A kind of preparation method of the modified transformer oil of nuclear shell structure nano of salt spray resistance containing Oleum Camelliae, comprises the following steps：
（1）First nano titanium oxide is compared into 1 by solid-liquid weight:100-1:200 add ultrasonic disperse in dehydrated alcohol uniform, then It is slowly added to tetraethyl orthosilicate and VTES and stirs 0.5-1h to obtain mixed liquor, is finally slowly added dropwise quite In 1/20-1/10 mixeding liquid volumes acetum and in 50-60 DEG C stir 2-4h, after cooling centrifugation and by the solid for obtaining use Absolute ethanol washing for several times, obtains modified Nano grain, and the mass fraction of the acetum is 4-6%；
（2）Oleum Camelliae is processed through alkali-refining deacidification, distillation, the deodorize of active hargil adsorption bleaching and obtains refined Oleum Camelliae, then 80-90 DEG C of stirring 1-2h of Semen Ricini base di-n-octyl sebacate and dinonyl naphthalene sulfonate barium is added, naphthenic base oils 50- is eventually adding 60 DEG C of mixing 0.5-1h, obtain compound oil after cooling；
（3）By step（1）The modified Nano grain for obtaining adds step（2）Ultrasonic disperse is uniform in the compound oil for obtaining, Ran Houjia Enter 50-60 DEG C of stirring 0.5-1h of remaining raw material, distillation, filtration are refined after cooling, obtain final product nucleocapsid structure of the salt spray resistance containing Oleum Camelliae Nano modification transformer oil.
It is an advantage of the invention that：
The present invention forms polysiloxanes using tetraethyl orthosilicate and VTES hydrolytie polycondensation cladding nanoparticle Coated core-shell structure nanometer grain, the stability with good dispersibility, resistance to ag(e)ing and height can stably be scattered in transformation In device oil, insulation, radiating, the ageing resistance of transformer oil can be effectively lifted, and be not easily susceptible to the shadow of extraneous service condition Ring and rotten, precipitation occurs, affect the performance of transformer oil；Meanwhile, the compounding using the refine of Oleum Camelliae and with remaining raw material With potentiation, so as to get transformer oil both there is excellent insulation, heat dispersion, while stable in properties, long service life, The characteristics of also having salt spray resistance good, good environmental adaptability is practical.
