pouring a proper amount of quartz raw material mixture into a stirring kettle, pouring a proper amount of glass raw material mixture into another stirring kettle, stirring and mixing the two stirring kettles at the speed of 300 plus materials at 500rpm for 10-15min, transferring the quartz raw material mixture and the glass raw material mixture into the same stirring kettle, stirring and mixing at the speed of 500 plus materials at 600rpm for more than or equal to 30min, taking a proper amount of ceramic powder during stirring, adding the ceramic powder into the quartz raw material mixture and the glass raw material mixture once every 5min until the ceramic powder is completely added, and continuously stirring for more than or equal to 15min to obtain a raw material mixture;
step two:
taking a proper amount of resin, a medium-temperature curing agent and color paste, heating a stirring kettle to 50 ℃ in advance, pouring the resin, the medium-temperature curing agent and the color paste into the stirring kettle, stirring and mixing at the speed of 60-90rpm for 30-40min in total, and increasing the temperature of the stirring kettle from 50 ℃ to 75-85 ℃ within 10min before stirring to obtain a resin mixture;
step three:
adding the resin mixture obtained in the step two into the raw material mixture obtained in the step one, stirring and mixing at an initial speed of more than or equal to 90rpm by using a stirring kettle at the temperature of 75-85 ℃, then adding the coupling agent, increasing the stirring speed to 200-300rpm within 5min of the beginning of adding the coupling agent, and continuously stirring for more than or equal to 15min to obtain a mixture;
step four:
and (3) immediately injecting the mixture obtained in the step three into a prepared mould through a casting machine, closing and locking the mould, immediately conveying the mould into a vacuum hot press for vacuum high-pressure pressing for 15-20min, directly transferring the plate into a drying building after press forming, performing medium-temperature curing for 60-120min at the temperature of 90-110 ℃, finally taking out the plate, naturally cooling to room temperature, and polishing the plate to obtain the high-strength high-temperature-resistant quartz stone plate.
