Embodiment 1

[0042]30.5% of 36 by weight percentage at normal temperature # Hydrogenated white oil, 40% PAO-8 synthetic oil, 10% PriECO-3002 polyol ester and 0.5% Lc-212 viscosity index improver were stirred and mixed for 20 minutes. Add 0.5% additive OB optical brightener, 10% BP2400 oil separation inhibitor and 2% oil separation inhibitor G1702, heat up and stir, the temperature is controlled at 200°C ± 5°C, and then add 4% organic thickener Fumed silica H 20 Heat and stir, control the temperature at 200°C±5°C, add 0.5% antioxidant AT-215 and 2% inorganic thickener SOP.1650, keep warm and stir, control the temperature at 200°C±5°C, - Homogenized shearing for 60 minutes, recycling, cooling to room temperature, ≤60°C. Homogenize and degas for one hour (vacuum pressure ≥ 0.07Mpa) and filter with a 200-mesh filter to obtain the required OPGW fiber filling paste.

Abstract

A filling grease for composite fibre-optical overhead earth wire is prepared by mixing 36®|hydrogenated white oil and PAO-8 synthesized oil with PriCO-3002 polybasic alcohol ester and viscosity exponential improver Lc-212, adding into additive OB fluorescent brightening agent, grease-separating inhibitor BP2400 and G1702, raising temperature, stirring, adding into organic thickening agent gas-phase carbon white H20, raising temperature, thickening, adding into antioxidant AT-215 and inorganic thickening agent SEP1650, raising temperature, thickening, shearing, circulation feeding back, cooling to normal temperature, homogenizing, degassing, filtering and obtaining the grease. It achieves good hydrogen absorption and stable fibre-optical transmitting performance.

Description

technical field [0001] The present invention relates to a kind of filling ointment for optical cable, more specifically, the present invention relates to a kind of filling ointment for OPGW (optical composite overhead ground wire) optical fiber. Background technique [0002] In recent years, the power communication business has been greatly developed. The power communication mainly relies on the power grid, and the optical communication medium is used for transmission. There are two main forms: one is laid on the existing high-voltage transmission line or newly built lower The ADSS optical cable on the transmission line of the voltage level; the other is the optical fiber composite overhead ground wire (OPGW) which is mainly laid on the high-voltage transmission line and integrates the functions of optical fiber communication and overhead ground wire. OPGW optical cable has been widely used for its excellent optical transmission performance (low loss, wide transmission frequ...
