Abstract

The invention discloses a pressure-resistant PVC water supply pipe material and a preparation method thereof. The wear-resistant PVC water supply pipe material is prepared from the following raw materials in parts by weight: 45-65 parts of SG-3 type PVC resin, 20-30 parts of medium density polyethylene, 12-24 parts of polylactic acid, 10-15 parts of 1,2-polybutadiene, 3-5 parts of ethoxy ethylene bis stearamide, 2-4 parts of tribehenin, 1.5-2.5 parts of montanic acid zinc, 1-2 parts of tribasic lead sulfate, 1-2 parts of dibutyltin bis(isocaprylic acid sulfydryl ethyl ester), 0.5-1 part of 3-methyl 3-aminocrotonate, 1.5-2.5 parts of calcium acetylacetonate, 4-6 parts of white oil, 15-25 parts of nano-hydroxyapatite, 10-15 parts of aluminium borate whisker, 5-10 parts of dibromoneopentyl glycol, 14-26 parts of magnesium hydrate, 15-20 parts of filling master batch, 8-16 parts of acetyl tributyl citrate, 2-3 parts of 4,4'-dihydroxybiphenyl and 1-2 parts of 2,6-butylated hydroxytoluene. The PVC pipe material is good in pressure-resistant property and high in mechanical strength, has excellent water pressure resistant strength, external pressure resistant strength and impact resistant strength, has low possibility of water leakage, water seepage and fracture, is long in service life, is suitable for water supplying piping engineering under various conditions, and is 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 pressure-resistant PVC water supply pipe material and a preparation method thereof. Background technique [0002] PVC pipes are widely used in various water supply projects because of their good mechanical properties, good insulation properties, strong corrosion resistance, long service life, light weight, easy transportation, and installation. In recent years, with the rapid development of science and technology and the continuous improvement of people's living standards, the performance requirements of PVC water supply pipes are getting higher and higher. The PVC water supply pipes currently on the market have poor pressure resistance and are prone to water leakage, water seepage, and rupture. Such problems greatly reduce the service life of PVC pipes and limit its scope of application. Therefore, it is urgent to develop a pressure-resistant PVC water su...
