Abstract
The invention relates to an optical fiber ribbon coating paste used in a band shape optical cable. The paste is mainly composed of a base oil, an oil separation inhibitor, a pour-point depressant, an anti-oxidant, a tackifying lubricant, an organic densifier and a thixotropic agent. The invention also provides a preparation method of the paste. The optical fiber ribbon coating paste is mainly characterized by good colloid stability, oxidation stability, hear resistance and weatherability, free oil separation system, low acid value, large penetration degree, strong clunging, good permeability and low viscosity. The paste can help the optical fiber ribbon of the band shape optical cable always stay at a most stress-free state in the loose cannula and the cable core of the cable.
Description
Technical field
The present invention relates to a kind of fibre ribbon coating paste and preparation method thereof, relate in particular to a kind of optical fiber ribbon coating paste used in band shape optical cable and preparation method thereof.
Background technology
Along with the fast development of LAN (Local Area Network) and Optical Access Network, the epoch of high-density optical-fiber network arrive, and the optical cable of large core number---optical fiber ribbon cable progressively adopts in the construction of communication network.The construction of fiber optic network is gradually by national backbone network turn-around zone net and metropolitan area Access Network at present, and the high speed development of Metropolitan Area Network (MAN) and Access Network will increase the demand to optical fiber, and optical fiber ribbon cable is because its optical fiber integrated level is high and the laying expense is hanged down and will be used widely; Since the optical fiber ribbon cable structure singularity---loose casing diameter is more many greatly (about ordinary optical cable ferrule Φ 1.8mm than the diameter of ordinary optical cable, about optical fiber ribbon cable light sleeve pipe Φ 12mm), in order to ensure optical fiber ribbon cable drip not under 80 ℃ of high temperature, the cone penetration of the fine cream of the optical fiber ribbon cable generally cone penetration than the fine cream of ordinary optical cable is little, fine cream cone penetration is little just to mean that fine cream is thicker, and the optical fiber in the optical fiber ribbon cable normally is present in the optical fiber loose tube with flat assembly carrier state, because fine cream is thicker, the fibre ribbon surface will produce and fill discontented phenomenon in filling process, will cause the optical fiber surface discontinuity like this, thereby generation stress causes the Optical Fiber Transmission performance degradation.The method that addresses this is that can add fine cream coating unit one in the front of fibre ribbon pine cover, this fine cream must possess the performance of little viscosity and large cone penetration, and the flowability of fine cream must be good, strong adhesion, good penetrability and technical indicator will meet the requirement of common fine cream, can not analyse oil.The cone penetration index should be greater than 5001/10mm in the time of 25 ℃; Viscosity index in the time of 25 ℃ less than 3500mpa.s.
At present, optical fiber ribbon cable producer increases gradually for the demand of fibre ribbon coating paste on the home market, viscosity is little because this coating paste has, cone penetration large (fine cream is rarer), strong adhesion, the characteristics such as good penetrability, it can make coating paste infiltrate equably and be coated in the fibre ribbon surface, guarantee that ribbon fiber reaches cable core and can be in all the time the most freely unstress state in cable in loose sleeve pipe, reduce microbending loss and the stress corrosion of fibre ribbon under stress, moisture content and moisture effect of fibre ribbon.
But there is no in the market the real fibre ribbon coating paste that can reach above-mentioned requirements.
Summary of the invention
Purpose of the present invention provides a kind of optical fiber ribbon coating paste used in band shape optical cable for the problems referred to above exactly, and this fibre ribbon coating 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 fibre ribbon coating paste.
The present invention in order to reach the goal used technical scheme is:
A kind of optical fiber ribbon coating paste used in band shape optical cable comprises following feed composition and weight percent content thereof:

Above-mentioned optical fiber ribbon coating paste used in band shape optical cable, 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 the high molecular polymer thermoplastic synthetic rubber, and described tackify lubricant is selected from the high molecular polymer synthetic rubber.
Above-mentioned raw materials is the commercially available prod.
The present invention also provides a kind of preparation method of above-mentioned optical fiber ribbon coating paste used in band shape optical cable, may further comprise the steps:
First 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, add the tackify lubricant, after the insulated and stirred 1～3 hour, add antioxidant and stir again 0.5-1 hour, and then cooling down to 50 ℃～80 ℃, add thixotropic agent, fully feed back stirred after 1～3 hour, grind through homogeneous, vacuum outgas obtains final products.
Among the preparation method of above-mentioned optical fiber ribbon coating paste used in band shape optical cable, described final products are water white transparency shape colloid.
Optical fiber ribbon coating paste used in band shape optical cable of the present invention, its principal character is not contain the fine cream product of making as main thickening agent take inorganics gas-phase silica (silicon dioxide) in traditional fine paste formulation, it take the organic polymer synthetic polymer as main thickening agent in addition the tackify lubricant make, its key property is to have good colloid stability and oxidation stability, thermotolerance, weatherability, system is little regardless of oil, acid number; Large cone penetration, strong adhesion, good penetrability, low viscosity, it can make fibre ribbon reach cable core in loose sleeve pipe can be in the most freely unstress state all the time in cable.
Optical fiber ribbon coating paste used in band shape optical cable product of the present invention need not heat when applying, apply behind the ribbon fiber and can play the effects such as good protection against the tide, waterproof, shockproof, buffering, anti-high and low-temp to optical fiber ribbon cable, to oversheath in the optical fiber ribbon cable and optical fiber with good compatibility.This product processing technique is simple, and production environment cleans, pollution-free, water resisting property is strong, and high temperature performance is good, is novel Green Product.
