Problems solved by technology

In the prior art, the optical fiber is arranged in the loose tube, and at the same time, fiber paste is added to the loose tube. The fiber paste is indispensable in the production of central tube type and layer-stranded optical cables, and plays a role of sealing, stress resistance and buffering function, but it does not have the effect of heat insulation; in the prior art, in order to combine the optical fiber and the transmission line, the market has begun to develop the optical fiber transmission cable, which combines the optical cable and the transmission cable, but because the electric wire in the transmission cable is in the In the process of transmitting current, it is necessary to overcome its own resistance and generate a lot of heat, so the heat will affect the transmission performance of the optical fiber, so the existing power transmission optical cable needs to overcome the above important problems

Abstract

The present invention discloses an optical fiber surface coating adhesive, which consists of the following raw materials in parts by weight: 25 to 30 parts of organosilicone rubber; 5 to 10 parts of high molecular weight polyisobutylene; 5 to 10 parts of medium molecular weight polyisobutylene; 10 to 15 parts of low molecular weight polyisobutylene; 10 to 15 parts of inorganic filler; 0.5 to 1 part of an antioxidant; 5 to 10 parts of glass fiber; and 5 to 10 parts of silicate.

Description

technical field [0001] The invention relates to an optical cable structure, in particular to coating glue on the surface of an optical fiber. Background technique [0002] Optical cable is a light transmission tool that achieves the principle of total reflection of light in fibers made of glass or plastic. An optical cable is a communication line in which a certain number of optical fibers form a cable core in a certain way, and is covered with a sheath, and some are also covered with an outer sheath to realize optical signal transmission. In the prior art, the optical fiber is arranged in the loose tube, and at the same time, fiber paste is added to the loose tube. The fiber paste is indispensable in the production of central tube type and layer-stranded optical cables, and plays a role of sealing, stress resistance and buffering function, but it does not have the effect of heat insulation; in the prior art, in order to combine the optical fiber and the transmission li...
