Abstract
The invention provides high-temperature-resistant amino resin impregnating varnish and a preparation method thereof. The impregnating varnish is prepared from the following raw materials in parts by weight: 32-35 parts of 583-2 amino resin, 3-4 parts of unsaturated polyester resin, 5-7 parts of organic silicon resin, 2-3 parts of calcium naphthenate, 20-24 parts of xylene, 4-5 parts of methyl ethyl ketone, 2-3 parts of tetraethylenepentamine, 4-6 parts of maleic anhydride, 1-2 parts of monobutyltin oxide, 1-2 parts of tert-Butyl peroxybenzoate, 6-9 parts of butadiene, 4-5 parts of poly(propylene glycol) acrylate, 9-10 parts of alkylphenol ethoxylate phosphate, and 4-5 parts of film forming agent. The impregnating varnish can be used for a long time without yellowing or bubbling in a high-temperature environment, can be widely applied to impregnating insulation of medium-small motor coils, transformers, rectifiers and other electrical appliance coils.
