Aluminum nitride nanoparticle transformer oil with good antifouling scale inhibition performances, and preparation method thereof

Abstract

The invention discloses an aluminum nitride nanoparticle transformer oil with good antifouling scale inhibition performances. The aluminum nitride nanoparticle transformer oil is characterized by being prepared from the following raw materials in parts by weight: 1000-1200 naphthenic base oil, 5-6 parts of aluminum nitride, 0.2-0.5 part of methyl benzotriazole, 0.2-0.5 part of sodium tripolyphosphate, 0.2-0.5 part of sodium nitilotriacetate, 0.3-0.5 part of lauryl phosphate, 0.2-0.5 part of tolyltriazole TTA, 0.2-0.5 part of polymaleic anhydride, 0.2-0.4 part of hydroquinone, and 0.5-1.0 part of auxiliaries. The aluminum nitride nanoparticle added in the transformer oil can enhance the heat conductivity, stability and insulating performance; the added auxiliaries enhance the oxidization resistance, moisture proofness and water resistance properties of the transformer oil; the added methyl benzotriazole and polymaleic anhydride increase the anticorrosion, antirust and scale inhibition properties of the transformer oil; nanoparticles are made by ball-milling absolute ethyl alcohol, and the used equipment is simple and easy to operate; according to the aluminum nitride nanoparticle transformer oil, the problems that the transformer oil is easy to oxide, age, corrode and moisten at high-temperature environment, poor in heat conducting property and the like can be effectively solved.

Description

technical field [0001] The invention relates to the chemical field, in particular to an aluminum nitride nanoparticle transformer oil with good antifouling and antiscaling properties and a preparation method thereof. Background technique [0002] We cannot live without a transformer in our daily life. It is an electrical appliance that uses the principle of electromagnetic induction to transfer electrical energy or transmit signals from one circuit to another. It is an important component for electrical energy transfer or signal transmission. It is often in an outdoor high-temperature environment. If the temperature is too high, it will be easily oxidized, damaged and have a short service life. Nowadays, people often use transformer oil to protect the transformer from excessive temperature and easy oxidation when it is working. Transformer oil, commonly known as square shed oil, is a light yellow transparent liquid that is a fractionation product of petroleum. Its main comp...

Problems solved by technology

[0003] Since transformer oil has a certain degree of water absorption, moisture has a great influence on transformer oil, which will reduce the breakdown capacity of oil products, and will accelerate the corrosion of copper and iron by organic acids, and the generated dirt will adhere to the coil and In the firmware, the channel is blocked, which seriously affects the heat dissipation, and causes local overheating of the coil in the transformer, which will cause major accidents
