Method for detecting curing degree of resin in casting sand mold plate by using differential scanning calorimeter

The invention relates to the technical field of resin performance detection and further discloses a method for detecting a curing degree of the resin in a casting sand mold plate through a differential scanning calorimeter. The method specifically comprises steps of 1, weighing 10g of rock wool board samples into three groups for later use, closing a door plate of a muffle furnace, turning on a switch of the muffle furnace, heating the muffle furnace to 550 DEG C, opening the door plate of the muffle furnace, quickly putting the three groups of rock wool board samples into the muffle furnace for firing, and keeping the muffle furnace at a constant temperature of 550 DEG C for two hours, and step 2, after carrying out constant-temperature firing of the three groups of rock wool board samples for two hours by using the muffle furnace, turning off the switch of the muffle furnace, opening the door plate of the muffle furnace, taking out the three groups of rock wool board samples, and placing the three groups of
