Embodiment Construction

[0021] A preparation method for a glass fiber reinforced plastic cable protection tube, comprising the following steps:

[0022] The first step, the preparation of equipment, said equipment comprises winding machine and auxiliary equipment;

[0023] The second step is the preparation of the core mold. According to the cable protection tube, select the seamless steel pipe of the corresponding size as the blank of the core mold, use the cylindrical grinder to grind the surface of the core mold, and then use the polishing machine to polish the outer surface of the core mold. treatment, so that the roughness Ra of the surface of the mandrel reaches 1.6 μm, wipe the surface of the mandrel with absolute ethanol and dry it, apply a layer of release agent on the surface of the mandrel, and finally install the mandrel on the core of the winding machine on the module driver;

[0024] The third step is the preparation of materials. The materials required for preparation include glue and...

Abstract

The invention discloses a preparation method of a glass fiber reinforced plastic cable protection tube. The preparation method comprises preparation of equipment, preparation of a core mold, preparation of glue solution, preparation of fibers, winding forming, curing, demoulding, surface finishing and the like. According to the glass fiber reinforced plastic cable protection tube, alkali-free glass fiber is adopted as a reinforcing material, epoxy resin is used as a matrix, and the raw material cost is low; the glass fiber reinforced plastic cable protection tube is prepared by fiber winding,so that the mechanical automation degree is high, and the production efficiency is high; and compared with a metal steel tube, the prepared glass fiber reinforced plastic cable protection tube is light in weight, high in strength, good in toughness, excellent in corrosion resistance and electrical insulation performance, and long in service life, and can be safely applied to a power transmission line and telecommunication line dense area.

Description

technical field [0001] The invention relates to a preparation method of a cable protection fitting, in particular to a preparation method of a glass fiber reinforced plastic cable protection tube. Background technique [0002] In municipal construction, a large number of power transmission cables are buried underground, and the power transmission cables are easily damaged under the erosion of soil, etc. At this time, a kind of pipeline is needed to protect the cables. The cable protection pipes currently used mainly include steel pipes, PVC pipes, cement pipe etc. Although these pipes can protect cables to a certain extent, there are still some problems in actual use, such as high price of steel pipes, heavy weight, inconvenient installation and transportation; the strength of PVC pipes is low, and when used for cable protection, It is necessary to build a concrete protective layer around it to enhance the strength, and the construction period is long and troublesome; the c...
