Description
Technical field
The present invention relates to the packing material of a kind of optical cable, be specifically related to a kind of cold application waterproofing type optical cable filling paste and manufacture method thereof.
Background technology
In recent years, development and application with communication electricity (light) cable, their long-term reliability is increasingly subject to people's attention, electricity (light) cable is during long-term use, erosion due to moisture and moisture, transmission performance is caused to decline, impact is normal to be used, people have passed by first generation maintenance by gas pressuriztion to the hot factice for filling of the second generation in the research of this block, finally arrive the use of the cold factice for filling of the third generation, but filling paste is as the important step in electricity (light) cable production, its performance indications directly influence the quality of cable, for example: it is to examine the quantity that oil is separated from filling paste at a certain temperature that the oil of filling paste separates, if oil separates excessive, then in use oil easily drips from cable core；Owing to filling paste containing many acidic components, if acid excessive, then impact, such as oxidation, corrosion etc. are produced on adjacent material；The chargeding performance of filling paste molecule, directly influences the electric conductivity of cable；And viscosity should have shear thinning function, i.e. the viscosity of filling paste declines with the rising of shear rate, generally, viscosity is i.e. difficult to excessive, is not easy to too small, because in process, wish that viscosity is little, it is simple to insert in cable core, but viscosity is too little, then process when filling paste be easy to run off, do not have the effect of buffering when cable core stress, and if viscosity is excessive, affect freely stretching of cable core, be easily generated stress and concentrate, cause bending loss, so filling paste in the market, very different.
