Problems solved by technology

However, conventional PPR pipes do not have self-cleaning and sterilizing properties. During use, the interior of the pipe will become a breeding ground for secondary pollutants and bacteria, affecting water quality and health.
In addition, in order to improve the performance of conventional PPR pipes, various modified additives are used in materials. These substances may be dissolved with running water during use and affect the quality of drinking water.

Abstract

The invention relates to the technical field of water delivery pipelines, in particular to a novel antibacterial PPR composite water delivery pipe with the good weatherability. The composite water delivery pipe comprises an antibacterial inner layer, a structure layer and a weatherproof outer layer from the inside to outside of the pipe, wherein, the antibacterial inner layer is prepared from rawmaterials, in parts by mass: a PPR raw material, a nano silver antibacterial agent and an agion antibacterial additive; the structure layer is prepared from raw materials: the PPR raw material, blockco-polypropylene PPB, polyisobutene, nylon, paroline, an initiator and an antioxidant; and the weatherproof outer layer is prepared from polypropylene particles, polyethylene particles, tetraethoxy titanium, the initiator, stearic acid, a catalyst, the antioxidant, an ultraviolet absorbent and color masterbatch. Compared with a common PPR water delivery pipe, the novel water delivery pipe has thebetter weatherability, higher compressive strength, and better antibacterial effect, meanwhile, has the advantages that no toxic and harmful substances are dissolved out in the using process, and is very safe and reliable.

Description

technical field [0001] The invention relates to the technical field of water delivery pipes, in particular to a novel antibacterial PPR composite water delivery pipe with good weather resistance. Background technique [0002] Water pipes are transportation pipes that transport water resources from water plants to water users. There are three types of water pipes currently in use. The first type is metal pipes, such as hot-dip cast iron pipes with plastic lining, copper pipes, and stainless steel pipes; The second category is plastic composite metal pipes, such as plastic composite steel pipes, aluminum-plastic composite pipes, etc.; the third category is plastic pipes, such as PB pipes and PPR pipes. Each type of pipe has its own advantages and disadvantages. Among these types of pipes, the most popular one is the PPR plastic pipe. [0003] PPR plastic pipe is made of non-toxic, pressure-resistant, light-weight random copolymerized polypropylene material. This kind of pipe ...
