NOVELTY - Preparing modified graphene insulation material involves mixing 4-9 pts. wt. expanded perlite, 2-7 pts. wt. polystyrene particles, 1-6 pts. wt. graphene, 3-8 pts. wt. ceramic fiber, 1-5 pts. wt. lecithin, and 3-12 pts. wt. glycerin to obtain a mixture. 10-20 pts. wt. Obtained mixture is heated at 60-80 degrees C, and 3-7 pts. wt. phenol resin and 2-6 pts. wt. diphenylsilanediol are added to obtained mixture under stirring condition to obtain another mixture. Latter mixture is refluxed 8-15 pts. wt. with 20-30 pts. wt. ethanol, and then filtered. Filtered product is dried. USE - Method for preparing modified graphene insulation material. ADVANTAGE - The modified graphene insulation material has flexural strength of more than 10 megapascals, absorption rate below 25%, and thermal conductivity of Watts per meter Kelvin. DETAILED DESCRIPTION - Preparing modified graphene insulation material involves mixing 4-9 pts. wt. expanded perlite, 2-7 pts. wt. polystyrene particles, 1-6 pts. wt. graphene, 3-8 pts. wt. ceramic fiber, 1-5 pts. wt. lecithin, and 3-12 pts. wt. glycerin to obtain a mixture. 10-20 pts. wt. Obtained mixture is heated at 60-80 degrees C, and 3-7 pts. wt. phenol resin and 2-6 pts. wt. diphenylsilanediol are added to obtained mixture under stirring condition to obtain another mixture. Latter mixture is refluxed 8-15 pts. wt. with 20-30 pts. wt. ethanol, and then filtered. Filtered product is dried. 7-20 pts. wt. Dried product is heated under vacuum condition. 1-5 pts. wt. Dibutyltin dilaurate and 3-6 pts. wt. n-butyl borane are added to obtained product under stirring condition, and thne heated at 60-90 degrees C. Obtained product is cooled to room temperature.
