Abstract
The invention discloses aluminum nitride-boron nitride nano particle transformer oil with high thermal resistance and superconductivity. The transformer oil is characterized by being prepared from the following raw materials in parts by weight: 1000-1200 parts of epoxy base oil, 2-3 parts of aluminum nitride, 0.2-0.5 part of 2-ethylhexyl nitrate, 0.2-0.5 part of sodium nitrite, 0.2-0.5 part of aluminum silicate, 0.3-0.5 part of borax, 0.3-0.5 part of barium titanate, 2-3 parts of boron nitride, 0.3-0.6 part of zinc stearate and 0.5-0.8 part of auxiliaries. Due to addition of the aluminum nitride-boron nitride nano particles in the transformer oil, the thermal conductivity, stability and insulativity of the transformer oil are improved; due to addition of zinc stearate, the thermal stability of the transformer oil is improved; due to addition of the auxiliaries, the oxidation resistance, moisture resistance and water resistance of the transformer oil are improved; an absolute ethyl alcohol ball-milling method is adopted to prepare the nano particles, the method is simple, and the equipment is easy to operate; the transformer oil disclosed by the invention is excellent in thermal conductivity, thermal resistance, moisture resistance, oxidation resistance and stability, so that the service life of the transformer oil is prolonged, and potential safety hazards are reduced.
Description
technical field [0001] The invention relates to the field of chemistry, in particular to an aluminum nitride-boron nitride nanoparticle transformer oil with strong heat resistance and superconductivity and a preparation method thereof. Background technique [0002] Transformer oil, commonly known as square shed oil, is a light yellow transparent liquid that is a fractionation product of petroleum. Its main components are compounds such as alkanes, naphthenic saturated hydrocarbons, and aromatic unsaturated hydrocarbons. The relative density is 0.895. Freezing point <-45 ℃. Transformer oil refers to a type of insulating oil used for insulation, arc extinguishing and cooling in oil-filled equipment such as transformers, reactors, transformers, bushings, and oil switches. In electrical equipment, transformer oil can isolate live parts of different potentials and increase the insulation strength so that it will not form a short circuit and will not be broken down. This is t...
