Abstract

Mineral is based on a reversibly swellable 3-layer mineral of large-faced crystalline type, with disconnected crystal layer. This is produced from fine-grained vermiculite, hydro-mica or even nonswellable mineral with these minerals deposited within the crystals with >50 (>75)wt. % tabular crystals with extremely thin, uniformly planae tubular crystals with a thickness of 0.5-10(0.5-5) mu m and face dimensions corresponding to an equiv. dia. of 10-200 mu m and a ratio of thickness/equiv. dia. =1.10, (=1.20). The particles have hydrophilic properties at the planar faces, which rapidly take up or yield polar liquids, such as water, and strong adhesion or cohesion, which leads to shrinkage only in one direction, i.e. perpendicular to the tabular plane, on drying the particles from a dispersion in a polar liquid (water) or moistening the dray material. The particles lie over one another in layers and gave a plasticity of 35-65 wt. % dry material w.r.t. the moist material. Mineral is used partic. as refractory binder for the prodn. of mouldings and films and as release agent. It is also useful as carrier for various materials, e.g. plant protection agents.

Description

" Mineralischer Stoff auf Basis eines"Mineral substance based on a

reversibel quellbaren, grossflächig kristallin ausgebildeten Dreischichtminerals mit von einander gelösten Kristallschichten " Vermiculit gehört zu den glimmerartigen Tonmineralen,die ein quellbares Kristallgitter besitzen und deren Kristalle lamellar aufgebaut sind.Es steht der Gruppe der Montmorin-Saponit-Minerale nahe. reversibly swellable, large-area crystalline three-layer mineral with separated crystal layers " Belongs to vermiculite to the mica-like clay minerals, which have a swellable crystal lattice and whose crystals are lamellar. It belongs to the group of montmorin saponite minerals vicinity.

Das Mineral gehört zu den Dreischichtsilikaten und hat zwischen den sogenannten Schichtpaketen Wasser eingelagert. Wegen der nicht starr miteinander verbundenen Schichtpakete besitzt Vermiculit ein innerkristallines Quellvermögen.Damit hängt die Fähigkeit zuswniiien,dass sich Vermiculit-Kristalle beim raschen Erhitzen bis zum etwa 30-fachen ihrer ursprdnglichen Dicke in einer Richtung expandieren.The mineral belongs to the three-layer silicates and has between the so-called shift packages of water stored. Because of not being rigid with each other connected layer packages, vermiculite has an inner-crystalline swelling capacity depends on the ability to separate vermiculite crystals when heated rapidly expand up to about 30 times their original thickness in one direction.

Zu dieser Kenntnis der Struktur und der Eigenschaften von Vermiculit wird auf folgende Literatur verwiesen: Siehe Seite 6, Zeile 1 bis 6, Nach Römpps Chemie-Lexikon,Frankh' suche Verlagshandlung,Stuttgart,7.Auflage,1977, Ziffer 3000, weist Vermiculit im Idealfall eine ungefähre Zusmensetzung folgender Formel auf: Mg3(Al,Si)4O10(OH)2.(H2O)4.To this knowledge of the structure and properties of vermiculite reference is made to the following literature: See page 6, lines 1 to 6, according to Römpps Chemie-Lexikon, Frankh 'search publishing house, Stuttgart, 7th edition, 1977, item 3000, ideally, vermiculite has an approximate composition of the following formula: Mg3 (Al, Si) 4O10 (OH) 2. (H2O) 4.

Vermiculit enthält zusätzlich erhebliche Mengen an gebundenem Eisen (Fe), Diese Eigenschaft der Expandierung zeigen auch "Hydroglimmer" sowie "Wechselachicht-( mixed layer-) kinerale".Unter den zuletzt genannten Mineralen sind solche zu verstehen, in denen beispielsweise Vermiculit-Schichten mit Glimmer-Schichten in wechselnder,ungeordneter Folge kristallisieren.Vermiculite also contains significant amounts of bound iron (Fe), "Hydroglimmer" and "Wechselachicht- ( mixed layer-) kinerale ". The last mentioned minerals are to be understood as in which, for example, vermiculite layers with mica layers in alternating, disordered Crystallize episode.

Die Definition des mineralischen Ausnngs-1 stoffes Vermiculit ergibt sich aus Hugo Strunz,luineralogische Tabellen, 5.Auflage,Leipzig 197O,Akademische Verlagsgesellschaft,Geest & Portig KG, Seite 447. The definition of the mineral base material vermiculite results from Hugo Strunz, Luineralogical tables, 5th edition, Leipzig 197O, Academic Verlagsgesellschaft, Geest & Portig KG, page 447.

Die Definition des mineralischen Ausgangsstoffes Hydroglimmer ergibt sich aus Salmang-Scholze in "Die physikalischen und chemischen Grundlagen der Keramik", Springer Verlag,New York,1968. The definition of the mineral raw material hydro mica results from Salmang-Scholze in "The physical and chemical foundations of ceramics", Springer Verlag, New York, 1968.

Zur Herstellung des mineralischen stoffes gemäss der Drfindung auf Basis eines reversibel quellbaren,gros.sflächig kristallin ausgebildeten Dreischichtminerals werden diese Minerale verwendet. For the production of the mineral substance according to the drfindung on Basis of a reversibly swellable, large, crystalline three-layer mineral these minerals are used.

Diese Tonminerale besitzen ihrerseits nicht die Eigenschaften des mineralischen Stoffes der Srfindung,namlich die neue Struktur,die zu starken Adhäsions-und Kohäsions-Kräften sowie zu einem bestimmten Schwundverhalten beim Trocknen aus einer Dispersion oder der befeuchteten Trockenmasse führt. These clay minerals do not have the properties of mineral substance of the invention, namely the new structure, which leads to strong adhesion and Cohesion forces as well as a certain shrinkage behavior when drying from a Dispersion or the moistened dry matter leads.

Diese neue Struktur des mineralischen Stoffes gemäss der Erfindung stellt eine neue Aufgabenstellung dar. This new structure of the mineral substance according to the invention represents a new task.

Diese ergibt sich aus den tafelförmigen Teilchen mit extrem dünnen,gleichmässig ebenen Teilchen mit einer Dicke von 0,5 bis 10 Mikron und mit einem äquivalentem Durchmesser von 10 bis 200 Mikron und einem Verhältnis Teilchendicket äquivalentem Durchmesser gleich oder kleiner 1 : 10,dessen Teilchen hydrophile Sigen- schaften an den ebenen Teilchen aufweisen'die rasch polare Flüssigkeiten wie Wasser aufnehmen oder abgeben. This results from the tabular particles with extremely thin, uniform planar particles with a thickness of 0.5 to 10 microns and an equivalent Diameters of 10 to 200 microns and a particle-to-ticket ratio equivalent Diameter equal to or less than 1:10, the particles of which are hydrophilic societies on the flat particles, which quickly absorb polar liquids such as water or give up.

Der mineralische Stoff gemäss der irfindung entsteht erst durch einen Umwandlungeprozess aus diesen Ausgangsmineralen, Bs wurde nun ein mineralischer Stoff auf Basis eines reversibel quellbaren, grossflächig ausgebildeten Dreischichtminerale mit von einander gelösten Eristallechichten gefunden.The mineral substance according to the invention is only created by one Transformation process from these starting minerals, Bs now became a mineral Substance based on a reversibly swellable, large-area three-layer mineral found with separated eristal layers.

Die Erfindung ist in den Ansprüchen definiert.Ausserdem ist der mineralische Stoff gemäss der Erfindung beim Deutschen Patentamt hinterlegt.The invention is defined in the claims. Furthermore, the mineral Substance according to the invention deposited at the German Patent Office.
