taken to increase impact resistance. Contents of the invention [0003] The invention is used to provide a polyvinyl chloride pressure pipe which not only maintains the high strength...
