Description
Technical field
The present invention relates to the communications fields, and in particular to a kind of novel termite proof cable.
Background technique
In today of high speed information development, requirement of the communication service to network bandwidth is higher and higher, and fiber optic communication is as speed
It spends most fast, the best communication mode of transmission quality and is widely used.In network construction, with communication globalization development,
The service life of optical cable, transmission speed and other properties are proposed more because of local condition problem etc. all over the world
High requirement.There are ants to suffer from seriously for some areas, and termite corrodes optical cable phenomenon and takes place frequently, and the optical cable that can be greatly reduced uses the longevity
Life；
Existing some termite proof cables are expected as outer shield using nylon material, to prevent ant mouse from biting damage, but still can not
Guarantee safe protection optical cable, or there is damage phenomenon, influences the service life that optical cable uses.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of novel termite proof cables, and termite can be effectively prevent to corrode light
Cable.
In order to solve the above-mentioned technical problems, the present invention provides a kind of novel termite proof cables, which is characterized in that including center
Reinforcer, being twisted on the outer surface of the center reinforcemen has Loose tube and gasket for packing, and optical fiber list is provided in the Loose tube
Member and first blocks water substance, and the fiber unit is fiber optic bundle, and described first substance that blocks water is the fiber paste that blocks water, in twisted pine set
Oversheath is coated on pipe and gasket for packing outer surface, the material of the oversheath is ketone polymer and its compound.
Further, according to parts by weight, the ketone polymer and its compound include following component：Natural rubber
40-50 parts, 30-50 parts of solution polymerization styrene-butadiene rubber, 10-20 parts of neodymium series butadiene rubber, 20-25 parts of polyvinylpyrrolidone,
10-20 parts of flame-retardant additive, 2-8 parts of tackifier, 3-9 parts of silica, 1-3 parts of zinc salt of 2 mercaptobenzimidazole, polyimides
8-15 parts and antibacterial peptide 3-5 parts.
Further, also twisted on the center reinforcemen outer surface to have second to block water substance, described second blocks water substance
For the yarn that blocks water, tear rope is additionally provided in the armor.
Further, inner sheath, the inner sheath surface are also wrapped on twisted Loose tube and gasket for packing outer surface
It is coated with armor, the oversheath is coated on armor, and the armouring layer surface is provided with multiple support rods, the branch
It supports rib to be arranged along armor axial direction, forms filled cavity, institute with armor surface engagement between two neighboring support rod
It states and high temperature resistant heat insulation layer is set in filled cavity.
Further, the armor material is consistent with the material of oversheath.
Further, prevention label is additionally provided on the oversheath outer surface, the prevention label includes clamping portion, institute
It states to be provided on clamping portion and puts box body, described put is provided with box cover on box body, the box cover surface is provided with paper labels
Area is labelled, via hole is offered on the outer wall for putting box body, the box portion outside also note of putting is equipped with plastic envelope, the modeling
Expect covering cladding box cover and via hole setting, is provided with wood chip in the box for holding body, termite medicine is provided on the wood chip.
Further, score meter, the termite medicine include following component by weight：20-50 parts of Biphenthrin, glycine
20-25 parts, 10-15 parts of alanine, 8-15 parts of serine, 15-20 parts of honey, 15-25 parts of fluorescer, the chloro- 2- phenylphenol of 4-
5-9 parts, 10-16 parts of chromic salts, 20-25 parts of sodium molybdate, 18-23 parts of sodium tungstate and 40-60 parts of water.
Further, more conductive filaments are also embedded in the oversheath, the spacing between two adjacent conductive filaments is
0.3-0.8mm, the diameter of the conductive filament are 0.8-1.5mm.
Beneficial effects of the present invention：
Ketone polymer and its compound are a kind of novel environmentally protective polymer, and ketone polymer is mainly by an oxidation
Carbon and olefinic polymerization form, and are the substance that carbon atom is substantially on a main chain, crystallinity with higher and compact knot
Crystal structure is a kind of new green environment protection type high molecular material, and it is steady to soda acid that ketone polymer and its compound main chain contain C-C
Fixed, chemical resistance is top.Termite, which corrodes, decomposes cable surface mainly by by secretion formic acid, ketone polymer and its multiple
Closing the excellent anti acid alkali performance of object can may insure that optical cable prevents formic acid from corroding, and guarantee that ant suffers from the service life that the regional optical cable that takes place frequently uses,
And ketone polymer and its compound hardness with higher itself, excellent shock resistance, crocking resistance etc., to optical cable
Mechanical performance itself also has very big promotion.
Detailed description of the invention
Fig. 1 is overall structure diagram of the invention；
Fig. 2 is the schematic diagram of another embodiment of the present invention；
Fig. 3 is the schematic diagram with prevention label of the invention.
Specific embodiment
The present invention will be further explained below with reference to the attached drawings and specific examples, so that those skilled in the art can be with
It more fully understands the present invention and can be practiced, but illustrated embodiment is not as a limitation of the invention.
Shown in referring to Fig.1, an embodiment of novel termite proof cable of the invention, including center reinforcemen 1, center reinforcemen
Outer surface on be twisted and have Loose tube 2 and gasket for packing 3, fiber unit 4 and first is provided in Loose tube and is blocked water substance 5, optical fiber
