Problems solved by technology

Cold water pipes and hot water pipes in the prior art are difficult to have both high temperature resistance and low temperature resistance. In actual use, some people confuse them because they cannot distinguish the use conditions of cold and hot water pipes. Hot water pipes can be used for cold water pipes. , but cold water pipes cannot be used for hot water pipes. Confusion in use will cause resources to not be allocated optimally, and even threaten people's safety

Abstract

The invention relates to the technical field of plastic product processing, particularly a RRP (polypropylene random) temperature-resistant water pipe. The RRP temperature-resistant water pipe is prepared from the following raw materials in parts by weight: 60-80 parts of carrier resin, 10-30 parts of LLDPE (linear low-density polyethylene), 1-6 parts of butyl rubber and 3-8 parts of special coloring master batch for RRP pipes. The temperature-resistant pipe has the advantages of high toughness, favorable weather resistance, wide application range and high safety, and can be used as both a cold-water pipe and a hot-water pipe.

Description

technical field [0001] The invention relates to a PPR water pipe, in particular to a PPR temperature-resistant water pipe, which belongs to the technical field of plastic product processing. Background technique [0002] Compared with traditional cast iron pipes, galvanized steel pipes, cement pipes and other pipes, PPR pipes have the advantages of energy saving, environmental protection, light weight and high strength, corrosion resistance, smooth inner wall without scaling, easy construction and maintenance, and long service life. Widely used in building water supply and drainage, urban and rural water supply and drainage, city gas, electric power and optical cable sheathing, industrial fluid transportation, agricultural irrigation and other construction, municipal, industrial and agricultural fields. PPR pipe is officially called random copolymer polypropylene pipe, which is the most widely used water supply pipe in home improvement projects. PPR is a random copolymerize...
