▎ 摘　　要

NOVELTY - A wear-resistant oil-proof insulation coating comprises 40-44 pts. wt. silica powder, 26-29 pts. wt. acrylic resin, 18-21 pts. wt. nitrile rubber, 10-15 pts. wt. oxalic acid polyester, 22-25 pts. wt. modified graphene, 6-10 pts. wt. zinc oxide, 1.6-2 pts. wt. defoamer, 1.5-1.8 pts. wt. leveling agent, 1.1-1.4 pts. wt. dispersant, 1.6-1.8 pts. wt. coalescent, 1-1.3 pts. wt. 1-N-(4-methylpentan-2-yl)-4-N-phenylbenzene-1,4-diamine (antioxidant 4020), 3-6 pts. wt. drier, 1.2-1.5 pts. wt. fungicide, 1.5-1.8 pts. wt. anti-settling agent, and 0.6-1 pt. wt. rust inhibitor. USE - A wear-resistant oil-proof insulation coating (claimed). ADVANTAGE - Wear-resistant oil-proof insulation coating has high wear resistance and good oil-proof properties. DETAILED DESCRIPTION - A wear-resistant oil-proof insulation coating comprises 40-44 pts. wt. silica powder, 26-29 pts. wt. acrylic resin, 18-21 pts. wt. nitrile rubber, 10-15 pts. wt. oxalic acid polyester, 22-25 pts. wt. modified graphene, 6-10 pts. wt. zinc oxide, 1.6-2 pts. wt. defoamer, 1.5-1.8 pts. wt. leveling agent, 1.1-1.4 pts. wt. dispersant, 1.6-1.8 pts. wt. coalescent, 1-1.3 pts. wt. 1-N-(4-methylpentan-2-yl)-4-N-phenylbenzene-1,4-diamine (antioxidant 4020), 3-6 pts. wt. drier, 1.2-1.5 pts. wt. fungicide, 1.5-1.8 pts. wt. anti-settling agent, and 0.6-1 pt. wt. rust inhibitor in which modified graphene is prepared by adding 7-9 pts. wt. graphene, 11-13 pts. wt. of 1.2-1.5 mmol/L sodium nitrite solution, and 16-18 pts. wt. n-hexyl alcohol into 1st reaction vessel, stirring at 110-120 rpm for 1.2-1.6 hours, adding 1.2-1.5 wt.% of 96-98 wt.% sulfuric acid solution, heating at 63-66 degrees C, stirring at 110-130 rpm for 1-1.5 hours, cooling at 22-26 degrees C, centrifuging at 3500-3700 rpm, drying to obtain material A, adding material A, 3-6 pts. wt. acetone, 4-8 pts. wt. vitamin-C, and 6-9 pts. wt. nitroaniline into 2nd reaction vessel, standing for 20-22 hours, performing ultrasonic dispersion for 1.4-1.8 hours to obtain material B in which ultrasonic dispersion frequency is 36-40 kHz and ultrasonic dispersion power is 1100-1300 W, filtering, and drying.
