摘要：NOVELTY - The emulsification method of modified silicon dioxide involves dissolving ethanol and deionized water in a mass ratio of 8:2-19:1 in an aqueous ethanol solution, uniformly mixing, adding 5-50 wt.% surfactant to the mixture and then ultrasonically processing for 30 minutes, transferring the mixture to a high-speed emulsifying machine, adding silicon dioxide to the mixture and then carrying out surface modification treatment, emulsifying the mixture at 1000-5000 rpm for 1-5 hours and then centrifuging, washing the mixture and then drying, and crushing. USE - The method is useful for emulsification of modified silicon dioxide (claimed). ADVANTAGE - The method enables emulsification of modified silicon dioxide with excellent dispersibility and hydrophobic properties.
