▎ 摘　　要

NOVELTY - Preparing glass material involves dissolving nano-bentonite, benzamide derivative (I) and a complex structure of graphene in N, N-dimethylformamide in the presence of ultraviolet light, and stirred to obtain a modified ultrasonic liquid. The obtained liquid is mixed with polymethyl methacrylate, pentaerythritol, aluminum hydroxide, titanium oxide, silver oxide, rare earth oxide, diaminodiphenylmethane and modified liquid mixture, then melting, cooling and granulating to obtain final product. USE - Method for preparing glass material for three-dimensional printing (claimed). ADVANTAGE - The method enables to prepare glass material which has excellent mechanical performance and high temperature resistance performance. DETAILED DESCRIPTION - Preparing glass material involves dissolving nano-bentonite, benzamide derivative of formula (I) and a complex structure of graphene in N, N-dimethylformamide in the presence of ultraviolet light, and stirred to obtain a modified ultrasonic liquid.
