Problems solved by technology
However, the modified polyester resin of this kind of insulating paint is actually an ordinary alkyd resin, and no modified raw materials have been found, and the curing agent is amino resin
That is, alkyd polyurethane resin is only added to the traditional amino-alkyd system insulating varnish. The composition of this kind of insulating varnish is complicated and costly, and it is not suitable for promotion.

The invention relates to epoxy ester baking insulating paint. The epoxy ester baking insulating paint is characterized by comprising the following components of, by weight, 60-85 parts of a self-made epoxy ester resin solution, 10-30 parts of a butylated amino resin, 0.1-2.0 parts of a lead naphthenate liquid and 0.1-2.0 parts of a cobalt naphtenate liquid. The self-made epoxy ester resin solution comprises ingredients of 20-40 parts of an E12 epoxy resin, 15-40 parts of linoleic acid, 5-10 parts of reflux xylene, 25-45 parts of xylene and 5-10 parts of butanol. The epoxy ester baking insulating paint has the advantages that the self-made epoxy ester resin solution and the butylated amino resin are mixed to prepare the epoxy ester baking insulating paint, physical and chemical properties and electrical properties of the paint can meet product standards and usage requirements of users; and the epoxy ester baking insulating paint has the advantages of being good in heat-resisting performance, oil resistivity, chemical resistance, adhesive force, flexibility, moisture resistance, salt mist resistance, mildew resistance and electrical property, low in baking temperature (120 DEG C), convenient to construct and high in beakdown strength index.
Description
technical field [0001] The invention belongs to coatings, in particular to an epoxy ester drying insulating varnish. Background technique [0002] Ordinary insulating varnishes such as ester glue drying insulating varnish and phenolic drying insulating varnish belong to Class A insulating varnish, with a heat-resistant temperature of 85°C, a narrow application range, and electrical properties that cannot meet the requirements; alkyd drying insulating varnish belongs to Class B insulating varnish. Its electrical properties can meet the requirements of general insulating varnishes, but its moisture resistance, salt spray resistance and mildew resistance are not good, and its heat resistance and wet breakdown strength cannot meet the high index requirements, so it is not suitable for use in humid tropics. Coating of electrical appliances, motors, instruments and other shells. Patent application number: 201110456280.3 discloses an insulating varnish for electrical appliances an...
