description The invention relates to a hydroxyl fluorosilicone oil modified water-based organic silicon defoaming agent. Belongs to the technical field of defoaming agents. The hydroxyl fluorosilicone oil modified water-based organic silicon defoaming agent comprises the following components in parts by mass: 5-50 parts of polydimethylsiloxane, 0.1-5 parts of hydroxyl fluorosilicone oil, 0.1-5 parts of white carbon black, 1-30 parts of polyether modified silicone oil, 1-30 parts of an emulsifier, 0-5 parts of a thickening agent and 20-90 parts of deionized water, and the proportion of fluorine element in the total components except the deionized water is not less than 0.5 wt%. The hydroxyl fluorosilicone oil and the polyether modified organic silicon are subjected to in-situ chemical bonding, so that the stability of the defoaming agent is improved, and meanwhile, a good defoaming effect on a strong foaming system under the condition of extremely low dosage is realized. 本发明涉及一种羟基氟硅油改性的水性有机硅消泡剂；属于消泡剂技术领域。一种羟基氟硅油改性的水性有机硅消泡
