Abstract
A compound impregnating varnish and a preparation method thereof are disclosed. The varnish is characterized by being composed of following components in parts by weight: 34 to 36 parts of E-12 epoxy resin, 10 to 12 parts of terpolycyantoamino-formaldehyde resin, 4 to 6 parts of dimethyl dichlorosilane, 6 to 8 parts of styrene, 2 to 3 parts of butadiene, 3 to 4 parts of neopentylene glycol, 6 to 7 parts of bis-dodecanol ester, 1 to 2 parts of tert butyl peroxypivalate, 3 to 4 parts of acrylic acid-2-hydroxypropyl, 1 to 2 parts of titanate coupling agent TMC-TTS, 34 to 36 parts of xylene, 12 to 14 parts of ethyl acetate, and 4 to 5 parts of film forming agent. The preparation method adopts epoxy resin compound and induces titanate coupling agent TMC-TTS, so the compactness of the varnish membrane is increased. The compound impregnating varnish has the advantages of high-temperature and high-dampness resistance, good electric insulation property and high mechanic strength, the heat conductivity of the varnish is improved, so the varnish can work at the temperature of 180 DEG C for a long period and at the temperature of 220 for a short period, and the design requirements are satisfied.
