Problems solved by technology

The traditional fiberglass cable strength core has the advantages of cheap price, corrosion resistance, antistatic, etc., but the minimum bending radius is large, the strength and modulus are low, and it is easy to break in actual use.
The reinforced core of aramid optical cable is light, high-strength and high-modulus. However, due to the high price of aramid fiber, and its source mainly depends on limited imports from abroad, it is difficult to achieve large-scale use. Therefore, the application of aramid fiber in the domestic optical cable market has been limited to In smaller fields, for this reason, optical cable manufacturers have always hoped to find fiber optic cable reinforcement core materials with higher strength, stronger toughness, and lower cost to meet the development needs of the domestic optical fiber market.

Abstract

The invention discloses a basalt fiber optical cable reinforced core and a manufacturing method thereof and belongs to non-metal compound fiber optical cable reinforced cores. The reinforced core is formed by curing and compounding organic glue solution and basalt continuous fibers. The reinforced core produced by extruding the continuous basalt fiber has high insulation performance and high magnetic prevention and fire resistance performance; the breaking strength of the reinforced core is greater than that of an aramid fiber by 10 to 15 percent, and the modulus of the reinforced core is close to that of the aramid fiber; the reinforced core can replace the aramid fiber only adopted in high-grade optical cables, and the cost of the reinforced core is lower; and the reinforced core can meet the requirement on comprehensive optical-fiber-to-door development in China. The basalt fiber optical cable reinforced core has simple components and the efficiency of the production method for thebasalt fiber optical cable reinforced core is higher; the basalt fiber optical cable reinforced core is suitable for industrial large batch production and is easy to popularize.
