Definitions
- the invention relates to a process for the production of aqueous thermosetting electrical insulating lacquers based on polyesterimides and their use as wire lacquers or as impregnating lacquers, e.g. for impregnating enamelled wire windings.
- polyesterimide solutions In order to process polyesterimide solutions well, relatively low solids contents have to be produced. Due to the specific solubility properties of PEI, phenols, cresols, xylenols, N-methylpyrolidone, etc. must be used as solvents or as solvent mixtures. These solvents are mostly non-volatile, expensive and sometimes have a very unpleasant smell. In order to avoid unpleasant smells and environmental pollution from such solvents, very complex post-combustion systems are necessary.
- aqueous systems In addition to coating electrical conductors with solvent-free resins from the melt, aqueous systems have also been proposed as environmentally friendly and economical alternatives.
- DE-OS 23 51 077 and 23 51 078 describe aqueous PEI secondary dispersions. However, these secondary dispersions have too low a solids content and also require special application devices.
- DE-OS 26 05 790 water-thinnable PEI electrical insulating lacquers are described, which can be obtained with the help of considerable Ls / P
- Amounts (5 to 30% by weight, preferably 20 to 30%) of tertiary amine and with the use of 5 to 20% by weight of auxiliary solvent are converted into an aqueous form.
- DE-OS 17 20 321 describes a process for the preparation of water-dilutable polyesterimide resins with the aid of ammonia.
- aromatic tricarboxylic anhydrides are first reacted with up to 80% of the stoichiometric amount of primary diamines which are necessary for imide formation and condensed with an excess of di- and / or trial alcohols.
- Anschlies- se nd the excess alcohol is distilled off and the condensation product with a small amount of aqueous ammonia, optionally with the addition of dialcohols heated to a temperature of about 80 ° C and then diluted the condensation product with water.
- DE-OS 27 24 913 also shows water-soluble polyesterimide resins and processes for their preparation.
- the products and manufacturing processes described herein result in products that must be adjusted to pH> 7 with amines, i.e. these products smell strongly of amines, which has an adverse effect on workplace hygiene.
- larger amounts of auxiliary solvents are used (> 10%, as can be seen from the examples).
- the present invention relates to a process for the preparation of aqueous thermosetting electrical insulating lacquers based on polyesterimides which have been obtained by condensation of aromatic tricarboxylic acid monoanhydrides, aromatic dicarboxylic acids or their esterifiable derivatives, diamines, diols and a triols containing an isocyanurate ring, which is characterized in that hydroxyl group-containing Polyesterimides with kinematic viscosities from 16 to 30 mm 2 .

- the present invention also relates to the use of these aqueous electrical insulating lacquers as wire lacquers or impregnating lacquers.
- the process according to the invention gives completely clear, water-dilutable lacquers which have improved heat levels compared to the water-dilutable lacquers obtained with tertiary amines.
- the electrical insulating varnishes according to the invention m more economical and much more environmentally friendly due to the use of cheap ammonia instead of ethanol amines. They can be applied to the substrates to be coated using customary application systems and, after baking, show that the technical properties of the conventional polyesterimide lacquers dissolved in the above-mentioned organic solvents and thus problematic with regard to their environmental impact are at least equivalent.
- polyesterimides to be used for the process according to the invention and their structural components it should be stated that the basic structure of suitable polyesterimides can be found in DE-AS 14 45 263 and DE-AS 14 55 100.
- the hydroxyl-containing polyester imide to be used according to the invention can preferably be prepared by the process described in DE-OS 14 55 182.
