Abstract
Description
Häufig wird als Holzschutzmittel Karbolineum eingesetzt. Karbolineum fällt bei der Destillation von Steinkohle an und stellt ein komplexes Gemisch aromatischer Kohlenwasserstoffe dar. Häufig wird Karbolineum noch mit leicht flüchtigen aromatischen Kohlenwasserstoffen, wie z. B. Xylol gestreckt. Die eigentliche Holzschutzwirkung wird da bei durch das in Karbolineum enthaltene Steinkohlen-Teeröl-Gemisch erzeugt, während die leicht flüchtigen aromatischen Kohlenwasserstoffe durch Emission an die Umwelt abgegeben werden. Auch wenn es mittlerweile gelungen ist, das als gesundheitsschädlich verdächtigte Benzo(a)pyren weitestgehend aus dem Karbolineum zu entfernen (bis auf Anteile, die kleiner als 0,005% betragen), bleibt nach wie vor die typische Geruchsbelästigung eines gebrauchsfertigen Karbolineums bestehen.Carbolineum is often used as a wood preservative. Carbolineum occurs during the distillation of hard coal and represents a complex one Mixture of aromatic hydrocarbons. Carbolineum is common still with volatile aromatic hydrocarbons, such as e.g. B. stretched xylene. The actual wood protection effect is there in due to the coal-tar oil mixture contained in carbolineum generated while the volatile aromatic hydrocarbons be released into the environment through emissions. Even if it has now succeeded in suspecting it to be harmful to health Remove benzo (a) pyrene as much as possible from the carbolineum (up to on shares smaller than 0.005%) remains the typical smell of a ready-to-use carbolineum consist.
Aus diesen Gründen, namentlich aus dem Bestreben, Lösungsmittel- Emissionen in die Umwelt zu vermeiden, werden, besonders im nicht industriellen Bereich, heute in wassergelöste Holzanstriche bzw. Holz schutzmittel bevorzugt. Hierbei müssen jedoch andere Holzschutzwirk stoffe eingesetzt werden, welche die typische Penetrationsfähigkeit, Kriechfähigkeit und Dauerhaftigkeit des Steinkohlen-Teeröls nicht be sitzen oder aber nicht zu vergleichbar wirtschaftlichen Stoffen zu zählen sind.For these reasons, especially from the desire to use solvent Avoiding emissions to the environment, especially in the industrial area, today in water-soluble wood coatings or wood preferred means of protection. However, other wood preservatives have to be used substances are used, which have the typical penetration ability, Creep and durability of the coal tar oil are not sit or not too comparable economic substances are counting.
Der Erfindung liegt die Aufgabe zugrunde, ein Holzschutzmittel zu schaffen, welches die bisherigen Vorteile des Steinkohlen-Teeröls in vollem Umfang erhält, darüber hinaus jedoch besonders umweltfreund lich und ohne Geruchsbelästigung ist. The invention has for its object to a wood preservative create, which the previous advantages of the coal tar oil in fully, but also particularly environmentally friendly Lich and without nuisance.
Diese Aufgabe löst die Erfindung durch die Verwendung einer Mischung
aus
1 bis 99 Gew.-%, vorzugsweise 50 Gew.-%, Steinkohlen-Teeröl,
1 bis 99 Gew.-%, vorzugsweise 46,9 Gew.-%, Wasser,
0,1 bis 10 Gew.-%, vorzugsweise 1,0 Gew.-% eines Emulgators,
0,1 bis 5 Gew.-%, vorzugsweise 2,0 Gew.-% eines Stabilisators und
0,01 bis 2 Gew.-%, vorzugsweise 0,1 Gew.-% eines Entschäumers
als wasseremulgiertes Holzschutzmittel. - Die Erfindung geht von der
Erkenntnis aus, daß zur Erzeugung eines Holzschutzmittels auf der
Basis von Steinkohlen-Teeröl Emulsionen nach dem Öl-in-Wasser-Prinzip
möglich sind. Es hat sich herausgestellt, daß solche Emulsionen mit
einfachen Rührmaschinen herstellbar sind und überraschenderweise
stabil bleiben, und zwar selbst bei Verwendung von gewöhnlichem
Leitungswasser. Ferner muß überraschen, daß die so hergestellten
Emulsionen auch bei mehreren Frost/Tau-Wechseln durch Schütteln oder
Umrühren unverändert bleiben.The invention achieves this object by using a mixture
1 to 99% by weight, preferably 50% by weight, coal tar oil,
1 to 99% by weight, preferably 46.9% by weight, water,
0.1 to 10% by weight, preferably 1.0% by weight of an emulsifier,
0.1 to 5 wt .-%, preferably 2.0 wt .-% of a stabilizer and
0.01 to 2 wt .-%, preferably 0.1 wt .-% of a defoamer
as a water-emulsified wood preservative. - The invention is based on the knowledge that emulsions according to the oil-in-water principle are possible for producing a wood preservative based on coal tar oil. It has been found that such emulsions can be prepared with simple stirring machines and surprisingly remain stable, even when using ordinary tap water. It must also be surprising that the emulsions produced in this way remain unchanged even with several freeze / thaw changes by shaking or stirring.
Weitere erfindungswesentliche Merkmale sind im folgenden aufgeführt. So besteht der Emulgator erfindungsgemäß aus einer Mischung von N-Alkylbenzolsulfonat, Carbonsäurepolyglykolester und Alkylpolyglykol ether, wobei das Mischungsverhältnis dieser drei unverzichtbaren Be standteile variabel ist. Von Bedeutung ist die Tatsache, daß keine Mischung des Emulgators ohne den jeweils dritten Bestandteil aus kommt. Als Stabilisator kann ein handelsüblicher Stabilisator Verwen dung finden, z. B. ein Polyacrylsäure-Derivat eingesetzt werden. Auch als Entschäumer kommen handelsübliche Entschäumer in Frage, z. B. kann ein Silicon enthaltendes Produkt Verwendung finden. Further features essential to the invention are listed below. According to the invention, the emulsifier consists of a mixture of N-alkyl benzene sulfonate, carboxylic acid polyglycol ester and alkyl polyglycol ether, the mixing ratio of these three indispensable Be components is variable. What is important is the fact that none Mix the emulsifier without the third component is coming. A commercially available stabilizer can be used as a stabilizer find dung, e.g. B. a polyacrylic acid derivative can be used. Also commercially available defoamers are suitable as defoamers, e.g. B. a product containing silicone can be used.
Die durch die Erfindung erreichten Vorteile sind im wesentlichen darin zu sehen, daß ein wasseremulgierbares Holzschutzmittel verwirklicht wird, bei welchem nicht nur die Lösemittel-Behandlung der Umwelt drastisch reduziert wird, sondern ferner der charakteristische und störende Geruch des Steinkohlen-Teeröls kaum noch wahrnehmbar ist, weil - wie bei einer Emulsion - das Bindemittel durch Wasser umhüllt ist. Tatsächlich ist das erfindungsgemäße Holzschutzmittel gleicher maßen wirtschaftlich und umweltfreundlich, wobei die bisherigen Vor teile des Steinkohle-Teeröls als Holzschutzmittel die Penetrationsfähig keit, Kriechfähigkeit und Dauerhaftigkeit in vollem Umfang erhalten bleiben.The advantages achieved by the invention are essentially therein to see that a water emulsifiable wood preservative is realized where not only the solvent treatment of the environment is drastically reduced, but also the characteristic and annoying smell of coal tar oil is hardly noticeable, because - like an emulsion - the binder is covered by water is. In fact, the wood preservative according to the invention is the same moderately economical and environmentally friendly, with previous previous Parts of the coal tar oil as a wood preservative are capable of penetration Preserve full strength, creep ability and durability stay.
