The invention discloses a preparation method of aerogel glass. The preparation method comprises the following steps: weighing raw materials including aerogel powder and a methyl methacrylate matrix according to weight, adding the prepared methyl methacrylate matrix into a reaction kettle, stirring to convert the methyl methacrylate matrix into a prepolymer, so that the conversion rate of the prepolymer reaches 25-35%, adding the weighed aerogel powder into the prepolymer with the conversion rate of 25-35%, continuously stirring and uniformly mixing to form a mixed prepolymer, enabling the conversion rate of the mixed prepolymer to reach 50%, filtering the mixed prepolymer, then adding the filtered mixed prepolymer into a mold, and carrying out vibration exhausting, promoting final polymerization until the mixed prepolymer in the mold is in a gel state, and continuously heating and keeping the temperature, so that the mixed prepolymer in the gel state forms formed aerogel organic glass.According to the prepara
