摘要：
The defoaming agent of silicone oil emulsion containing hydrophobic SiO2 particles was prepared. The effect of different diameters of SiO2 particles and amount of SiO2 particles in the emulsion on the defoaming performance was studied, and the mechanism of defoaming was analyzed. The experimental results showed that when the amount of hydrophobic SiO2 particles in the emulsion was 1%, the emulsion had good defoaming performance; The emulsion containing nanometer sized SiO2 particles showed better defoaming performance than that of the emulsion containing micrometer sized SiO2 particles.
