NOVELTY - A dry powder reflection heat insulation coating comprises polymer-modified graphene oxide. The polymer-modified graphene oxide is prepared by adding 10 mmol of 3,3'-diaminobenzidine, 11 mmol 1,4,5,8-naphthalene tetracarboxylic anhydride, 22 mmol benzoic acid, 3 mL isoquinoline, and 40 mL m-cresol to flask, protecting by nitrogen gas, magnetically stirring for 2 hours, heating to 85 degrees C for 6 hours, reacting at 190 degrees C for 21 hours, cooling to 70 degrees C, quickly pouring in 150 mL methanol, repeatedly washing with methanol, filtering, collecting polymer, and vacuum drying at 160 degrees C for 20 hours. USE - Dry powder reflection heat insulation coating (claimed). ADVANTAGE - The coating has low heat conduction coefficient, high reflectivity, high wear resistance, high flame resistance, and high weather resistance.
