Example Embodiment
[0021] Example 1
[0022] Mix the polysiloxane resin powder with a particle size of 6um and the nanometer lithium phosphate powder with a particle size of 8nm and diatomaceous earth in the formula thoroughly through a high-speed mixer, and then hot press into a 100μm thick sheet, and put them together Into a high temperature furnace equipped with an exhaust port at a temperature of 1200℃, process for 150 minutes under the condition of a negative pressure of 0.096Mpa. The metal pipe connected at the end of the exhaust port is directly connected to a cooling device equipped with water. The top outlet is connected with the air inlet of the vacuum pump, and the air outlet is directly vented; then the processed polysiloxane resin and lithium phosphate flakes are transported to the room temperature air chamber without water vapor and cooled to room temperature through the conveyor belt; The processed substrate sheet has a porosity of 78% and a pore diameter of 5um; the hydrogen, oxygen...
