A kind of preparation method of antioxidation nano modification transformer oil, comprises the following steps：
（1）Nano-silicon dioxide hollow sphere is compared 1 by solid-liquid weight first:100-1:200 add ultrasonic disperse in dehydrated alcohol equal Even, it is then slowly added into tetraethyl orthosilicate and VTES and stirs 0.5-1h and obtains mixed liquor, last slow Deca equivalent to 1/20-1/10 mixeding liquid volumes boric acid solution and in 50-60 DEG C stir 2-4h, be centrifuged after cooling and will obtain Solid with absolute ethanol washing for several times, obtain modified Nano grain, the mass fraction of the boric acid solution is 4-6%；
（2）Oleum Ricini is processed through alkali-refining deacidification, distillation, the deodorize of active hargil adsorption bleaching and obtains refined caster oil, then Add and 80-90 DEG C of stirring 1-2h, be eventually adding 50-60 DEG C of mixing 0.5-1h of naphthenic base oils, after cooling, obtain compound oil；
（3）By step（1）The modified Nano grain for obtaining adds step（2）In the compound oil for obtaining, ultrasonic disperse is uniform, 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 antioxidation 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, the insulation of transformer oil, radiating, ageing resistance can be effectively lifted, and is 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 Ricini and with remaining raw material With potentiation, so as to get transformer oil there is excellent insulation, heat dispersion both, while stable in properties, long service life, The characteristics of also having antioxygenic property good, practical.
Specific embodiment
