Summary:The invention relates to the technical field of chemical materials, in particular to an emulsion type concrete defoaming agent and a preparation method thereof.The emulsion type concrete defoaming agent is prepared from, by mass, 8.5%-23% of silicon paste, 3%-8% of alkynol, 1%-10% of an emulsifying component, 0.1%-4% of a thickening component, 0.1%-4% of an anti-corrosion component and the balance water. According to the emulsion type concrete defoaming agent provided by the embodiment of the invention, the modified polysiloxane, the polyether modified silicone oil and the alkynol are compounded to serve as main defoaming and foam inhibition components, and the surface tension is effectively reduced and the dispersity in a concrete system is improved by grafting polyether chain segments while fluorine is introduced into the defoaming agent; and alkynol is introduced as a main foam inhibition component and is suitable for a concrete system to maintain beneficial small bubbles, the foam film rupture is accelera
