The invention discloses a preparation method for an antistatic synthetic glass film, which relates to the preparation method for material with antistatic function, and aims to solve the technical problem of lower antistatic performance of the conventional synthetic glass. The preparation method comprises the following steps: preparing POSS collosol by using silane coupling agent, alcohol, and acetic acid; preparing fullerene alcohol solid by using fullerene C60; adding POSS collosol and fullerene alcohol solid to polymethyl methacrylate prepolymer and mixing evenly to obtain filming solution; and coating filming solution on a substrate to obtain the antistatic synthetic glass film after solidification. According to the preparation method, the surface resistance of the antistatic synthetic glass film is 1011-1013 omega; the technique is simple; the operation is easy and simple; the preparation condition is mild; the repetition rate is high; and the antistatic synthetic glass film is permanent antistatic material, and can be used in the precision electronic and electrical field.
