NOVELTY - Producing modified window glass material involves dissolving nano-magnesite, difluorobenzene derivative (I) and graphene in N,N-dimethylformamide under ultrasonic stirring to obtain modified mixed liquid. The obtained modified mixed liquid is mixed with polymethyl methacrylate, xylitol, aluminum hydroxide, silicon oxide, silver oxide, rare earth oxide and methyl vinyl phenyl oil to obtain mixture. The obtained mixture is melted, cooled, and granulated to obtain the desired material. USE - Method for producing modified window glass material for three dimensional printer (claimed). ADVANTAGE - The method enables to produce modified window glass material, which has excellent mechanical properties and wear resistance. DETAILED DESCRIPTION - Difluorobenzene derivative of formula (I). Mes=mesityl.
