Description

Verfahren zur Herstellung hochdurchschlagfester, elastischer Isolierungen Es ist bekannt, d;aß Resolharze Lack schichten von bemerkenswerter ele!lctrischeir Isolierwirkung ergeben können. E,s hat .sich Faber gezeigt, daß diesen, Schichten auch bei den hochplastifizierten Typen noch eine derartige. Sprödiäkeit anzuhaften, pflegt, daß diese für bestimmte Zwecke, wie beispielsweise für die Tränkung von Glasgeweb,ebändern und -fod:i,en, nicht völlig .befriedigen. Die, an und für sich elastischer herstellbaren plastifizierten Harnstoffharze dagegen wei:s,en eine so erheblich niedrigere Durchschlagfestigkeit auf, daß sie für sich allein; erst recht nicht als idealer Rohstoff für diesen Anwendungszweck gelten, können.Process for the production of highly puncture-resistant, elastic insulation It is known that resole paints have layers of remarkable ele! Lctrischeir Isolation effect can result. Faber has shown himself that these layers this is also the case with the highly plasticized types. To cling to brittleness, wears that this for certain purposes, such as for the impregnation of Glass fabric, ribbons and -fod: i, en, not completely satisfied. That, in and of itself Plasticized urea resins that can be produced more elastically, on the other hand, have such a thing significantly lower dielectric strength than that on its own; above all cannot be regarded as an ideal raw material for this purpose.

Eis wurde neun gefunden, ,daß hervorragend elastische und bleichzeitig bochdurchsch:lugfeste Isolierungen, die be,i-spielsweise bei einer Foliendicke von etwa o,i mm im Mittelwert Durchschlagfestigkeiten von 8,8 bis 10,41,2V aufwei.sen, nach folgendem Verfahren hergestellt werden können.. Man, tränkt erfindungsgemäß Glasgewebebän@der oder -fodiien, für esch oder um die zu -i!solierenden Leiter igewicik edt, .in einem zwischen 2,5 und 5i010/0 Festkörper enthaltenden Tauchlack,der weiter unten beschriebenen Art, läßt -die in bewegter warmer Luft oder bei 6o° in: einem Trockenschrank restlos verdunsten und brennt s,ch,ließli,ch Idas Ganze im allglerneinen etwa 30 bis 6o Md:nuten lang bei der für die verwendeten Harze maßgeblichen Temperatur (in der Regel i70 bis a00°) ein. Der Lack selbst besteht aus geeigneten, stark plastdfizierten Resolharzen (P@henod-Formaldehy,dharzen) und plastifizierten Harnstoffh.arzen. Das -Mis;chungsverhältnis zwischen diesen p.lastifiz_ierben: Resol- und Harnstoffharzen ist aus Gründen ,der Erzielung .m@aximal,er Eigenschaften verhältnismäßig (begrenzt. Besonders .bewährt haben. sich hinsichtlich Ellastizität und Is.olierwi:rkung Mischungen von .etwa roo Teilen plastifiziertem Resolharz, etwa 6oo/oig, zu 3 bis 3o Teilen p'lastifiziertem Harnstoffharz, etwa 5o°/oigg, welche mit geeigneten Lösungsrnittedn, wie z. B. Sprit, Butanol, Glykol.äthern oder Ben@zolkohlenwasserstoffen, auf die gewünschte Tanchkons.iistenz einä stellt werden.Ice was found nine to have excellent elastic and pale penetration: peep-proof insulation which, for example, with a film thickness of about 0.1 mm, has an average dielectric strength of 8.8 to 10.41.2V, according to the following Process can be produced .. According to the invention, glass fabric tapes or forms, for or around the conductors to be insulated, are impregnated in an immersion lacquer containing between 2.5 and 5010/0 solids, which is described below Art, lets -that evaporate completely in moving warm air or at 60 ° in: a drying cabinet and burns s, ch, letli, ch Idas whole in general about 30 to 60 Md: utes long at the temperature relevant for the resins used (in usually i70 to a00 °). The paint itself consists of suitable, highly plasticized resol resins (phenod-formaldehyde, dharzen) and plasticized urea resins. The mixing ratio between these plasticizing: resol and urea resins is, for reasons of achieving maximum, proportional properties (limited. Particularly. Have proven themselves in terms of elasticity and insulation properties. Mixtures of .about 100 parts plasticized resol resin, about 600 per cent, to 3 to 30 parts plasticized urea resin, about 50 per cent, which can be reacted with suitable solvents, such as, for example, fuel, butanol, glycol ethers or benzene hydrocarbons The desired tan consistency can be set.
