Beschreibung description
Die vorliegende Erfindung betrifft ein transparentes, flüssiges Imprägniermittel für Holz. Sie betrifft weiterhin ein Verfahren zu dessen Herstellung. The present invention relates to a transparent, liquid impregnating agent for wood. It also relates to a process for its production.
Imprägniermittel für Holz sind bereits bekannt. Sie dienen dazu, das Holz vor schädlichen Umwelteinflüssen zu schützen und seine Lebensdauer zu verlängern. Insbesondere wird ein Schutz gegen den Angriff von Pilzen, Fäulnisbakterien, Algen und Tieren wie Insekten angestrebt. Die Imprägniermittel sind in aller Regel flüssige Systeme, die auch wasserhaltig sein können. Impregnation agents for wood are already known. They serve to protect the wood from harmful environmental influences and to extend its lifespan. In particular, protection against the attack of fungi, putrefactive bacteria, algae and animals such as insects is sought. The impregnating agents are usually liquid systems that can also contain water.
Ein ideales Holzschutzmittel soll nachhaltige Giftwirkung gegen Schädlinge aufweisen, darf jedoch für Menschen und Haustiere nicht giftig sein. Es soll Metalle nicht angreifen, möglichst leicht auch in nicht vorbehandeltes Holz eindringen, darf durch Regen nicht abgewaschen werden und soll möglichst billig sein. An ideal wood preservative should have a sustainable poisoning effect against pests, but must not be toxic to humans and pets. It should not attack metals, penetrate wood that has not been pretreated as easily as possible, must not be washed off by rain and should be as cheap as possible.
Eine grosse Schwierigkeit stellt das Eindringen des Mittels in das Holz dar. Daher wendet man zur Zeit Kesseldruckverfahren an, bei denen das vorgetrocknete Holz in einem verschlossenen, Imprägniermittel enthaltenden Behälter abwechselnd Überdrücken und Unterdrücken ausgesetzt wird. A great difficulty is the penetration of the agent into the wood. For this reason, boiler pressure processes are currently used in which the pre-dried wood is alternately subjected to overpressure and underpressure in a sealed container containing impregnating agent.
Diese Verfahren sind auf fertige Holzgegenstände und insbesondere auf Holzartikel im Bauwesen nicht oder nur sehr kostspielig anwendbar. Die Anstrich verfahren, die auch bereits bekannt sind, haben den Nachteil, dass die Holzgegenstände zuerst mit einem Imprägniermittel grundiert, lange getrocknet und dann mit einem anderen Oberflächenanstrich versehen werden müssen. Dazu kommt, dass das früher als wirksames Imprägniermittel verwendete Carbolineum heute wegen seiner Giftigkeit nicht mehr eingesetzt werden kann. These methods cannot be used or can only be applied very costly to finished wooden objects and in particular to wooden articles in the building industry. The painting methods, which are also known, have the disadvantage that the wooden objects must first be primed with an impregnating agent, dried for a long time and then given another surface coating. In addition, the carbolineum that was previously used as an effective impregnating agent can no longer be used due to its toxicity.
Die oben geschilderte Problematik und die Nachteile der bisherigen Lösungen auf dem Gebiet der Holzimprägnierung und -konservierung sind ausführlich im Römpp'schen Chemie-Lexikon behandelt, z.B. 6. Aufl. 1966, Bd. II, Sp. 2758-2762. The problems described above and the disadvantages of the previous solutions in the field of wood impregnation and preservation are dealt with in detail in the Römpp chemical lexicon, e.g. 6th ed. 1966, vol. II, col. 2758-2762.
Aufgabe der vorliegenden Erfindung war die Schaffung eines insbesondere fungizid und algizid wirksamen wasserfreien Holzimprägnierungsmittels, das im Anstrich aufgebracht werden kann, das besser als bekannte Mittel ins Holz eindringt, aber gleichzeitig als Oberflächenfinish wirkt, d.h. das das Aufbringen eines Oberflächenfirnis, -lackes oder -anstriches unnötig macht. Ausserdem soll das Mittel das Holz besser gegen die Einwirkung von Wasser, UV-Licht, Sonneneinstrahlung und Kälte schützen und dabei umweltverträglich sein, auch was die Herstellung betrifft. The object of the present invention was to provide an in particular fungicidal and algicidally effective water-free wood impregnating agent which can be applied in the paint and which penetrates into the wood better than known agents but at the same time acts as a surface finish, i.e. that makes the application of a surface varnish, varnish or paint unnecessary. In addition, the agent should protect the wood better against the effects of water, UV light, sunshine and cold and be environmentally friendly, also in terms of manufacture.
Das erfindungsgemässe transparente Holzimprägniermittel, das diese Aufgaben erfüllt, ist im unabhängigen Patentanspruch 1 definiert. Besondere Ausgestaltungen bilden den Gegenstand abhängiger Ansprüche. The transparent wood impregnating agent according to the invention, which fulfills these tasks, is defined in independent claim 1. Special configurations form the subject of dependent claims.
Wie weiterhin überraschenderweise gefunden wurde, ist bei der Herstellung die Reihenfolge der Zugabe der Bestandteile des erfindungsgemässen Holzimprägniermittels insofern kritisch, als bei einer bestimmten Reihenfolge die besten Ergebnisse erzielt werden. Daher betrifft die Erfindung weiterhin ein Verfahren zur Herstellung des obigen Holzimprägniermittels, und das Verfahren ist im zweiten unabhängigen Patentanspruch definiert. As was also surprisingly found, the order in which the constituents of the inventive wood impregnating agent are added is critical in that the best results are obtained in a specific order. Therefore, the invention further relates to a method for producing the above wood impregnating agent, and the method is defined in the second independent claim.
Es sollen nun die einzelnen Bestandteile des erfindungsgemässen transparenten Imprägniermittels näher identifiziert werden. The individual components of the transparent impregnating agent according to the invention are now to be identified in more detail.
Hauptbestandteil («Körper») der lösungsmittelfreien Phase des Mittels ist ein chemisch trocknender Stoff auf Leinölbasis, der normalerweise nur zur Verwendung für Oberflächenanstriche bekannt ist. Er-findungsgemäss handelt es sich um ein isocyanatmodifiziertes Leinöl. Besonders geeignet ist das Produkt URADUR F 77, das als 60%ige Lösung in White Spirit von der Fa. DMS Resins geliefert wird. The main component ("body") of the solvent-free phase of the agent is a chemically drying substance based on linseed oil, which is normally only known for use on surface coatings. According to the invention, it is an isocyanate-modified linseed oil. The product URADUR F 77, which is supplied as a 60% solution in white spirit by DMS Resins, is particularly suitable.
Zur besseren Härtung dieses Produktes, das zwar lufttrocknend ist, dessen Härtung aber auch im Innern des Holzes vor sich gehen soll, wohin Luft nicht zutreten kann, werden die an sich bekannten Sik-kative Metallnaphthenate, -octoate, -linoleate, -resinate u.dgl. zugesetzt. Besonders bewährt hat sich eine Mischung aus Mangan-, Calcium- und Zirkonverbindungen, die neu ist und eine überraschend gute und schnelle Trocknung bewirkt. Gut geeignete Sikkative dieser Gruppe, d.h. die Einzelmetallderivate, wurden unter der Handelsbezeichnung Nuodex von der Fa. URAI S.p.a., Assago, Italien, bezogen. For better hardening of this product, which is air-drying, but whose hardening should also take place inside the wood, where air cannot enter, the known sik-kative metal naphthenates, octoates, linoleates, resinates and the like. the like added. A mixture of manganese, calcium and zirconium compounds, which is new and has surprisingly good and quick drying properties, has proven particularly useful. Well-suited siccatives from this group, i.e. the individual metal derivatives were obtained under the trade name Nuodex from URAI S.p.a., Assago, Italy.
Als Lösungsmittel enthält das erfindungsgemässe Holzimprägniermittel - ausser dem White Spirit des modifizierten Leinöls - mit Vorteil nur sauerstoffhaltige aliphatische Verbindungen. Die gewählten Lösungsmittel scheinen für das gute Eindringen des erfindungsgemässen Mittels in das Holz verantwortlich zu sein. Ausserdem sind sie weit umweltverträglicher als Kohlenwasserstoffe. Es hat sich ein Gemisch aus einem niederen Glykolether vom Siedepunkt zwischen 100 und 150°C mit einem Esteralkohol vom Siedepunkt 180 bis 260°C bewährt. Solche Glykolether sind z.B. Dowanol PM der Dow Chemical Company (Propylenglykolmonomethylether) sowie Ethylenglykolmethylether und Ethylenglycolethyl-ether, insbesondere aber Butyldiglykolether («Butylcarbitol»). Esteralkohole sind z.B. Glykolmonofor-miat und -acetat. Bewährt hat sich das Produkt TEXANOL der Eastman Chemical Company. As a solvent, the wood impregnating agent according to the invention - apart from the white spirit of the modified linseed oil - advantageously only contains oxygen-containing aliphatic compounds. The solvents chosen seem to be responsible for the good penetration of the agent according to the invention into the wood. They are also far more environmentally friendly than hydrocarbons. A mixture of a low glycol ether with a boiling point between 100 and 150 ° C and an ester alcohol with a boiling point between 180 and 260 ° C has proven itself. Such glycol ethers are e.g. Dowanol PM from the Dow Chemical Company (propylene glycol monomethyl ether) and ethylene glycol methyl ether and ethylene glycol ethyl ether, but especially butyl diglycol ether ("butyl carbitol"). Ester alcohols are e.g. Glycol monoformate and acetate. The product TEXANOL from the Eastman Chemical Company has proven itself.
Als bioziden Stoff enthält das erfindungsgemässe Holzimprägniermittel bevorzugt ein Sulfamidderi-vat, das gegen Pilze, Algen, Penicilliumarten wirksam ist, lichtstabil und nichtflüchtig ist und die Trocknung des Leinölderivats nicht stört. Bevorzugt verwendet man ein N,N-DiaryI-N'-aryl-N'(trihalogenmethyl)-sulfamid. As a biocidal substance, the wood impregnating agent according to the invention preferably contains a sulfamide derivative which is active against fungi, algae, penicillium species, is light-stable and non-volatile and does not interfere with the drying of the linseed oil derivative. An N, N-diaryl-N'-aryl-N '(trihalomethyl) sulfamide is preferably used.
Das erfindungsgemässe Holzimprägniermittel enthält in der Regel, aber nicht zwingend, ein Verlaufmittel, z.B. Aldoxime oder Ketoxime. Geeignete Oxime sind z.B. Butyraldoxim, Methylethylketoxim und Cy- The wood impregnating agent according to the invention generally, but not necessarily, contains a leveling agent, e.g. Aldoximes or ketoximes.

clohexanonoxim. Weitere geeignete Zusätze sind Theologische Additive wie z.B. organisch modifizierte Schichtsilikate («Bentone SD-1» der Kronos Titan GmbH, Leverkusen, BRD) sowie sonstige übliche Zusatzstoffe wie Netz- und Dispergier mittel, Aromastoffe etc. clohexanone oxime. Other suitable additives are theological additives such as organically modified layered silicates (“Bentone SD-1” from Kronos Titan GmbH, Leverkusen, Germany) as well as other usual additives such as wetting and dispersing agents, flavorings etc.
Die Zusammensetzung besonders geeigneter Holzimprägniermittel ist die folgende, angegeben in Gewichtsteilen: The composition of particularly suitable wood impregnating agents is the following, given in parts by weight:
Isocyanatmodifiziertes Leinöl, 60% in White Spirit Isocyanate modified linseed oil, 60% in white spirit
25 bis 35 25 to 35
Sikkativgemisch Oßweils auf das Metall bezogen): Desiccant mixture based on the metal):
0,04 bis 0,12 0.04 to 0.12
Biozid: Biocide:
0,5 bis 1,2 0.5 to 1.2
Lösungsmittel, Etherund Esteralkohole davon 1 bis 5 Teile Solvents, ethers and ester alcohols thereof 1 to 5 parts
55 bis 75 55 to 75
Glykolether, Rest Esteralkohole Glycol ethers, the rest ester alcohols
Dazu kommt, wenn gewünscht, Hautverhinderungsmittel In addition, if desired, skin prevention agents
0,3 bis 0,8 0.3 to 0.8
Zur Ausführung des erfindungsgemässen Verfahrens legt man zunächst das Lösungsmittel in einem Rührgefäss vor, lässt die Lösung des modifizierten Leinöls zulaufen und gibt die Sikkative und das Biozid zu. Von den wahlweisen Zusatzstoffen wird der Hautverhinderer gleich nach den Sikkativen zugesetzt. Selbstverständlich wird bei der Herstellung ständig gerührt. Man arbeitet am besten bei normaler Zimmertemperatur; ein Ansatz von ca. 100 kg ist in etwa 20 bis 30 Minuten fertiggestellt. To carry out the process according to the invention, the solvent is first placed in a stirred vessel, the modified linseed oil solution is run in and the siccative and the biocide are added. Of the optional additives, the skin inhibitor is added immediately after the desiccants. Of course, there is constant stirring during manufacture. It is best to work at normal room temperature; a batch of approx. 100 kg is completed in about 20 to 30 minutes.
Das Imprägniermittel zeichnet sich noch durch erhöhte Lagerfähigkeit aus, im allgemeinen ca. 8 bis 12 Monate. The impregnating agent is also characterized by an increased shelf life, generally about 8 to 12 months.
Zur Anwendung bestreicht oder besprüht man die mechanisch gereinigte Holzoberfläche mit dem flüssigen Mittel, lässt z.B. 24 Std. trocknen und versieht die Oberfläche mit einem zweiten Anstrich desselben Mittels. Nur selten ist ein dritter Anstrich erforderlich. Das Holz ist jetzt konservierend imprägniert und besitzt ausserdem seine Naturfarbe, z.B. Nussbaum, Lärche, Mahagoni, Teak usw., ohne dass ein weiterer, unterschiedlicher Anstrich wie Beize o.dgl. nötig wäre. For use, brush or spray the mechanically cleaned wooden surface with the liquid agent, e.g. Dry for 24 hours and apply a second coat of the same agent to the surface. A third coat is rarely required. The wood is now impregnated with a preservative and also has its natural color, e.g. Walnut, larch, mahogany, teak etc. without another, different coating such as stain or the like. would be necessary.
Ein Beispiel soll die Erfindung weiter erläutern. An example is intended to explain the invention further.
Beispiel example
In einen mit Entlüftung nach aussen versehenen Rührkessel mit einem Nutzinhalt von etwa 150 I bringt man 3 kg Dowanol PM (Propylenglykolmethylether, Kp. 120°C) und 64,5 kg TEXANOL (Esteralkohol, Kp. 244°C). Unter Rühren fügt man nach und nach folgende Produkte zu: 30 kg URADUR F-77 (60% in White Spirit), 0,2 kg Mangansikkativ (6% Mn), 0,6 kg Calciumsikkativ (4% Ca), 0,4 kg Zirkoniumsikkativ (12% Zr), 0,5 kg EXKIN 2 (Methylethylketoxim) und 0,8 kg Biozid. Nach 30minütigem Rühren erhält man ein transparentes Imprägniermittel mit den oben beschriebenen Eigenschaften, das in Holz sehr gut eindringt. 3 kg of Dowanol PM (propylene glycol methyl ether, bp. 120 ° C) and 64.5 kg of TEXANOL (ester alcohol, bp. 244 ° C) are placed in a stirred kettle with ventilation to the outside with a useful capacity of approx. 150 l. The following products are gradually added with stirring: 30 kg of URADUR F-77 (60% in White Spirit), 0.2 kg of manganese siccative (6% Mn), 0.6 kg of calcium siccative (4% Ca), 0.4 kg of zirconium silicate (12% Zr), 0.5 kg of EXKIN 2 (methyl ethyl ketoxime) and 0.8 kg of biocide. After stirring for 30 minutes, a transparent impregnating agent with the properties described above is obtained, which penetrates very well into wood.
Wie schon erwähnt wurde, ist eine weitere Oberflächenbehandlung des imprägnierten Holzes unnötig, kann jedoch, wenn gewünscht, vorgenommen werden. Die beschriebene Imprägnierung stört nachträgliche anders- oder gleichartige Anstriche oder Überzüge nicht. As already mentioned, further surface treatment of the impregnated wood is unnecessary, but can be carried out if desired. The impregnation described does not interfere with subsequent different or similar coatings or coatings.
