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

Abstract

The invention discloses an antistatic superfine fully-vulcanized powdered rubber and polyvinyl chloride composite water pipe. The water pipe is prepared from raw materials in parts by weight as follows: 29-30 parts of superfine fully-vulcanized powdered rubber, 68-70 parts of PVC SG-3, 2-2.3 parts of zinc oxide nanowires, 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 parts of ammonium persulfate, 1.6-1.8 parts of barium sulfate, 1.3-1.5 parts of nano indium, 0.7-0.9 parts of nanocarbon sol, 2.6-2.8 parts of dodecafluoroheptylpropyltrimethoxysilane, 60-70 parts of ethanol and 15-16 parts of ammonia water. Barium sulfate and nanocarbon sol are mixed and ground uniformly, nano indium is added, nanocarbon sol is bonded on the surface of barium sulfate, the surface is covered with nano indium, the bonding property of barium sulfate is improved, the antistatic property and the wear resistance of the water pipe are improved through combined use of barium sulfate, nano indium and nanocarbon sol, and the silence effect is also improved.

Description

technical field [0001] The invention relates to the technical field of PVC water pipes, in particular to an antistatic superfine fully vulcanized powder rubber polyvinyl chloride composite water pipe and a preparation method thereof. Background technique [0002] Plastic pipes 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 blended modified PVC-U...

AI Technical Summary

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
