Abstract

The invention discloses an anti-aging superfine fully vulcanizated powdered rubber polyvinyl chloride composite water pipe. The composite water pipe is prepared from, by weight, 29-30 parts of superfine fully vulcanizated powdered rubber, 68-70 parts of PVCSG-3, 2-2.3 parts of zinc oxide nanowire, 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, 2-3 parts of expanded graphite, 0.8-1 part of maleic anhydride, 0.8-1 part of lithium chloride sol, 0.5-0.6 part of nano-crystalline cellulose, 2.6-2.8 parts of dodecafluoroheptyl-propyl-trimethoxysilane, 60-70 parts of ethyl alcohol and 15-16 parts of ammonium hydroxide. By mixing expanded graphite, maleic anhydride and lithium chloride sol, the elasticity of expanded graphite is improved. By adding nano-crystalline cellulose, cohesiveness between expanded graphite and PVC is improved. Modified expanded graphite has high thermal conductivity, and the strength, tenacity and 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 anti-aging superfine 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 Ultra-fine 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 ru...
