Description
Verfahren zum lösungsmittelfreien Verkleben von Materialien mit Kunstharzen Die Erfindung betrifft ein Verfahren zum lösungsmittelfreien Verkleben von Materialien mit Kunstharzen.Process for the solvent-free bonding of materials with synthetic resins The invention relates to a method for the solvent-free bonding of materials with synthetic resins.
Lösungsmittelfreie Klebstoffe sind bekannt. Ferner ist es bekannt, zur Herstellung von Preßmassen borhaltige Organopolysiloxane, die mit weniger als 0,5 1/o Borsäurekomplex hergestellt sind, oder auch hochsiedende Triester der Borsäure in Mengen von 0,5 111/o zu verwenden.Solvent-free adhesives are known. It is also known for the production of molding compounds boron-containing organopolysiloxanes with less than 0.5 1 / o boric acid complex are produced, or high-boiling triesters of boric acid to be used in amounts of 0.5 111 / o.
Es ist ferner ein Klebeverfahren bekannt, bei dem borhaltige Siloxane mit etwa honigartiger Konsistenz verwendet werden, wobei diese aus Dimethylpolysiloxanen mit kleinen Mengen einer Borverbindung durch Zeit und Temperatur dosierte Wärmepolymerisation hergestellt worden sind.There is also a known adhesive method in which boron-containing siloxanes with an approximately honey-like consistency, these made from dimethylpolysiloxanes with small amounts of a boron compound, heat polymerization dosed by time and temperature have been manufactured.
Die Beschichtung der zu verbindenden Teile mit dem hochviskosen Klebstoff erweist sich als schwierig, zumal erkannt wurde, daß eine Verwendung des Klebstoffs in gelöster Form Nachteile mit sich bringt. Durch Lösungsmittel wird die besondere Molekularstruktur geändert, und dieser Vorgang ist im Hinblick auf die bekannte Schwierigkeit der Lösungsmittelentfernung nur schwer rückgängig zu machen.The coating of the parts to be connected with the highly viscous adhesive proves difficult, especially since it was recognized that use of the adhesive brings disadvantages in a dissolved form. Solvent becomes the special Molecular structure changed, and this process is known in terms of Difficulty removing solvent difficult to reverse.
Diese Nachteile werden erfindungsgemäß dadurch beseitigt, daß man flüssige, borhaltige, jedoch weniger als 0,5 Molprozent Bor enthaltende Heterokondensate aus nicht vernetzten Organopolysiloxanen und Borsäure oder Organoborsäure mit einer Viskosität in der Größenordnung von 103 und 104 Centistokes auf Flächen aufbringt, dann an der Luft zu hochviskosen Polymeren mit einer Viskosität von mehr als 1.06 Centistokes kondensieren läßt und die zu verklebenden Flächen zusammenfügt.According to the invention, these disadvantages are eliminated by applying liquid, boron-containing, but less than 0.5 mol percent boron-containing heterocondensates of uncrosslinked organopolysiloxanes and boric acid or organoboric acid with a viscosity of the order of 10 3 and 10 4 centistokes to surfaces, then in air condenses into highly viscous polymers with a viscosity of more than 1.06 centistokes and joins the surfaces to be bonded together.
Man erhält durch das erfindungsgemäße Verfahren den Vorteil, daß die zu verbindenden Gegenstände nun leicht durch Tauchen oder Bestreichen beschichtet und zusammengefügt werden können.The process according to the invention has the advantage that the Objects to be connected are now easily coated by dipping or brushing and can be put together.
Die überraschenderweise festgestellte auffällige Kondensation der beschriebenen Produkte ist vermutlich auf Silanolgruppen zurückzuführen, die sich in bekannter Weise durch die Spaltung der Si-O-B-Bindung unter dem Einfluß der Luftfeuchtigkeit bilden.The surprisingly found conspicuous condensation of the products described is probably due to silanol groups, which in a known manner by the cleavage of the Si-O-B bond under the influence of atmospheric humidity form.
Beispiel 100 g eines Dimethylpolysiloxans mit einer Viskosität von ungefähr 10 000 Centistokes bei 20° C werden 1 g Borsäureanhydrid zugemischt und die Mischung bei einer Reaktionstemperatur von 120° C bis zu einer Viskosität von ungefähr 50 000 Centistokes bei 20° C in bekannter Weise kondensiert.Example 100 g of a dimethylpolysiloxane with a viscosity of about 10,000 centistokes at 20 ° C., 1 g of boric anhydride is mixed in and the mixture at a reaction temperature of 120 ° C to a viscosity of condensed approximately 50,000 centistokes at 20 ° C in a known manner.
Die gewonnenen borhaltigen Siloxane werden gut verschlossen aufbewahrt. Sie sind dann jahrelang haltbar und kondensieren an der Luft je nach Schichtdicke in Minuten oder Stunden zu hochviskosen, stark klebenden, kaltfließenden und zugleich stoßelastischen Polymeren.The boron-containing siloxanes obtained are kept tightly closed. They are then durable for years and condense in the air depending on the layer thickness in minutes or hours to highly viscous, strongly adhesive, cold-flowing and at the same time impact elastic polymers.
Durch Zusätze harzartiger Reaktionsprodukte aus dimeren und polymeren Fettsäuren und überschüssigen Polyaminen mit einer Aminzahl von 290 bis 320, die dem flüssigen Heterokondensat in katalytischen Mengen beigefügt werden, vermindert sich die Hydrolysenempfindlichkeit der Endprodukte merklich, d. h., diese verändert sich auch nach längerer Lagerung an der Luft nicht weiter nachteilig.By adding resin-like reaction products from dimeric and polymeric Fatty acids and excess polyamines with an amine number from 290 to 320, the are added to the liquid heterocondensate in catalytic amounts, reduced the hydrolysis sensitivity of the end products is noticeable, d. i.e., this changed no further disadvantageous even after prolonged storage in air.
