The invention provides an emulsion type fluorine-containing organosilicone defoaming agent for an oil and aqueous two-phase system and a preparation method thereof, wherein the defoaming agent includes the following components: polyether and acrylate co-modified fluorine-containing silicone oil, silicon paste, silicon resin, an emulsifier, a thickener and water. The defoaming and foam inhibition performance of an aqueous phase and an oil phase are improved by introducing the silicon resin and a fluorine-containing group into the system. When the defoaming agent is used in the aqueous phase system, solubilization of the silicone oil in the aqueous-phase system can be effectively inhibited, the defoaming and foam inhibition performance is improved, and the high-temperature strong alkaline resistance can be improved. When the defoaming agent is used in the oil phase system, the oil resistance of dimethicone can be significantly increased, and the defoaming agent becomes a highly efficientdefoaming agent in raw oil, lubricating oil, organic solvents and other oil-phase systems.
