Description
Schnelltrocknende Anstrichstoffe enthalten tiefsiedende Lösemittel mit niedrigem Flammpunkt. In der Regel liegt der Flammpunkt des fertigen Anstrichstoffs sogar noch tiefer als der des darin enthaltenen Lösemiuelgemischs. Der niedrige Flammpunkt solcher Anstrichstoffe erfordert entweder eine drastische Beschränkung der Lagerhaltung oder die Anlage eines Lagers für die Gefahrenklasse AI. Derartige Lager sind sehr teuer.Quick-drying paints contain low-boiling solvents with a low flash point. In the As a rule, the flash point of the finished paint is even lower than that of the one it contains Solvent mixture. The low flash point such Paints require either a drastic inventory restriction or the establishment of one Storage for hazard class AI. Such bearings are very expensive.
Ersetzt man die tiefsiedenden Lösemittel mit niedrigem Flammpunkt wie Isobutylacetat, Methyläthyl-kcton oder Toluol durch solche mit höherem Flammpunkt wie Xylol oder n-Butylacetat, so verlängert sich die Trocknungszeit erheblich. Damit sind bestimmte Lackierungen an senkrechten Flächen ,nur noch bedingt möglich. Bei Fahrbahnmarkierungsfarben wird die Zeit der Verkehrsbehinderung durch Markierungsarbeiten sehr verlängert und bei Markierungsarbeiten auf Schwarzdecken ergeben sich Verfärbungen durch Anlösen der Fahrbahndecke, das ein starkes Bluten verursacht.If you replace the low-boiling solvents with a low flash point such as isobutyl acetate, methylethyl-octone or toluene by those with a higher flash point such as xylene or n-butyl acetate the drying time increases considerably. This means that certain paint jobs are on vertical surfaces, only still possible to a limited extent. In the case of lane marking paints, the time of traffic obstruction is due to marking work very elongated and when marking work on black ceilings, discoloration occurs by dissolving the pavement, causing profuse bleeding.
Ziel der Erfindung war es, lösemittelhaltige Anstrichstoffe zu schaffen, die einen relativ hohen Flammpunkt, insbesondere einen Flammpunkt über 21°C, aufweisen und dennoch rasch trocknen.The aim of the invention was to create solvent-based paints that have a relatively high flash point, in particular have a flash point above 21 ° C and still dry quickly.
Es wurde gefunden, daß man schnelltrocknende, lösemittelhaltige Anstrichstoffe erhält, deren Flammpunkt über 21 °.C liegt, wenn man als Lösemittel Isobutylacetat und/oder Toluol und ggf. Isopropanol und bis zu 35 Gew.-% bezogen auf das Gesamtgewicht der im Anstrichstoff enthaltenen Lösemittel an Trichlortrifluoraethan und/oder Methylenchlorid verwendet.It has been found that quick-drying, solvent-based paints are obtained whose flash point is above 21 ° .C if the solvent is isobutyl acetate and / or toluene and optionally isopropanol and up to 35% by weight based on the total weight of the paint contained in the paint Solvent on trichlorotrifluoroethane and / or methylene chloride used.
Der erfindungsgemäß zuzusetzende Halogenkohlenwasserstoff wirkt dabei in der Regel nur als Verschnittoder Verdünnungsmittel. Echte Lösemittel für die in den Anstrichstoffen enthaltenen Bindemittel kann er nicht ersetzen, ausgenommen Benzin. Jedoch ist der volle Ersatz von Benzin auch nur dann möglich, wenn die durch die besonders rasche Verdunstung des Halogen-Kohlenwasserstoffs bedingte Trocknungsgeschwindigkeit des Anstrichstoffs nicht stört.The halogenated hydrocarbon to be added according to the invention generally only acts as a blend or Diluents. He cannot use real solvents for the binders contained in the paints replace, excluding gasoline. However, full replacement of gasoline is only possible if the Drying speed due to the particularly rapid evaporation of the halogenated hydrocarbon of the paint does not interfere.
Der Gehalt an Halogen-Kohlenwasserstoff kann bis zu etwa 35 Gew.-%, bezogen auf das Gesamtgewicht des Lösemittelgemisches betragen. Höhere Gehalte können, wie auch zu große Mengen an Verschnittmitteln, bewirken, daß die Farbe instabil wird. Prinzipiell können Trichlor-trifluoraethan oder Methylenchlorid alleine oder Gemische dieser Halogen-Kohlenwasserstoffe verwendet werden. Bevorzugt verwendet man im Sinne der Erfindung Trichlorfluoraethan, weil es einerseits die Trocknung nicht über Gebühr beschleu-The halogen hydrocarbon content can be up to about 35% by weight, based on the total weight of the solvent mixture. Higher contents, as well as too large amounts of by-products, can cause the color to become unstable. In principle, trichlorotrifluoroethane or methylene chloride can be used alone or mixtures of these halogenated hydrocarbons can be used. It is preferred to use im Meaning of the invention trichlorofluoroethane, because on the one hand it does not accelerate drying excessively
nigt und zum anderen physiologisch unbedenklich ist.and on the other hand is physiologically harmless.
Methylenchlorid allein kann in solchen Anstrichstoffen Verwendung finden, die extrem rasch trocknen müssen.Methylene chloride alone can be used in paints that dry extremely quickly have to.
Die zur gewünschten Erhöhung des Flammpunktes nötige Menge an Trichlor-trifluoraethan und/oder Methylenchlorid muß im Einzelfall durch einen Vorversuch ermittelt werden.The amount of trichlorotrifluoroethane and / or required for the desired increase in the flash point Methylene chloride must be determined in each individual case by means of a preliminary test.
Die folgenden Beispiele zeigen einige typische Anstrichstoff-Formulierungen:The following examples show some typical paint formulations:

Ersetzt man das Trichlor-trifluoraethan durch Toluol so sinkt der Flammpunkt auf < 200C.If the trichlorotrifluoroethane is replaced by toluene, the flash point drops to <20 ° C.
Ersetzt man das Lösemittelgemisch durch ein schwerer flüchtiges Gemisch aus n-Butylacetat und Xylol, so verlängert sich die Trocknungszeit auf ca. 30 Minuten.If the solvent mixture is replaced by a less volatile mixture of n-butyl acetate and Xylene, the drying time is extended to approx. 30 minutes.
