Abstract
A reinforced mica paper includes reinforced mica paper as a base material obtained by mechanically pulverizing muscovite mica or phlogopite mica to form scaly mica and making the scaly mica into paper, a reinforcing material layer formed on at least one surface of the base material, and an adhesive coated on and impregnated in the reinforcing material layer and consisting of a mixture obtained by mixing arbitrary amounts of a silicone resin, aluminum hydroxide, aluminum silicate, potassium titanate, and a soft mica powder. A method of manufacturing the reinforced mica paper is also disclosed.
Claims8
A reinforced mica paper comprising:
- a base made of reinforced mica obtained by mechanically pulverizing muscovite mica or phlogopite mica to form scaly mica and making said scaly mica into paper;
- a reinforcing material layer formed on at least one surface of said base;
- and
- an adhesive coated on and impregnated in said reinforcing material layer and consisting of a mixture obtained by mixing 100 parts by weight of a silicone resin, 50 200 parts by weight of aluminum hydroxide, 50 to 200 parts by weight of aluminum silicate, 2 to 20 parts by weight of potassium titanate, and 2 to 20 parts by weight of a phlogopite mica powder.
A method of manufacturing a reinforced mica paper, comprising the steps of:
- mechanically pulverizing muscovite mica or phlogopite mica to form scaly mica and making said scaly mica into paper, thereby forming a base made of reinforced mica;
- forming a reinforcing material layer on at least one surface of said base material;
- and
- coating and impregnating an adhesive consisting of a mixture obtained by mixing 100 parts by weight of a silicone resin, 50 to 200 parts by weight of aluminum hydroxide, 50 to 200 parts by weight of aluminum silicate, 2 to 20 parts by weight of potassium titanate, and 2 to 20 parts by weight of a phlogopite mica powder in said reinforcing material layer.
