Abstract
The utility model provides a kind of underground communication plastic silicon core tube, including body, the body inner tubal wall are provided with silicon core layer, and the outer tube wall of the body is coated with antioxidant coating, and the body is coated with silastic-layer.Antioxidant coating is coated with by the outer tube wall in high density polyethylene pipe body, prevent oxygen to contact with body, prevent thermal oxidation from decline tube body performance, improve the ageing-resistant performance of body, body is coated with silastic-layer, without unsaturated bond in silicon rubber main chain, in addition Si O Si keys are sufficiently stable to oxygen, ozone and ultraviolet etc., even if for a long time in ultraviolet and wind and rain, the change of its physical and mechanical properties is little, the ageing-resistant performance of body is further improved, prevents high density polyethylene pipe body from ftractureing, substantially prolongs the service life of silicone pipes.
Description
Technical field
Communication line field is the utility model is related to, specially a kind of underground communication plastic silicon core tube.
Background technology
Into the optical-fibre communications epoch, optical cable is typically buried in underground, to be effectively protected optical cable, is generally added outside optical cable
Protection sleeve pipe.During cable run, the tubing used at first is steel pipe, pipe of cement, pvc pipe and double-wall corrugated pipe, is made
With it is middle maximum the problem of be the lubrication problem that how to solve to wear inner-walls of duct in cable, it is general using coating when being constructed with aforementioned tubes
The method of lubricant, i.e., the lubricant of liquid is first coated in pipe material inner wall before cable is worn, but due to the effect of gravity, makes lubrication
Agent can not be uniformly distributed in pipe material inner wall, and the cable that can be also dried when wearing cable by leading portion is taken away, and lubrication problem is direct shadow
Ring the length and speed for wearing cable.
Protection sleeve pipe of the silicone pipes used at present as optical cable, because silicone pipes inwall silicon core layer is permanent solid profit
Lubrication prescription layer, silicone pipes coefficient of friction is smaller, and cable can extract repeatedly in pipe, prevents cable from peeling off, departing from, therefore, silicone pipes
It is widely used in a variety of applications in underground communication field.But existing silicone pipes outer layer is high density polyethylene (HDPE), ageing-resistant performance
And ESCR is poor, the oxygen of silicone pipes, ozone and UV stable are general, for a long time under external environment,
Easily silicone pipes are caused with the damage of degree, greatly shortens the service life of silicone pipes.
Utility model content
The purpose of this utility model is to provide a kind of underground communication plastic silicon core tube, improves ageing-resistant performance and resistance to ring
Border cracking behavior, extend the service life of silicone pipes.
In order to realize above-mentioned purpose of utility model, the technical solution adopted in the utility model is：A kind of underground communication modeling
Expect that silicone pipes, including body, the body inner tubal wall are provided with silicon core layer, the outer tube wall of the body is coated with antioxidant coating,
The body is coated with silastic-layer.
Compared with prior art, technique effect of the present utility model is：In such scheme, by high density polyethylene pipe
The outer tube wall of body is coated with antioxidant coating, prevents oxygen and is contacted with body, prevent thermal oxidation from decline tube body performance, carries
The ageing-resistant performance of high body, body are coated with silastic-layer, without unsaturated bond in silicon rubber main chain, Si-O-Si keys in addition
It is sufficiently stable to oxygen, ozone and ultraviolet etc., thus integrally there is excellent weatherability without any additive, i.e. silicone pipes,
Even if for a long time in ultraviolet and wind and rain, the change of its physical and mechanical properties is little, further improves the ageing-resistant of body
Performance, prevent high density polyethylene pipe body from ftractureing, substantially prolongs the service life of silicone pipes.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The utility model is described in further detail with reference to Fig. 1.
A kind of underground communication plastic silicon core tube, including body 1, the inner tubal wall of body 1 are provided with silicon core layer 2, the pipe
The outer tube wall of body 1 is coated with antioxidant coating 3, and the body 1 is coated with silastic-layer 4.
In such scheme, antioxidant coating 3 is coated with by the outer tube wall in high density polyethylene pipe body 1, prevents oxygen
Contacted with body 1, prevent thermal oxidation from making the hydraulic performance decline of body 1, improve the ageing-resistant performance of body 1, body 1 is coated with
Silastic-layer 4, without unsaturated bond in silicon rubber main chain, Si-O-Si keys are sufficiently stable to oxygen, ozone and ultraviolet etc. in addition, because
Without any additive, i.e. silicone pipes integrally have excellent weatherability, even if for a long time in ultraviolet and wind and rain,
The change of its physical and mechanical properties is little, further improves the ageing-resistant performance of body 1, prevents high density polyethylene pipe body 1 from ftractureing,
It substantially prolongs the service life of silicone pipes.
Preferably, the antioxidant coating 3 is aluminized coating or aluminum oxide coating.
Axially extending identification colour band groove 41 is offered on the outer wall of silastic-layer 4, is set in the identification colour band groove 41
There is identification colour band.Identification colour band groove 41 opens up conveniently on the outer wall of silastic-layer 4, identifies colour band personal identification silicon core easy to operation
Pipe.
