High-antifouling ultrafine-fully-vulcanized-powder-rubber and polyvinyl-chloride composite water pipe and preparing method thereof

Abstract

The invention discloses a high-antifouling ultrafine-fully-vulcanized-powder-rubber and polyvinyl-chloride composite water pipe. The high-antifouling ultrafine-fully-vulcanized-powder-rubber and polyvinyl-chloride composite water pipe is prepared from, by weight, 29-30 parts of ultrafine fully-vulcanized powder rubber, 68-70 parts of PVCSG-3, 2-2.3 parts of zinc oxide nanowires, 3-3.2 parts of cerous nitrate, 70-80 parts of deionized water, 1.6-1.8 parts of butyl acrylate, 0.2-0.3 part of ammonium persulfate, 1.5-1.8 parts of nanosilicon dioxide, 1.3-1.5 parts of nano-porous carbon, 1.5-1.6 parts of aluminum isopropoxide, 6-7 parts of isopropyl alcohol, 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 high-antifouling ultrafine-fully-vulcanized-powder-rubber and polyvinyl-chloride composite water pipe, the nano-porous carbon is modified through the nanosilicon dioxide and the aluminum isopropoxide, the nano-porous carbon is good in adsorption performance, the nanosilicon dioxide and the aluminum isopropoxide are adsorbed to the surface and the interior of the nano-porous carbon, and therefore the antifouling performance, the heat resistance and the aging resistance of the water pipe are improved.

Description

technical field [0001] The invention relates to the technical field of PVC water pipes, in particular to an antifouling high 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 powd...
