Preparation method of high-temperature-resistant ceramic base polymer

The invention provides a preparation method of a high-temperature-resistant ceramic base polymer. The preparation method comprises the following steps: (1) performing ultrasonic cleaning on recycled waste ceramic; putting the cleaned ceramic raw material into a ball mill; performing ball milling on the ceramic raw material, so as to enable the average particle size of the ceramic raw material to be lowered to 10-50 micron; (2) adding an excitant solution into the levigated ceramic; adjusting the liquid/solid ratio of the excitant solution to the ceramic powder to be (0.3-0.5): 1; fully stirring the mixture; pouring the reagent into an alkaline-resistant mold; placing the mold on an electric vibrating table; vibrating the mold for 3-10 min; (3) sealing the mold after the mold is vibrated; performing demolding after the mold is placed at the room temperature or in a maintenance box at 20-60 DEG C for 24 hours; (4) continuing to maintain the demolded sample at the room temperature to 60 DEG C for a scheduled age
