Description

Verfahren zur Herstellung eines faserverstärkten Baumaterials aus Zement, Wasser, Sand und schaumerzeugenden und schaumstabilisierenden Stoffen Zusatz zur Patentanmeldung C 19353 VI b/ 80 b (Auslegeschrift 1124 415) In der Patentanmeldung C 19353 VIb/80b ist die Herstellung eines faserverstärkten, zementhaltigen Baumaterials, insbesondere von faserverstärktem Leichtbeton beschrieben worden, die nach der Erfindung unter Zuhilfenahme von Mineralfasern, wie z. B. Basaltwolle, mit einfachen Mitteln bei hoher Wirtschaftlichkeit möglich ist, wenn man eine wäßrige, schaumerzeugende und schaumstabilisierende Stoffe und vorzugsweise außerdem Alginate enthaltende Harzlösung oder -emulsion, vorzugsweise auf der Basis von klebenden Harzen, wie z. B. Kolophonium, Zement, Sand und Wasser unter Zusatz von Mineralfasern, vorzugsweise Basaltfasern, für wenige Minuten kräftig durchmischt.Process for the production of a fiber-reinforced building material from cement, water, sand and foam-producing and foam-stabilizing substances Addition to patent application C 19353 VI b / 80 b (Auslegeschrift 1 124 415) In patent application C 19353 VIb / 80b, the production of a fiber-reinforced, cement-containing building material, in particular of fiber-reinforced lightweight concrete has been described, which according to the invention with the aid of mineral fibers, such as. B. basalt wool, is possible with simple means with high economic efficiency if you have an aqueous, foam-producing and foam-stabilizing substances and preferably also alginates-containing resin solution or emulsion, preferably based on adhesive resins, such as. B. rosin, cement, sand and water with the addition of mineral fibers, preferably basalt fibers, vigorously mixed for a few minutes.

Es hat sich nunmehr weiterhin herausgestellt, daß man eine besonders vollkommene und innige Verbindung der gleichmäßig verteilten mineralischen Fasern, vorzugsweise Basaltfasern, mit den Betonbestandteilen, d. h. dem Zement und Sand, .dann erreicht, wenn man auf der Faser aus einer wäßrigen Lösung von Alkalisilikaten mit Hilfe von Säuren Kieselsäure niederschlägt. Derartige Fasern besitzen eine hochaktive, vorzugsweise aus Kieselsäure bestehende, fest mit der Faser verbundene Belagschicht. Durch Vorbehandlung der Faser mit Säuren kann ihr zusätzlich eine unregelmäßige und vergrößerte Oberflächenstruktur gegeben werden, die nach der Erzeugung des Kieselsäureniederschlages eine besonders innige Verzahnung und feste Bindung mit den Betonteilen herbeiführt.It has now also turned out that one special perfect and intimate connection of the evenly distributed mineral fibers, preferably basalt fibers, with the concrete components, d. H. the cement and sand, .then achieved when one on the fiber from an aqueous solution of alkali silicates with the help of acids silicic acid precipitates. Such fibers have a highly active, The covering layer is preferably made of silica and is firmly connected to the fiber. By pretreating the fiber with acids you can also get an irregular and increased surface structure are given after the formation of the silica precipitate brings about a particularly close interlocking and firm bond with the concrete parts.

ES ist schon bekannt, auf Faserstoffen Siliciumdioxyd zur Aufrauhung der Oberfläche niederzuschlagen. Mit Siliciumdioxyd können die vorteilhaften Effekte der Niederschlagung von Kieselsäure, nämlich die innige Verbindung zwischen Mineralfaser und Zement, nicht erreicht werden.It is already known to use silicon dioxide on fiber materials for roughening knock down on the surface. Using silica can have beneficial effects the precipitation of silica, namely the intimate connection between mineral fibers and cement, cannot be achieved.

Zur Erzeugung des Kieselsäureniederschlags auf der Mineralfaser kann man z. B. in folgender Weise vorgehen: Kieselgar wird in Natronlauge gekocht, wobei die kieselsäurehaltigen Anteile der Infusorienerde (Diatomeenschalen) in Lösung gehen. Man trägt in diese Lösung die vorzubehandelnden Fasern ein, gibt eine Säure, z. B. Salzsäure oder Kohlensäure, zu und fällt hierdurch die Kieselsäure auf der von der Säure benetzten Faser aus.To generate the silica precipitate on the mineral fiber can one z. B. proceed in the following way: Kieselgar is boiled in sodium hydroxide solution, whereby the silica-containing parts of the infusor earth (diatom shells) in solution walk. The fibers to be pretreated are added to this solution, an acid is added, z. B. hydrochloric acid or carbonic acid, and thereby falls the silica on the fiber wetted by the acid.

Die Alkalisilikatlösung, aus der die als Niederschlagsschicht für die Faser bestimmte Kieselsäure gefällt wird, kann auch auf andere Weise gewonnen werden.The alkali silicate solution that is used as a precipitation layer for The fiber certain silica is precipitated can also be obtained in other ways will.
