▎ 摘　　要

NOVELTY - A modified graphene high-temperature resistant paint is prepared by taking graphene oxide and anhydrous pyridine, ultrasonically oscillating, dropping dichlorosilane, reacting, adding water, continuously stirring and reacting, filtering, washing solid to water, adding hydrazine hydrate, filtering, reacting, washing and vacuum drying to obtain surface grafted organic small molecules modified graphene powder, taking with silicone resin, adding dimethylbenzene, and ball milling. USE - Preparation of modified graphene high-temperature resistant paint (claimed). ADVANTAGE - The paint improves flexibility of silicon coating, adhesion, temperature and conductivity, and solves high-frequency power and lightning surge current high temperature and conductive and corrosion problems. DETAILED DESCRIPTION - A modified graphene high-temperature resistant paint is prepared by taking A g graphene oxide and B mL anhydrous pyridine, ultrasonically oscillating in ice water bath, dropping C mL dichlorosilane, reacting for 5-10 hours, adding D mL water, continuously stirring and reacting, filtering, washing solid to E L water, adding F g hydrazine hydrate, filtering, reacting in water bath at 90-95 degrees C for 1-1.5 hours, washing and vacuum drying to obtain surface grafted organic small molecules modified graphene powder, taking G modified graphene powder and H silicone resin, adding I dimethylbenzene, and ball milling for 2-5 hours. The ratio of A:B:C:D:E:F is 5:300-500:5-10:20-50:3-5:5-10. The ratio of G:H:I is 1:10-100:1-60.
