Abstract
The invention discloses a capacitor impregnant containing modified smectite powder and a preparation method thereof. The capacitor impregnant comprises the following raw materials by weight: 100-105 parts of mineral oil, 1 part to 3 parts of modified smectite powder, 2-5 parts of modified tree ash, 0.7-0.9 part of celestite, and 0.6-0.8 part of sodium lauryl sulfate. The capacitor impregnant adopts the mineral oil as a main material and is low in cost. Simultaneously, the modified vermiculite powder, the modified tree ash, the celestite and the sodium lauryl sulfate are added. Adsorption performance of moisture in the impregant is improved by modifying the smectite powder 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.
