Abstract
The invention discloses epoxy insulating impregnating varnish for an electric generator. The epoxy insulating impregnating varnish is composed of, by weight, 110-120 parts of epoxy resin, 35-40 parts of styrene, 0.4-0.6 part of benzyl dimethylamine, 4.12-4.56 parts of maleic anhydride, 0.22-0.35 part of aluminium acetylacetonate and 85-95 parts of anhydride. With epoxy resin and styrene as foundations, the epoxy insulating impregnating varnish is free of solvent and pollution and good in safety performance and insulating performance.
Description
Technical field
The present invention relates to the insulation processing technical field of generator, especially, relate to a kind of epoxy insulation impregnating varnish for generator.
Background technology
Impregnating varnish is used for the solenoid of dip treating generator, fill the gap in insulation system and micropore, and form continuous paint film on impregnated thing surface, and make coil be bonded to a solid entirety, effectively improve the globality of insulation system, thermal conductivity, moisture resistivity, dielectric strength and physical strength.At present, solvent impregnating varnish (solids content 40%-70%) advantage that industry uses is easy to use, immersion good, runs off few when adding hot baked, and shelf-stable is cheap etc.; But flood and cure the time long (the drying varniss time is about 0.5-3h), solvent is inflammable dangerous, and causes air and environmental pollution etc.
Summary of the invention
The object of the invention is to provide a kind of epoxy insulation impregnating varnish for generator, to solve in prior art, solvent impregnating varnish dipping and the time of curing long, solvent is inflammable dangerous, and causes the problem of air and environmental pollution.
For achieving the above object, the invention provides a kind of epoxy insulation impregnating varnish for generator, be made up of the component of following parts by weight: epoxy resin 110-120 part, vinylbenzene 35-40 part, benzyldimethylamine 0.4-0.6 part, MALEIC ANHYDRIDE 4.12-4.56 part, aluminium acetylacetonate 0.22-0.35 part, acid anhydrides 85-95 part.
Further, be made up of the component of following parts by weight: described epoxy resin 115 parts, described vinylbenzene 38 parts, described benzyldimethylamine 0.5 part, described MALEIC ANHYDRIDE 4.3 parts, described aluminium acetylacetonate 0.3 part, 90 parts, described acid anhydrides.
The present invention has following beneficial effect:
This insulating impregnating varnish, based on epoxy resin and vinylbenzene, does not adopt solvent, pollution-free, and safety performance is good, has good insulating property.
