Description

Verfahren zum Färben von Asbest Es wurde gefunden, daß man Asbest sehr vorteilhaft färben kann, wenn man ihn mit Küpen- oder Entwicklungsfarbstoffen in an sich bekannter Weise färbt. Der gefärbte Asbest kann z. B. zur Herstellung durchgefärbter Asbestplatten, -gewebe und -dichtungen oder zur Herstellung besonderer farbiger Effekte in Verbindung mit andersfarbigen Materialien anorganischer oder organischer Natur, z. B. Zement, Wolle u. dgl., Verwendung finden. Durch Nachbehandeln mit Paraffinöl, geschmolzenem Paraffin oder Wachs kann der so gefärbte Asbest hinsichtlich der Farbwirkung für bestimmte Zwecke, z. B. zur Herstellung von gefärbten Asbest-Zement-Platten, noch verbessert werden.Method of dyeing asbestos It has been found that asbestos can be used can be colored very advantageously if you use vat or developing dyes colors in a manner known per se. The colored asbestos can e.g. B. for production solid-colored asbestos sheets, fabrics and seals or for the production of special ones colored effects in connection with other colored materials of inorganic or organic nature, e.g. B. cement, wool and the like., Use. By post-treatment with paraffin oil, molten paraffin or wax, the asbestos thus colored can be treated with regard to the color effect for certain purposes, e.g. B. for the production of colored asbestos-cement panels, still to be improved.

Beispiel i Man schlämmt ioTeile eines Küpenfarbstoffs in 2ooo Teilen Wasser an und bringt ihn sodann-durch Zusatz von 2o Teilen Natronlauge von 4o' B6 und 5 Teilen Natriumhydrosulfit zur Lösung. Mit der auf etwa 50° C erwärmten Küpe werden Zoo Teile Asbest r/2 Stunde lang behandelt. Nach dem Abpressen, Auswaschen und Trocknen erhält man einen licht-, wasser-, alkali-, kalk- und zementecht gefärbten Asbest.Example i 10 parts of a vat dye are slurried in 2,000 parts Water and then brings it - by adding 20 parts of sodium hydroxide solution of 40 'B6 and 5 parts of sodium hydrosulfite for solution. With the vat heated to around 50 ° C Zoo parts are treated asbestos for r / 2 hour. After pressing, washing out and drying results in a color that is light, water, alkali, lime and cement resistant Asbestos.

B-eispiel2 Man trägt Zoo Teile Asbest meine Lösung, bestehend aus 12 Teilen 2, 3-Oxynapthoylanünobenzol, 12 Teilen Monopolbrillantöl, i8 Teilen Natronlauge von 40'B6 und 2ooo Teilen Wasser, ein. Man beläßt den Asbest in der Lösung etwa i 5 Minuten- und legt ihn nach dem Abpressen 15 Minuten lang in eine Lösung von 17,5 Teilen der Doppelverbindung aus Chlorzink und diazotiertem ¢-Chlor-2-nitroi-aminobenzol in 2ooo Teilen Wasser. Dann wäscht man aus und trocknet. Es wird ein hellrot gefärbter Asbest von vorzüglichen Echtheitseigenschaften .erhalten. Läßt man auf die mit 2, 3-Oxynaphthoylaminobenzol behandelte Asbestfaser die Doppelverbindung aus Chlorzink und der Diazoverbindung aus i-Amino-2-nitro-q.-methoxybenzol einwirken, so erhält man eine bordeauxrote Färbung.Example 2 One carries zoo parts asbestos my solution, consisting of 12 parts 2, 3-Oxynapthoylanünobenzol, 12 parts monopoly brilliant oil, 18 parts caustic soda of 40'B6 and 2ooo parts water. The mixture is left to asbestos in the solution is about i 5 minute and places it after pressing 1 for 5 minutes in a solution of 1 7.5 parts of the double combination of zinc chloride and diazotized ¢ chloro-2-nitroi-aminobenzene in 2ooo parts of water . Then you wash out and dry. A light red colored asbestos with excellent fastness properties is obtained. If the double compound of zinc chloride and the diazo compound of i-amino-2-nitro-q.-methoxybenzene are allowed to act on the asbestos fiber treated with 2,3-oxynaphthoylaminobenzene, a burgundy color is obtained.

Beispiel 3 Man teigt 3 Teile i-Amino-2-nitro-q.-methylbenzol mit 2 Teilen Wasser und i, 5 Teilen Natriumnitrat an, verdünnt mit 6o Teilen Wasser und gibt schnell 8 Teile Salzsäure von 2o° B6 hinzu. In die erhaltene Diazoniumsalzlösung trägt man i oo Teile fein gefaserten Asbest ein, der mit etwa 30o Teilen Wasser angeschlämmt ist. Nach dem Abquetschen wird der so präparierte Asbest in eine Lösung gebracht, die durch Lösen von 3 Teilen ß-Naphthol in i o Teilen heißem Wasser und 2,6 Teilen Natriumhydroxyd von q.0° Be hergestellt wurde und zu der vor der Kupplung noch iooTeile Wasser und ZTeile Sodaldsung (i.- i o) zugesetzt wurden. Man erhält eine scharlachrote Färbung.Example 3 3 parts of i-amino-2-nitro-q.-methylbenzene are mixed with 2 Parts of water and 1.5 parts of sodium nitrate, diluted with 60 parts of water and quickly adds 8 parts of hydrochloric acid at 20 ° B6. Into the obtained diazonium salt solution one carries in 100 parts of fine-grained asbestos, that with about 30 parts of water is slurried. After squeezing the asbestos prepared in this way, it turns into a solution brought that by dissolving 3 parts of ß-naphthol in i o parts of hot water and 2.6 parts of sodium hydroxide of q.0 ° Be was prepared and to that before the coupling 100 parts of water and Z parts of soda solution (i.- i o) were still added. You get a scarlet color.
