Description

Verfahren zum Färben von Sand u. dgl. Gegenstand der Erfindung ist ein Verfahren, wonach Sand, Kies., Schlacken und ä hnliche@' körnige Stoffe bzw. daraus herzustellende Erzeugnisse, wie Formsteine, Verputzmassen u. dgl., mit einem gegen inechan fische Abnutzung und Wettereinflüsse dauernd widerstandsfähigen Farbüberzug versehen werden.A method for coloring sand and the like is an object of the invention a process whereby sand, gravel, slag and similar granular substances or Products to be produced therefrom, such as shaped stones, plastering compounds and the like, with a Paint coating that is permanently resistant to mechanical wear and weather influences be provided.

Zu diesem Zweck wurden .die zu färbenden Körner bisher unter anderem auch mit Suspernsionen von Chromoxyd in Wasserglaslösitng überzogen und die erhaltenen überzüge durch Zusatz entsprechender Salzc sowie durch in oxydierender Atmosphäre vorgeno:mm,enes Glühen bis über die Schinelztemperatur des Natriumsilicats in wasserunlösliche Form übergeführt und mit den gefärbten Körnern versintert.For this purpose, the grains to be colored have hitherto been among other things also coated with suspensions of chromium oxide in water glass solution and the obtained Coatings through the addition of appropriate salts and through in an oxidizing atmosphere vorgeno: mm, a glow up to above the shingle temperature of sodium silicate in water-insoluble Form transferred and sintered with the colored grains.

Gemäß der Erfindung können nun überraschenderweise gleichermaßen dauerba.fte und widerstandsfähige Farbüberzüge in wesentlich einfacherer und wohlfeilerer Weisie, d.li. ohne Zusatz von Chemikalien und ohne Glühurig bzw.. Sinterung erhalten «.erden, wenn man die Wasserglaslösung und die darin suspendierten, aus Chromoxyd bestehenden Überzüge in der Kälte genügend lang der atmoisphäris.ch:cii Luft oder einer anderen oxydierenden Atmosphäre aussetzt und nach Erhärtung ebenfalls in der Kälte mit Wasser wäscht.According to the invention, it is now possible, surprisingly, to last equally and resistant paint coatings in a much simpler and cheaper way, d.li. without the addition of chemicals and without incandescent or sintering «. when you consider the waterglass solution and the chromium oxide suspended in it Coats in the cold for long enough of the atmoisphäris.ch: cii air or another exposed to an oxidizing atmosphere and, after hardening, also in the cold with water washes.

Um z. B. i oo kg Sand zur Verwendung in Wandverputzmörtel oder als Sportplatzbelag sattgrün zu färben, suspendiert man i,5 kg Chromoxyd in einer aus 15 kg Wasserglas (36 bis 38 B6) und iokg Wasser bestehenden Lösung, vermischt damit den Sand bis zum Überziehen seiner :einzelnen Körner, breitet die Masse in dünner Schicht im Freien aus und sorgt z. B. durch wiederholtes Wenden für starke und gleichmäßige Belüftung. Sobald die Farbüberzüge, je nach den Belüftungsverhältnissen in längstens einigeiz wenigen Tagen, erhärtet sind, löst man eventuell vorhandene, durch Zusammenkleben mehreT er Körner :entstandene Klümpchen z. B. durch Absieben.: auf und wäscht die Masse in kaltem Wasser, worauf sie unmittelbar bzw. nach Ausdünstung des anhaftenden Waschwasserrestes für beliebige an. sich @ bekannte Zwecke verwendungsbereit ist. .To z. B. To dye 100 kg of sand for use in wall plastering mortar or as a sports field covering, 1.5 kg of chromium oxide is suspended in a solution consisting of 1 5 kg of water glass (36 to 38 B6) and 10 g of water, and the sand is mixed with it until it is coated its: individual grains, spreads the mass in a thin layer in the open air and provides z. B. by repeatedly turning for strong and even ventilation. As soon as the paint coatings have hardened, depending on the ventilation conditions, in a few days at the most, any existing grains that may have been stuck together can be loosened: lumps that have arisen, e.g. B. by sieving .: and washes the mass in cold water, whereupon it immediately or after evaporation of the adhering washing water residue for any. @ known purposes is ready for use. .

Auch vorgeformte Gegenstände aus den eingangs angedeuteten und ähnlichen z. B: keramischen Massen können durch Taucli-In in Chromoxyd-Wasserglas-Suspension hzü-. durch deren Aufspritzen ,durch anschließendes Belüften und Waschen in der Kälte einwandfrei und dauerhaft gefärbt «-erden.Also preformed objects from those indicated at the beginning and the like z. B: Ceramic masses can be made by Taucli-In in chromium oxide-water glass suspension hzü-. by spraying them on, then venting and washing them in the Cold perfectly and permanently colored «earth.

Zur Abstufung bzw. Tönung der Chromoxy#dfärbung sind Zusätze entsprechender I'igin,ente bnv. wasserlöslicher Farben zur Suspension geeignet.Additives are more appropriate for grading or tinting the chromium oxide color I'igin, duck bnv. water-soluble paints suitable for suspension.
