Description
Technical field
The present invention relates to a kind of Optical Fiber composite overhead Ground Wire optical fiber filling paste and preparation method thereof.
Background technology
Optical Fiber composite overhead Ground Wire (OPGW optical cable, below all be called the OPGW optical cable), as its name suggests, the dual-use function that it has ground wire and optical cable gets up fiber optic protection with metal construction, thereby forms best version reliably.Since in the OPGW optical cable optical fiber have anti-electromagnetic interference (EMI), from characteristics such as heavy and lights, it can be installed in the electric power line pole tower top and needn't consider that best frame hangs problems such as position and electromagnetism corrosion.Thereby OPGW has distinguishing features such as higher reliability, superior mechanical property, cost be also lower.This technology is especially suitable and economical when newly laying or changing existing ground wire.
Along with the continuous development of power communication, the OPGW optical cable also increases day by day in the utilization of high-voltage power circuit.Power circuit is all using the OPGW optical cable from 110kV to 500kV and even the 750kV and the power circuit of voltage levels very on a large scale, and the reliability of power communication, the technical merit of communication etc. are greatly improved.Planning according to State Power Corporation and state telecommunication center, the development of power communication from now on will be the center to accelerate the reconstruction of photoelectricity network, attach most importance to the power information resources development and utilization, actively push forward the application of new and high technology in power communication, build up the communication backbone network of modernization " three horizontal four is vertical " based on optical communication; The Eleventh Five-Year Plan period, along with the enforcement of Three Gorges Power " west-to-east power transmission ", 3G network construction operation, the demand of OPGW optical cable will grow with each passing day; Because it is later that China develops the OPGW optical cable, just begin to take shape through in recent years development.
Optical fiber filling paste is the material that is used in the filled fiber cable optical fiber loose tube.It has the protective effect of two aspects to optical cable: the one, prevent that moisture content or airborne moisture from corroding optical fiber; the 2nd, optical cable is played the liner effect; the influence of mechanical forces such as buffered optical fibers is vibrated, impact, bending is one of decisive key element that properties of optical fiber cable can be steady in a long-term.It is mainly by base oil, viscosifying agent, and the antioxidant three parts are formed.
OPGW optical cable any optical cable product different from the past, it merges optical fiber communication on the basis of aerial earth wire, place optical fiber in metal tube, require optical fiber can both keep reliable and stable optical transmission performance under various weather conditions, this has proposed requirements at the higher level just for the OPGW optical fiber filling paste.These main performance index performances are as follows:
1, anti-flammability---the light unit in the OPGW optical cable is formed through laser bonding by sheet metal, in manufacture process, can produce a large amount of heats, cause the filling paste temperature to raise, if fine cream flash-point is low, will produce burning, even do not burn, also can destroy the colloform texture of fine cream, thereby influence the transmission performance of optical fiber; Thus, the flash-point of the fine cream of OPGW should and should have certain anti-flammability greater than 230 ℃.
2, inhale hydrogen---well-known, the natural enemy of optical fiber is a hydrogen, and the hydrogen in the OPGW optical cable can enter the armouring optical cable by two kinds of approach, the one, the metal parts of optical cable inside is owing to corrode and releasing hydrogen gas when operation; The 2nd, by the laser beam welding of sealing stainless-steel tube; Hydrogen that produce in welding process or that emit in operational process has nowhere to run, and they see through factice for filling and arrive optical fiber surface, penetrates into fibre coating then and enters fibre core and finally combine with glass optical fiber; Thereby cause the optical fiber transmission signal decay to increase, reduce transmission performance; This infringement is mainly reflected in three aspects:
(1) molecule absorption---hydrogenation is adsorbed on optical fiber surface, thereby the luminous energy that the hydrogen that is adsorbed has absorbed in the transmission data frequency scope increases signal attenuation.
(2) hydrogen is by being reflected at the inner hydroxyl that generates of glass core---the absorption of vibrations of hydroxyl the luminous energy in the transmission data frequency scope signal attenuation is increased.
(3) thus hydrogen generates fault by being reflected in the glass core---the optical characteristics that these faults have changed glass optical fiber influences the signal transmission.
At above-mentioned these phenomenons, the OPGW optical fiber filling paste must possess " inhaling the hydrogen agent " system with " suction hydrogen " function, and it can effectively absorb or keep here any molecular hydrogen.
3, the optical fiber filling paste that thixotropy---thixotropy is good can make optical fiber reach cable core in sleeve pipe can be in unstress state the most freely all the time in cable, so just reduced the microbending loss and the stress corrosion of optical fiber under stress, moisture content and moisture effect of optical fiber.When this fine cream is subjected to stress (as the carrying of optical cable, lifting etc.), demonstrate the same state of solid optical fiber to be fixed motionless; And when this stress is higher than a critical value (as by bending, make a dash hit etc.), filling paste will flow, and viscosity then descends rapidly, and like this, optical fiber almost can not have bending with regard to dischargeing these suffered stress when being subjected to stress.And, because the thermodynamics phase of this filling paste tendency is solid-state, so filling paste reverts to high viscosity gradually again and optical fiber is fixed after the optical fiber freedom; Improved the transmission quality of optical cable greatly.Thixotropic index value computing formula: the thixotropic index value equals: the ratio of viscosity number when viscosity number during shearing rate D=6 and shearing rate D=200, this ratio is the bigger the better.
4, analyse oil---analysing oil is to examine the oily at a certain temperature quantity of separating from filling paste.Oil is excessive, then in use oil easily separates drippage from cable core if analyse, thereby will cause the ointment hardening that optical fiber is produced stress, influences the transmission quality of optical cable; The oil mass of analysing of filling paste raises with temperature and increases, and it is the smaller the better to analyse oil theoretically, but the too little of regulation will be brought difficulty to manufacturing, also is considerable from cost performance.Analyse the big young pathbreaker of oil mass and directly have influence on optical cable compatibility and optical cable drip characteristic.
The applicant has developed a kind of Optical Fiber composite overhead Ground Wire factice for filling in 2004, and applied for that (application number is called " Optical Fiber composite overhead Ground Wire factice for filling " for " 200410025323.2 ", name to patent of invention, this factice for filling is by with 36# hydrogenation white oil, the PAO-8 synthetic oil, after PriC0-3002 polyol ester and viscosity index improver Lc-212 mix, add adjuvant OB type fluorescer, oil dividing inhibitor BP2400 and G1702, heat up and stir, add organic viscosifying agent gas-phase silica H then
20The multiviscosisty of heating adds antioxidant AT-215 and the inorganic thickening agent SEP1650 multiviscosisty of heating again, shears through homogenizing, is chilled to normal temperature behind the circulation feed back, makes behind the homogenizing degassing filter again.
But continuous development along with power communication, requirement with optical fiber filling paste also improves gradually for the OPGW optical cable, above-mentioned Optical Fiber composite overhead Ground Wire can not finely satisfy the required requirement of power communication with the prescription and the performance index of factice for filling, lower as thixotropy, anti-flammability and suction hydrogen number, it is more high to analyse oil.
