Description

Verfahren zur Oberflächenbehandlung von in Holz gefaßten Schreib- oder Zeichenstiften Die Erfindung betrifft eine weitere Ausbildung des Verfahrens nach Patent 726617 zur Oberflächenbehandlung von holzgefaßten Schreib- oder Zeichenstiften.Method for the surface treatment of writing or drawing pens mounted in wood The invention relates to a further development of the method according to patent 726617 for the surface treatment of wood-mounted writing or drawing pens.

Nach der älteren Erfindung werden die in Holz gefaßten Schreib- oder Zeichenstifte nach dem Durchzugsverfahren mit einem Lackfilm versehen unter Verwendung eines Bades von monomeren, bei gewöhnlichen Temperaturen flüssigen Verbindungen, die sich leicht polymerisieren lassen, wie z. B. Styrol. Dabei tritt die monomere Verbindung, z. B. Äthylenderivat, an die Stelle der flüchtigen organischen Lösungsmittel, die früher benutzt wurden, und ersetzt diese.According to the older invention, the writing or written in wood Applying a lacquer film to drawing pens using the drawing method a bath of monomeric compounds that are liquid at ordinary temperatures, which can be easily polymerized, such as. B. styrene. The monomer occurs Connection, e.g. B. ethylene derivative, instead of volatile organic solvents, that were previously used and replaces them.

Gemäß vorliegender Erfindung werden die monomeren Polymerisationsstoffe den gebräuchlichen Politurlacken, welche flüchtige organische Lösungsmittel enthalten, zugesetzt. Die Polymerisation der monomeren Verbindung findet in dem durch den Auftrag gebildeten Film statt; sie wird, wie sich unerwarteterweise herausgestellt hat, durch di;e Verflüchtigung der organischen Lösungsmittel nicht gestört.According to the present invention, the monomeric polymerization substances the common polish lacquers, which contain volatile organic solvents, added. The polymerization of the monomeric compound takes place in the by order educated film place; as it turned out unexpectedly, not disturbed by the volatilization of the organic solvents.

Durch die Erfindung werden folgende Vorteile erzielt: Man kann mehr Farbstoff als bisher zugeben, so daß der Politurlack höhere Deckkraft erhält. Durch den Polymerisationsvorgang wird der Zusatz von monomerem Äthylenderivat zum Bindemittel für die Farbstoffe. Ein Teil der flüssigen Phase des Lackes geht nicht flüchtig, sondern erhärtet bei der Polymerisation. Daher kann man stärkere Schichten auftragen, um einen kräftigeren Sitin.-zu bilden.The invention achieves the following advantages: You can do more Add dye than before so that the polish has a higher covering power. By The polymerization process is the addition of monomeric ethylene derivative to the binder for the dyes. Part of the liquid phase of the paint is not volatile, but hardened during polymerization. Therefore you can get stronger Apply layers to form a thicker sitin.

Bei der Ausführung der Erfindung wird beispielsweise folgendermaßen verfahren: Man verwendet einen zum Polieren von holzverschalten Schreib- oder Zeichenstiften üblichen Lack von der Zusammensetzung iß Teile Nitrocellulose, - Polyvinylacetat, q. - Dibuthylphtalat, qo - einer Mischung aus Methyl- und Äthylacetat, 6 - Milchsäurebut_ylester_, 25 - Farbstoff. Diesem Lack, der gewissermaßen die Grundpolitur darstellt, werden gemäß der Erfindung 3o Teile monomeres Äthylenderivat zugegeben. Zugleich kann man den Farbstoffgehalt um 3o Teile erhöhen. Der angegebene Politurlack erhält also einen. Zusatz von 3o Teilen Monomethacrylsäuremethy lester und 3o Teilen Farbstoff.In carrying out the invention, the following procedure is used, for example: A lacquer of the composition that is customary for polishing wood-clad writing or drawing pens is used eat parts of nitrocellulose, - polyvinyl acetate, q. - dibutyl phthalate, qo - a mixture of methyl and Ethyl acetate, 6 - lactic acid butyl ester, 25 - dye. According to the invention, 30 parts of monomeric ethylene derivative are added to this lacquer, which in a sense represents the basic polish. At the same time the dye content can be increased by 30 parts. The specified polish thus receives a. Addition of 3o parts of methyl monomethacrylate and 3o parts of dye.

Die Polymerisation der monomeren Verbindung findet nicht bereits in der Lackflüssigkeit, sondern erst in dem durch den Auftrag gebildeten Film statt; sie kann durch Wärme, ultraviolettes Licht oder Hinzufügung eines Katalysators beeinfiußt (beschleunigt) werden. Durch das Flüchtiggehen des organischen Lösungsmittels wird der Polymerisationsvurgang nicht beeinträchtigt.The polymerization of the monomeric compound does not already take place in the paint liquid, but only in the film formed by the application; it can be influenced by heat, ultraviolet light or the addition of a catalyst (accelerated). Due to the volatility of the organic solvent the process of polymerization is not impaired.
