Problems solved by technology

[0002] The tracer pipeline is an indispensable pipe material in the current social construction. It prevents the direction of the pipeline from being unknown after the pipeline is laid, and increases the maintenance cost in the later stage; while the existing tracer pipeline is to bury a metal wire in the pipeline, The pipe thus realized can be detected to achieve the purpose of tracing, and the expansion coefficients of the metal wire and the plastic are different, resulting in poor compatibility of the two materials, making it difficult to integrate the pipe and the metal wire; and the metal wire It is easy to be corroded, especially in a humid environment, and most of the pipelines are buried in the wet underground; when the pipeline is buried for a long time, the metal wire will also be corroded, which will cause the pipe to be untraceable
[0003] In addition, in the production process of the existing tr...

Method used

Beneficial effect of the present invention: by magnetic powder is put into non-magnetic color mark machine with co-extrusion extruder extruding on the outer wall of pipeline body under hot-melt state by magnetic powder with materials such as carrier resin as carrier, form tracer line, This makes the pipeline detectable; it solves the problem of complex process and waste of materials caused by setting metal lines in the pipeline through a special process in order to make the pipeline detectable and traceable in the prior art; it solves the problem of metal wire The expansion coefficient of the plastic is different, which leads to poor compatibility of the two materials, so that it is difficult to integrate the pipe and the metal wire; it solves the problem that the metal wire is easily corroded in the prior art, especially when it is wet In an environment where the pipeline is buried for a long time, the metal wire will be corroded, which will lead to the pro...

Abstract

The invention discloses a traceable pipeline. The traceable pipeline comprises a pipeline body and a plurality of tracing lines arranged on the pipeline body; and the pipeline body is composed of mainmaterials and auxiliary materials. According to the traceable pipeline, through the structure that a die head and the pipeline body of a pipeline are not changed, the pipeline can be detected throughdetection equipment by adding magnetic powder, so that the technical problems that the pipeline and a metal wire are difficult to integrate into a whole and the metal wire is easy to corrode caused by embedding a metal tracing strip inside or outside the pipeline in the prior art are avoided, the production process and the on-site connection process of the tracing pipeline are simplified, therefore, the production efficiency and the construction efficiency of the pipeline are improved.

Example Embodiment

[0022] Example 1
[0023] Take 15% of toner, 0.5% of silane coupling agent, 2.5% of PE wax, 2% of oleic acid amide, 60% of EVA resin, 20% of NdFeB magnetic powder, fully mix them, and extrude Machine, drawing machine, granulator and dryer to make masterbatches containing magnetic powder.
[0024] 80% PE/PP material, 3% masterbatch, 1% antioxidant 1010, 1% antioxidant 168, 5% POE, 1% nano calcium carbonate, 0.1% fluorine processing aid Put the mixed material into the co-extrusion extruder, and at the same time put the prepared masterbatch containing magnetic powder into the color marking machine and extrude it with the co-extrusion extruder on the outer wall of the pipe body in a hot melt state to form a tracer line; After the pipe is extruded, it enters the vacuum sizing device for sizing, and the pipe is cooled by the spray device, so that the tracer line and the pipe body are integrated after cooling; the pipe is pulled out by the tractor to make a visible tracked pipeline.
