NOVELTY - Building material comprises 16-20 pts. wt. graphene oxide, 120-130 pts. wt. styrene, 2-3 pts. wt. ricinoleic acid, 0.4-1 pts. wt. glycerol tristearate, 4-6 pts. wt. tert-butyl-p-diphenol, 4-5 pts. wt. ammonium sulfate, 6-10 pts. wt. organic filler, 1-2 pts. wt. oleic acid diethanolamide and 0.8-1 pts. wt. silane coupling agent kh550. USE - Used as building material. ADVANTAGE - The material has low cost, saves energy, and improves compatibility between the polymer filler. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing building material comprising (a) taking silane coupling agent kh550, adding into 10-14 times of anhydrous ethanol, stirring uniformly, adding graphene oxide, heating to 60-65 degrees C and preserving for 1-2 hours, distilling to remove ethanol, and then drying at normal temperature to obtain amino graphene oxide, (b) taking organic filler and glycerol tristearate, adding into pentaerythritol, and then ultrasonicating for 3-10 minutes to obtain dispersion, (c) taking oleic acid diethanolamide, adding into 25-30 times of deionized water, and then stirring uniformly to obtain alcohol amide dispersion, (d) taking ammonium persulfate, adding into 17-20 times of deionized water, and then stirring uniformly, (e) taking styrene, ricinoleic acid, adding into alcohol amide dispersion, stirring uniformly, adding into a reaction kettle, passing nitrogen gas, adjusting temperature of the reaction kettle to 65-70 degrees C, dropping ammonium persulfate solution, preserving temperature and stirring for 3-4 hours to obtain acid doped polystyrene solution, and (f) taking graphene oxide, adding into acid-doped polystyrene solution, preserving temperature and stirring at 60-65 degrees C for 2-3 hours, mixing with alcohol dispersion, ultrasonicating for 10-15 minutes, filtering, washing the precipitate, vacuum drying at 50-60 degrees C for 1-2 hours, and then cooling to normal temperature to obtain final product.
