Description

Korrosionsschutzpapier Nach dem Stand der Technik ist es bekannt, Metallgegenstände durch Luft- und wasserdichte Papiere zu schützen, die zwischen der Metalloberfläche und der inneren Seite des umgebenden Papiers eine alkalisch passivierende Atmosphäre schaffen. Die bisher zu solchem Schutz vorgeschlagenen Stoffe sind unter anderem wasserlöslich und verhindern durch diese Auflösung in der auf dem Metall okkludierten Wasserschicht die Korrosion.Corrosion protection paper According to the state of the art, it is known Protect metal objects with airtight and watertight papers that are between the metal surface and the inner side of the surrounding paper are alkaline Create a passivating atmosphere. The ones previously proposed for such protection Substances are, among other things, water-soluble and prevent this dissolution in corrosion of the water layer occluded on the metal.

Es wurde nun gefunden, daß man Papier zum Korrosionsschutz verwenden kann, das einen offenen Durchtritt der Luft zum Metallgegenstand gestattet, sich aber dadurch auszeichnet, daß es keinerlei aggressive Säuren oder Salze enthält, wohl aber auf der Metalloberfläche sowohl reduzierend einwirken und eine alkalisch eingestellte Oberfläche schaffen kann.It has now been found that paper can be used for corrosion protection that allows an open passage of air to the metal object but is characterized by the fact that it does not contain any aggressive acids or salts, but both have a reducing and an alkaline effect on the metal surface set surface can create.

Diese reduzierenden und alkalischen Stoffgemische bewirken, daß selbst feinste Metalloxydhäutchen wieder zu Metall reduziert werden und auf diese Weise eine elektrolytische Auflösung der Metallkörner der zu schützenden Gegenstände stattfinden kann. Sie sind in der Lage, eine Oxydation durch die Bildung andersartiger Verbindungen, wie sie z. B. beim Anlaufen auftreten, infolge ihrer reduzierenden Eigenschaften zu verhindern.These reducing and alkaline mixtures of substances cause even finest metal oxide skins are reduced back to metal and in this way an electrolytic dissolution of the metal grains of the objects to be protected take place can. They are able to prevent oxidation by forming other types of compounds, how they z. B. occur when starting, due to their reducing properties to prevent.

Gegenstand der Erfindung ist einmal die Forderung, vorzugsweise keinen im sauren Aufschlußverfahren hergestellten Zellstoff zu verwenden, weil dieser sonst noch Säurereste in den Cellulosefasern enthält, die bei längerer Lagerung die Metalloberfläche oxydieren und damit Anlaß zur Korrosion geben. Es gehört weiter zum Gegenstand der Erfindung, als Bindemittel der Zellstoffasern bei der Blattbildung auf der Papiermaschine organische Stoffe einzusetzen, die hochkationaktive Eigenschaften besitzen und somit die aktiven Stellen der Metallkörner nicht angreifen können. Damit ergibt sich auch eine Passivierung an den Berührungspunkten zwischen Metallfläche und erfindungsgemäßem Papier. Schließlich müssen in dem Korrosionsschutzpapier noch Hilfsmittel vorhanden sein, die mit einem stark reduzierenden Charakter auf die Metalloberfläche wirken.The subject of the invention is once the requirement, preferably none to use pulp produced in the acidic digestion process, because this would otherwise still contains acid residues in the cellulose fibers, which can damage the metal surface after prolonged storage oxidize and thus give rise to corrosion. It still belongs to the subject of Invention, as a binder of the pulp fibers in sheet formation on the paper machine to use organic substances that have highly cationic properties and thus cannot attack the active sites of the metal grains. This also results a passivation at the points of contact between the metal surface and the invention Paper. Finally, aids must also be present in the anti-corrosive paper which have a strongly reducing character on the metal surface.

Es wurde also gefunden, daß durch eine Kombination gewisser säurefrei hergestellter Zellstoffe in Verbindung mit kationaktiven Bindemitteln und gleichzeitiger oder nachträglicher Belegung mit Gemischen verschiedener, als Inhibitoren entwickelter Stoffe die Korrosion verhindernde Einwickelpapiere erhalten werden können.It has thus been found that by a combination, certain acid-free produced cellulose in connection with cationic binders and at the same time or subsequent coating with mixtures of different inhibitors developed Substances that prevent corrosion wrapping paper can be obtained.

Die Arbeiten haben ergeben, daß jegliche bei der Herstellung von Zellstoff für die Einwickelpapiere erforderlichen Chemikalien säurefrei und salzfrei sein müssen und die verwendeten Zellstoffe keine oxydativen Reste enthalten dürfen. Bei der Herstellung entsprechender Korrosionsschutzpapiere, die Quadratmetergewichte von 15 bis 70 g/qm oder mehr besitzen, haben sich als Bindemittel Polyäthylenimine bzw. Polyacryl- oder -methacrylnitrile bewährt.The work has shown that any in the manufacture of pulp The chemicals required for the wrapping paper must be acid-free and salt-free must and the cellulose used must not contain any oxidative residues. at the production of appropriate anti-corrosive papers, the square meter weights of 15 to 70 g / m² or more have polyethyleneimines as binders or polyacrylonitrile or methacrylonitrile proven.

Als Belegungsmittel für die Korrosion verhindernde Papiere werden wäßrige Lösungen aus Gemischen von Natriumbenzoat und Natriumnitrit oder Guanidincarbonatund1,4-Butendiolnitrit oder aus Natriumbenzoat und 1,4-Butendiolnitrit gleichzeitig oder nachträglich zugesetzt. Hierbei genügen in der Regel für das Einwickeln hochwertiger Metallgegenstände pro Quadratmeter 2 bis 4 g obengenannter Mischungen, wobei die reduzierend wirkenden Verbindungen in geringen Anteilen vorhanden sein müssen. Beispiel 1 Aus einem alkalisch nachgewaschenen Zellstoff wird auf einer Papiermaschine ein 20 g/qm schweres Papier hergestellt. Als Bindemittel werden 1 bis 4 °/o Polyäthylenimin verwendet. Dieses Papier wird anschließend durch einen Jigger geführt, der eine Lösung aus 3 °/o Natriumbenzoat und 1,5 °/o Natriumnitrit enthält. Dann wird auf etwa 100 °/o ausgequetscht und anschließend getrocknet. Beispiel 2 Aus einem alkalisch gekochten, mit salzfreiem Wasser gewaschenen Zellstoff wird auf einer Papiermaschine ein 30 g/qm schweres Papier hergestellt, wozu als Bindemittel wasserlösliches Polyacrylnitril verwendet wird. Dieses Papier erhält eine Beschichtung einer Mischung aus 2"/, Phenylguanidincarbonat und 1,4-Butindiolnitrit, die mit 20/, Polyacrylnitril gebunden ist. Zur Kennzeichnung können verschiedene kationaktive Farbstoffe verwendet werden, so z. B. salzfreies Methylenblau oder Acrydinrot. Nach Bedarf können Füllstoffe und geeignete Weichmacher der Masse zugesetzt werden.As a covering for the corrosion-preventing papers aqueous solutions of mixtures of sodium benzoate and sodium nitrite or guanidine carbonate and 1,4-butenediol nitrite or from sodium benzoate and 1,4-butenediol nitrite added simultaneously or subsequently. As a rule, this is sufficient for wrapping high-quality metal objects Square meter 2 to 4 g of the above-mentioned mixtures, with the reducing effect Connections must be present in small proportions. Example 1 From an alkaline The pulp that has been rewashed becomes a 20 g / m² heavy paper on a paper machine manufactured. 1 to 4% polyethyleneimine is used as a binder. This Paper is then passed through a jigger containing a solution of 3% sodium benzoate and contains 1.5% sodium nitrite. Then it is squeezed out to about 100% and then dried. Example 2 From an alkaline cooked, with salt-free Water-washed pulp is made on a paper machine with a weight of 30 g / m² Paper made using water-soluble polyacrylonitrile as a binder will. This paper is coated with a mixture of 2 "phenylguanidine carbonate and 1,4-butynediol nitrite, bound with 20 /, polyacrylonitrile is. Various cationic dyes can be used for labeling, so z. B. salt-free methylene blue or acrylic red. If necessary, fillers can be added and suitable plasticizers are added to the mass.
