Abstract

The invention discloses an aging-resistant PVC tubular product and a preparation method thereof. The aging-resistant PVC tubular product is prepared from the following raw materials in parts by weight: 100-150 parts of SG-3 PVC, 30-60 parts of an acrylonitrile-styrene-acrylate copolymer, 2-4 parts of triglycidyl isocyanurate, 10-15 parts of titanium dioxide, 15-20 parts of sericite in powder, 25-45 parts of polyether sulfone, 3-6 parts of polytetrafluoroethylene micropowder, 2-3 parts of tribasic aluminum sulfate, 1.5-2.5 parts of a barium cadmium zinc liquid compound stabilizer, 3-5 parts of erucyl amide, 4-7 parts of Fischer Tropsch wax, 1-2 parts of pyrithione zinc, 1-2 parts of bisphenol A phosphate, 5-10 parts of caustic-burned magnesia powder and 3-4 parts of auxiliaries. The PVC tubular product prepared by the preparation method disclosed by the invention not only has excellent ultraviolet aging resistance and mechanical property, but also has good heat resistance, corrosion resistance, wear resistance, impact resistance, environmental stress crack resistance and the like, and is free from deformation and cracking when being exposed to the sun for a long time and durable.

Description

technical field [0001] The invention relates to a PVC pipe material and a preparation method thereof, in particular to an aging-resistant PVC pipe material and a preparation method thereof. Background technique [0002] Due to its light weight, corrosion resistance, high compressive strength, good electrical insulation performance, safety and convenience, PVC pipes are widely used in drainage pipes, water supply pipes, wire pipes, cable sheathing pipes and other fields. Plastic pipes inferior to polyethylene. However, with the rapid development of science and technology, the performance requirements for PVC pipes are getting higher and higher. At present, PVC pipes on the market are prone to aging and cracking under long-term sunlight exposure, which greatly limits their scope of use. Contents of the invention [0003] The object of the present invention is to provide an anti-aging PVC pipe and its preparation method to improve the anti-ultraviolet aging performance of t...
