Abstract

PURPOSE:To provide a regenerating method for used plastic insulator. CONSTITUTION:The surface 8 of a used plastic insulator 1 is exfoliated. This insulator 1 is put in molding forms 10a, 10b which have a size greater than its embodiment before exfoliation and have a similarity in the shape. The forms 10a, 10b are filled with a plastic of the same material quality as the plastic constituting the insulator 1.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for recycling a synthetic resin insulator used for a transmission / distribution line.

[0002]

2. Description of the Related Art As shown in FIG. 2, a synthetic resin insulator 1 for an outdoor transmission / distribution line has a synthetic resin portion 2 made of silicon rubber or ethylene propylene rubber and metal fittings 3a, 3b at both ends.
It consists of As shown in FIG. 3, the synthetic resin insulator 1 is attached to an arm 6 installed on a concrete pillar 5 with a bolt nut 7. When the synthetic resin insulator 1 is used for many years in such a state, the surface of the synthetic resin insulator 1 is deteriorated (broken) by ultraviolet rays, and tracking 4 and erosion (pitting corrosion) due to high voltage occur on the surface,
It will no longer function as an insulator and become industrial waste. 12
Is an electric wire.

[0003]

The number of synthetic resin insulators used in transmission and distribution lines is very large. Therefore, when the synthetic resin insulators that have reached the end of their service life are replaced, a large amount of synthetic resin insulators become industrial wastes, and their disposal becomes a major problem.

[0004]

DISCLOSURE OF THE INVENTION The present invention provides a method for regenerating a synthetic resin insulator which solves the above problems, in which the surface of a used synthetic resin insulator is peeled off, and then the synthetic resin insulator is peeled off. It is characterized in that it is placed in a mold which is larger than the previous shape and has a substantially similar shape, and the mold is filled with a synthetic resin of the same material as the synthetic resin constituting the synthetic resin insulator.

[0005]

As described above, when the surface of the used synthetic resin insulator is peeled off, the constituent resin that has not deteriorated appears on the surface, and the adhesiveness with the synthetic resin that newly coats the surface is improved.
In addition, the mold is slightly larger than the original mold, so if you insert a synthetic resin insulator with the surface peeled off, a sufficient space will be created between the synthetic resin insulator and the mold to facilitate resin filling. Can be done. Since the surface of the synthetic resin insulator regenerated as described above is entirely new resin, it can be reused as an insulator having the same characteristics as the original synthetic resin insulator, saving resources. it can.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the embodiments shown in the drawings. 1 (a) and 1 (b) are explanatory views of an embodiment of a method for recycling a synthetic resin insulator according to the present invention.
The process is as follows. That is, 1) Since the surface 8 of the used synthetic resin insulator 1 is damaged at a depth of 1 to 2 mm, this thickness is peeled from the surface and a new surface 9 is exposed. The undamaged part may be thin and the damaged part may be deeply cut. The peeling method uses a mechanical method using a cutting tool, or an electrical or chemical method. 3a and 3b are metal fittings. 2) Next, the synthetic resin insulator 1 is put into molds 10a, 10b which are slightly larger than the original shape, and the synthetic resin insulator 1 is placed in a space 11 formed between the molds 10a, 10b and the synthetic resin insulator 1. A synthetic resin having the same quality as that of the synthetic resin portion 2 constituting the above is injected and hardened by heating or the like. In addition,
If the surface 9 of the synthetic resin insulator 1 is treated with a primer before injecting the synthetic resin, the adhesiveness with the newly injected resin is improved, and the surface 9 of the synthetic resin insulator 1 and the interface with the resin are improved. It is possible to prevent the occurrence of voids.

[0007]

As described above, according to the present invention, the surface of the used synthetic resin insulator is peeled off, and then the synthetic resin insulator is molded into a mold shape which is larger than the shape before the peeling and has a substantially similar shape. The mold is filled with a synthetic resin of the same material as the synthetic resin that constitutes the synthetic resin insulator, so that the used synthetic resin insulator can be regenerated and resources can be saved, It has an excellent effect that waste can be reduced.
