Description
Klebstoff aus natürlichem oder künstlichem Kautschuk auf der Basis von Polydienen Die Erfindung betrifft einen Klebstoff mit hoher Binde- und Hitzefestigkeit, wie er vor allem in der lederverarbeitenden Industrie benötigt wird.Natural or synthetic rubber based adhesive of polydienes The invention relates to an adhesive with high bonding strength and heat resistance, as it is mainly needed in the leather processing industry.
Um Klebstoffe mit hoher Binde- und Hitzefestigkeit zu erhalten, verwendete man bisher Lösungen von Natur- und Kunstkautschuken, denen Isocyanate in einer Größenordnung von 5 bis 10% zugefügt wurden.To obtain adhesives with high bond strength and heat resistance, used one hitherto solutions of natural and synthetic rubbers, which isocyanates in an order of magnitude from 5 to 10% were added.
Diese auf diese Weise erhaltenen Kleber hatten zwar eine erhöhte Binde- und Hitzefestigkeit, jedoch hat es sich bei der praktischen Verarbeitung als Nachteil herausgestellt, daß solche Mischungen nur eine begrenzte Haltbarkeit aufwiesen und schon nach verhältnismäßig kurzer Zeit zu koagulieren beginnen. Da üblicherweise immer mehr an Kleber angesetzt wurde, als in einem bestimmten Zeitraum benötigt wurde, entstehen durch den koagulierenden Rest, der als Klebstoff nicht mehr verwendet werden konnte, unnötige Verluste> Ferner werden durch das dauernde Ansetzen neuer Klebstoffmengen die einzelnen Ansätze in der Zusammensetzung verschieden ausfallen, so däß auch Unterschiede in der Klebkraft in Kauf genommen werden mußten.These adhesives obtained in this way had an increased binding and heat resistance, however, it has been found to be disadvantageous in practical processing found that such mixtures had only a limited shelf life and begin to coagulate after a relatively short time. Since usually more and more glue was applied than needed in a certain period of time are caused by the coagulating residue that is no longer used as an adhesive unnecessary losses Adhesive amounts of the individual approaches in the composition are different, so that differences in bond strength also had to be accepted.
So haben Klebstoffe auf der Basis von Naturkautschuk öder von Polybutylnitril bei Zusatz von 5 bis 10% Isocyanat nur eine Haltbarkeit von 60 bis 90 Minuten, während solche Klebstoffe auf der Basis von Chlorbutadien eine Haltbarkeit von 5 bis 6 Stunden haben.So have adhesives based on natural rubber or polybutyl nitrile with the addition of 5 to 10% isocyanate only a shelf life of 60 to 90 minutes, while Such chlorobutadiene-based adhesives have a shelf life of 5 to 6 hours to have.
Es wurde nun versucht, Klebstoffe möglichst auf der Basis von natürlichem oder künsflichen Kautschuken zu finden, die den damit bereiteten Klebern die erwünschte Binde- und Hitzefestigkeit verleihen, jedoch mindestens 1 Jahr, ohne Koagulierung und ohne ihre Klebkraft einzubüßen, haltbar sind. Dadurch würde ein dauerndes neues Zubereiten beim Verbraucher in Wegfall kommen, es würden keine Verluste durch vorzeitiges Unbrauchbarwerden entstehen, und der Klebstoff könnte immer in gleicher Qualität hergestellt werden.Attempts have now been made to use natural adhesives as much as possible or to find synthetic rubbers that give the adhesives prepared with them the desired Provide binding and heat resistance, but at least 1 year, without coagulation and are durable without losing their adhesive strength. This would create a permanent new one There is no longer any need to prepare food for the consumer; there would be no losses due to premature use It becomes unusable and the adhesive could always be of the same quality getting produced.
Es wurde nun gefunden, daß man zu solchen Klebstoffen kommt, wenn bestimmte Metallverbindungen den Lösungen von natürlichen oder künstlichen Kautschuken auf Polydienbasis oder Mischungen derselben einverleibt werden.It has now been found that such adhesives can be obtained when certain metal compounds the solutions of natural or synthetic rubbers based on polydiene or mixtures thereof.
Diese erfindungsgemäßen Klebstoffe besitzen neben einer erhöhten Hitzebeständigkeit auch eine wesentlich erhöhte Anfangsbindefestigkeit. Diese Eigenschaften werden vor allem in der lederverarbeitenden Industrie geschätzt, da dort die meisten Verklebungen sofort einer Einwirkung von Wärme unterworfen werden. In diesen Industriezweig werden beispielsweise aufgeklebte Sohlen sofort gefräst, und die bei diesem Vorgang entstehende Wärme hat bisher zum Teil dazu geführt, die verklebten Stellen wieder zu trennen. Mit den erfindungsgemäßen Klebern aufgeklebte Sohlen trennen sich auch in der Wärme nicht, müssen also vor dem Fräsen nicht erst abgelagert werden, um den Bindevorgang beenden zu lassen, sondern es kann sofort nach Aufbringung der Sohlen gefräst werden, was ein schnelleres und rationelleres Arbeiten ermöglicht. Als Zusatz für den erfindungsgemäßen Klebstoff werden die mit organischen Radikalen substituierten Metallhydroxyde der III. und IV. Gruppe des Periodischen Systems verwendet, die durch die allgemeine Formel R1 Me (0R2) x dargestellt werden, wobei R1 Wasserstoff, Alkyl, Aryl, Aralkyl, Alkaryl, O-Alkyl, O-Aryl und R2 Alkyl, Aryl, Aralkyl, O-Alkyl und O-Aryl, x eine ganze Zahl größer als 1 und Me ein Metall der III. und IV. Gruppe des periodischen Systems ist.These adhesives according to the invention have, in addition to increased heat resistance also a significantly increased initial bond strength. These properties are especially valued in the leather processing industry, as this is where most of the bonds are made immediately exposed to heat. Be in this industry For example, glued-on soles are milled immediately, and the resulting from this process Up to now, heat has partially led to the stuck areas being separated again. Soles glued on with the adhesives according to the invention also separate when exposed to heat not, so they do not have to be deposited before milling for the binding process to finish, but it can be milled immediately after applying the soles, which enables faster and more rational work. As an additive for the invention The metal hydroxides substituted with organic radicals are used as adhesives III. and IV. Group of the Periodic Table used by the general Formula R1 Me (0R2) x are represented, where R1 is hydrogen, alkyl, aryl, aralkyl, Alkaryl, O-alkyl, O-aryl and R2 alkyl, aryl, aralkyl, O-alkyl and O-aryl, x is one integer greater than 1 and Me a metal of III. and IV. group of periodic System is.
Geeignete Metallverbindungen sind die organischen Oxydderivate des Titans, des Siliziums und des Aluminiums. Zum Beispiel können folgende Verbindungen zweckmäßiger Weise in Mengen von 0,5 bis 10 Gewichtsprozent zugesetzt werden Aluminiumtriäthyloxyd, Aluminiumtributyloxyd, Aluminiumtriphenyloxyd, Titantetrabutyloxyd.Suitable metal compounds are the organic oxide derivatives of Titanium, silicon and aluminum. For example, the following compounds aluminum triethyloxyd is expediently added in amounts of 0.5 to 10 percent by weight, Aluminum tributyl oxide, aluminum triphenyl oxide, titanium tetrabutyl oxide.
Auch die Metallverbindungen der Diketone, die Salze der Enolform darstellen,
können verwendet werden. Als Beispiel sei das Aluminiumsalz des Acetylacetons erwähnt.
_
Manche - Metallverbindungen der obengenannten Art bilden polymere Formen, die -in-
gleicher Weise den K_lebgtofen zugesetzt werden können.
Ferner können zur Erhöhung der Elastizität Polykondensationsharze, sei es auf dem Gebiet der in Methanol löslichen Polyamide oder Phenolharze, vorgesehen sein.Furthermore, to increase the elasticity, polycondensation resins, be it in the field of methanol-soluble polyamides or phenolic resins be.
Ohne die Erfindung begrenzen zu wollen, sei im folgenden nur zur Erläuterung ein Ausführungsbeispiel der erfindungsgemäßen Klebstoffe gebracht, Zwar sind schon Klebemittel vorgeschlagen worden, die Titanester enthalten, die jedoch als Harzkleber Siliconharze enthalten sollen. Diese Klebemittel haben den Hauptnachteil, daß die Siliconharze mit der Zeit auspolymerisieren und dadurch irreversibel verhärten. Eine größere Lagerfähigkeit ist diesen Klebern abzusprechen. Im Gegensatz hierzu werden bei der vorliegenden Erfindung Klebstoffe auf der Basis der Polydiene vorgeschlagen, die auch nach der Trocknung ihre Elastizität beibehalten und bessere Lagerfähigkeit aufweisen. Ein Aushärten zu spröden Massen durch weitergehende Polymerisaten ist hier nicht zu befürchten. Für bestimmte Klebungen, wie z. B. Leder auf Leder, ist diese Restelastizität sehr erwünscht.Without wishing to limit the invention, the following is only for explanation brought an embodiment of the adhesives according to the invention, although they are already Adhesives have been proposed that contain titanium esters, but are used as resin adhesives Should contain silicone resins. These adhesives have the main disadvantage that the Silicone resins polymerize over time and thus harden irreversibly. A longer shelf life is to be discussed with these adhesives. In contrast to this the present invention proposes adhesives based on polydienes, which retain their elasticity even after drying and have a better shelf life exhibit. A hardening to brittle masses by advanced polymers is not to be feared here. For certain bonds, such as B. leather on leather is this residual elasticity is very desirable.
Beispiel In 78 kg einer Mischung von gleichen Teilen Toluol, Äthylacetat und Benzin vom Siedebereich 60 bis 110°C werden 15 kg Chlorbutadien gelöst und nach der Lösung unter Rühren 1 kg Terpenphenolharz und 3 kg handelsüblich modifizierte Phenolharze eingebracht. Nachdem eine einheitliche Mischung entstanden ist, werden unter weiterem Rühren 0,6 kg feines Zinkoxyd, 2 kg monomeres Titantetrabutylat und 0,4 kg weißer Ruß zugegeben. Nach Entstehen einer homo Masse ist der erfindungsgemäße Klebstoff- verwendbar.Example In 78 kg of a mixture of equal parts of toluene and ethyl acetate and gasoline with a boiling range of 60 to 110 ° C, 15 kg of chlorobutadiene are dissolved and after the solution with stirring 1 kg of terpene phenolic resin and 3 kg of commercially modified Phenolic resins introduced. After a uniform mixture is created, be with further stirring 0.6 kg of fine zinc oxide, 2 kg of monomeric titanium tetrabutylate and 0.4 kg of white carbon black was added. After the creation of a homo mass, that is according to the invention Can be used with adhesive.
