High impact polychloroethylene pressure tube

[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 ...
