Abstract

The invention discloses an anti-fatigue PVC tubular material and a preparation method thereof. The anti-fatigue PVC tubular material is prepared from the following raw materials in parts by weight: 50-70 parts of SG-2 type PVC, 15-25 parts of polyformaldehyde, 4-8 parts of barium fluoride, 3-6 parts of polyamide wax micropowder, 4-8 parts of propolis, 6-12 parts of basic magnesium carbonate, 4.5-6.5 parts of low molecular weight polybutadiene, 17-23 parts of acrylonitrile / EPDM / styrol copolymer, 8-12 parts of dihexyl adipate, 10-15 parts of activated clay, 2-3 parts of p-tert-butyl zinc benzoate, 1-2 parts of calcium naphthenate, 10-15 parts of epoxy acetyl methyl ricinoleate, 1.5-2.5 parts of ethyl p-aminobenzoate, 1-2 parts of 3-(3, 5-ditertiary butyl-4-hydroxy phenyl) methyl propionate and 3-5 parts of addition agent. The PVC tubular material prepared by the invention is excellent in fatigue performance, high in fatigue strength and tensile strength, good in environment resistance and organic solvent resistance, excellent in size stability without crack after being used for a long time, long in service life and wide in application prospect.

Description

technical field [0001] The invention relates to a PVC pipe material and a preparation method thereof, in particular to a fatigue-resistant 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. PVC pipes currently on the market have the disadvantage of poor fatigue resistance, and are prone to cracking after long-term use, which greatly reduces their service life. Contents of the invention [0003] The object of the present invention is to address the deficiencies of the prior art, provide an anti-fatigue PVC pipe and its preparation method,...
