Abstract

The invention discloses a high-strength and hydraulic-pressure-resistant PVC (polyvinyl alcohol) pipe and a preparation method thereof. The pipe is prepared from raw materials in parts by weight as follows: 80-100 parts of PVC resin, 3-5 parts of imarcaptoacetate dioctyltin, 0.8-1.2 parts of stearic acid, 1-4 parts of paraffin, 1-2 parts of chlorinated polyethylene, 5-8 parts of mica powder, 3-4 parts of diatomaceous earth, 1-2 parts of carbon black, 3-5 parts of construction waste recycled aggregates, 2-4 parts of nitrile rubber, 5-7 parts of nano calcium carbonate, 2-4 parts of hydroxyethyl methylacrylate and 1.2-1.6 parts of benzoyl peroxide. The high-strength and hydraulic-pressure-resistant PVC pipe has good pipe pressure bearing performance and aging resistance, is high in strength and cannot be broken easily.

Description

technical field [0001] The invention relates to the technical field of PVC pipes, in particular to a high-strength hydraulic-resistant PVC pipe and a preparation method thereof. Background technique [0002] In agricultural irrigation, PVC pipes are widely used, but PVC pipes often have the phenomenon that the pressure bearing performance and impact performance cannot meet the standards at the same time. The PVC pipes produced by most enterprises are either qualified for pressure bearing but unqualified for drop hammer impact performance, or qualified for drop hammer impact performance but unqualified for pressure bearing performance. Especially for pipes with pipe diameters below 50mm. The failure of these two indicators of hard PVC pipes has caused the phenomenon of "pipe burst" in many PVC pipes used in water-saving projects. The unqualified drop hammer impact performance of PVC pipes will cause the pipes to break due to the scraping and grinding of stones and sand duri...
