Processing technology of special-shaped mica insulation product

The invention relates to the technical field of mica insulation products, in particular to a processing technology of a special-shaped mica insulation product. A processing technology of a special-shaped mica insulation product comprises the following steps that S1, white mica, biotite and fluorophlogopite are evenly mixed and then put into a siloxane coupling agent aqueous solution, ultrasonic treatment is conducted, and a modified mica mixture is obtained; s2, the modified mica mixture and a toughening composition are evenly mixed and then stirred and mixed with organic silicon resin, mica slurry is obtained, and the toughening composition is prepared from modified alkali-free glass fibers, silicon carbide whiskers and zinc oxide whiskers; and S3, injecting the mica slurry into a mold, and obtaining the special-shaped mica insulation product by adopting a four-step hot press molding method. The prepared special-shaped mica insulation product is good in bending resistance and high in heat resistance, it is g
