Description
Technical field
The present invention relates to a kind of optical cable with optical fiber filling paste and preparation method thereof, relate in particular to a kind of optical fiber ribbon cable thixotropy optical fiber filling paste and preparation method thereof.
Background technology
Along with worldwide telecommunication network towards digitizing, broadband, the intelligent direction development, the high speed development of Metropolitan Area Network (MAN) and Access Network will increase the demand to optical fiber, optical fiber ribbon cable is owing to its optical fiber integrated level height and the laying expense is low is used widely, the construction of fiber optic network is gradually by national backbone network turn-around zone net and metropolitan area Access Network at present, in optical fiber Metropolitan Area Network (MAN) and Access Network, because the node that connects is more, often need to lay the optical cable of big core number---optical fiber ribbon cable, adopt optical fiber ribbon cable that many advantages are arranged: its optical fiber integrated level height of optical fiber ribbon cable, be that identical optical fiber can be done the structure of optical cable less, it is less to take route resource; Reduce optical cable welding expense, improve installation effectiveness; Reduce the optical cable cost, because the optical fiber ribbon cable fibre ribbon replaces loose fibre optical cable optical fiber, fibre ribbon has more strong mechanical property than astigmatic fibre simultaneously.
Continuous increase along with the optical fiber ribbon cable demand, optical fiber ribbon cable increases synchronously with the demand of optical fiber filling paste is inevitable, at present, optical fiber ribbon cable on the market uses optical fiber filling paste under the situation of optical cable pine casing diameter greater than 10mm, be difficult to guarantee optical cable the passing through smoothly of drip phenomenon under 80 ℃ of high temperature, the lotion skeleton a little less than, thixotropic index is low, and colloid stability and oxidation stability are not good; The existing fiber filling paste can't guarantee that ribbon fiber reaches cable core and can be in unstress state the most freely all the time in cable in loose sleeve pipe.So just increase the microbending loss and the stress corrosion of fibre ribbon under stress, moisture content and moisture effect of fibre ribbon, greatly reduced the transmission quality of optical fiber ribbon cable.
Summary of the invention
Purpose of the present invention, provide a kind of optical fiber ribbon cable thixotropy optical fiber filling paste at the problems referred to above exactly, this optical fiber filling paste can thoroughly solve use and the protection question of optical fiber ribbon cable under various natural environment and climate conditions, to guarantee the transmission performance of optical fiber ribbon cable.
Another object of the present invention is to provide a kind of preparation method of above-mentioned thixotropy optical fiber filling paste.
The used in order to reach the goal technical scheme of the present invention is:
A kind of optical fiber ribbon cable thixotropy optical fiber filling paste, this optical fiber filling paste comprises following feed composition and weight percent content thereof:
Base oil 70～85%;
Oil dividing inhibitor 5～15%;
Antioxidant 0.3～1%;
Organic viscosifying agent 5～15%;
Inorganic thickening agent 0.3～5%;
Thixotropic agent 1～8%;
Pour-point depressant 0.1～3%.
Above-mentioned optical fiber ribbon cable thixotropy optical fiber filling paste, wherein, described base oil is selected from least a in 3 class hydrogenation white oils and the synthetic oil, described oil dividing inhibitor is selected from polyisobutylene or polybutylene, described antioxidant is high-temp liquid antioxidant, described organic viscosifying agent is selected from high molecular polymer thermoplasticity synthetic rubber, and described inorganic thickening agent is selected from aerosil, and this aerosil is a surface coverage type hydrophobicity aerosil.
Above-mentioned raw materials is the commercially available prod.
The present invention also provides the preparation method of a kind of above-mentioned optical fiber ribbon cable with the thixotropy optical fiber filling paste, may further comprise the steps:
Earlier pour-point depressant is added in the base oil, after the full and uniform stirring, add oil dividing inhibitor, heat and stirred 1～3 hour, when treating that temperature rises to 100 ℃, add organic viscosifying agent, continue to heat and stirred 2～5 hours, treat that temperature rises to 160 ℃, stop to heat, insulated and stirred added antioxidant and stirred 0.5～1 hour again after 1～3 hour, and then cooling is cooled to 50 ℃～80 ℃, add thixotropic agent and inorganic thickening agent, fully feed back stirred after 1～3 hour, ground through homogeneous, vacuum outgas obtains final products.
Optical fiber ribbon cable of the present invention thixotropy optical fiber filling paste, its key property are that the lotion skeleton is strong, the thixotropic index height, and the high temperature drip is good, and has good colloid stability and oxidation stability, thermotolerance, weatherability, system are regardless of oil, acid number is little; It can make ribbon fiber reach cable core in loose sleeve pipe can be in unstress state the most freely all the time in cable.The microbending loss and the stress corrosion of fibre ribbon under stress, moisture content and moisture effect of fibre ribbon have so just been reduced.When this optical fiber filling paste 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, fibre ribbon 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 semisolid gradually again and fibre ribbon is fixed after the fibre ribbon freedom; Improved the transmission quality of optical fiber ribbon cable greatly.And the ordinary optic fibre filling paste is when being subjected to these stress, and fibre ribbon will be subjected to stress simultaneously, makes fibre ribbon be in the local stress state in long time, produces big curved and microbending loss, produces stress corrosion under the moisture content effect.
Optical fiber ribbon cable of the present invention need not heat when filling with thixotropy optical fiber filling paste product, fill behind the optical fiber ribbon cable and can play effects such as good protection against the tide, waterproof, shockproof, buffering, anti-high and low-temp, oversheath in fibre ribbon, the optical cable is had good compatibility optical fiber ribbon cable.This product processing technique is simple, production environment cleaning, pollution-free, water resisting property is strong, high temperature performance is good, is novel Green Product.
