Embodiment 3

[0020] The immersion solution in the immersion tank includes organosilicon high temperature resistant resin, the additives are 10% curing agent, 11% tert-butyl fat, 10% release agent, 26% stearic acid and 43% light calcium carbonate, and the temperature is 140 ℃-160℃ resin mixture, the ratio of silicone high temperature resistant resin and additive is 3.5:1.

[0021] The production method of the FRP fiber optic cable reinforcing core of the present invention uses the improvement of the mold to improve the production efficiency. The trumpet-shaped heating mold has small friction force, which can increase the traction speed, and the heat dissipation of the molding is faster. The final shape is still fixed by using an ordinary straight mold for reinforcement. Stablize.

[0022] A section of parallel passages is arranged behind each section of the trumpet-shaped passage to facilitate the shaping of the outer diameter.

[0023] As the outer diameter gradually shrinks, the size of ...

Abstract

The invention discloses a production method of a reinforced FRP (Fiber Reinforced Plastic) optical cable core, which comprises yarn unwinding, yarn guiding, heating curing, drawing and winding. Glass fiber yarns are unwound, guided and twisted to form multi-ply glass fiber yarns, the multi-ply glass fiber yarns are woven into linear net, and the linear net is immersed in an immersion trough and then enters heating dies, wherein at least three heating dies are arranged, the curing temperature is increased gradually, the first two or three of the heating dies are flared, the inlet diameters of the flared heating dies are greater than the outlet diameters of the flared heating dies, and the inclination angles of the flared heating dies are 1-5 degrees. According to the production method of the reinforced FRP optical cable core, the production efficiency is increased by virtue of improvements on the dies; the flared heating dies have small friction forces, can increase the drawing speed and are quick in forming and cooling; and the reinforced FRP optical cable core is finally shaped by common straight-tube-shaped dies to be reinforced and stabilized.

Description

technical field [0001] The invention relates to the technical field of optical cables, in particular to a method for producing a reinforcing core of an FRP optical cable. Background technique [0002] The fiber optic cable strength core plays a vital role in protecting the fiber optic cable in the structure. Reinforcing cores are generally divided into metal reinforcing cores and non-metallic reinforcing cores. Commonly used metal reinforcement cores are single steel wire and steel strand. Non-metallic cores are commonly used in two types: fiber reinforced (FRP) and aramid yarn (KF), which are generally used for power cables. between. [0003] The structural strength of the optical cable is an important indicator of the mechanical properties of the optical cable. As one of the structural components of the fixed optical cable, the strengthening core plays a major role in enhancing the tensile and compressive capabilities of the optical cable. [0004] As a structural stre...
