Description
Verfahren zur Herstellung dünner Isolierstoffolien Zusatz zum Patent 1089 024 Vorliegende Erfindung bezieht sich auf ein Verfahren zur Herstellung dünner, insbesondere unter 6 u starker, elektrisch, vorzugsweise dielektrisch beanspruchter Isolierstoffolien, die zunächst durch einen auf einer imprägnierten Trägerfolie aufgebrachten Lackfilm gebildet werden und dann von diesem Träger abgelöst werden, nach Patent 1089 024, wobei die Trägerfolie vor dem Lackieren mit einem hochschmelzenden Kohlenwasserstoff, z. B. Hartwachs oder Polyäthylen, imprägniert wird.Process for the production of thin insulating foils Addition to patent 1089 024 The present invention relates to a process for the production of thin, in particular under 6 u thick, electrically, preferably dielectrically stressed insulating foils, which are first formed by a lacquer film applied to an impregnated carrier foil and then by this Carriers are detached, according to patent 1089 024, the carrier film prior to painting with a high-melting hydrocarbon, e.g. B. hard wax or polyethylene, is impregnated.
Durch das Auftragen des hochschmelzenden Kohlenwasserstoffs soll erreicht werden, daß sich die Dünnfolie nicht so weit mit der Trägerfolie verbindet, daß sie danach nur mehr sehr schwer oder überhaupt nicht von dieser gelöst werden kann. Gleichzeitig sollen die Poren im Trägermaterial von dem überzug ausgefüllt werden, wodurch eine glatte Oberfläche erzielt wird. Es hat sich nun herausgestellt, daß es sehr wichtig ist, das Imprägniermittel in einer ganz bestimmten Menge aufzubringen, da einerseits bei einer zu geringen Imprägniermittelmenge die Poren nicht genügend ausgefüllt werden und außerdem die Lackschichten sich mit Teilen der Trägerfolie zu stark verbinden und andererseits bei zu großer Imprägniermittelmenge und der dann entstehenden zu starken Wachsschicht diese abblättert und sich beim Ablösen der Dünnfolien vom Träger zusammen mit der Dünnfolie ablöst, was ebenfalls unerwünscht ist.The aim is to achieve by applying the high-melting hydrocarbon be that the thin film does not bond so far with the carrier film that it can then only be removed from this with great difficulty or not at all. At the same time, the pores in the carrier material should be filled with the coating, whereby a smooth surface is achieved. It has now been found that it is very important to apply the impregnating agent in a very specific amount, because, on the one hand, if the amount of impregnating agent is too low, the pores are insufficient are filled and also the lacquer layers with parts of the carrier film too strong and, on the other hand, if the amount of impregnating agent is too large and the then the resulting too thick layer of wax will flake off and become detached the thin film separates from the carrier together with the thin film, which is also undesirable is.
Es wird deshalb bei dem eingangs beschriebenen Verfahren gemäß der Erfindung der Träger mit einer solchen Menge des hochschmelzenden Kohlenwasserstoffs imprägniert, daß auf beiden Seiten des Trägers Imprägniermittelschichten in der Stärke von etwa 1/2 bis 1 [, entstehen.It is therefore in the method described at the beginning according to Invention of the carrier with such an amount of the refractory hydrocarbon impregnated that on both sides of the carrier impregnating agent layers in the Thickness of about 1/2 to 1 [arise.
Das Imprägnieren der Trägerfolien erfolgt, wie bereits im Hauptpatent beschrieben, dadurch, daß die Trägerfolien im aufgewickelten Zustand als Rolle mit dem heißen, flüssigen Imprägniermittel getränkt werden. Anschließend werden sie in heißem Zustand abgespult und zur Glättung über eine hochglanzpolierte wassergekühlte Walze geführt. Um nun die gewünschte Imprägniermittelschichtdicke zu erzielen, kann man nun bei gleichmäßiger Aufspulung der zu imprägnierenden Rolle die in die Rolle eindringende Imprägniermittelmenge durch die Aufspulhärte steuern, wodurch gleichzeitig die Imprägniermittelschichtstärke bestimmt wird. Die Aufspulhärte kann gemessen werden durch die Eindrücktiefe einer Kugel in die aufgespulte Rolle. Als besonders geeignet hat sich z. B. bei einer 150 mm breiten Rolle mit 200 mm Durchmesser, die auf einen 75-mm-Stahlkern gewickelt war und aus unlackierten 1.2 #t dickem Kondensatorpapier der Satinage A bestand, eine Aufspulhärte erwiesen, die bei einer Kugel von 10 mm Durchmesser bei 5 kg Belastung eine Eindrucktiefe von 0,6 mm ergab. Die aufgenommene Wachsmenge beträgt hierbei etwa 3 g/m2.The impregnation of the carrier films takes place as in the main patent described, in that the carrier films in the wound state as a roll with soaked in the hot, liquid impregnation agent. Then they will unwound when hot and for smoothing over a highly polished water-cooled Roller guided. In order to achieve the desired impregnating agent layer thickness, can one now with even winding of the roll to be impregnated into the roll Control the amount of impregnating agent penetrating through the winding hardness, thereby simultaneously the thickness of the impregnating agent is determined. The winding hardness can be measured are caused by the depth that a ball is pressed into the coiled roll. As special suitable has z. B. with a 150 mm wide roll with a diameter of 200 mm, the was wound on a 75mm steel core and made of unpainted 1.2 #t thick capacitor paper the Satinage A consisted of a winding hardness that was 10 mm for a ball Diameter with a load of 5 kg resulted in an indentation depth of 0.6 mm. The recorded The amount of wax here is around 3 g / m2.
