Abstract

The invention discloses aluminium nitride nanoparticle transformer oil with high oxidation resistance and high corrosion resistance. The aluminium nitride nanoparticle transformer oil is characterized by being prepared from the following raw materials in parts by weight: 1000-1200 parts of naphthenic base oil, 3-5 parts of aluminium nitride, 0.2-0.5 part of 2,6-Di-tert-butyl-p-Ethyl-phenol, 0.2-0.5 part of 2-mercapto benzothiazole, 0.2-0.5 part of sodium benzoate, 0.2-0.5 part of diboride vanadium, 0.3-0.5 part of benzotriazole, 0.4-0.8 part of molybdenum disulfide, 0.4-0.6 part of zirconium oxide and 0.5-1.0 part of an additive. According to the invention, the added aluminium nitride nanoparticles enhance the thermal conduction, stability and insulativity; the added additive enhances the oxidation resistance, the moisture resistance and the waterproofness of the transformer oil; the added benzotriazole and zirconium oxide improve the corrosion resistivity of the transformer oil; the nanoparticles are manufactured through the anhydrous ethanol ball milling method, the equipment in use is simple and easy to operate; the problem that the conventional transformer oil is poor in oxidation resistance and corrosion resistance is effectively solved, and the thermal conduction, the stability, the insulativity and the moisture resistance are enhanced.

Description

Technical field [0001] The invention relates to the field of chemistry, in particular to an aluminum nitride nanoparticle transformer oil with strong oxidation resistance and corrosion resistance and a preparation method thereof. Background technique [0002] Transformer oil, commonly known as cubicle oil, is a light yellow transparent liquid. It is a fractionated product of petroleum. Its main components are alkanes, naphthenic saturated hydrocarbons, aromatic unsaturated hydrocarbons and other compounds, with a relative density of 0.895. Freezing point <-45℃. Transformer oil has the function of protecting insulating materials and reducing the temperature of transformer cores and other components due to its high insulation strength and large specific heat. Because the oil-immersed switch cuts off the electrical load, its fixed contacts and sliding A very high arc is generated between the contacts. Because the transformer oil has good thermal conductivity, and can separate a ...

Problems solved by technology

Oil products will inevitably come into contact with oxygen during long-term use, which will cause the oil to age and form acidic substances or sludge. However, acidic substances will corrode copper, iron and other metal materials used in the equipment to form metal salts, which will accelerate the aging of oil products. , the generated sludge sticks to the coil and insulating parts, accelerates the aging of insulating materials and affects heat dissipation
