Problems solved by technology

This process must be completed by heating in the mold, so the production speed is low, only about 5 meters per minute
KFRP surface coating requires a special plastic coating production line for plastic coating production, and the cost of use is high

Embodiment 1

[0019] Such as Figure 1-2 As shown, the reinforcing member for thermoplastic GFRP butterfly cable of the present invention includes a body 1 , the body 1 is a round rod bonded by glass fiber and resin glue, and the surface of the body 1 is coated with a plastic coating layer 2 .

[0020] The production process of reinforcing parts for thermoplastic GFRP butterfly optical cable. Multiple glass fibers are released from their own active pay-off racks, and pass through the yarn guide frame that can guide the glass fibers into the center of the molding mold. The glass fibers are surface treated through a solvent-impregnated resin hopper. The hopper The inner temperature is 60°C, the glass fiber in the hopper passes through the immersion of the alcohol-soluble nylon resin solution in the hopper at a constant speed of 40 m / min, is dried in a drying tunnel at a temperature of 120°C, and then enters the extrusion mold through the guide holes of the extrusion molding mold. Out of the m...

Abstract

The invention discloses a reinforcement for a thermoplastic GFRP (Glass Fiber Reinforced Polymer) butterfly cable and a production process of the reinforcement. The reinforcement for the thermoplastic GFRP butterfly cable is characterized by comprising a reinforcement body, wherein the reinforcement body is a round rod formed by adhering glass fiber and thermoplastic resin, and a plastic-coated layer is coated on the surface of the reinforcement layer. The production process of the thermoplastic GFRP butterfly cable comprises the steps of: letting the glass fiber out, guiding in and forming, processing the surface, drying in a drying tunnel, secondarily dipping resin adhesive, cooling for forming, air-cooling to room temperature, coating the plastic-coated layer, water-cooling in a water trough, mold-stripping and then blowing, dragging, rolling a tension tower, winding on a rolling rack and completing all production processes of the reinforcement so that the reinforcement of the thermoplastic GFRP butterfly cable is obtained. The reinforcement has the advantages of minimum bending radius of not more than 10D(material diameter), tensile strength of not less than 1100Mpa, elongation at break of not more than 4 percent, tensile modulus of not less than 50Gpa, high production speed, low use cost and high cost performance.

Description

technical field [0001] The invention relates to the field of optical cable materials, in particular to a reinforcing member for a thermoplastic GFRP butterfly optical cable. [0002] The invention relates to the field of optical cable materials, in particular to a production process of a reinforcing member for a thermoplastic GFRP butterfly optical cable. Background technique [0003] FRP fiber optic cable strength member is an indispensable fiber optic cable strength member for non-metallic fiber optic cables and butterfly cables for FTTH. Although the thermosetting KFRP fiber optic cable strength member currently used has a small bending radius, the reinforcing material used is expensive aramid fiber, which is poor in cost performance. . The small bending radius of another thermosetting GFRP cannot meet the small bending performance requirements of the butterfly cable. The production process of thermosetting KFRP and GFRP optical cable reinforcement is a typical FRP pult...
