Problems solved by technology

[0004] The water pipe is made of sanitary polyvinyl chloride (PVC) resin as the main raw material, adding an appropriate amount of stabilizer, lubricant, filler, color enhancer, etc., extruded by a plastic extruder and injected by an injection molding machine, through cooling, curing, Sizing, inspection, packaging and other processes to complete the production of pipes and fittings. As for water pipes in the air, they have strong oxidation and corrosion resistance. However, in many cases, water pipes are buried by cement and other corrosive objects. Long-term, easy corroded

Abstract

The invention relates to a reinforced anti-corrosion rubber sleeve for a water pipe wall and a preparation method thereof. The rubber sleeve comprises a bottom film, wherein a bottom-layer glue, a middle-layer fiber net and a surface-layer glue are arranged on the bottom film; the water pipe wall is wrapped with the bottom film, then is coated with the bottom-layer glue, then the middle-layer fiber net and finally the surface-layer glue. The rubber sleeve which wraps the exterior of the water pipe is used for protecting the water pipe. In the rubber sleeve prepared according to the method, the film is arranged at the bottom, so that the reinforcing and anti-corrosion effects are achieved while the glue is prevented from being in contact with the pipe wall; the water pipe can be conveniently taken out; the anti-corrosion property is strong; the fiber net is arranged in the middle layer; the overall strength is enhanced; the burst is reduced to a certain extent; the high temperature resistance and the cold resistance are enhanced.

Description

[0001] Technical field: [0002] The invention relates to a rubber sleeve, in particular to a water pipe wall reinforced anti-corrosion rubber sleeve and a preparation method thereof. [0003] Background technique: [0004] The water pipe is made of sanitary polyvinyl chloride (PVC) resin as the main raw material, adding an appropriate amount of stabilizer, lubricant, filler, color enhancer, etc., extruded by a plastic extruder and injected by an injection molding machine, through cooling, curing, Sizing, inspection, packaging and other processes to complete the production of pipes and fittings. As for water pipes in the air, they have strong oxidation and corrosion resistance. However, in many cases, water pipes are buried by cement and other corrosive objects. Long-term, easy Corroded. [0005] Invention content: [0006] The technical problem to be solved by the present invention is to overcome the defects of the prior art, and provide a water pipe wall reinforced anti-cor...
