Abstract
An alkyd impregnating varnish and a preparation method thereof are disclosed. The varnish is characterized by being composed of following raw materials in parts by weight: 40 to 45 parts of medium-oil-length alkyd resin, 24 to 26 parts of terpolycyantoamino-formaldehyde resin, 12 to 14 parts of m-phenylenediamine, 6 to 8 parts of diaminodiphenyl-methane, 3 to 4 parts of calcium naphthenate, 4 to 6 parts of dimethicone, 1 to 2 parts of triphenethylphenoxypoly(ethyleneoxy)ethanol, 2 to 3 parts of ricinoleic acid, 4 to 5 parts of vinyl tri(beta-metoxyethoxy) silane, 3 to 4 parts of styrene, 8 to 10 parts of vinyl carboxylic ester, 2 to 3 parts of tributyltin chloride and 4 to 5 parts of film forming agent. The alkyd resin impregnating varnish has the advantages of compact coating membrane, fast drying, high-temperature resistance, high dampness resistance, good electric insulation property and high mechanic performance. The heat conductivity of the varnish is improved, so the varnish can work at the temperature of 200 DEG C for a long period and at the temperature of 220 DEG C for a short period. The design requirements are fulfilled.
