Description

A kind of cable pipeline
Technical field
The present invention relates to a kind of pipelines, and in particular to a kind of cable pipeline.
Background technology
The communications cable is in construction, it usually needs in pipeline, to realize the physical protections requirement such as waterproof, insulation. Existing cable pipeline generally comprises the insulating layer of rubber, the shielded layer being wrapped in outside insulating layer and more hard and watertightness High water barrier.The insulating layer of rubber has the advantages that insulation performance is good, cheap, quality is slim and graceful, but its thermal expansion contracting system Number is higher, in outside air temperature change dramatically, easily occurs significantly to expand, may cause to have rigid shielded layer, every Water layer ruptures, and What is more causes pipeline internal pressure excessively high and damage cable.
The content of the invention
In view of this, the present invention provides a kind of cable pipeline that can balance internal pressure.
The purpose of the present invention is realized by following technology：A kind of cable pipeline including insulating layer, is wrapped in outside insulating layer Shielded layer, the water barrier being wrapped in outside shielded layer are additionally provided with a buffer layer, the buffer layer between the insulating layer and shielded layer Inside it is provided with several cavitys.
The shielded layer of the present invention, water barrier, insulating layer, can be selected commercially available organic bond bonding between buffer layer and Into.The present invention especially increases by a buffer layer between insulating layer and rigid shielded layer, and buffer layer preferably has certain elastic shape The material for becoming performance is realized, such as engineering plastics；Cavity is equipped in buffer layer, when insulating layer is because temperature change expands or receives During contracting, cavity can be to retain certain deformation space in pipeline, avoid internal pipe pressure excessive and cause shielded layer, water proof Layer deformation is burst apart, and also can effectively prevent the excessively high damage cable of internal pressure.
Further, the buffer layer is made of first buffer layer and the second buffer layer being wrapped in outside first buffer layer； The outer surface of the first buffer layer has indent, circular cambered surface, and multiple concentric annular recess are provided in cambered surface；It is described The position that the inner surface of second buffer layer corresponds to cambered surface is equipped with ventilating zone, and ventilating zone is provided with several ventilation through holes；The cambered surface and Ventilating zone, which encloses, forms the cavity.
The buffer layer of the present invention is made of first buffer layer and the second buffer layer being wrapped in outside first buffer layer, and first is slow Rushing the cambered surface of layer can make cavity become the solid surface of top inwardly, to tackle the pressure essentially from insides of pipes, make sky Chamber drops in pipeline have the ability for still having and recovering shape, avoid being crushed.And through hole of ventilating is subject to greatly in cavity In the case of pressure, pipeline breaking is avoided by discharging the air of cavity.A small amount of air can be discharged into shielded layer and buffer layer Gap.
Further, the shielded layer is metal layer；The inner surface of the shielded layer is provided with groove vertically.
Since pipeline is generally longer, the temperature of each area is inconsistent, therefore the present invention is provided with edge in shielded layer inner surface Axial groove connects each area of full pipeline；When temperatures at localized regions is excessively high, cavity is overly compressed, a small amount of air Entered groove by through hole of ventilating, can the axially displaced region relatively low to pressure, to avoid the rupture of shielded layer.
Further, the outer surface of the first buffer layer is provided with the blind hole of cylindricality；The interior table of the second buffer layer Face is extended with stud bumps corresponding with blind hole position, and stud bumps are inserted into the blind hole.
Since first buffer layer, second buffer layer are relatively independent, when cavity internal pressure is excessive, it is possible to cause the first buffering Layer, the separation of second buffer layer, slip.To avoid the appearance of such case, the present invention by the cooperation of stud bumps and blind hole, Fixed first buffer layer, second buffer layer.
Preferably, the gap filling between the first buffer layer and second buffer layer has white glue with vinyl.
First buffer layer and second buffer layer pass through Virgin's milk glue bond.Any one commercially available white glue with vinyl can be selected to realize.
Preferably, the blind hole is distributed around the cambered surface.
First buffer layer and second buffer layer bond strength around cavity is minimum, therefore the present invention is circular described by blind hole Cambered surface is set, to ensure the stability of cavity shape.
Preferably, the insulating layer is rubber layer；The buffer layer is Polycarbonate Layer；The water barrier is PVC（Polychlorostyrene Ethylene）Layer.
After injection molding tubulose can be used in insulating layer, buffer layer, water barrier, successively it is set with.
Preferably, the water barrier is outer covered with wear-resistant coating；Its raw material of the wear-resistant coating includes by weight
5-10 parts of trimethylolpropane trimethacrylate；
1-5 parts of acrylic acid oligomer；
10-15 parts of methanol；
0.5-1 parts of butyl acetate；
1-5 parts of cyclohexanone；
2-8 parts of isopropanol；
0.5-3 parts of photoinitiator；
1-5 parts of SiO 2 powder；
0.01-0.09 parts of nano aluminium oxide；
0.01-1 parts of neopelex.
Preferably, the photoinitiator is alpha-alcohol ketone；The processing method of the wear-resistant coating is to mix each raw material It is even, at 50-75 DEG C with 10 times of normal atmospheres pressure heat preservation 1 it is small when, be sprayed on water proof layer surface, then with 100- 430mW/cm2 Ultraviolet light 60-120s make paint solidification；Coating thickness is 0.05-0.2mm.
The water barrier of PVC has good weatherability, leakproofness, but its hardness is relatively low, easily wears, and causes under intensity Drop.Therefore the present invention is special for a wear-resistant coating is covered outside water barrier, to improve the wearability of water proof layer surface.Trihydroxy methyl third The realization of any one prior art can be selected in alkane triacrylate, acrylic acid oligomer, can be as the monomer of coating；Especially , acrylic acid oligomer can preferred saturation functional group acrylate, degree of functionality 0-2.SiO 2 powder is preferably grain Commercial product of the footpath between 40-500 μm.Methanol, butyl acetate, cyclohexanone, isopropanol can be selected the prior art and realize.This Invention is especially added with neopelex, as the surfactant of ionic, can effectively reduce uncured liquid The surface of state coating-air interface can, subtle SiO 2 powder is made to be gathered in the surface of coating, after curing of coatings Form the protective shell of layer of silicon dioxide composition.Such as without neopelex, SiO 2 powder will be full of in coating it In, not only protective shell cannot be formed in coating surface, the adhesive force of coating but will be reduced, coating is caused easily to come off.Nano oxygen The hardening time of coating can effectively be reduced by changing the use of aluminium, to improve the speed of production of product.
