Abstract
Description
Als reaktionsfählger Mineralstoff kann außer Gips Zement einzeln oder in geeigneter Kombination eingesetzt werden. Besondere Farbwlrkungen der beschichteten organischen Fasern können vorteilhaft dadurch erzielt werden, daß die Mlschung vor der Aushärtung des Mineralstoffs oder der Mineralstoffe pigmentiert wird. In addition to gypsum, cement can be used as a reactive mineral or used in a suitable combination. Special color effects of the coated organic fibers can advantageously be achieved by the fact that the mash before the hardening of the Mineral or the minerals pigmented will.
Die farbgebenden Pigmente können während der Tränkung der Fasern oder auch noch während des Preßvorgangs zugesetzt werden.The coloring pigments can be used during the impregnation of the fibers or can also be added during the pressing process.
Es hat sich gezeigt, daß ein besonders zweckmäßiges Verfahren für die Feinzerkleinerung der getrockneten Masse darin besteht, daß erfindungsgemäß die Feinzerkleinerung der getrockneten Masse spanabhebend und zerrupfend durchgeführt wird, Insbesondere mit Hilfe von Schlelfvorrichtungen, wodurch sich eine flockige Masse der beschichteten organischen Fasern ergibt, die sich besonders gut weiterverarbeiten läßt und besonders dauerhafte und wirksame Eigenschaften bei Verwendung als Zuschlag- und/oder Füllstoff für weiterverarbeitbare Massen aufweist. It has been shown that a particularly useful method for the fine comminution of the dried mass consists in that according to the invention the fine comminution of the dried mass is carried out by cutting and tearing becomes, in particular with the help of Schlelfvorrichtungen, creating a flaky Mass of the coated organic fibers results, which can be further processed particularly well and particularly durable and effective properties when used as an aggregate and / or has filler for further processable masses.
Das Verfahren der Erfindung wird prinzipiell in folgender Weise durchgeführt: Die organischen Fasern werden in einer Suspension aus einem oder mehreren gewünschten reaktionsfähigen natürlichen und/oder synthetischen Mineralstoffen und Wasser mit diesen innig und homogen vermlscht. Die jeweiligen Anteile von Wasser und Mineralstoff bzw. Mineralstoffen werden je nach den Mineralstoffen wie auch in Abhängigkeit von der durchschnittlichen Faserlänge der organischen Fasern gewählt. The method of the invention is carried out in principle in the following way: The organic fibers are desired in a suspension of one or more reactive natural and / or synthetic minerals and water with this intimately and homogeneously mingled. The respective proportions of water and minerals or minerals are depending on the minerals as well as depending on the average fiber length of the organic fibers.
Das so erzielte Gemenge wird einem geeigneten Preßvorgang unterworfen, dessen Ergebnis eine plastische Masse ist. Dabei wird insbesondere überschüssiges Wasser entfernt und eine erste Haftung der Beschichtung an der organischen Faser erreicht. Während des Preßvorgangs kann die Aushärtung der die Beschichtung bildenden Mineralstoffe beginnen. The mixture obtained in this way is subjected to a suitable pressing process, the result of which is a plastic mass. In particular, excess Removes water and initial adhesion of the coating to the organic fiber achieved. During the pressing process, the curing of the coating forming Minerals begin.
Die eigentliche teilweise oder vollständige Aushärtung des Mineralstoffs oder der Mineralstoffe erfolgt vor oder In dem anschließenden gesteuerten Trocknungsprozeß. The actual partial or complete hardening of the mineral or the minerals take place before or in the subsequent controlled drying process.
Ist die Masse nach dem Trocknungsvorgang erstarrt, so wird die getrocknete Masse feinzerkleinert, insbesondere durch spanabhebendes Zerkleinern und Zerrupfen beispielsweise mittels Schlelfvorrichtungen. Das Ergebnis ist eine flockige Masse aus den beschichteten Fasern. If the mass has solidified after the drying process, then the dried one The mass is finely ground, in particular by chipping and tearing for example by means of key devices. The result is a flaky mass from the coated Fibers.
Diese flockige Masse kann dann als Zuschlag- und/oder Füllstoff in den geschilderten weiterverarbeltbaren Massen und Putzen eingesetzt werden.This flaky mass can then be used as an aggregate and / or filler in the described masses and plasters that can be processed further are used.
Eine besonders vorteilhafte und bevorzugte Ausführungsform der Erfindung wird Im folgenden näher erläutert: Es werden 45 Vol.-% Cellulosefasern mit 55 Vol.-% handelsüblichen gebrannten Glpses in einem Gemenge mit mindestens der stöchlometrisch erforderlichen Wassermenge homogen und Innig gemischt, wobei gleichzeitig eine Intensive Tränkung der Cellulosefasern erzlelt wird. A particularly advantageous and preferred embodiment of the invention is explained in more detail below: There are 45 vol .-% cellulose fibers with 55 vol .-% commercial distilled Glpses in a mixture with at least the stoichlometric required amount of water homogeneously and intimately mixed, at the same time an intensive Impregnation of the cellulose fibers is elaborated.
Die hierbei entstandene Mischung wird einem Preßvorgang bei einem Druck von 15 bis 30 N/mm2 unterworfen, wodurch eine plastische Masse entsteht. The resulting mixture is a pressing process at a Subjected to pressure of 15 to 30 N / mm2, creating a plastic mass.
Diese plastische Masse bindet anschließend ab und wird auf dem Wege der Trocknung für die mechanische Zerkleinerung vorbereitet. Ist die Masse in gewünschtem Maß getrocknet, so wird diese getrocknete Masse mit Hilfe von Schleifvorrichtungen spanabhebend und zerrupfend zu einer flockigen Masse feinzerklelnert. Diese Zerkleinerung wird zweckmäßig derart durchgeführt, daß sich überwiegend beschichtete Fasern von einer Länge von nicht mehr als 2 mm ergeben. This plastic mass then binds and is on the way prepared for mechanical crushing after drying. Is the measure in the desired Measure dried, so this dried mass is with the help of grinding devices Finely chopped and torn into a flaky mass. This crushing is expediently carried out in such a way that predominantly coated fibers of a length of not more than 2 mm.
Untersuchungen zeigten, daß die hierdurch erreichte Beschichtung der Cellulosefasern mit Glpskrlstallen einen festen Verbund mit den Faseroberflächen elngegangen war. Das entstandene Produkt weist folgende wesentliche Eigenschaften auf: Sehr schwer entflammbar. Investigations showed that the coating achieved in this way The cellulose fibers with Glpskrlstallen a firm bond with the fiber surfaces had gone. The resulting product has the following essential properties on: Very flame retardant.
Kristallwassergehalt: ca. 12X pH-Wert: ca. 7,2 Farbe: grau alkalibeständig. Water of crystallization: approx. 12X pH value: approx. 7.2 Color: gray, alkali-resistant.
