step 5-2, discharging the sheet to obtain a half-raw half-cooked silica gel sheet, wherein the peripheral size of the half-raw half-cooked silica gel sheet is larger than that of the glass ceramic plate substrate and is matched with the inner cavity of the die;
and 5-3, stacking the half-cooked silica gel sheet and the microcrystalline glass plate substrate covered with the first graphene layer in the step 4 into the inner cavity of the die to form a stacked state that the lower layer is the half-cooked silica gel sheet, the middle layer is the microcrystalline glass plate substrate covered with the first graphene layer in the step 4 and the upper layer is the half-cooked silica gel sheet, pressing the top of the half-cooked silica gel sheet on the upper layer by using a pressure forming machine, and performing compression molding treatment to integrate the periphery of the half-cooked silica gel sheet on the upper layer with the periphery of the half-cooked silica gel sheet on the lower layer, thereby realizing full coating of the microcrystalline glass plate substrate covered with the first graphene layer in the step 4.
