The mica plate manufactured in the prior art is prepared by using mica as a raw material in a hydropulper and using a high-pressure water gun to prepare 20-90 meshes of mica flakes, the mica flakes are made into mica paper (with the standard number: GB/T5019.4-2009, the thickness is generally only 0.07-0.1 mm) through a cylinder paper machine, the mica paper is soaked in an organic silicon resin binder and is dried in a dryer, the mica paper is cut into a certain length according to the requirement to obtain gummed paper, a plurality of gummed papers are stacked together according to the requirement of the thickness of the mica plate and are placed on a partition plate, the operation is repeated, when the stacking height reaches 10cm, another layer is taken, the plurality of layers are placed in a hot press for hot pressing, and the qualified mica plate for the electric heating equipment is obtained through pressure rise, temperature rise, constant temperature, constant pressure and gradual temperature. This manufacturing method has significant disadvantages, mainly:

2: the manufacturing process is complicated, and dozens of processes are usually carried out from the mica mineral aggregate to the mica plate.
3: in the pressing process, the number of layers is large, the layers are easy to separate, for example, an ultra-thick mica plate with the thickness of 20mm needs to be stacked by about 300 pieces of gummed paper, and the mica plate can be scrapped if any one sheet is defective.
4: the water consumption in the production of the papermaking mica paper is large, about 60 tons of water is consumed for each ton of mica paper, the water content of a finished mica paper product cannot exceed 1 percent, more than 99 percent of water is discharged, and about 6 percent of mica flakes with the particle size of less than-100 meshes in the water need to be precipitated for a long time to be discharged into a river, so that the floor area of each mica paper production line precipitation tank is about ten thousand square meters or more.
5, the energy utilization rate is low, when 500Kg of mica plate is heated to 250 ℃,5,500 Kg of electric heating plate is heated to 250 ℃, and the heat energy utilization rate is only 8.33 percent.
