Abstract

The invention discloses an anti-microbial superfine fully-vulcanized powdered rubber and polyvinyl chloride composite water pipe. The water pipe is prepared from, by weight, 29-30 parts of superfine fully-vulcanized powdered rubber, 68-70 parts of PVCSG-3, 2-2.3 parts of zinc oxide nano-wires, 3-3.2 parts of cerium nitrate, 70-80 parts of deionized water, 1.6-1.8 parts of butyl acrylate, 0.2-0.3 part of ammonium persulphate, 2.3-2.5 parts of graphene oxide, 0.8-1 part of nano-cuprous oxide, 0.8-1 part of asphalt, 2.6-2.8 parts of dodecafluoroheptyl-propyl-trimethoxysilane, 60-70 parts of ethyl alcohol and 15-16 parts of ammonium hydroxide. According to the water pipe, graphene oxide and nano-cuprous oxide are mixed and stirred for 20-30 min at 2-2.5 MPa, so that the surface of graphene oxide is loaded with nano-cuprous oxide, and a good anti-microbial effect is achieved; then, asphalt is added, so that the cohesiveness of graphene oxide, nano-cuprous oxide and PVC is improved.

Description

technical field [0001] The invention relates to the technical field of PVC water pipes, in particular to an antibacterial ultrafine fully vulcanized powder rubber polyvinyl chloride composite water pipe and a preparation method thereof. Background technique [0002] Plastic pipes for pressure water supply should have both high strength and high toughness. Rigid polyvinyl chloride (PVC-U) water supply pipes have insufficient toughness and are easy to burst under the action of external conditions. Improving the mechanical properties of PVC-U materials is an effective way to increase the service life of products. The article "Research on the Modification of Rigid Polyvinyl Chloride by Ultrafine Fully Vulcanized Powder Rubber" aims at this practical problem, starting from the basic idea of ​​toughening and enhancing the performance of PVC-U materials, for the first time using high-type resin to extrude PVC-U water supply For the pipe material, fully vulcanized ultrafine powder ...
