Description
Zur Metallverbindung dienende Leimfolie Es sind Leimfolien bekannt, bei denen ein kesolharz auf einen etwa o,t mm starken Papierträger aufgebracht ist. Derartige Folien dienen insbesondere zur Holzverleimung, z. B. bei der Sperrholzherstellung. Sie besitzen den Vorzug einer einfachen Handhabung bei bestmöglicher Klebung. Gegenüber den Verfahren der Verwendung irgendwelcher Tauch- und Streichleime (Naßverl-eimung) erzielen sie durch diese Eigenschaften einen erheblichen Fortschritt. Die trockenen Folien brauchen, beliebig zu,-"-schnitten, nur zwischen die zu verleimenden Stoffe gelegt und dann mittels Druck und Wärme verpreßt zu werden. Das Resolharz wird dadurch zunächst flüssig und dringt in die Holzporen ein, um anschließend auszuhärten, d.'h. in den Resitzustand überzugeh ,n. Ein weiterer Vorzug ist die genaue Dosiermöglichkeit in bezug auf die Harzmenge, die zudem durch diese Folien gleichmäßig auf der ganzen Klebefläche verteilt ist.Glue foil used for metal connection Glue foils are known in which a kesol resin is applied to a paper carrier approximately 0.1 mm thick. Such films are used in particular for gluing wood, for. B. in plywood production. They have the advantage of easy handling with the best possible gluing. Opposite to the method of using any dipping and spreading glue (wet glue) they achieve considerable progress through these properties. The dry ones Foils need to be cut as required, only between the fabrics to be glued placed and then pressed by means of pressure and heat. The resole resin is thereby initially liquid and penetrates the pores of the wood to then harden, i.e. to go into the residency state, n. Another advantage is the possibility of precise dosing in terms of the amount of resin, which is also distributed evenly through these foils all over the place Adhesive surface is distributed.
Leider eignen sich diese Leimfolien mit Papierträger nicht zu Metallverbindungeen, an die besondere Festigkeitsansprüche gestellt werden. Man hat daher in neuerer Zeit für diese Verwendung einen andern Weg beschritten. Man trägt ein festes und zweckmäßig pulverförmiges Resolharz auf die zu verbindenden Metallflächen, die vorher oder nachher zu erwärmen sind, auf, um dann bei Fixierung der Metallflächen das zuerst flüssig gewordene Resolharz durch Wärme auszuhärten. Auf diesem Wege- werden beachtliche Festigkeitswerte erreicht, die im übrigen wesentlich von den Harzeigenschaften bestimmt sind. Gegeneine universelle Verwendung derartiger fester Resolharze spricht die etwas umständliche Handhabung und gewissee Schwierigkeiten im Hinblick auf die Dosierung.Unfortunately, these glue films with paper backing are not suitable for metal connections, to which special strength requirements are placed. One has therefore in more recent Time for this use took a different path. One wears a solid and expediently powdered resol resin on the metal surfaces to be connected, which were previously or are to be heated afterwards, in order to then fix the metal surfaces first to cure the resole resin that has become liquid by means of heat. On this way- becoming Reached considerable strength values, which, moreover, depend largely on the resin properties are determined. Against a universal one Use of such solid Resole resins speak of the somewhat cumbersome handling and certain difficulties in terms of dosage.
Gemäß dieser Erfindung wird nun ein erheblicher Fortschritt dadurch erzielt, daß auf .dünnste Metall-= folien, insbesondere aus Aluminium und Eisen, -beiderseits: eine Resolharzlösung aufgetragen wird, die nach dem Trocknen einen feinen, äußerst festhaftenden Resolharzfilm auf der Metallfolie hinterläßt. Diese mit einer dünnen Schicht von festem Resolharz bedeckten Metallfolien werden als Leimfolien direkt zur Verbindung von Metallen benutzt. Dazu werden entsprechende Zuschnitte trocken zwischen die Metalle gelegt und das Ganze der Wärme bis zur Aushärtung ausgesetzt. Bei geeigneter Harzwahl können auf diese Weise bereits nach einer nur einige Minuten dauernden Erwärmung bei etwa 2oo° ohne besonderen Druck sofort äußerst feste Metallverbindungen erzielt werden. Dieses Verfahren ergibt damit auf dem j Gebiete der Metallverbindungen die gleichen Vorzüge, die Leimfolien mit Papierträger bei Holzverbindungen erreichen. Sehr gute Ergebnisse werden bei der Verbindung von Eisen bzw. Stahl und ebenso -von Aluminium nebst seinen Legierungen mit dünnsten Aluminiumfolien unter 5o ,u Stärke erhalten, die beiderseits dünnste Resolharzschichten tragen.In accordance with this invention there is now a substantial advance thereby achieved that on .thinnest metal = foils, especially made of aluminum and iron, -both sides: a resol resin solution is applied, which after drying a leaves a fine, extremely adherent resol resin film on the metal foil. These Metal foils covered with a thin layer of solid resol resin are used as Glue foils used directly to join metals. Appropriate Blanks are placed dry between the metals and the whole of the heat until it hardens exposed. With a suitable choice of resin, this can be done after only one A few minutes of warming at about 200 ° immediately without any particular pressure solid metal connections can be achieved. This procedure results in the j Areas of metal connections have the same advantages as glue foils with paper backing achieve in wood connections. Very good results will be obtained when connecting Iron or steel and also aluminum and its alloys with the thinnest Aluminum foils with a thickness of less than 5o, received the thinnest layers of resol resin on both sides wear.
