▎ 摘　　要

NOVELTY - An anticorrosion primer comprises component (A) and component (B), where the component (A) comprises 8-15 wt.% epoxy resin, 5-10 wt.% novolac epoxy resin, 0.5-1 wt.% bisaminoalkoxysilane, 0.5-1 wt.% graphene, 0.25-0.5 wt.% carbon nanotube, 65-80 wt.% zinc base, 0.1-0.5 wt.% fumed silica, 0.5-1 wt.% additive and the rest is solvent, and the component (B) comprises 95-99 wt.% phenalkamide curing agent and 1-5 wt.% 2,4,6-tris(dimethylaminomethyl) phenol. USE - The anticorrosion primer is used in ductile iron castings, which is used in wind power generators. ADVANTAGE - The anticorrosion primer has excellent heat resistance and anti-corrosion performance when compared with the existing technology, and provides coating with excellent crack resistance and impact resistance. The zinc powder base material with new type of graphene and carbon nanotubes greatly reduces the dosage of the zinc powder material. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a preparation method of the anticorrosion primer comprising (S1) measuring a part of xylene and n-butanol solvent, mixing well, dripping water, dispersing and emulsifying to obtain a mixed solution, (S2) adding graphene and carbon nanotubes to the mixed solution obtained in step (S1) and dispersing evenly, (S3) heating the solution treated in step (S2) at 60-70℃ and adding bisaminoalkoxysilane under stirring, (S4) adding the novolac epoxy resin to the solution treated in step (S3) and raising the temperature at 60-90℃ to react, (S5) adding the epoxy resin to the solution treated in step (S4), stirring evenly and adding water remover, (S6) adding additives and fumed silica to the solution treated in step (S5), dispersing evenly and raising the temperature at 45-50℃ and (S7) adding the zinc base material to the solution treated in step (S6) and dispersing uniformly to obtain the component (A), preparing the component (B) by weighing the phenalkamide curing agent and 2,4,6-tris(dimethylaminomethyl)phenol in proportion and mixing uniformly to obtain the component (B).
