Abstract
A water-resistant oil cream for optical cable is proportionally prepared from the special basic oil cream with high adaptibility and performance, the synthetic high-hydroscopicity resin as expansive material prepared from acrylic acid and its derivative, and the additive including gelatinizing agent.
Description
Technical field
The present invention relates to a kind of filling or coating material of communication cable, especially a kind of greasy for preventing water that is used for the optical cable filling.
Background technology
Sealing optical fiber cables water resistance quality will directly have influence on transmission stability, reliability and the work-ing life of optical fiber and optical cable.In order to prevent the invasion of moisture, and the influence of mechanical force such as the buffered optical fibers phase mutual friction that may be subjected to, vibration, impact, bending, need be in the optical cable space filled fiber cable ointment.
Traditional ointment adopts the hydrophobic ointment of thixotropy usually, as Shi Xiaodong in " chemistry world " 1996 the 8th phases, the 115-118 page or leaf has been reported a kind of optical fiber, optical cable thixotropic filling paste, because this ointment is filled between optical fiber cable, utilize the hydrophobicity of material itself to reach the purpose that blocks water, so block-water effect is poor.Yet China still adopts this class ointment at present in a large number.Also there is minority to adopt the hot-melting type ointment in addition, comprise Vaseline foundation stone ointment or rubber-type vaseline, this series products needs high temperature to fill, technology controlling and process is very complicated, bigger to the person and environmental pollution, and high temperature has been accelerated plastics when filling degradation speed and the low seed oil that divides are moved to ability in the plastics, influence the use properties of optical cable.
For guaranteeing sealing optical fiber cables, improve the block-water performance of optical cable ointment, people begin one's study and add material water-proof material in ointment.For example, Chinese invention patent application CN1451728A discloses a kind of communication optical cable and electric cable filled factis, has promptly added the waterproofing agent of 11%-12% in former base oil component, attempts to increase by the expansion soaking effect of waterproofing agent the block-water performance of optical cable ointment.Yet the waterproofing agent that it adopted is commercially available expanding powder, itself is not designed for the optical cable ointment, with the existing problems that cooperate of basic ointment, is difficult to guarantee the cone penetration and the thixotropy of product, is difficult to satisfy the performance requriements of market to the optical cable ointment.
Summary of the invention
The present invention seeks to by to the cooperation adjustment of basic ointment, expanding material and the improvement of technology, provide a kind of dropping point height, cone penetration is big, thixotropy good, absorption speed is fast, separating of oil little greasy for preventing water on cable.
For achieving the above object, the technical solution used in the present invention is: a kind of greasy for preventing water on cable, mainly be made of basic ointment component, expanding material component and additive, wherein, described basic ointment component comprises, by weight percentage, synthetic oil 50-60%, anti-sagging agent solution 30-40%, polymeric additive solution 15-20%, wherein, anti-sagging dose is selected from terpolymer EP rubber or silicon rubber; Polymeric additive is vinylbenzene-ethylene-propylene rubber(EPR) segmented copolymer, and solvent is a synthetic oil.
Described expanding material component is the cross-linking products by vinylformic acid, sodium acrylate and Hydroxyethyl acrylate, its acquisition process is, at first make acrylic acid aqueous solution and sodium hydroxide solution carry out neutralization reaction, degree of neutralization is 60-90%, add linking agent, initiator again, the following and Hydroxyethyl acrylate polymerization reaction take place of heating condition, all monomers account for the 60%-80% of total amount by weight percentage in the reaction solution, polymerization temperature is 50-80 ℃, reaction times 1-4 hour;
Described each components contents is by weight percentage, basic ointment 70-85%, and expanding material 14-20%, additive 8-15% in the described additive, comprises jelling agent 2-5%.
In the technique scheme, described basic ointment component can will resist sagging dose as (this only is the anti-sagging agent solution that is mixed with 5-10% in the terpolymer EP rubber adding synthetic oil, rather than basic ointment), the speed stirring with 60-80 rev/min obtained standby in 2-4 hour under 130-170 ℃; Described expanding material is a kind of super absorbent resin, and the super absorbent resin that is obtained by aforesaid method and the consistency of basic ointment are good, good combination property; In the described additive, except jelling agent, can also add oxidation inhibitor, thickening material etc. as required; For obtaining good performance, after described basic ointment, expanding material and additive mix, can be with repeatedly roll-in of three-roll grinder, stirred 1-2 hour with 50-70 rev/min speed again, vacuumize acquisition again.
In the technique scheme, described jelling agent is an aerosil.
Further technical scheme, described linking agent is selected from N ', N-methylene-bisacrylamide, glycol ether, glycerine, dosage of crosslinking agent is the 0.01%-0.06% of total monomer weight; Described initiator is selected from Potassium Persulphate, ammonium persulphate, S-WAT, sodium bisulfite, and initiator amount is the 0.02-0.1% of total monomer weight.
Because the technique scheme utilization, the present invention compared with prior art has following advantage:
1. the present invention adds additive in basic ointment, prepared basic ointment is compared with domestic thixotropy ointment commonly used, have and absorbent resin adaptability height, good combination property, advantage that cost is low, and can guarantee the oil of the greasy for preventing water that obtains, separate little, high temperature performance good, especially at low temperatures cone penetration height in the time of-40 ℃, ointment does not ftracture;
By vinylformic acid and derivative synthetic super absorbent resin thereof as the expanding material component, method is simple and feasible, suction intensity height, speed is fast, multiplying power is big, and basic ointment consistency good;
The product dropping point height that obtains of the present invention, cone penetration is big, thixotropy good, absorption speed is fast, can satisfy the requirement of optical cable water-blocking.
