Abstract

The invention discloses a fiber optic cable strengthening core, which is obtained by solidifying and compounding resin coating liquid and aramid fiber, wherein the organic resin coating liquid raw materials include: hydroxylated nano-boron nitride, isocyanate group-terminated water-based polyurethane Prepolymer, bismaleimide, solvent, catalyst, and release agent; wherein, the hydroxylated nano-boron nitride contains furan functional groups. The present invention also proposes a method for preparing the reinforcing core of an optical cable, which includes the following steps: preheating the aramid fiber at 180-220°C for 2-5 minutes, then soaking in the resin coating liquid, heating and curing the optical cable through a forming mold Strengthen the core. The present invention adds a resin layer on the surface of the traditional aramid fiber reinforced core, and the resin layer is obtained through the reaction of hydroxylated nano-boron nitride and isocyanate group-terminated water-based polyurethane prepolymer, which improves the self-repairing performance of the reinforced core material and prolongs the strength of the reinforced core. The service life of the core and the performance of the cable.

Description

technical field [0001] The invention relates to the technical field of optical cables, in particular to an optical cable strengthening core and a preparation method thereof. Background technique [0002] The fiber optic cable reinforcement core is an important component of the communication cable. The traditional reinforcement core is mainly phosphating steel wire. In humid air, corrosion of metal components and biochemical corrosion will produce hydrogen evolution, which will affect the signal transmission function. In addition, the processing cost of steel wire and optical fiber into optical cable is relatively high, and the mechanical and corrosion resistance properties are not stable enough. In recent years, non-metallic optical cable central reinforcements have been gradually applied and popularized. Compared with traditional phosphating steel wire reinforced cores, fiber-reinforced composite optical cable reinforced cores have the characteristics of light weight, corr...
