NOVELTY - Activated calcium carbonate comprises at least one of calcium carbonate, graphene, ethylene propylene diene monomer, triethyl citrate, liquid epoxy resin, phenyl glycidyl ether, styrene oxide and butyl glycidyl ether, at least one of dicyandiamide, ethyl amine trifluoride and 2-ethyl-4-methylimidazole, coupling agent and activating agent. USE - Used as activated calcium carbonate. ADVANTAGE - The activated calcium carbonate: can solves the problem that the existing activated calcium carbonate has poor effects in terms of reinforcement, high temperature resistance and low temperature resistance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the activated calcium carbonate comprising (1) adding calcium carbonate to high-speed mixer, stirring and measuring the temperature in the mixer, when the temperature rises to 65oC, adding at least one of graphene, ethylene propylene diene monomer, triethyl citrate, liquid epoxy resin, phenyl glycidyl ether, styrene oxide and butyl glycidyl ether, and at least one of dicyandiamide, ethyl amine trifluoride and 2-ethyl-4-methylimidazole, continuously stirring and heating; (2) when the temperature in the mixer rises to 75oC, adding the coupling agent, and continuously heating to 100oC; (3) when the temperature in the mixer drops to 60oC, adding activating agent, and keeping the temperature for 2 hours; and (4) drying and crushing the mixture in the mixer to obtain activated calcium carbonate.
