The invention provides a compound, an air-entraining copolymer and a preparation method thereof, and application of the air-entraining copolymer as a rheological modifier for concrete. The preparationmethod for the air-entraining copolymer comprises a step of subjecting a monomer A, a monomer B and a monomer C of specific structures and in a molar ratio of 1: (0.5-2): (0.01-0.04) to free radicalcopolymerization, wherein the prepared air-entraining copolymer has a number-average molecular weight of 2, 000, 000 to 4, 000, 000, and the monomer C is a surface active molecule containing a hydrophilic phosphate group and a hydrophobic C8-18 alkyl chain. The monomer C is used as an air-entraining component and introduced into the copolymer, so the prepared copolymer has mild air entraining performance, can introduce stable, tiny and uniform bubbles into newly-mixed concrete, improves the resistance of the concrete to segregation and weeping, enhances the flowability of the concrete and makes the concrete highly workable.
