Abstract

The invention discloses a preparation method of a nano antibacterial PPR cold and hot water pipe. The preparation method comprises the following steps that raw materials are taken according to a conventional method and mixed by a mixing device (24), and then a PPR pipe body is prepared according to the conventional steps. The structural design is reasonable, the operation is simple, the mixing isconvenient and rapid, and simultaneously the prepared PPR cold and hot water pipe has antibacterial function, the water quality is improved and the safety of drinking water is ensured.

Description

technical field [0001] The invention relates to the technical field of PPR pipes, in particular to a method for preparing a nanometer antibacterial PPR cold and hot water pipe and a preparation method thereof. Background technique [0002] PPR (polypropylenerandom), also known as random copolymerized polypropylene (PPR), has good toughness, high strength, excellent processing performance, good creep resistance at higher temperatures, and has the unique high transparency of random copolymerized polypropylene. , can be widely used in the production of pipes, sheets, daily necessities, packaging materials, household appliance parts and various films. [0003] PP-R pipe is also called three-type polypropylene pipe and random copolymerized polypropylene. Random copolymerized polypropylene can be extruded into pipes or injection molded into pipe fittings. Ethylene is the most commonly used monomer, which causes changes in the physical properties of polypropylene. Compared with p...
