Problems solved by technology

In addition, in order to meet the moisture-proof and water-proof performance of the optical cable, waterproof materials must be wrapped or filled around the optical fiber, so the manufacturing process is complicated, the cable diameter is large, the texture is heavy, the radius of curvature is large, the cost is expensive, and it is filled with waterproof ointment Easy to cause secondary pollution to the environment

Embodiment 1

[0004] Example 1: Take 13-25kg of light-curable resin and 75-87kg of fiber yarn, first put the light-curable resin in a constant temperature box at 70-90℃ for 1 to 2 hours, then put the light-curable resin and fiber yarn into the solution The tank is evenly mixed, pultruded into a shaped rod through a pultrusion die, and the shaped rod is placed in an ultraviolet curing oven for 0.1-12 seconds to obtain the fiber reinforced plastic in the present invention. In this embodiment, 20kg of light-curable resin and 80kg of fiber yarn are selected preferentially. The light-curable resin is placed in a thermostat and the thermostat temperature is 80°C and the thermostat time is 1.5 hours. The curing time of the molded rod in the ultraviolet curing oven is preferentially selected. 6 seconds.

Abstract

The invention relates to a method for preparing fiber reinforced plastics of an outdoor system and an indoor system of a fiber-to-the-x (FTTx) network project in a communication network. The method comprises the following steps of: a, putting light-cured resin into a constant temperature box at the constant temperature of between 70 and 90 DEG C for 1 to 2 hours; b, putting the light-cured resin and fiber yarns into a solution tank, and mixing uniformly; c, performing pultrusion by using a pultrusion die to form a formed rod piece; and d, putting the formed rod piece into an ultraviolet curing furnace, and curing for 0.3 to 12 seconds. By the method, the safety protective performance of communication facilities and user terminal equipment is improved; and particularly, a cable has a small diameter and a small curvature radius, and the special requirements of simplicity in branching and access and convenience for construction in the FTTx network project can be met.

Description

Technical field [0001] The invention relates to a communication material, in particular to a method for preparing fiber-reinforced plastics for outdoor systems and indoor systems of optical fiber access (FTTx) network engineering in communication networks. Background technique [0002] At present, the optical cables that transmit communication signals mainly use silica glass optical fibers, and all use the reinforcement measures of coating the surface of the bare fibers with resin. Since the resin coating the surface of the bare fiber has the defect of very low tensile strength, in order to improve the tensile strength of the optical cable, several reinforcements are added around the optical fiber. In addition, in order to meet the moisture-proof and water-seepage performance of the optical cable, it is necessary to wrap or fill the waterproof material around the optical fiber. Therefore, the manufacturing process is complicated, the optical cable is large in diameter, heavy in t...
