The accompanying drawing to be used needed for having technology description is briefly described, it should be apparent that, and the accompanying drawing in describing is of the invention one
A little embodiments, to those skilled in the art, on the premise of creative work is not paid, can also be according to these
Accompanying drawing obtains other accompanying drawings.
Fig. 1 is the plastic-aluminum combined flame-retardant shielding electrical casing pipe example structure schematic cross-sections of PVC.
With reference to embodiment, and referring to the drawings, realization, functional characteristics and advantage to the object of the invention are made furtherly
It is bright.
Specific embodiment
In order that invention purpose, technical scheme and advantage it is clearer, below in conjunction with the embodiment of the present invention in it is attached
Figure, is clearly and completely described, it is clear that described embodiment is invention one to the technical scheme in the embodiment of the present invention
Section Example, and still whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art are not doing
The every other embodiment obtained on the premise of going out creative work, belongs to the scope of protection of the invention.
As shown in figure 1, the present invention provides a kind of plastic-aluminum combined flame-retardant shielding electrical casing pipe embodiments of PVC.
The plastic-aluminum combined flame-retardant shielding electrical casing pipes of the PVC include setting PVC internal layers 1 and PVC outer layers 2, in the PVC internal layers 1
Aluminium foil layer 3 is provided with and PVC outer layers 2 between.The pipe thickness of the cable conduct is 1.8mm.
Specifically, the PVC internal layers 1 are after the outer cladding aluminium foil layer 3 of PVC internal layers 1 then right by after extrusion forming
The infrared heating of aluminium foil layer 3 is coated, can be in close contact with PVC internal layers 1, then the PVC internal layers 1 for coating aluminium foil layer 3 are passed through
Secondary extrusion, in the outer formation PVC outer layers 2 of the PVC internal layers 1 of cladding aluminium foil layer 3, then to coating the infrared heating of aluminium foil layer 3, makes it
Close contact can be formed with PVC internal layers 1 and PVC outer layers 2.PVC outer layers and PVC internal layers are used or addition has flame-retarding characteristic
Material.
Due to being provided with aluminium foil layer between the PVC internal layers and PVC outer layers, on the one hand the aluminium foil layer can be played to outside
The shielding action of the interference of electric signal, improves the stability and reliability of electric wire transmitting telecommunication number in pipe sleeve, while the aluminium
Layers of foil is electrically conductive, and metal intercommunication can be realized after cable conduct can be contacted by special accessory, can possess ground wire work(
Can, there is wire short-circuiting or artificially touch electric wire, electric current just can decompose underground by aluminium foil, would not be to human body structure
Into electric shock.Using the aluminium foil coated using infrared heating, it is ensured that the flexibility of pipe bending, appearance point is not easy during bending
Layer phenomenon.
Combined closely to preferably be formed PVC internal layers 1 and PVC outer layers 2, netted friendship is provided with the aluminium foil layer 3
The first through hole being relatively large in diameter and less second through hole of diameter of distribution are pitched, wherein PVC internal layer surfaces are filled in the second through hole,
PVC superficies are filled in first through hole.Surface melting is set to fill the through hole of aluminium foil second by the way of infrared heating, so that with
Formed to be in close contact between PVC internal layers and closed, during to being molded PVC internal layers again outside the PVC internal layers for coating aluminium foil, molten condition
PVC cladding materials fill first through hole, the phase is also formed with PVC outer layers and are in close contact, it is ensured that the flexibility of pipe bending, curved
It is not easy lamination occur when bent.The through hole of diameter second of the first through hole, because in PVC after formable layer
There is certain solidification on its surface, even if cannot also make the PVC internal layer surfaces can be with filling aluminum in PVC internal layer surfaces cladding aluminium foil immediately
The second through hole being distributed on paper tinsel, thus by aiding in heating, such as infrared heating enables PVC internal layer surfaces to fill first through hole, together
When do not make yet because over-heating make PVC internal layers melt deformation.Second through hole is to be molded PVC again after PVC internal layers cladding aluminium foil
Be filled during outer layer, during the outer formable layers of the PVC, PVC material be in approximate fluid can shape, led to so as to fill first by extruding
Hole, if first through hole is identical with the second through-hole diameter, fills, it is impossible to formed tightly with PVC outer layers when easily being heated by PVC internal layers
Close combination.
This sleeve pipe uses fire proofing, it is ensured that electrical casing pipe in itself will not be combustion-supporting；
Signal shielding, pipeline intermediate layer is aluminium foil, can play signal shielding effect, prevents signal between line and line from doing
Disturb, especially for the more families of intelligent equipment, many circuits are probably that a pipe is multi-thread or multitube is multi-thread, anti-stop signal
Interfere even more abnormal important；
Wire is conductive, and cable conduct not only can be altered Lian Houneng by this kind of electrical casing pipe with threading wire by special accessory
Metal intercommunication is enough realized, can possess ground wire function, if there is wire short-circuiting or artificially touch electric wire, electric current can just lead to
Cross aluminium foil and decompose underground, electric shock would not be constituted to human body, can effectively ensure owner's personal safety, particularly
Old man and the personal safety of child.
It is easy to bending, the aluminium foil in the middle of pipeline is coated using infrared heating, increased the flexibility of pipe bending, bends
Performance is more preferably, more superior.It is demonstrated experimentally that plastic-aluminum electrical casing pipe, 90 degree, 180 degree, under 360 degree of bending conditions, it is not stratified, no
Fracture；
Resistance to compression anti-impact, it is demonstrated experimentally that the electrical casing pipe using plastic-aluminum technique productions out, its resistance to compression impact capacity is more
By force, due to middle layer of metal aluminium foil more, can effectively prevent the cement mortar from entering pipeline lining, block pipeline, make pipeline
Threading is more unimpeded.
The present invention also provides a kind of plastic-aluminum combined flame-retardant shielding electrical casing pipe manufacturing equipment embodiments of PVC.
The plastic-aluminum combined flame-retardant shielding electrical casing pipe manufacturing equipments of the PVC include：First Screw Extrusion module, the second screw rod are squeezed
Go out module, aluminium foil cladding welding module, heated-air drying module, sizing water tank, cooling water tank, traction module and control each module association
Adjust working control module.Wherein described first Screw Extrusion module is molded for PVC internal layers 1, the second Screw Extrusion module
PVC outer layers 2 for having coated the PVC internal layers 1 of aluminium foil layer 3, i.e., be molded for PVC outer layers 2, and the aluminium foil coats welding module
For aluminium foil layer 3 to be coated on into PVC internal layers 1, the heated-air drying module is used to reduce shrink material.The sizing water tank is used
State sizing when being molded to sleeve pipe, the cooling and shaping when cooling water tank to sleeve pipe to for being molded, the traction module
For the sleeve pipe traction to being molded.
Specifically, the first Screw Extrusion module, the second Screw Extrusion module, aluminium foil cladding welding module, hot blast
Irradiation modules, sizing water tank, cooling water tank, traction module and each module of control etc. can be realized using prior art, also wrapped
Include necessary tube extrusion die and aluminium foil coating mould.In the present embodiment, the first Screw Extrusion module, the second screw rod
