Abstract

The invention discloses a mute 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, 2-2.3 parts of wood shavings, 10-12 parts of a 9-10% nitric acid solution, 10-12 parts of a urea saturated solution, 2-2.5 parts of glycerin monostearate, 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, wood shavings are swollen and filled with glycerin monostearate, so that the compatibility of wood shavings and PVC is improved, and the toughness and mute effect of the water pipe are improved.

Description

technical field [0001] The invention relates to the technical field of PVC water pipes, in particular to a quiet 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 rubber bl...
