Abstract
The invention discloses an optical cable protective casing pipe. The protective casing pipe comprises a high-density polyethylene (HDPE) resin layer, a silicone resin layer and a mark color tape, wherein the HDPE resin layer is arranged on the outer layer of the silicone resin layer, and the mark color tape is arranged on the outer layer of the HDPE resin layer. The invention also discloses a production method of the optical cable protective casing pipe. Low-density polyethylene (LDPE) resin is replaced with HDPE resin, so that the toughness of the pipe is enhanced, and the pipe can be buried and laid directly; no casing is required; the material cost is saved; the silicone resin layer is introduced; the pipe has good lubrication effects; the length of the cable subjected to one-time air blowing by compressed air can exceed 2000m; labor power, material resources and engineering costs are saved greatly; the casing pipe has great economic value and can be applied to industrial production widely; and the mark color tape not only is attractive and elegant in appearance, but also plays recognition roles during a midway continuing process of cables, and the data transmission disorders caused by optical cable misconnection are avoided.
Description
Technical field
The invention belongs to the optical cable protecting casing field.
Background technology
Digital communication is indispensable in the social development in modern times, and the digital communication industry of China is in the develop rapidly stage.At present, data network is all laid in all parts of the country in full preparation, and optical cable just is widely adopted as the carrier of data transmission.Optical cable mainly lay form for bury with built on stilts, and along with the transformation of city gauze, major part goes underground.Suffer the corrosion on the insect bite or the face of land for fear of being embedded in underground optical fiber cable, the sheath tubing of optical fiber and optical cable arises at the historic moment.Early stage these sheath tubing mostly be concrete for making, however this tubing have heaviness, inflexibility, friction factor greatly, shortcomings such as sealing is poor, connection is difficult, construction and transportation cost height.
In order to overcome the many disadvantages of concrete plug, domestic many research institutes and producer's joint research and development low density polyethylene (LDPE) light wall pipe.This product is primary raw material with LDPE, through the single screw extrusion machine extrusion molding, has light weight, bending strength is big, friction factor is little, good seal performance, characteristics such as corrosion-resistant; Some defectives of cement pipe have been overcome; The damage of both having avoided optical cable in wearing the process of leading, to bring because of friction can make optical cable crooked with bending pipes again, thereby adapts to the variation of ground drop or camber; Simultaneously, still be a kind of environmentally friendly machine.
Yet, though this tubing has overcome the part defective of cement pipe, but still exist many deficiencies, like poor toughness; Can not direct-burried, need overcoat PVC corrugated tube or other pliable and tough tubing, material cost is high; The wearing of optical cable led and can only be leaned on the completion that is pulled of craft or machinery, and a threading causes fiber cable joint many apart from weak point (only about 200m); People's well or hand well are provided with many, have both influenced data transmission quality, have increased the cable laying operation cost of optical cable again.
Summary of the invention
The present invention has overcome the deficiency of prior art, and a kind of optical cable protecting casing and preparation method thereof is provided.
For solving above-mentioned technical matters, a plurality of embodiment of the present invention adopt following technical scheme:
A kind of optical cable protecting casing, said optical cable protecting casing comprise polyvinyl resin (HDPE) layer, silicone resin layer and tracer stripe, and said polyvinyl resin layer is arranged on the skin of said silicone resin layer, and said tracer stripe is arranged on the skin of said polyvinyl resin layer.
A kind of preparation method of said optical cable protecting casing forms pipe with said polyvinyl resin layer, said silicone resin layer, said tracer stripe coextru-lamination; Again said pipe is carried out sizing; Pipe behind the sizing is shaped into tubing through water quench; Said tubing to draw faster than the haulage speed of said co-extrusion speed slightly, is made optical cable protecting casing.
Compared with prior art, the beneficial effect of a plurality of embodiment of the present invention is: on the basis of common plastics cable jacket, introduce the HDPE resin and substitute the LDPE resin, increase the toughness of tubing, but the tubing direct-burried is laid and need not overcoat, practiced thrift material cost; Introduce silicone resin and make tubing obtain good lubricant effect, realizing that pressurized air is disposable blows more than the cable 2000m, has saved human and material resources and engineering cost greatly, has very high economic worth, can widespread use in commercial production; Sign chromatape is not only elegant in appearance, and can also play recognition reaction in the handshaking procedure midway at optical cable, avoids the optical cable misconnection and the data transmission disorder that causes.

Fig. 1 is the preparation flow figure of optical cable protecting casing.
Embodiment
Below in conjunction with embodiment the present invention is further specified, but embodiment of the present invention is not limited thereto.
Embodiment 1
A kind of optical cable protecting casing, said optical cable protecting casing comprise polyvinyl resin (HDPE) layer, silicone resin layer and tracer stripe, and said polyvinyl resin layer is arranged on the skin of said silicone resin layer, and said tracer stripe is arranged on the skin of said polyvinyl resin layer.
As shown in Figure 1, a kind of preparation method of said optical cable protecting casing forms pipe with said polyvinyl resin layer, said silicone resin layer, said tracer stripe coextru-lamination; Again said pipe is carried out sizing; Pipe behind the sizing is shaped into tubing through water quench; Said tubing to draw faster than the haulage speed of said co-extrusion speed slightly, is made optical cable protecting casing.
Although invention has been described with reference to explanatory embodiment of the present invention here; But not in order to restriction the present invention; Should be appreciated that; Those skilled in the art can design a lot of other modification and embodiments, and these are revised and embodiment will drop within disclosed principle scope of the application and the spirit.More particularly, in the scope of, accompanying drawing open and claim, can carry out multiple modification and improvement to the building block and/or the layout of subject combination layout in the application.Except modification that building block and/or layout are carried out with improve, to those skilled in the art, purposes of the present invention also will be tangible.
