Abstract

The invention provides an environment-friendly water-supply hose with antibacterial function, which comprises materials of PVC resin, a plasticizing agent, a heat stabilizer, an inorganic-organic composite antibacterial agent and a lubricating agent, wherein the average degree of polymerization of the PVC resin is between 900 and 1,300; the water-supply hose comprises the following components in proportion by mass: 100 portions of the PVC resin, 40 to 70 portions of the plasticizing agent, 2 to 4 portions of the heat stabilizer, 0.1 to 0.4 portion of the inorganic-organic composite antibacterial agent, 0.2 to 0.6 portion of the lubricating agent; and the inorganic-organic composite antibacterial agent comprises the following components in portion by mass: 90 to 120 portions of tourmaline powder, 20 to 35 portions of zinc oxide, 10 to 20 portions of nano silver, 45 to 55 portions of zeolite powder, and 10 to 15 portions of 2,4,4'-trichloro-2'-hydroxy diphenyl ether. The environment-friendly water-supply hose can effectively inhibit the growth of microorganisms, has good antibacterial effect, accords with the safety standard requirements, and has excellent environmental protection performance.

Description

technical field [0001] The invention relates to the field of plastic pipes for water supply pipe networks, in particular to a water supply hose. Background technique [0002] When the content of organic matter in drinking water is high, even if the residual chlorine remains high when the tap water leaves the factory, dozens of bacteria can still be detected in the water supply pipeline, mainly heterotrophic bacteria based on organic matter. As the water storage time in the water pipe prolongs, the turbidity and heterotrophic bacteria in the water body in the pipe will increase. When the organic matter in the water body is consumed, the bacteria will actively migrate to the inner wall of the pipe to survive, and there is plasticization in the inner wall of the water pipe. Bacteria can continue to multiply in large numbers, and the long-term growth of bacteria in the pipe wall forms a biofilm, which induces corrosion and scaling of the pipe wall. The aging and shedding of the ...
