Abstract
The invention provides a colourless transparent optical fiber ointment which comprises the components of (by weight ratio) base oil 75-90%, agglomerating agent 5-10%, anti-oxidant 0.1-1%, additive solution 10-20%, wherein the base oil is selected from mineral oil, synthesized oil and silicon oil, the additive is selected from EPT rubber, phenylethene-ethylen-propylene rubber segmented copolymer or their mixture, the additive is dissolved into synthesized oil with a concentration of 6-12%. The invention also discloses its preparation process.
Description
Technical field
The present invention relates to a kind of filling or coating material of communication cable, optical fiber ointment that especially a kind of optical fiber that is used in the optical cable coats and preparation method thereof.
Background technology
Optical cable is in the life-time service process, because the infiltration of moisture and moisture will cause the transmission performance deterioration of optical cable, even can not use.In order to prevent the invasion of moisture; and optical fiber phase mutual friction and damage optical fiber in making the optical cable process, except in the optical cable space, filling jelly---the optical cable ointment, also need on optical fiber, coat protection glue---optical fiber ointment; to guarantee optical fiber favorable mechanical performance, increase the service life.The development water resistance is good, and optical fiber itself do not have is corroded, can prevent the phase mutual friction again and damage optical fiber that construction technology is simple, and especially the optical fiber ointment that the transmission of light is not had an influence is the basis for preparing the high-performance optical cable.
Optical fiber ointment requires water white transparency, to reduce the influence to light transmission as far as possible; Temperature profile requirement to optical fiber ointment is not drip, not hardening of low temperature of high temperature, therefore, requires optical fiber ointment to have higher dropping point, separating of oil little, possesses good cone penetration performance simultaneously again; On the other hand, consider from the angle of fill process, require optical fiber ointment to have thixotropy, promptly ought be subjected to external energy (as shearing) and do the time spent, viscosity degradation takes place to soften and presents flowability, rises and just begin viscosity after externally energy stops.At present, mainly concentrate on both at home and abroad and develop high performance cold filling thixotropy optical fiber ointment, because the part index number of domestic research product is undesirable, most of domestic optical fiber factory still adopts the optical fiber ointment of high price import.
Summary of the invention
The object of the invention provides a kind of dropping point height, cone penetration is big, thixotropy good, separating of oil little, colourless transparent optical fiber ointment that high temperature performance is good.
Another object of the present invention provides the preparation method of this optical fiber ointment.
For achieving the above object, the technical solution used in the present invention is: a kind of colourless transparent optical fiber ointment comprises following component, be by weight percentage, base oil 75-90%, jelling agent 5-10%, oxidation inhibitor 0.1-1%, additive solution 10-20%, wherein, described base oil is selected from mineral oil, synthetic oil and silicone oil, and described additive is selected from terpolymer EP rubber, vinylbenzene-ethylene-propylene rubber(EPR) segmented copolymer or its mixture, additive is dissolved in the synthetic oil, and concentration is 6-12%.
In the technique scheme, described synthetic oil is a poly-a-olefin oil.The consumption of described additive is relevant with the realization of the object of the invention, additive product very little is separating of oil big, separating of oil and synersis appears, gelatin phenomenon appears in ointment, the solid-liquid phase-splitting, some places will not have ointment in the optical fiber loose tube, and some places are ointment caking then, and the optical fiber in the loose sleeve pipe will be subjected to uneven stress and cause the rapid increase of microbending loss; Then product strength is big too much for additive, can't insert in the optical fiber pine cover, also can increase cost simultaneously.
In the technique scheme, described jelling agent is an aerosil; Described oxidation inhibitor is selected from alkylphenol and arylamine.
For reaching another goal of the invention of the present invention, the technical scheme that adopts is: a kind of preparation method of colourless transparent optical fiber ointment, in base oil, add and be dissolved in base oil, concentration is the additive of 6-12%, under 100-130 ℃, heated while stirring 1-2 hour, be cooled to 50-80 ℃, add oxidation inhibitor, continue to stir, to be cooledly to room temperature, add jelling agent, stirred 1-2 hour with 60-80 rev/min stirring velocity, vacuumize again, obtain described optical fiber ointment, wherein, described additive is selected from terpolymer EP rubber, vinylbenzene-ethylene-propylene rubber(EPR) segmented copolymer or its mixture.
Further technical scheme before in the end vacuumizing, is carried out at least 2 roll-ins with three-roll grinder earlier.
Because the technique scheme utilization, the present invention compared with prior art has following advantage:
1. the present invention solves dropping point, separating of oil problem by adding additive, and by adding the additive of appropriate amount, optical fiber ointment not only has high dropping point, and cone penetration is big, and is separating of oil little.
2. the present invention comes the synthetic fibre-optical ointment by free special process condition and technological line, and its technology is simple, and is with short production cycle, and product performance are good.
