Preparation method of layered ceramic curved plate

The invention discloses a preparation method of a layered ceramic curved plate, and the method comprises the following specific steps: 1) preparing a ceramic green sheet with the thickness of 0.1-5 mm; 2) cutting each layer of ceramic green body sheet according to the plane expansion diagram of the prepared layered ceramic curved plate, wherein the cut ceramic green body sheets ensure that a gap is formed between the edge and the inner wall of the mold during mold filling; 3) laminating the cut ceramic green sheets, cutting a V-shaped opening in an area where material wrinkles are easy to overlap during mould pressing, putting the ceramic green sheets into a steel mould, carrying out compression molding at 30-380 DEG C under the pressure of 50-500 kgf/cm , and carrying out heat preservation for 0.5-5 h. According to the method, the fluidity of the binder in a heating state is improved, drape overlapping is reduced by cutting the V-shaped opening, flowing of powder is promoted throughheating and pressing formi
