Description
Verfahren zur Erhöhung der Lichtbeständigkeit von geformten Polyamiden Eine große Anzahl organischer Substanzen zur Erhöhung der Lichtbeständigkeit von Kunststoffen ist bekannt. Diese werden entweder dem Kunststoff vor oder nach der Verformung einverleibt. Es handelt sich bei diesen Lichtschutzmitteln meistens um Verbindungen, die ultraviolette Strahlen absorbieren.Process for increasing the lightfastness of molded polyamides A large number of organic substances to increase the light resistance of Plastics is known. These are either before or after the plastic Deformation incorporated. These sunscreens are mostly Compounds that absorb ultraviolet rays.
Einzelne Substanzen besitzen jedoch auch Schutzwirkung, ohne daß sie ultraviolette Strahlen absorbieren.However, individual substances also have protective effects without them absorb ultraviolet rays.
Die meisten der bekannten Lichtschutzmittel zeigen jedoch den Nachteil, daß sie schon nach wenigen Wäschen aus den geformten Gebilden, wie Fasern und Fäden, so weit herausgewaschen werden, daß die Lichtschutzwirkung verlorengeht. Most of the known light stabilizers, however, have the disadvantage that after just a few washes they leave the formed structures, such as fibers and threads, be washed out so far that the light protection effect is lost.
Gegenstand der vorliegenden Erfindung ist ein Verfahren zur Erhöhung der Lichtbeständigkeit von geformten Polyamiden, dadurch gekennzeichnet, daß als Lichtschutzmittel substituierte Triazine verwendet werden, die mit demPolyamid chemische Bindungen eingehen und als Substituenten organische Reste mitLichtschutzwirkung enthalten, z. B. auf Grundlage von Polyoxybenzophenonen, Benztriazolen bzw. Benzoxazolen. The present invention relates to a method for increasing the light resistance of molded polyamides, characterized in that as Light stabilizers substituted triazines are used, which chemical with the polyamide Form bonds and, as substituents, organic radicals with a photoprotective effect included, e.g. B. based on polyoxybenzophenones, benzotriazoles or benzoxazoles.
Läßt man Verbindungen dieser Art auf Polyamidfasern und-faden oder-gewebe oder-gewirke einwirken, gegebenenfalls unter Zusatz entsprechender Mengen organischer oder anorganischer Basen zum Abfangen des frei werdenden Halogenwasserstoffes, so wird das Lichtschutzmittel ohne praktische Einbuße in seiner Wirksamkeit an das Polyamid gebunden. One leaves connections of this kind on polyamide fibers and threads or fabrics or knitted fabrics act, if necessary with the addition of appropriate amounts of organic or inorganic bases to trap the liberated hydrogen halide, see above the light stabilizer is effective against the Polyamide bonded.
Es ist an sich bekannt, daß ein Teil der sogenannten » Reaktivfarbstoffe « in der Weise hergestellt wird, das an den Farbstoff durch Umsetzung mit Cyanurchlorid ein Triazinring mit mindestens einem noch aktiven Halogenatom gekoppelt wird. Die so umgesetzten Farbstoffe werden beim Färbevorgang an die Fasergrundlage chemisch gebunden. Es war jedoch nicht vorauszusehen, daß eine Verknüpfung von als Lichtschutzmittel in Frage kommenden organischen Verbindungen mit Cyanurchlorid fast keine Einwirkung auf dieAbsorptionskurve eines Ultraviolett absorbierenden Stoffes hat, selbst dann nicht, wenn man das aus der Umsetzung resultierende Produkt unter Halogenwasserstoffabspaltung an einen Fasergrundstoff bindet. It is known per se that some of the so-called »reactive dyes «In the way that the dye is produced by reacting it with cyanuric chloride a triazine ring is coupled with at least one still active halogen atom. the Dyes converted in this way are chemically applied to the fiber base during the dyeing process bound. However, it was not foreseeable that a combination of as a light stabilizer organic compounds with cyanuric chloride in question have almost no effect on the absorption curve of an ultraviolet absorbent, even then not if the product resulting from the reaction is split off with elimination of hydrogen halide binds to a fiber base.
Die sehr viel größere Waschbeständigkeit von reaktionsfähigen Lichtschutzmitteln gegenüber den entsprechenden, gleichfalls als Lichtschutzmittel angewendeten Ausgangssubstanzen zeigt das folgende Beispiel. The much greater resistance to washing of reactive sunscreens compared to the corresponding starting substances, which are also used as light stabilizers shows the following example.
Herstellung des als Ausgangsstoff dienenden Lichtschutzmittels Äquivalente Mengen 2,4-Dioxybenzophenon und Cyanurchlorid werden in Eiswasser in Gegenwart einer äquivalenten Menge Natriumhydroxyd zur Reaktion gebracht ; das 2,4-Dichlor-6- (3-oxy-4-benzoyl-phenoxy)-triazin fällt als farblose Substanz aus. Production of the light stabilizer used as the starting material equivalents Amounts of 2,4-dioxybenzophenone and cyanuric chloride are present in ice water one equivalent amount of sodium hydroxide reacted; 2,4-dichloro-6- (3-oxy-4-benzoyl-phenoxy) -triazine precipitates as a colorless substance.
Mit ihm werden folgende Versuche durchgeführt : 200-m-Faden aus Polyhexamethylenadipamid mit 2°/o Titanoxydzusatz, Stärke 40 den, 13 Fibrillen, wird in einer Lösung von 1,69 g 2,4-Dichlor-6- (3-oxy-4-benzoyl-phenoxy)-triazin und 0,8 g Pyridin in 20Q ml Aceton 3 Stunden zum Rückfluß erhitzt, die Fasern mit Wasser kurz gespült und bei 100°C getrocknet. The following tests are carried out with it: 200 m thread made of polyhexamethylene adipamide with 2% added titanium oxide, thickness 40 denier, 13 fibrils, is dissolved in a solution of 1.69 g of 2,4-dichloro-6- (3-oxy-4-benzoyl-phenoxy) -triazine and 0.8 g of pyridine in 20Q ml of acetone heated to reflux for 3 hours, the fibers rinsed briefly with water and dried at 100 ° C.
Der Gehalt an wirksamer Substanz (2,4-Dioxybenzophenon) wird photometrisch in konzentrierter Schwefelsäure bestimmt.The content of the active substance (2,4-dioxybenzophenone) is photometric determined in concentrated sulfuric acid.
Die nachfolgende Tabelle gibt die gefundenen Werte vor und nach einer bis drei Wäschen wieder im Vergleich zu dem Gehalt, den man findet, wenn das gleiche Material unter den gleichen Bedingungen mit unsubstituiertem 2,4-Dioxy-benzophenon behandelt wird. The following table shows the values found before and after a up to three washes again compared to the salary one finds if the same Material under the same conditions with unsubstituted 2,4-dioxy-benzophenone is treated.
