The purpose of the present invention is to obtain a thin electrical insulating material with excellent heat resistance and insulation resistance, as well as a scale that has excellent thermal conductivity, easily dissipates heat, and is highly safe. This invention relates to an electrical insulating material r1 formed by forming a fired glaze layer on the surface and integrally forming a synthetic resin layer on the back surface, and a method for manufacturing the same.

The back surface is in close contact with the flat surface 2 or the molding surface 3.

At the same time as forming the Φ layer 5 (porous unglazed sheet), the glaze 4 on its surface melts and becomes extremely thin (less than 1 mm).
A fired layer 4 (vitreous coating) is formed on the glaze 2. Generally, the material is fired into a bisque firing state, cooled, coated with a glaze, and then fired, but in the present invention, the bisque firing process is omitted. The thin ceramic sheet a) is coated with epoxy resin on the unglazed surface of the exposed rear surface of the flat surface 2 or the molded surface 3, and is heated to harden it to form a synthetic resin layer 6 of approximately 2 cm. It is used as a product.

2) It can also be formed by bringing the same resin 6 into contact with each other (on the bisque fired surface) and curing the same resin 6. The wooden mold 7 is separated to form a transformer insulation case 10 as shown in FIG.

料を得ることができるものである。As described above, the present invention provides a fired glaze layer 4 on the surface of the unglazed thin layer 50.
Because it is a thin plate made of a thin ceramic sheet (a) formed by forming a synthetic resin layer 6 such as epoxy resin on the back side of the thin ceramic sheet (a), the dielectric strength and heat resistance of the ceramic sheet (a) is A highly safe electrical insulating material that has excellent conductivity, and the synthetic resin layer 6 can strongly adhere to the bisque bending on the back side of the thin ceramic sheet (a), significantly improving the mechanical strength of the thin ceramic sheet (a). can be easily obtained, and the surface of ceramic paper 1 is fully coated with glaze 4' in advance, and this is coated with glaze 13'εb.
W, it is possible to safely obtain an extremely thin (about 1 inch) thin ceramic sheet a, and also to strongly adhere the synthetic resin layer 6 to the unglazed rough surface on the back side to obtain a highly strong and extremely thin electrical insulating material. It is possible.
