Abstract

The invention discloses a high strength and high toughness PVC pipe and a preparation method thereof. The pipe is prepared from the following raw materials by weight part: 65-85 of SG-3 type PVC, 15-20 of bisphenol A type cyanate ester resin, 2-4 of lead sulfide, 10-15 of di-isononyl-cyclohexane-1,2-dicarboxylate, 14-18 of aluminum borate whisker, 16-22 of polyetherimide, 10-15 of chloroprene rubber, 15-20 of attapulgite, 12-16 of barium titanate, 5-10 of pumice powder, 10-15 of glycerol triacetylricinoleate, 3-5 of docosanamide, 4-6 of peat wax, 1.5-2.5 of di-n-octyltin Dilaurate, 1-2 of zinc p-toluene sulfinate, 2-3 of tri(nonylphenyl) phosphate, 1-2 of 4, 4'-thiobis(6-tert-butyl-3-methyl phenol), and 4.5-6.5 of an assistant. The PVC pipe prepared by the invention has very high tensile strength and toughness, has significantly improved pressure resistance, and has good aging resistance, wear resistance, corrosion resistance and other properties. With the characteristics of simple processing and low cost, the prepared PVC pipe has large market competitiveness.

Description

technical field [0001] The invention relates to a PVC pipe material and a preparation method thereof, in particular to a high-strength and high-toughness PVC pipe material and a preparation method thereof. Background technique [0002] Due to its excellent chemical stability, excellent electrical insulation, good flexibility and colorability, PVC pipes can be used to replace rubber pipes and polyethylene pipes to transport liquids, as well as cable sleeves and wire insulation pipes etc., are widely used. However, with the rapid development of science and technology, the performance requirements for PVC pipes are getting higher and higher. At present, the PVC pipes on the market have the disadvantages of low tensile strength and poor toughness, which lead to poor pressure resistance of the pipes, which greatly limits its application range. Contents of the invention [0003] The object of the present invention is to provide a high-strength and high-toughness PVC pipe and a...
