スの分散性か悪くなり好ましくない。In the present invention, the above-mentioned insulating varnish contains a specific amount of a specific glass fiber. Specific glass fibers include fibers with an average length of 100 to 500 m. That is, if the average length of the fibers is shorter than 100 m, the thermal shock resistance will decrease, and if it exceeds 500 It m, the dispersibility of the insulating varnish will deteriorate, which is not preferred.

It is applied at a ratio of 5 to 40 parts by weight to 00 parts by weight. That is, if it is less than 5 parts by weight, the effect will not be as good as 1', and if it is more than 40 parts by weight, the dispersibility of the insulating varnish will deteriorate, which is not preferable.

くなり好ましくない。Furthermore, the insulating material 1'1 of the present invention may contain a specific fine silica powder. If this powder is too large, the dixo effect will be lost. For this purpose, a silica powder of 200 to 300 parts by weight is applied, and is used in an amount of 4 to 10 parts by weight per 100 parts by weight of the non-volatile content of the insulating varnish. If the amount is less than 4 parts by weight, the effect will not be sufficient, and if it is more than 10 parts by weight, the insulation properties and thermal shock resistance of the insulating material 111 will deteriorate, which is not preferable.
更にまた、本発明の絶縁塗料には顔料が含イｔされる。Furthermore, the insulating paint of the present invention contains a pigment.

The pigment is applied in an amount of 3 to 10 parts by weight and 411 parts by weight based on 100 parts by weight of the nonvolatile content of the insulating coating described in -1-. That is, if it is less than 3 parts by weight, the effect will be small, and if it is less than 10 parts by weight.
If the amount is more than 1 part by 6, the thermal shock resistance of the insulating paint will deteriorate, which is not preferable.

。In the present invention, the glass fibers improve the mechanical strength and thermal shock resistance of the insulating paint, and the fine silica powder prevents the glass fibers from settling and improves the edge coverage of the insulating paint. It is believed that it is effective in improving sex. It is also believed that the pigment acts as a dispersant, and has the effect of preventing the fine silica powder from agglomerating.
