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 4-7kg of montmorillonite, 13kg-25kg of photocurable resin and 75-87kg of fiber yarn, first place the montmorillonite in a thermostat at 100-130°C to bake for 4-5 hours, then place the montmorillonite Put the stripping stone and light-curing resin into the mixer and mix evenly, then put it in a constant temperature box at 70-90°C for 1-2 hours, then put the montmorillonite, light-curing resin and fiber yarn into the solution tank and mix evenly, and then pass the pull The extrusion die is pultruded to form a shaped rod, and finally the shaped rod is placed in an ultraviolet curing furnace for 0.1 to 12 seconds to cure, and the fiber-reinforced plastic referred to in the present invention can be obtained. In this embodiment, 5.5 kg of montmorillonite, 20 kg of photocurable resin, and 80 kg of fiber yarn are preferably selected. The montmorillonite is placed in a constant temperature box and the baking temperature is preferably 115 ° C. The baking time is 4....

Abstract

The invention relates to a preparation method of a fiber-reinforced plastic of an outdoor system and an indoor system of the fiber-to-the-x (FTTx) network engineering in a communication network. The preparation method of the fiber-reinforced plastic comprises the following steps of: a) placing montmorillonite in a 100-130 DEG C thermostat to bake for 4-5h; b) placing montmorillonite and photocurable resin in a mixer to mix evenly, and placing the mixture in a 70-90 DEG C thermostat to keep the temperature for 1-2h; c) placing montmorillonite, photocurable resin and fiber yarn in a solution tank to mix evenly; d) performing pultrusion by using a pultrusion mould to obtain a moulded rod piece; and e) placing the moulded rod piece in an ultraviolet curing furnace to cure for 0.1-12 seconds. By adopting the fiber-reinforced plastic prepared by the preparation method, the safety protection performances of communication facilities and user terminal equipment can be increased; and particularly, the cable diameter is small and the curvature radius is small, and the special requirements of the FTTx network engineering, namely easy branching, easy accessing and convenient construction can be met.

Description

technical field [0001] The invention relates to a communication material, in particular to a preparation method of fiber-reinforced plastic for an outdoor system and an indoor system of an optical fiber access (FTTx) network engineering in a communication network. Background technique [0002] At present, the optical cables for transmitting communication signals mainly use quartz glass optical fibers, and all of them adopt the reinforcement measures of coating resin on the surface of bare fibers. Since the material of the resin coated on the surface of the bare fiber has a defect of very low tensile strength, in order to improve the tensile strength of the optical cable, several strengthening members are added around the optical fiber. 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 larg...
