▎ 摘  要

NOVELTY - A thermal insulation coating comprises 52-55 pts. wt. acrylic resin, 12-16 pts. wt. alkyd resin, 7-10 pts. wt. butyronitrile rubber, 22-25 pts. wt. modified graphene, 11-14 pts. wt. nano ceramic hollow particles, 15-18 pts. wt. talc powder, 2.5-3 pts. wt. silane couple agent KH-570, 1.2-1.5 pts. wt. coalescent, 1.6-1.9 pts. wt. dispersant, 1.4-1.7 pts. wt. defoamer, 1.5-1.8 pts. wt. anti-freezing agent, 0.8-1.1 pts. wt. antioxidant OD, and 64-67 pts. wt. solvent. USE - A thermal insulation coating. ADVANTAGE - The insulation coating has high impact resistance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparing the modified graphene, comprising: (A) placing 8-10 pts. wt. graphene, 13-15 pts. wt. of 1.1-1.4 mmol/L sodium nitrite solution and 18-20 pts. wt. n-hexanol in a first reactor, stirring at 115-120 revolutions/minute (rpm) for 1-1.5 hours, adding 1.5-2 pts. wt. of 96-98% sulfuric acid solution, heating to 62-65 degrees C, stirring at 100-120 rpm for 1.1-1.5 hours, cooling to 21-25 degrees C, centrifuging at 3600-3800 rpm, and drying to obtain material A; and (B) placing material A, 4-7 pts. wt. acetone, 5-9 pts. wt. vitamin C, and 5-7 pts. wt. nitroaniline in a second reactor, standing for 18-21 hours, and ultrasonically dispersing at 35-40 KHz and 1000-1200 W for 1.2-1.8 hour to obtain material B, filtering, and drying.
