Definitions
- the invention relates to an insulating tape for insulating stator coils in electrical machines, in particular the tape accelerator in the tape adhesive of the insulating tape, which is used for a winding tape insulation system.
- stator and in some cases also the rotor have insulating systems with windings.
- an insulating tape is wound around a conductor or a conductor bundle.
- the insulating tape comprises an applied on a flexible support such as film or glass cloth, surface breakdown ⁇ solid inorganic material such as mica platelets and / or fine mica layers, which connected to the carrier and each other and optionally with a final cover layer and or ei ⁇ ner further layer by means of a tape adhesive is.
- a flexible support such as film or glass cloth
- surface breakdown ⁇ solid inorganic material such as mica platelets and / or fine mica layers
- This tape adhesive comprises a dissolved and / or finely divided tape accelerator.
- the belt accelerator serves to gel a low-viscosity impregnating resin, which is applied to the stator windings, for example in a vacuum pressure impregnation (VPI). After gelling at elevated temperature, the impregnated stator windings are thermally cured in the laminated stator core.
- VPI vacuum pressure impregnation
- Such an insulating tape is known from DE 38 24 254 AI be ⁇ known. From EP 0424376B1 corresponding tape adhesive and tape accelerator are known which have sufficient Lagerstabi ⁇ quality.
- the disclosed therein tape adhesive are the 1: 4 molar Additi ⁇ modulation products from bisphenols, especially bisphenol-A, and cycloaliphatic epoxy resins, especially 3,4-epoxycyclohexylmethyl-3,4-epoxycyclohexanecarboxylate.
- EP 0424376B1 discloses that the associated band accelerator is preferably a 1: 3 molar adduct of trimethylolpropane triacrylate and N-ethylpiperazine.
- the band accelerator and / or the adhesive tape in the mica tape composite are preferably chemically equipped such that when stored at room temperature and no premature curing unge ⁇ wanted occurs. This ensures the workability of the mica tape.
- the gelation of the glycidyl ether-based epoxy resin takes place very rapidly, since terminal oxirane functionalities in combination with acid anhydrides undergo very rapid polymerization.
- the desired storage stability of the non-impregnated mica tape and the rapid gelation of the impregnated stator can finally so ⁇ probably realize.
- phthalic anhydride-free or even anhydride-free epoxy-based VPI resins find use.
- the object of the present invention is therefore to provide an insulating tape and in particular a tape accelerator for an insulating tape, which can be used in anhydride-free VPI resins.
- the object and object of the present invention is therefore an insulating tape with a tape adhesive in which at least one tape accelerator is dissolved and / or finely divided, wherein the at least one tape accelerator is an imidazole and / or a pyrazole and / or a derivative of an imidazole and / or a derivative of a pyrazole.
- a derivative is a chemical derivative herein designated net, that is a derived substance or a derivative Ver ⁇ bond, of one or more hydrogen atoms can be prepared from the parent compound, that is, for example, imidazole and / or pyrazole, by substitution. Substitution can take place in many different chemical ways.
- the present invention is an insulating tape with a tape adhesive in which a Bandbeschleuni- ger contained and / or finely divided, which contains an adduct of at least one imidazole and / or at least one pyrazole with at least one acrylate and / or an adduct ei ⁇ nes or more imidazole derivative (s) and / or one or more pyrazole derivative (s) with one or more
- Acrylate derivative (s) is. Any combinations of derivatives and parent compounds can form the adduct.
- the adduct itself is also formed by derivatization, so is itself again a derivative.
- the heterocycle is a preferably at relatively low temperatures melting and / or liquid at room temperature ⁇ -nitrogen heterocycle having 1 to 4 nitrogen atoms in the ring.
- imidazoles such as the ⁇ -2-methylimidazole (CAS No. 693-98-1) or the 1H-imidazole (CAS No. 288-32-4), the ⁇ -2-ethylimidazole (CAS No. 1072-62-4), ⁇ -2-propylimidazole (CAS No. 50995-95-4), 1H-2-isopropyl-azazole (CAS No. 36947-68-9), ⁇ -2-butylimidazole (CAS No. 50790-93-7), ⁇ -2-iso-butylimidazole (CAS No. 61491-92-7), ⁇ -2-tert-butylimidazole (CAS No.
- phthalic anhydride-containing impregnating resins as are known from EP 0424376 Bl, as strip adhesive, the 1: 4 molar addition products of bisphenols, especially of bisphenol-A, and cycloaliphatic epoxy resins, in particular of 3,4-epoxycyclohexylmethyl-3, 4-
- Epoxycyclohexanecarboxylate disclosed.
- the tape adhesive described therein contains in its theoretical molecular structure after quantitative conversion only cycloaliphatic
- Trimethylolpropane triacrylate and N-ethylpiperazine contains by the underlying aza - Michael reaction theoretically three terminal, tertiary substituted piperazine nitrogen atoms.
- Triacrylates but especially of the tetra- and penta / hexaacrylates, with ⁇ -2-methylimidazole, 1H-2-ethylimidazole, ⁇ -2-propylimidazole, ⁇ -2-iso-propylimidazole, ⁇ -2-butylimidazole, ⁇ - 2-iso-butylimidazole, 1H-2-phenylimidazole and lH-2-ethyl-4-methylimidazole particularly ⁇ terestante compounds as a tape accelerator, because a) the achievable by anionic polymerization glass transition temperatures
- Diglycidyletherbasis are very much higher than Ver ⁇ application of N-methylpiperazine and N- Ethylpiperazinaddukte of TMPTAs b) not acide alkyl / gel and cure acylimidazoles
- L-methyl-2-alkylimidazoles are not vacuum-stable per se and even at room temperature very thin liquid; They can therefore very easily migrate in vacuo at elevated temperature during the evacuation and pre-drying of the stators to imoniagnie ⁇ leaders from the Isolierbandkleber. Therefore, the acrylates derivatized imidazoles are a preferred embodiment of the invention.
- the covalent attachment of the ⁇ -2-alkylimidazoles at the ⁇ -position in particular of the ⁇ -2-methylimidazole, 1H-2-ethylimidazole, ⁇ -2-propylimidazole, 1H-iso-propylimidazole, 1H-2-ethyl-4- Methylimidazoles, ⁇ -2-butylimidazoles, ⁇ -2-isobutyl-imidazoles and ⁇ -2-tert-butylimidazoles, to the previously used TMPTA, for example via an aza-Michael coupling, it is possible to use the N- unsuitable for phthalic anhydride epoxy resins.
- phthalic anhydride-free glycidyl ether epoxy resins Due to the high vapor pressure of the 2-alkylimidazoles and the high fluidity, however, a dispersion of small imidazole molecules and / or imidazole derivatives in the tape adhesive with the associated with later danger that the evacuation (70 ° C, 0.1 mbar for up to 72 hours) leads to evaporation or migration of the volatile alkylimidazole and this accumulates at cold ⁇ ren bodies.
- adducts of ⁇ -2-methylimidazole, 1H-2-ethylimidazole, ⁇ -2-propylimidazole, ⁇ -2-iso-propylimidazole and ⁇ -2-butylimidazole or branched ⁇ -2-isobutylimidazole and ⁇ -2 tert-Butyl imidazole with acrylates leads to a cost saving in the final structure as well as an increase in the network density by the structural number of polymerization initiators using higher acrylates such as PETA and DPHA.
- the vapor pressures of the alkyl imidazoles at elevated temperatures et ⁇ are adversely, in particular the vapor pressure of advanta- adhere l-alkyl-2-Methylimidazole is relatively high, so that during prolonged Evakuierphasen at elevated temperatures, such as They are now used in the manufacture of electrical machinery before the VPI impregnation of the stators about for predrying partially used today, a partial expulsion of any used imidazoles from the tape adhesive is to be feared.
- alkyl imidazoles ie generally the smaller imidazole derivatives, which are generally volatile at elevated temperatures, have proven to be very efficient band accelerators.
- a Bandbe ⁇ accelerator which is an adduct of a lH-imidazole derivative
- such a tape adhesive shows a vapor pressure less than 10 ⁇ 4 mbar at 70 ° C, and a high dynamic viscosity.
- the 1H-alkyl-imidazoles and / or the 1H-alkyl-pyrazoles are derivatized, for example, with acrylates.
