Organic silicon dehydrogenation condensed type optical cable adhesive and use method thereof

Abstract

The invention relates to a dehydrogenation condensed type optical cable adhesive and a use method thereof. The A component substance of the adhesive is a sizing material obtained by the steps of taking hydroxy-terminated polydimethylsiloxane as a basic polymer, adding polymethyl hydrogen siloxane and fumed silica and mixing evenly; and the B component substance of the adhesive is an organic tin curing agent prepared by dissolving dibutyltin dilaurate in 120# solvent gasoline or petroleum ether. When in use, the A component substance of the sizing material is dissolved in the 120# solvent gasoline or the petroleum ether with the boiling range of 90 to 120 DEG C in advance, then the mixture is coated on the surface of an optical cable by brush coating or dip coating after the solution and the curing agent are mixed evenly, and an optical cable winding is prepared by winding after curing. The adhesive has moderate bonding strength, ageing resistance and high / low-temperature resistance, the inherent shape of the bonded optical cable winding can keep stable in the processes of storage, transportation and paying off, the resistance generated when the optical cable winding is paid off athigh speed is also minimum without the deviation of the coils of the optical cable, and the signal transmission of the optical cable is also not influenced.

Description

technical field [0001] The invention relates to a silicone optical cable adhesive, in particular to a dehydrogenation condensation optical cable adhesive and its application method. The adhesive can not only be used for the bonding and setting of optical cable windings, but also is easy to untie and can meet the requirements of high-speed payout, so it is especially suitable for long-distance optical cable transmission fields, such as communications, meteorological department sounding balloon control, signal transmission and High-tech applications such as traction and throwing across obstacles, as well as the field of defense wired guidance. Background technique [0002] As far as the optical cable adhesive with silicone material as the main body is concerned, the DC-1-2577 used in the United States is a one-component solvent-type room temperature vulcanizing silicone resin with medium viscosity, and the cured product has high hardness and high strength. When used for the b...
