A kind of preparation method of the anti-oxidant nuclear shell structure nano modification transformer oil containing sesame oil, comprises the following steps：
（1）First nano titanium oxide is compared 1 by solid-liquid weight:100-1:200 add ultrasonic disperse in absolute ethyl alcohol uniform, then It is slowly added to tetraethyl orthosilicate and VTES and stirs 0.5-1h and obtain mixed liquor, be finally slowly added dropwise quite In 1/20-1/10 mixeding liquid volume acetum and in 50-60 DEG C stir 2-4h, after cooling centrifugation and by the solid obtaining use Absolute ethanol washing for several times, obtains modified Nano grain, the mass fraction of described acetum is 4-6%；
（2）Sesame oil is processed and obtains refined sesame through alkali-refining deacidification, distillation, atlapulgite adsorption bleaching deodorization, 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 obtaining adds step（2）In the compound oil obtaining, ultrasonic disperse is uniform, Ran Houjia Enter 50-60 DEG C of stirring 0.5-1h of remaining raw material, after cooling, distillation, filtration are refined, obtain final product the anti-oxidant core shell structure containing sesame oil Nano modification transformer oil.
It is an advantage of the invention that：
The present invention utilizes tetraethyl orthosilicate and VTES hydrolytie polycondensation cladding nano-particle to form polysiloxanes Coated core-shell structure nanometer grain, has the stability of good dispersiveness, resistance to ag(e)ing and height, can stably be scattered in transformation In device oil, can effectively lift the insulation of transformer oil, radiating, ageing resistance, and be not easily susceptible to the shadow of extraneous service condition Ring and rotten, precipitation occurs, the performance of impact transformer oil；Meanwhile, using the refining of sesame oil and compounding with remaining raw material With synergistic effect so as to get transformer oil both there is excellent insulation, heat dispersion, stable in properties simultaneously, long service life, Also have the characteristics that antioxygenic property is good, practical.
