Abstract

The invention relates to a preparation method of antioxidant plant insulating oil and belongs to the technical field of insulating oil. The antioxidant plant insulating oil is prepared by adding beta-cyclodextrin embedded sage essential oil microcapsules, sage essential oil contains diterpenoid compounds such as carnosic acid and carnosol which can effectively remove oxygen ions, protect the plantinsulating oil from damage and inhibit the peroxidation effect of lipid at the same time, and an aqueous or alcohol extract of plant sage leaves is an effective antioxidant and an effective free radical scavenger. The antioxidant plant insulating oil is prepared by adding lipophilic silica nanoparticles, and the silica nanoparticles can absorb active oxygen generated during aging of the plant insulating oil, effectively inhibit the oxidation process of plant insulating oil ester molecules, improve the oxidation resistance of the plant insulating oil and the ability to adsorb the active oxygenand effectively adsorb the beta-cyclodextrin embedded sage essential oil microcapsules to avoid the phenomenon of agglomeration of the microcapsules.

Description

Technical field [0001] The invention relates to a preparation method of antioxidant vegetable insulating oil, which belongs to the technical field of insulating oil. Background technique [0002] Vegetable oil is produced from natural oil crops through pressing and refining processes. It has a wide range of sources and is almost completely degradable. It is renewable and has great potential in the development of oil sources. Because of its environmental friendliness and renewability, vegetable oil has regained the attention of many scientific researchers, and it may become a green substitute for mineral oil. In general, plant-based insulating oil has the following advantages: [0003] (1) Good electrical performance. After edible vegetable oil is refined, its electrical performance indicators are equal to or better than mineral insulating oil. The power frequency breakdown voltage, relative dielectric constant and other properties reach or exceed the level of mineral insulating ...
