Abstract
The invention discloses a capacitor impregnant containing modified bentonite and a preparation method thereof. The capacitor impregnant comprises the following raw materials by weight: 110-115 parts of soybean oil, 2-4 parts of modified bentonite, 1 part to 3 parts of modified tree ash, 1.3-1.8 parts of magnesium oxide, 2-4 parts of hydrated magnesium silicate ultrafine powder and 1.5-2.5 parts of fatty alcohol-polyoxyethylene ether. The capacitor impregnant adopts the soybean oil as a main material and is low in cost. Simultaneously, the modified bentonite, the modified tree ash, the magnesium oxide, the hydrated magnesium silicate ultrafine powder and the fatty alcohol-polyoxyethylene ether are added. Adsorption performance of moisture in the impregant is improved by modifying the bentonite and the tree ash. The capacitor impregant has good flowability and heat resistance, is free of corrosion and impurity, and is capable of effectively improving electric performance of a capacitor and prolonging service life of the capacitor.
