Embodiment 1

[0032] An all-dielectric self-supporting anti-galvanic coating for optical cable jackets, the main component of which is silicone resin, and the auxiliary component is carbon black; the carbon black accounts for 1% of the mass percentage of the prepared silicone resin, which is used to adjust coating resistance.

[0033] A preparation method of an all-dielectric self-supporting optical cable jacket anti-electrocorrosion coating The specific operation steps are as follows:

[0034] First, slowly add 22.0g of HCl aqueous solution (0.01mol / l, pH=2) to 71.2g of methyltriethoxysilane, at 60 oC under stirring for 3h to obtain a uniform transparent silicone resin sol. Then add 8.0 g of hydroxyl-terminated silicone resin (molecular weight is about 700) with a mass fraction of 30% to prepare a silicone resin mixture. 0.27g of carbon black was added to the above mixture, and a uniform silicone resin / carbon black initial slurry was prepared by ball milling. Finally, add 0.27 g of curi...

Abstract

The present invention relates to the technical field of novel coating preparation, particularly to an all-dielectric self-supporting optical fiber cable jacket electrical erosion resistance coating material and a preparation method thereof. The coating material comprises a main component organosilicon resin and an auxiliary component carbon black, wherein the amount of the carbon is 0.5-2.5% of the mass of the organosilicon resin precursor, and the carbon black is provided for adjusting coating resistance. According to the present invention, the main component of the coating material is the silicon resin, the auxiliary component is the carbon black, the silicon resin has excellent insulating property, water repellency, high temperature resistance and low temperature resistance, and the carbon black can be provided for adjusting the resistance value of the silicon resin to the required range (volume resistivity 104-107 omega / m) and avoiding dry strip arc generation on the surface of the ADSS optical fiber cable so as to provide a electrical erosion resistance effect; and the preparation method is simple, and the coating has strong operability.

Description

technical field [0001] The invention relates to the technical field of novel coating preparation, in particular to an all-dielectric self-supporting anti-electrocorrosion coating for an optical cable jacket and a preparation method thereof. Background technique [0002] With the rapid development of electric power construction and power grid construction, the backbone optical cable communication network of electric power communication has also begun to form, which will undertake power system production scheduling, production management, scheduling automation, electricity billing, computer data, line protection, video conference and graphics Transmission and other information, signal transmission. It is a very economical means of laying optical cables by using overhead power line corridors and overhead on line towers. At present, there are two main ways to lay optical cables overhead on line towers: the use of optical cable composite overhead ground wires (OPGW) on new 110 k...
