PPR water supply pipe tubular product

Abstract

The invention provides a PPR water supply pipe tubular product which comprises the following raw materials: polypropylene resin powder, a polypropylene random copolymer, color master batch, a clay nano composite material, color masterbatch ash and an adjuvant, wherein the adjuvant comprises an antioxidant and crosslinked high density propylene; the color masterbatch ash comprises calcium carbonate and a talcum powder filler; the melt flow rate of the raw materials is 0.2-0.22 g / 10 minutes, the melt density is 0.8-0.96 g / cm3, the oxidation induction time is 110-130 minutes, the tensile strength is 35MPa, and the fracture depth rate is 600%. The PPR water supply pipe tubular product provided by the invention has good anti-pressure ability, flexibility, low-temperature resistance, high-temperature resistance and strong rapid crack propagation breaking tenacity, and the PPR water supply pipe tubular product is better in pressure resistance as a result of the added color masterbatch ash and the clay nano composite material.

Description

technical field [0001] The invention relates to the field of pipes, in particular to a PPR water supply pipe. Background technique [0002] PE material is widely used in the field of water pipe and gas pipe manufacturing because of its high strength, high temperature resistance, good corrosion resistance, and non-toxicity. Because it will not rust and has strong flame retardancy, it is an ideal pipe material for gas pipes; among them, PE material has corrosion resistance and is not easy to breed microorganisms compared with steel pipes. [0003] However, for the water supply pipes used in households, they are generally divided into hot and cold water pipes. The water supply pipes made of common PE materials have poorer heat resistance than PPR materials and cannot be used as cold and hot water pipes; in addition, the water supply pipes made of PE materials Compared with the PPR material, the pressure resistance of the pipe is relatively low, and it is not suitable for the u...

[0003] However, for the water supply pipes used in households, they are generally divided into hot and cold water pipes. The water supply pipes made of common PE materials have poorer heat resistance than PPR materials and cannot be used as cold and hot water pipes; in addition, the water supply pipes made of PE materials Compared with the PPR material, the pressure resistance of the pipe is also relatively low, so it is not suitable for the use of small diameter cold and hot water pipes
