Description
Verfahren zur Herstellung von gefärbten, Zellulosederivate enthaltenden Streichlacken. Im Hauptpatent ist .ein, Verfahren zur Herstellung von gefärbten, Zellulo,sederiivate enthaltenden @Streiohla,aken ibeeehrieben, bei dem man idie nach d.eim Verfahren des Schweizer Patentes Nr. 1137d-1 erhältlichen, gefärbten Massen in Alkyläthern von Gly kolen löst.
Es wurde nun ,gefunden, @dass man: oben falls wertvolle gefärbte, Zellu:los-ederiviate enthaltende iStreichla.cke erhält, wenn Iman die nach dem Verfahren des Patentes Nr.137401 erhältlichen, gefärbten Massen aus Zellulosed@erivaten in Alkyläthern von Glykolen löst.
Man kann hierfür sowohl die 1Vlonoalkyl-, als auch die Dialkyläther von -Glyk.olen, wie Äthylen,glykolmonoäthyläther, Propylenglyko,ld.imethyläther usw., verwen den, und .es können auch veresterte Mano- a.lkyläther ider Glykole zur Anwendung ge langen.
Auch Gemische dieser Äther und Ester miteinander und mit andern .Stoffen sind gut geeignet. Man kann, auf die an gegebene Weise Setreiahlaoke erhalten, .die beim Trocknen der Lackanstriche ohne wei tere Nachbehandlung hoch,glänzenide, gleich mässige Überzüge liefern.
iSo hergestellte Lacke lassen sich imit aromatischen Kohlen wass-erstoffen und deren Halogenderivaten und ferner mit aliphatischen und hydro-aro- matischen Alkoholen, sowie mit Mischungen dieser Stoffe verdünnen, ohne die wertvolle Eigenschaft, hoahglänzenide Lackanstriche zu geben, zu verlieren.
Insbesondere bei Ver wendung von Nitrozellulose enthaltenden Massen kann man, wie Versuche ergaben, von den genannten Verdünnungsmitteln sehr grosse Mengen zusetzen und so den Gehalt an Glykold.erivaten herabdrücken; beispielsweise kann man bei Verwendung einer niedrig viskosen Nitrozellulose un<B>d</B> von technisch ab solutem Alkohol uls Verdünnungsmittel Lacke Jierstellen, idie nur etwa 1,2 bis 15 Glykolderivat enthalten.
Zur Erzielung von Lackanstrichen, die nicht nur hochglänzend, sondern gleichzeitig auch völlig glatt auftrocknen, ist es zweck- mässig, den Lösungen der genannten gefärb ten Massen in Glykoläthern und deren De rivaten Benzol und Halogenderivate von Ben- zolkohlenwasserstoffen zuzusetzen. Bei Ver wendung der letzteren können daneben auch aromatische Köhlenwasserstoffe,
sowie hoch siedende und langsam verdunstende Stoffe, wie Tetrahydronaphtalin, Terpentinöl und dergleichen in geeigneten Mengen zugefügt werden, ohne :dass beim Trocknen Trübungen oder Unebenheiten entstehen.
-So erhaltene Lacke lassen sich leicht, zum Beispiel mit einem Pinsel, auf feste Unter- laben, wie Glas, Metall!blech.e, Spachtel massen und ähnliche -Grundierungen, 01 flarben etc. aufstreichen, besitzen lautes Deck vermögen, trocknen hoe;hglän:zend und hart ,auf und zeigen eine vorzügliche Tiefenwir kung und Brillanz ides Farbtones.
Bei :ge eigneter .Auswahl der .Streckungs@mittel be sitzen die Lacke ausserdem einen äusserst schwaohen :Geruch, so dass sie sich auch .für Innenanstriche verwenden lassen.
Die erwähnten vorteilhaften Eigenschaf- ten gemäss dem vorliegenden Verfahren .er hältlicher Lacke bleiben auch dann erhalten, wie Versuche gezeigt halben, wenn man weitere Zellulosederivate, Harze, Weich- machungsmittel, Kampfer, in,den angewand ten Lösungsmitteln lösliche Farbstoffe, an d:
ere Lösungsmittel usw.zufügt.
Beispiel: 40 Teile einer mit geringer Viskosität löslichen Nitrozellulose (10,8/o Stickstoff) werden mit 20 Teilen Dllbutylphtalat und 80 Teilen Lithol.echtscharlach B (Schultz, 1'.arbstofftabellen., 6. Auflage,<B>S.,32,</B> Nr. 73) auf einem Walzenpaar :zehnmal .dünn aus gewalzt.
Man löst die so gewonnene Masse unter Zugabe von 160 Teilen einer mit ge ringer Viskosität löslichen Nitrozellulose (10,8% Stickstoff), 6 Teilen Dibutylphtal-at und 4 Teilen eines spritlöslichen Harzes in einer Mischung aus 150 Teilen Glykolmono- äthyläther und 450 Teilen absolutem Al kohol auf. Man erhält einen geruchschwachen Streichlack, der harte, hochglänzende An striche liefert.
Process for the production of colored coating varnishes containing cellulose derivatives. The main patent is a process for the production of colored, cellulosic derivatives containing @ Streiohla, aken ibeeehrieben, in which one dissolves the colored masses obtainable by the method of Swiss patent No. 1137d-1 in alkyl ethers of glycols.
It has now been found that if Iman dissolves the colored masses of cellulose derivatives in alkyl ethers of glycols, which can be obtained by the process of patent no. 137401, from above, valuable colored, cellulose-ederiviate-containing strokes are obtained .
For this purpose, both the monoalkyl and dialkyl ethers of glycols, such as ethylene, glycol monoethyl ether, propylene glycol, dimethyl ether, etc., can be used, and esterified mano-alkyl ethers or glycols can also be used long.
Mixtures of these ethers and esters with one another and with other substances are also suitable. Setreiahlaoke can be obtained in the manner given, which deliver high, glossy, uniform coatings when the paint coatings dry without further aftertreatment.
Paints produced in this way can be thinned with aromatic hydrocarbons and their halogen derivatives and also with aliphatic and hydro-aromatic alcohols, as well as with mixtures of these substances, without losing the valuable property of giving high-gloss paint coatings.
In particular when using compositions containing nitrocellulose, as tests have shown, very large amounts of the diluents mentioned can be added and thus the content of Glykold.erivaten lower; For example, when using a low-viscosity nitrocellulose and technically absolute alcohol and a diluent, lacquers can be used which contain only about 1.2 to 15 glycol derivatives.
To achieve paint coats that dry not only with a high gloss, but also completely smooth at the same time, it is advisable to add benzene and halogen derivatives of benzene hydrocarbons to the solutions of the stated colored compositions in glycol ethers and their derivatives. When using the latter, aromatic hydrocarbons,
as well as high-boiling and slowly evaporating substances, such as tetrahydronaphthalene, turpentine oil and the like, can be added in suitable amounts without: clouding or unevenness occurring during drying.
Paints obtained in this way can easily be applied, for example with a brush, to solid surfaces such as glass, metal, sheet metal, fillers and similar primers, paints, etc., have noisy coverage, dry hoe; Shiny and hard, open and show an excellent depth effect and brilliance of the same color.
With a suitable .selection of .stretching agents, the paints also have an extremely black odor, so that they can also be used for interior coatings.
The above-mentioned advantageous properties according to the present process .er available paints are retained, as shown in experiments, if further cellulose derivatives, resins, plasticizers, camphor, dyes soluble in the solvents used, are added to:
more solvent, etc.
Example: 40 parts of a nitrocellulose (10.8 / o nitrogen) soluble with low viscosity are mixed with 20 parts of butyl phthalate and 80 parts of Lithol.echtscharlach B (Schultz, 1'.arbstofftabellen., 6th edition, <B> S., 32 , </B> No. 73) on a pair of rollers: rolled thinly ten times.
The mass thus obtained is dissolved with the addition of 160 parts of a nitrocellulose (10.8% nitrogen), 6 parts of dibutylphthalate and 4 parts of a fuel-soluble resin in a mixture of 150 parts of glycol monoethyl ether and 450 parts of absolute Alcohol up. A coating with a weak odor is obtained which delivers hard, high-gloss coatings.
