Abstract
The invention relates to a method for producing a buried pipe with an identification, comprising the following steps of: firstly, mixing a plurality of components and then extruding the mixture through an extruder to form an inner layer; secondly, applying a layer of adhesive to the periphery of the inner layer as a bonding layer through a bonding layer winding machine and a dragger, and adding a colorant; next, spraying an identification marking the information of the pipe on the bonding layer through a coating machine; and finally, arranging a transparent oxygen blocking ethylene-vinyl alcohol copolymer outer layer at the periphery of the bonding layer through an outer layer winding machine and the dragger. The pipe is high in internal strength and good in toughness, and excellent in impact resistance; and the pipe identification is sprayed on the inner layer and the outer layer and protected through a transparent outer layer pipe; and therefore, the pipe is high in practicability and high in exploitativeness.
Description
Technical field
The present invention relates to a kind of manufacturing approach, relate in particular to manufacturing approach with buried tubing of sign in the hyaline layer with buried tubing of sign.
Background technology
In the buried application of non-excavation, require the buried tubing of non-excavation to have high toughness and intensity.Polyvinyl piping materials adopts in the buried application of non-excavation to some extent at present.But the prior art polyvinyl piping materials also exists poor toughness (particularly notched Izod impact strength is low), elevated temperature strength insufficient rigidity, the not high shortcoming of temperature classification, can't finely satisfy the buried harshness of non-excavation and use.
In the prior art, duct products need spray respective identification at pipeline outer-layer usually owing to need information such as record model, type, material; Yet in pipe production, transportation; Cause the quilt of sign to weaken easily or wear and tear, identify long term exposure in addition at skin, also easy oxidized disappearance; Sign often lacks and can't distinguish after buried pipeline uses a period of time, is safeguarding the relevant information that is difficult to discern this pipeline when changing like this.
Summary of the invention
The present invention is directed to defective of the prior art, provide a kind of and have high toughness and higher-strength, have a manufacturing approach of the buried tubing of stable and clear sign simultaneously.
For realizing above-mentioned purpose, the present invention adopts following technical scheme:
Manufacturing approach with buried tubing of sign of the present invention at first, is prepared the component of following ratio: the high density polyethylene (HDPE) of 600 ~ 800 weight portions, the glass fibre of 5 ~ 15 weight portions; The wollastonite of 1 ~ 2 weight portion, the ethylene-propylene diene copolymer of 1 ~ 6 weight portion, the NBR of 4 ~ 9 weight portions; The ethylene-octene copolymer of 3 ~ 6 weight portions, the calcium carbonate superfine powder of 9 ~ 13 weight portions, the polypropylene grafted maleic anhydride of 10 ~ 30 weight portions; 2,4 of 15 ~ 25 weight portions, the 6-tri-butyl-phenol; The said components mixing after extruding, extruder is processed internal layer; Secondly,, one deck viscose glue is set as binder course, and adds colouring agent in the internal layer periphery through binder course wrapping machine and hauling machine.Then, on binder course, be coated with the sign of mark tubing information through flush coater.The evoh layer skin of transparent resistance oxygen is set in the binder course periphery through outer wrapping machine and hauling machine at last.
Further, colouring agent is lighttight materials such as aluminum paste.
Further, to be mixed with percentage by weight at adhesive-layer be 0.1%～6% to aluminum paste.
The buried tubing that manufacturing approach of the present invention makes with sign; Internal layer is primary raw material with the high density polyethylene (HDPE); The compound that adds inorganic matter is main reinforcing agent; Through reinforcing agent is carried out suitable surface treatment; And utilize rubber-like elastomer and thermoplastic elastomer (TPE) that inorganic matter is suitably wrapped up processing, improve its dispersiveness in macromolecule matrix, and form suitable interface interaction with matrix; Solve at present inorganic modified dose and strengthen not quite even significantly common problem such as reductions of the common intensity increase rate that faces of macromolecule big and other performance such as impact, outward appearance, processing characteristics increase rate, realize inorganic modified dose of significantly other performance of unlikely deterioration enhancing the time to a certain extent.And adopt a small amount of ultra-fine powdery nano material simultaneously, make that poly crystallization realizes the effect of heterogeneous nucleation can improving poly degree of crystallinity greatly.Because the bonding interface degree of nanometer materials and polyethylene polymer is high, can improve the impact strength of composite polyethylene material and the mechanical property of polymer well.And add crosslinking agent and make mentioned component crosslinked compatible more easily, it is oxidized that antioxidant makes that material is difficult for, and stability strengthens greatly.In addition, the tubing marking ink-jetting is outer at internal layer, and through transparent outer tube protection; Solve tubing and be marked at production, use and store in produce problem such as thin out, disappearance, both artistic and practical; And the adjustment of flexible compound pipe marking process is simple; Do not increase equipment and production cost, practical, exploitativeness is high.
