The invention discloses a method for preparing nano SiO2 through a microemulsion online monitoring process. The method includes: preparing nano SiO2 through the microemulsion process; adopting an online granularity analysis system to continuously monitor change of particle diameter of SiO2 particles; analyzing changing tendency of characteristics of the nano SiO2 particles within 24h, like granularity and number to regulate size of microemulsion balls and hydration particle diameter of nano SiO2. SiO2 prepared by the method is controllable in particle diameter, narrow in distribution and highin dispersity, and average particle diameter of SiO2 is within a range of 50-400nm.
