Abstract

The invention discloses an overpressure resistant PVC tubing, which is composed of the following components by weight: 50-70 parts of PVC resin, 3-5 parts of plasticizer, 6-10 parts of lithopone, 10-12 parts of calcium carbonate, 3-5 parts of cadmium stearate, 5-10 parts of impact resistance agent, 3-6 parts of aluminium hydroxide, and 5-10 parts of synthesized paraffin. The impact resistance tubing has the advantages of good toughness and shock resistance, chemical corrosion resistance, improved tensile strength and fracture elongation rate, good toughness without water leakage, water seepage and rupture, and MBS resin is added into the PVC for promoting plasticizing, and enhancing inorganic substance dispersion and processing fluidity of PVC melt, and improving low temperature impact strength of the product.

Description

technical field [0001] The invention relates to a pipe material, in particular to a pressure-resistant PVC pipe material. Background technique [0002] The impact strength of rigid polyvinyl chloride products is not high. At present, it is mainly added by adding CPE (chlorinated polyethylene), MBS (butadiene and styrene, methyl methacrylate copolymer) or high impact ACR (acrylate copolymer) to improve the impact strength of the product. However, the impact resistance of CPE products is limited; high-impact ACR and MBS resins can maintain the product [0003] However, simply adding MBS or ACR cannot meet the requirements of high strength and high impact resistance of PVC-M pipes and fittings. Contents of the invention [0004] Aiming at the deficiencies in the existing technology, the technical problem to be solved by the present invention is to provide a low-cost, high-strength and toughness, high-impact resistance, which can effectively solve the problem of low impa...
