Embodiment 1

[0012] The preparation method of the aramid fiber indoor optical cable reinforcing core of the present invention comprises the following steps: the aramid fiber is guided by a yarn guide plate, the multi-ply yarns are combined into one strand, and the temperature is entered into an oven at 200° C. for preheating for 2 minutes, and then Enter the immersion tank for impregnation. The immersion solution in the immersion tank includes 100kg of vinyl resin, 1kg of dibenzoyl peroxide, 2kg of tert-butyl peroxybenzoate, 3kg of silicone rubber and 10kg of aluminum hydroxide , and then use the preheated forming hole for molding treatment, and then enter the heating mold with a heating temperature of 150°C for heating and curing for 5 minutes, and then pull the reinforcing core out of the mold through the tractor. The tractor adopts the gap stop method and stops every 2 minutes. 7s, the traction speed of the tractor is 4m / min, to prevent the film from being blocked, and then to wind up, t...

[0014] The preparation method of the aramid fiber indoor optical cable reinforcing core of the present invention comprises the following steps: the aramid fiber is guided by a yarn guide plate, the multi-ply yarns are combined into one strand, and the temperature is entered into an oven at 230° C. for preheating for 2 minutes, and then Enter the immersion tank for impregnation, the immersion solution in the immersion tank includes 100kg of vinyl resin, 2kg of dibenzoyl peroxide, 3kg of tert-butyl peroxybenzoate, 2kg of silicone resin and 15kg of aluminum hydroxide , and then use the preheated forming hole for molding treatment, and then enter the heating mold with a heating temperature of 200°C for heating and curing for 4 minutes, and then pull the reinforcing core out of the mold through the tractor. The tractor adopts the gap stop method and stops every 3 minutes. 5s, the traction speed of the tractor is 5m / min, to prevent the film from being blocked, and then to wind up, th...

Embodiment 3

[0016] The preparation method of the aramid fiber indoor optical cable reinforcing core of the present invention comprises the following steps: the aramid fiber is guided by a yarn guide plate, the multi-ply yarns are combined into one strand, and the temperature is entered into an oven at 250° C. for preheating for 1 min, and then Enter the immersion tank for impregnation. The immersion solution in the immersion tank includes 100kg of vinyl resin, 3kg of dibenzoyl peroxide, 2kg of tert-butyl peroxybenzoate, 4kg of polytetrafluoroethylene and 20kg of hydrogen Aluminum oxide, and then use the preheated forming hole for molding treatment, and then enter the heating mold with a heating temperature of 250 ° C for heating and curing for 2 minutes, and then pull the reinforcing core out of the mold through the tractor. The tractor adopts the gap stop method, every Stop for 10 seconds after 4 minutes, the traction speed of the tractor is 6m / min, to prevent film blocking, and then rewi...

Abstract

The invention discloses an aramid fiber indoor optical fiber cable strengthening core preparation method which is characterized by comprising the following steps: carrying out yarn directing on aramid fiber by the use of a yarn directing plate, merging piled yarns into one string, entering an oven of 200-250 DEG C to preheat for 1-2min, entering an immersion trough for immersion, carrying out molding treatment by the use of preheat molded orifices, entering a heating die of 150-250 DEG C to carry out heat-curing for 1-5min, pulling out the strengthening core from the die by a dragger, and rolling, wherein an immersion liquid in the immersion trough contains: by weight, 100 parts of vinylite, 1-3 parts of dibenzoyl peroxide, 1-3 parts of tert-Butyl peroxybenzoate, 2-4 parts of a release agent and 10-20 parts of a filling material. The preparation method provided by the invention has the following advantages: the prepared strengthening core has low density, high strength, good flexibility and a certain rigidity; and if the strengthening core is broken, tensile strength of the strengthening core still remains more than 1400 Mpa.

Description
