Abstract
The invention relates to a water-repellency cold application filling paste used in an optical cable. The paste mainly comprises: a base oil, an adhesion promoter, a oil separating inhibitor, a gelling agent, an antioxidant, a thickening agent and an anti-emulsion agent. The invention also provides a preparation method. By using the water-repellency cold application filling paste, the optical cable can have characteristics of water blocking, moisture protection, pressure resistance, buffer and the like under any environments and any climate conditions. And the filling paste also can bear a high/low temperature, have good resistance to saline water, demulsify (80 DEG C, 7d, with no emulsification and no disassembly), and possess a high thixotropic index value and the other characteristics. The filling paste can be used to fill in an air gap in various optical-cable loose sleeve or fill in combination of the above structure and other gaps of an optical cable element so as to prevent water or other fluids inflow or move to the optical cable. The water blocking, the moisture protection, the pressure resistance, the buffer and the like effects are provided for the optical cable so as to improve quality of an optical cable product.
Description
Technical field
The present invention relates to a kind of optical cable with cold-application filling paste and preparation method thereof, relate in particular to a kind of optical cable with refusing water type cold-application filling paste and preparation method thereof.
Background technology
Because the difference of cable configuration and environment for use; Also different to cable cream performance demands; At home Chinese-foreign joint unit (as: SUMITOMO CHEMICAL electrician, Korea S's Hainan Samsung, Dutch Twentsche(nanjing)fibre optics ltd. etc.) particularly; The order that they produce is main with outlet mainly; The structure of these optical cables and domestic different is showing mainly aspect the cable cream that it refuses water type rather than imbibition type to the requirement of cable cream, and the water penetration test of optical cable is (optical cable of domestic use generally stops the optical cable infiltration through imbibition type cable cream) of realizing through the water repellency of cable cream.
Above-mentioned two kinds of methods have essential distinction, stop optical cable infiltration with refusing water type ointment, will reach more than 95% the filling plumpness of optical cable, and it requires very high to the fill process of optical cable; And come filled fiber cable to stop the optical cable infiltration with imbibition type ointment, as long as reaching more than 70%, the filling plumpness just can accomplish the end in view.But from the quality aspect of protection optical cable, the former is better than the latter; Because latter's (imbibition type cable cream) is once be exposed in the air will moisture absorption moisture absorption; Though can play resistance effect to optical cable, cable cream is once imbibition, and local optical cable will soak in the cable cream after suction for a long time; As time goes on, will produce unfavorable factor to the quality of optical cable.
Along with the continuous increase of domestic optical cable producer outlet optical cable quantity, developing a kind of cold application optical cable of water type filling paste of refusing is one of those skilled in the art's direction of being devoted to study.
Summary of the invention
The object of the invention; Provide a kind of optical cable with refusing water type cold-application filling paste to the problems referred to above exactly; Thereby thoroughly solve infiltration and the protection question of optical cable under various natural environment and climate conditions,, thereby improve the optical cable product quality with the transmission performance of assurance optical cable.
Another object of the present invention is to provide a kind of above-mentioned optical cable with the preparation method who refuses water type cold-application filling paste.
The technical scheme that the present invention is adopted in order to reach the goal is: a kind of optical cable comprises following feed composition and weight percent content thereof with refusing water type cold-application filling paste:

Antioxidant 0.3～1%;
Thickening agent 8～30%;
Anti-emulsion 0.2～3%.
Above-mentioned optical cable is with refusing water type cold-application filling paste, and wherein, said base oil is selected from hydrogenation white oil or naphthenic rubber oil; Said tackifier are selected from polyisobutylene; Said oil dividing inhibitor is selected from the high molecular polymer synthetic rubber, and said viscosifying agent is selected from the macromolecular thermoplastic synthetic rubber, and said antioxidant is high-temperature antioxidant; Said thickening agent is an extreme pressure water-resistant railway grease, and said anti-emulsion is the special-purpose anti-emulsion of lubricated oils.
Above-mentioned raw materials is the commercially available prod.
The present invention also provides a kind of above-mentioned optical cable with the preparation method who refuses water type cold-application filling paste, may further comprise the steps:
Earlier tackifier are added in the base oil, heated and stirred added oil dividing inhibitor after 0.5～1 hour, continued heating and stirring 2～5 hours; When treating that temperature rises to 150 ℃, add viscosifying agent, continue heating and stirring, insulated and stirred when treating that temperature reaches 170 ℃; All be melted in the base-material until viscosifying agent, add antioxidant then, fully stir 0.5～1 hour after, base-material cooling is cooled to 20 ℃～60 ℃; Add thickening agent, fully feed back stirred after 1～3 hour, added anti-emulsion, fully stir 0.5～1 hour again after; Obtain the faint yellow compound of semifluid shape, grind through homogeneous, vacuum outgas obtains final products.
Core technology of the present invention is to adopt material, particularly viscosifying agent and the thickening agent with demulsification performance, and it can guarantee infiltration and the protection question of optical cable under various environment (particularly optical cable under the deep water, the common cable cream that blocks water is difficult to meet the demands) and weather conditions.Viscosifying agent in the present invention prescription adopts is the thermal plastic high polymer synthetic rubber that has splendid water repelling property after oil-filled.What thickening agent adopted is the railway grease with extreme pressure water-resistant performance.And the thickening agent of common cable cream mostly adopts as: bentonitic clay, SIO
2, AL
2O
3Deng material, these materials under certain condition (as: temperature, pressure etc.) very easily by emulsification.
The present invention makes it have following advantage and characteristics owing to adopted above technological innovation scheme:
1, optical cable of the present invention is to stop various liquid through self water repellency with refusing water type cold-application filling paste; It is inner that gas and external foreign material are invaded optical cable; Be the imperial bodyguard next to the shin who truly protects optical cable, it can thoroughly solve phenomenons such as optical cable blocking water under any natural environment and climate condition, protection against the tide, resistance to compression, buffering thus.
2, optical cable of the present invention has high-low temperature resistant, salt water resistance, emulsion resistance (80 ℃, 7d, not emulsification is not disintegrated), the high characteristic of thixotropic index value with refusing water type cold-application filling paste;
