Background technology
China's plastic conduit have developed rapidly, and quality is improving constantly.At present, preliminarily formed with polyvinyl chloride pipe, poly- second
Plastic tube industry based on alkene (PE) pipe and polypropylene (PP-R) pipe.Wherein polyethylene (PE) pipe due to its own it is unique the advantages of
It is widely used in building water supply, construction drainage, buried drain pipe, building and heating, gas transmission and distribution, appendix, electrician and electricity
Interrogate protection sleeve pipe, industrial pipe, agricultural pipe etc..It is mainly used in urban water supply, city gas supply and field irrigation,
Gas supply field, if Patent Office of the People's Republic of China's Authorization Notice No. is CN205261233.U entitled " a kind of freedom from repairs gas pipeline ",
It solves this difficult problem of pipeline maintenance well, but the fire protecting performance of pipeline could not be improved well, and and for example China is special
Sharp office's Authorization Notice No. is CN20422696.U entitled " heat insulation structure of polyvinyl fuel gas pipeline ", and it is well to pipe
Road carries out insulation and fire protecting performance that is heat-insulated, but also not paying attention to pipeline well, therefore, it is proposed that a kind of good airproof performance has
The PE gas pipelines of fire-proof function.
The content of the invention
It is an object of the invention to provide the PE gas pipelines that a kind of good airproof performance has fire-proof function, to solve the above-mentioned back of the body
The problem of fire-proof function difference proposed in scape technology.
To achieve the above object, the present invention provides following technical scheme：The PE that a kind of good airproof performance has fire-proof function fires
Feed channel, including PE pipelines, the outer wall of the PE pipelines are socketed with sealant, and the outer wall of the sealant is socketed with fireprotection layer,
The inner cavity top of the fireprotection layer is provided with silicon oxide layer, and the bottom of the silicon oxide layer is provided with flame-retardant layer, the fireprotection layer
Outer wall be socketed with thermal insulation layer, the outer wall socket matcoveredn of the thermal insulation layer, the inner cavity top of the protective layer is provided with resistance to
Layer is ground, the bottom of the wearing layer is provided with corrosion-resistant coating.
Preferably, the sealant is accordion.
Preferably, the flame-retardant layer is fire resistance fibre film.
Preferably, the wearing layer is entwined for fiber woven belt.
Preferably, the corrosion-resistant coating is polyimide coating.
Compared with prior art, the beneficial effects of the invention are as follows：Sealant is designed as accordion, is to improve sealing
The ductility of layer, will not be broken when expanding with heat and contract with cold, so improve the sealing property and service life of sealant,
In sealant fireprotection layer is externally provided with to can be very good to obstruct the intensity of a fire and prevent fire spreading to inside pipeline, and protective layer then in order to
The service life of pipeline is improved, compared with traditional PE pipelines, the present invention has better seal and fire line.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention；
Fig. 2 is fireprotection layer structural representation of the present invention；
Fig. 3 is protective layer structure schematic diagram of the present invention.
In figure：It is 1PE pipelines, 2 sealants, 3 fireprotection layers, 31 silicon oxide layers, 32 flame-retardant layers, 4 thermal insulation layers, 5 protective layers, 51 resistance to
Grind layer, 52 corrosion-resistant coatings.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other under the premise of creative work is not made
Embodiment, belong to the scope of protection of the invention.
Fig. 1-3 are referred to, the present invention provides a kind of technical scheme：A kind of good airproof performance has the PE Gas Pipes of fire-proof function
Road, including PE pipelines 1, the outer wall of the PE pipelines 1 are socketed with sealant 2, and the outer wall of the sealant 2 is socketed with fireprotection layer 3,
The inner cavity top of the fireprotection layer 3 is provided with silicon oxide layer 31, and the bottom of the silicon oxide layer 31 is provided with flame-retardant layer 32, described
