The invention belongs to the technical field of wet-mixed mortar, and particularly discloses a preparation method of a special admixture mother liquor for limestone-based wet-mixed mortar. The method comprises the following steps: stirring and dissolving 0.05-0.15 part of a composite initiating component M, 5-8 parts of a monomer A, 0.05-0.1 part of a monomer B, 0.5-1.5 parts of a monomer C and 0.5-2 parts of a monomer D in a reaction kettle; adding 3-5.5 parts of a monomer D and 0.01-0.05 part of an aqueous solution of an initiating component N into the reaction kettle, continuously stirring and reacting for 0.5-1 hour, and respectively dropwise adding 2-4 parts of a curing component and 3-5 parts of a calcium source aqueous solution; and adding 2-5 parts of an air entraining component, 0.02-0.07 part of an air stabilizing component, 0.1-0.5 part of a plastic stabilizing component and 3-6 parts of a coagulation adjusting component into the mixture obtained in the step 2, and uniformly stirring to obtain milk
