Novel mica composite ceramic fiber cotton fireproof heat insulation blanket

The utility model discloses a novel mica composite ceramic fiber cotton fireproof heat insulation blanket, which comprises a composite sheet body formed by stacking a first mica sheet, ceramic fiber cotton and a second mica sheet in sequence, and the upper surface of the composite sheet body is provided with a plurality of through positioning holes. A positioning hole is formed in the surface of the composite sheet body, first high-temperature-resistant adhesive tapes are adhered to the edges of the side face, the upper end face and the lower end face of the composite sheet body for edge sealing, and second high-temperature-resistant adhesive tapes are adhered to the inner wall of the positioning hole and orifices in the two ends of the positioning hole. The side face of the composite sheet-shaped body is sealed by the first high-temperature-resistant adhesive tape, so that displacement or layering during overall use is effectively prevented, effective compounding of the mica sheet and the ceramic fiber cotto
