The invention discloses an efficient
silicone defoaming agent, which mainly comprises a
silicone grease mixture, a synergistic agent, a polyether
silicone oil emulsifier, an assistant emulsifier, a
thickening agent,
preservative and water, wherein in an emulsifier
emulsion, the
silicone grease mixture and the polyether
silicone oil emulsifier account for 70-90 percent of the amount of active matters; the active matters account for 5-30 percent of the amount of the
emulsion; and water serves as another medium. In the efficient silicone defoaming agent, the foam inhibiting performance is enhanced by using the
silicone grease mixture, the defoaming performance and
dispersity are improved by using the polyether
silicone oil emulsifier, and the
silicone grease viscosity and compatibility are lowered and the emulsifying effect is improved by adding the synergistic agent. The efficient silicone defoaming agent has the characteristics of application to waterborne systems, high defoaming speed, good foam inhibiting effect, low using dosage, high chemical inertness, nontoxicity, capability of acting under severe conditions and low cost.
