Anti-corrosion superfine fully-vulcanized powdered rubber-polyvinyl chloride composite water pipe and preparation method thereof

Abstract

The invention discloses an anti-corrosion superfine fully-vulcanized powdered rubber-polyvinyl chloride composite water pipe. The composite 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 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, 1.2-1.5 parts of LCP microspheres, 0.8-0.9 part of trichloropropylphosphate, 0.8-1 part of nano-iron oxide, 1.3-1.5 parts of bamboo charcoal micropowder, 2.6-2.8 parts of dodecafluoroheptyl-propyl-trimethoxysilane, 60-70 parts of ethyl alcohol and 15-16 parts of ammonia water. Accordingly, nano-iron oxide is uniformly dispersed in PVC by mixing nano-iron oxide with the bamboo charcoal micropowder, so that the corrosion resistance of the water pipe is improved, and by adding trichloropropylphosphate, the cohesiveness and the flame retardance of the bamboo charcoal micropowder and PVC are improved.

Description

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

Problems solved by technology

[0003] The water pipe obtained through this research has good strength and toughness, but the rubber is easy to corrode and age, and its heat resistance is poor, which affects the service life of the water pipe and needs to be improved. In addition, the toughness of the water pipe needs to be improved according to changes in the environment and production progress , antibacterial, corrosion resistance, mute performance, elasticity, environmental protection, wear resistance, antistatic, tensile strength, antifouling, radiation resistance, flame retardant and other properties
