Problems solved by technology

Under the action of moisture, moisture and stress, the optical fiber will produce stress corrosion, and hydrogen damage will occur in a hydrogen-containing environment; once the optical fiber is subjected to stress, corrosion and hydrogen damage, the transmission performance of the optical cable will be greatly reduced. As time goes by, the optical cable will gradually lose its information transmission performance. The consequences of this phenomenon on society can be imagined. It will not only bring great inconvenience to people's daily life and work, but will also have serious consequences for national construction influences

Abstract

The invention discloses an optical cable GTL base oil filling paste. The optical cable GTL base oil filling paste is mainly composed of GTL base oil, oil decomposition inhibitor, thermoplastic synthetic rubber, antioxidant and thickener. The invention further discloses a preparing method of the optical fiber GTL base oil filling paste. The optical fiber GTL base oil filling paste has the advantages of being low in density, good in low-temperature performance and capable of being safely used as factice products for replacing synthetic oil in an environment of minus 50 DEG C, having good colloid stability, oxidation stability, heat resistance and weather resistance and being system-oil-decomposition-free in system and low in acid value; being high in thixotropic index, low in viscosity, strong in water-resistance, emulsification-free, good in high temperature drip, wide in environment temperature application range, and enabling an optical fiber to be always in a stress-free state inside a buffer tuber and a cable core to be always in a stress-free state inside a cable.
