Description

Verfahren zur Herstellung von Kleb- und Kittstoffen Bekanntlich sind sehr viele makromolekulare Stoffe durch ihre Zähigkeit ausgezeichnet und eignen sich deshalb als Kleb- oder Kittstoffe. Wenn man solche Stoffe, wie z. B. Kautschuk, Cellulosenitrate oder -acetate und andere Ester der Cellulose, Celluloseäther, Polyvinylester und -ätlier, Polyacrvlsäureester, zum Kleben oder Kitten von anorganischen --Materialien, wie Glas, Porzcll.ui, Metalle, verwenden will, so macht man die unangenehme Erfahrung, daß diese organischen Kleb- und Kittstoffe eine geringe Affinität zur anorganischen Oberfläche besitzen.Process for the production of adhesives and putties are known very many macromolecular substances are characterized by their toughness and are suitable therefore as adhesives or putties. If you have such substances, such as. B. rubber, Cellulose nitrates or acetates and other esters of cellulose, cellulose ethers, polyvinyl esters and ethers, polyacrylic acid esters, for gluing or cementing inorganic materials, like glass, porcelain, metal, you have the unpleasant experience that these organic adhesives and putties have a low affinity for the inorganic Own surface.

- Vorliegend wird nun ein ganz neues Verfahren angegeben, um die Affinität von den genannten makromolekularen organischen Substanzen an die anorganischen Materialien zu vergrößern. Dieses besteht darin, daß man den genannten makromolekularen Substanzen polymere Kieselsäureestcr zusetzt. Diese polymeren Kieselsäureester haben einmal anorganischen Charakter und zeigen deshalb mit ihren Restaffinitäten Verwandtschaft zii der anorganischen Oberfläche, z. B. zu der des Glases. Gleichzeitig besitzen sie aber noch so viel organischen Charakter, daß sie in die genannten hochpolymeren Stoffe sich einverleiben lassen, ohne daß eine Ausscheidung oder "Trübung erfolgt. Dieses Vermischen von polymeren Kieselsäureestern mit den makromolekularen organischen Stoffen kann entweder dadurch geschehen, daß man zu Lösungen dieser makromolekularen Stoffe in einem organischen Lösungsmittel, wie Aceton, Butylacetat, Lösungen der polymeren Kieselsäureester in gleiclieii Lösun(rsmitteln zusetzt. aus diesen Lösungen von makromolekularen Stoffen mit polymeren Kieselsäureestern lass; ii sich nach Abdunsten des Lösungsmittels Folien oder Kittsubstanzen herstellen, die eine erhöhte Affinität zur anorganischen Oberfläche besitzen.- In the present case, a completely new method is now specified for the affinity from the mentioned macromolecular organic substances to the inorganic materials to enlarge. This consists in that one of the macromolecular substances mentioned polymer silicic acid esters added. These polymeric silicic acid esters have one time inorganic character and therefore show a relationship with their residual affinities zii the inorganic surface, e.g. B. to that of the glass. Own at the same time But they still have so much organic character that they can be converted into the above-mentioned high polymer Substances can be incorporated without excretion or turbidity occurring. This mixing of polymeric silicic acid esters with the macromolecular organic ones Substances can either be done by creating solutions of these macromolecular Substances in an organic solvent such as acetone, butyl acetate, solutions of the polymeric silicic acid esters in the same solvents are added from these solutions of macromolecular substances with polymeric silicic acid esters; ii after Evaporation of the solvent can produce foils or putty substances that increase Have an affinity for the inorganic surface.

Um solche innigen Mischungen von polymeren. Kieselsäureestern mit malcromolckular en organischem Substanzen herzustellen, kann plan auch derart verfahren, daß man die monomeren Kieselsäurcester direkt den makromolekularen Substanzen zusetzt, wobei- diese unter Quellung von denselben aufgenommen werden. Durch Zusatz von Wasser werden beim längeren Stehen oder Erhitzen diese inonomeren Kieselsäureester in-polymere umgewandelt. Dabei können auch zu Lösungen der makromolekularen Stoffe in organischen Lösungsmitteln die monomeren Kieselsäurcester zugesetzt werden und dann nach Zusatz von kleinen Mengen Wasser unter nachträglichem Stehen oder Erwärmen die monomeren Kieselsäurcester in polymere übergeführt werden. Schließlich können diese polymeren Kieselsäurcester auch aus Siliciumtetrachlorid unter Zusatz von entsprechenden Mengen Alkohol hergestellt werden, wobei man ebenfalls wieder mit Lösungs. mittel verdünnen kann. Die so erhaltenen Kieselsäurcester werden dann mit den Lösungen von den genannten polymeren Substanzen zusammengegeben. Da die meisten makromolekularen organischen Stoffe gegen Chlorwasserstoff empfindlich sind, muß Sorge getragen werden, daß diese rohen hochpolymeren Kieselsä ureester durch Erwärmen oder Evakuieren möglichst vollständig von demselben befreit werden: In allen Fällen wird die Kleb- und Kitt-' kraft der genannten niakromolekularen Stoffe durch Zusätze von polymeren Kieselsäureestern wesentlich erhöht. Diese polymeren Kieselsäureester werden dabei zu den genannten Substanzen in Mengen von 5 bis 5o0'o zugesetzt. Ausführungsbeispiele i. io Gewichtsteile Celluloseäther mit einem Äthosylgehalt von 2,5 werden in i öo Teilen Aceton gelöst und zu dieser Lösung 5 Teile roher Kieselsäureäthylester zugesetzt, der ein Gemisch von verschiedenen Polymeren darstellt. Dieser letztere wird durch Eintragen von i Teil Siliciumtetrachlorid in 5 Teile 96-prozentigen Alkohol unter Ahdestillieren des Überschusses von Alkohol und Entfernen der gebildeten Chlorwasserstoffsäure im Vakuumunter Erwärmen hergestellt. Die Mischung ist als Klebstoff gebrauchsfertig. Es lassen sich aber auch weiter durch Abdestillieren von mehr oder weniger Aceton Klebstoffe von höherer Konsistenz herstellen.To such intimate mixtures of polymers. To produce silicic acid esters with malcromolecular organic substances can also be carried out in such a way that the monomeric silicic acid esters are added directly to the macromolecular substances, whereby these are absorbed by them with swelling. When water is added, these inonomic silicic acid esters are converted into polymers on prolonged standing or heating. The monomeric silicic acid esters can also be added to solutions of the macromolecular substances in organic solvents and the monomeric silicic acid esters can then be converted into polymers after adding small amounts of water with subsequent standing or heating. Finally, these polymeric silicic acid esters can also be prepared from silicon tetrachloride with the addition of appropriate amounts of alcohol, again with solution. can dilute medium. The silicic acid esters obtained in this way are then combined with the solutions of the polymeric substances mentioned. Since most macromolecular organic substances are sensitive to hydrogen chloride, care must be taken that these crude, high-polymer silicic acid esters are freed from the same as completely as possible by heating or evacuation: in all cases the adhesive and cementing power of the niacromolecular substances mentioned is reduced Additions of polymeric silicic acid esters increased significantly. These polymeric silicic acid esters are added to the substances mentioned in amounts of 5 to 50%. Embodiments i. 10 parts by weight of cellulose ether with an ethosyl content of 2.5 are dissolved in 10 parts of acetone and 5 parts of crude silicic acid ethyl ester, which is a mixture of different polymers, are added to this solution. The latter is prepared by introducing 1 part of silicon tetrachloride into 5 parts of 96 percent alcohol while distilling off the excess alcohol and removing the hydrochloric acid formed in vacuo with heating. The mixture is ready to use as an adhesive. However, adhesives of higher consistency can also be produced by distilling off more or less acetone.

2: io Teile Cellulosetriacetat werden in i oo Teilen Chloroform gelöst und zu dieser Lösung 3 Teile roher Kieselsäurebutylester zugegeben. Das Gemisch von polymeren Estern wird durch -Eintragen von Siliciumtetrachlorid in die fünffache 14Zeng@ feuchten Butylalkohol unter Abdestillieren des überschusses desselben und Entferden., der Chlorwasserstofsäure im Vakuum gewonnen. Aus der fertigen Mischung können auch wieder durch Abdestillieren von Chloroform Klebstoffe höherer Konsistenz gewonnen werden.2: 100 parts of cellulose triacetate are dissolved in 100 parts of chloroform and 3 parts of crude silicic acid butyl ester were added to this solution. The mixture of polymeric esters is increased by five times the amount of silicon tetrachloride 14Zeng @ moist butyl alcohol while distilling off the excess of the same and Removal., The hydrochloric acid obtained in vacuo. From the finished mixture can also be restored by distilling off chloroform adhesives of higher consistency be won.

3. i o Teile technisches Celluloseacetat mit 2,5 Acetylgruppen werden in zoo Teilen Ace- I ton gelöst und zu dieser Lösung io Teile I tnonomerer Kieselsäuremethylester zugegeben. Es werden dann geringe Mengen Wasser zugefügt, bis gerade eine Trübung eintritt, "und erwärmt. Dadurch wird der monomere Kieselsäureester in polymere Kieselsäureester verwandelt. Das fertige Gemisch kann dann durch Abdestillieren' von mehr oder weniger Aceton wieder konzentriert werden.3. i o parts of technical cellulose acetate with 2.5 acetyl groups will be dissolved in zoo parts of acetone and added to this solution 10 parts of non-monomeric silicic acid methyl ester admitted. Small amounts of water are then added until it just becomes cloudy enters, "and heated. This turns the monomeric silicic acid ester into polymeric silicic acid ester transformed. The finished mixture can then by distilling off more or less Acetone to be concentrated again.

4. iö Teile Polyvinylacetät werden in ioo Teilen Aceton gelöst und dazu 5 Teile rohe Polykieselsäureäthylester zugegeben,. Diese werden aus monomerem Kieselsäureäthylester erhalten dadurch, daß man 5 Teile des letzteren mit : Teilen Wasser erwärmt. Aus der fertigen Mischung wird wieder Aceton teilweise abdestillicrt, um einen Klebstoff höherer Konsistenz zu erhalten.4. 10 parts of polyvinyl acetate are dissolved in 100 parts of acetone and 5 parts of crude polysilicic acid ethyl ester were added. These are made from monomeric Silicic acid ethyl ester obtained by mixing 5 parts of the latter with: parts Water heated. Part of the acetone is again distilled off from the finished mixture, to get a higher consistency glue.

5. 5 Teile Kautschuk werden in aoo Teilen Benzol gelöst und dazu a Teile rohe Kieselsäurepropylester zugegeben, die aus Siliciuintetrachlorid und Propylalkohol analog Beispiel i erhalten werden.
