Description
Technical field
The present invention relates to a kind of optical fiber filling paste and preparation method thereof, particularly relate to a kind of optical fiber for optical cable loose tube
Filling paste and preparation method thereof.
Background technology
The after-contraction phenomenon of optical cable loose tube is inevitable problem in ferrule production process.For poly-to benzene two
For formic acid butanediol ester (PBT, hereinafter referred to as PBT) material, crystallization rate is very fast, and material is once less than polymeric
Fusing point begins to crystallization.This causes crystallizing during casing-contact traction wheel being just nearly completed, and for Loose tube, length can contract
Short, non-refractory, chance high temperature is yielding, and notch impact strength is low, and molding shrinkage is big.This contraction is used for producing and controlling optical fiber
Remaining long also being controlled by the tank of each section of different temperatures, this will give production technology, operation, technical parameter etc. bring uncertain because of
Element, thus affect the transmission performance of optical cable.
For polypropylene (being called for short PP) material, its crystallization process is the most, and molecular structure is simple, symmetrical, belongs to
In non-polar conformations, being difficult to the moisture absorption, inactive group, chemical stability is good.And have the most comprehensive through modified polypropylene
Closing mechanical performance and environmental performance, especially for high fiber count cable, caliber is easier to do greatly；PP material bending, after-contraction,
The aspect such as heat ageing, hydrolysis all has obviously advantage, and these performance indications will directly influence the use longevity of optical cable
Life and transmission performance, these advantages are difficult to be designed by structure or other elements make up.
PP material is crystal type high polymer, is material the lightest in common plastics, and density is only 0.91g/cm3 and (compares water
Little).For end user, use the optical cable cheaper of PP (PP price is cheap more a lot of than PBT) sleeve pipe, comprehensive
PBT sleeve pipe can be better than, so PP sleeve pipe cable manufactures is used widely at European & American Market.
At present, PP sleeve pipe cable manufactures production quantity is few, and its main cause is the optical fiber of supply on current cable market
Filling paste and the compatibility extreme difference of PP material, at high temperature (80 DEG C, 672h) PP material is almost melted, even if at room temperature by fine cream
The compatibility also extreme difference under environment.
Summary of the invention
The purpose of the present invention, it is simply that provide a kind of optical fiber filling paste for optical cable loose tube for the problems referred to above, should
Optical fiber filling paste can meet the use under the conditions of various natural environment and climates of the sleeve optic cable Loose tube and protection question, it is ensured that optical cable
Transmission performance.
Further object is that the preparation method that a kind of optical fiber filling paste for optical cable loose tube is provided.
Present invention technical scheme used in order to reach the goal is: a kind of optical fiber filling paste for optical cable loose tube, this optical fiber
Filling paste includes following raw material components and weight percent content thereof:
Base oil: 70-85%；

Preferably scheme is that described antioxidant is high-temp liquid antioxidant.
Preferably scheme is that described thickening agent is methyl hydroxyethylcellulose, ethylhydroxyethylcellulose, methylhydroxypropyl
At least one in cellulose, hydroxyethyl cellulose.
Present invention also offers the preparation method of a kind of above-mentioned optical fiber filling paste for polypropylene sleeve optical cable, including with
Lower step: first join in base oil by viscosifier, after full and uniform stirring, adds viscosity index improver, stirring 1.5 of heating
～2.5 hours, when temperature rises to 170 DEG C, insulated and stirred, after viscosity index improver is all melted in base oil, add
Enter organic thickening agent, continue stirring of heating, when temperature rises to 180 DEG C, stop heating up, insulated and stirred, treat that organic thickening agent is complete
After portion is melted in mixing oil plant, adding antioxidant and be stirred for 0.5-1 hour, cooling down is to 50 DEG C～60 DEG C the most again, adds
Enter thickening agent, after abundant feed back stirs 1.5～2.5 hours, grind through homogenizing, vacuum outgas, finally give water white transparency shape glue
Body.
The invention has the beneficial effects as follows: mastic skeleton of the present invention is strong, thixotropic index is high, and high temperature drip is good, and has excellent
Colloid stability and oxidation stability, thermostability, weatherability, system regardless of oil, acid number little；It can make ribbon fiber at pine set
Pipe is interior and cable core can be in unstress state the most freely in cable all the time.Thus slow down optical fiber vibrations received, impact, protection
The performance of optical fiber is unaffected.
When this optical fiber filling paste is stressed, demonstrate that optical fiber is fixed motionless by the state that solid is the same；And work as
This stress is higher than (as by bending, make a dash and hit) during a marginal value, and filling paste will flow, and viscosity declines the most rapidly, this
Sample, fibre ribbon almost can just discharge these suffered stress while being stressed and without bending.And, because this
The thermodynamics phase tendency planting optical fiber filling paste is solid-state, so filling paste the most gradually reverts to semisolid after fibre ribbon is free
And fibre ribbon is fixed；Substantially increase the transmission quality of optical fiber ribbon cable.
The optical fiber filling paste product of the present invention is not required to heating when filling, play optical fiber ribbon cable well after filling optical fiber ribbon cable
Protection against the tide, the effect such as waterproof, shockproof, buffering, anti-high and low-temp, oversheath in fibre ribbon, optical cable is had the good compatibility.This product
Product processing technique is simple, and production environment cleans, pollution-free, water-resistance strong, and high temperature performance is excellent, is that novel environmental protection is produced
Product.
