Wear-resistant ultrafine-fully-vulcanized-powdered-rubber polyvinyl-chloride composite water pipe and preparation method thereof

Abstract

The invention discloses a wear-resistant ultrafine-fully-vulcanized-powdered-rubber polyvinyl-chloride composite water pipe. The water pipe is prepared from the following raw materials in parts by weight: 29-30 parts of ultrafine 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 persulfate, 0.7-0.9 part of dimolybdenum sulfide, 1.1-1.3 parts of molybdenum trioxide, 1.3-1.5 parts of nano silicon carbide, 0.1-0.2 part of titanate coupling agent, 2.6-2.8 parts of dodecafluoroheptylpropyl trimethoxysilane, 60-70 parts of ethanol and 15-16 parts of ammonia water. According to the water pipe, by using the nano silicon carbide, the dimolybdenum sulfide and the molybdenum trioxide, the dimolybdenum sulfide has good lubricity and fluidity and is used for promoting the homogeneous dispersion of the nano silicon carbide and the molybdenum trioxide in the water pipe, so that the wear resistance of the water pipe is improved.

Description

technical field [0001] The invention relates to the technical field of PVC water pipes, in particular to a wear-resistant 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 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 ...
