Abstract
Description
Die Erfindung betrifft ein Verfahren zur Herstellung von Bauplatten, die aus organischen und/oder anorganischen Fasern als Armierung und aus wenigstens einem anorganischen Bindemittel, wie Zement und gegebenenfalls aus Füllstoffen bestehen.The invention relates to a method for producing building boards, those made of organic and / or inorganic fibers as reinforcement and from at least one inorganic binder, such as cement and optionally consist of fillers.
Organische Fasern, insbesondere solche aus Zellulose, haben den Nachteil, daß sie von den im Zement enthaltenen, kristallisierbaren Zementreaktionsprodukten angegriffen und langfristig zerstört werden, so daß ihre Standzeit begrenzt ist.Organic fibers, especially those made of cellulose, have the Disadvantage that they are crystallizable from those contained in the cement Cement reaction products attacked and destroyed in the long term be so that their service life is limited.
Der Erfindung liegt demgemäß die Aufgabe zugrunde, ein Verfahren der eingangs genannten Art so auszugestalten, daß die Nachteile des bekannten Verfahrens beseitigt werden und daß sich die Kristallisationsprodukte nicht mehr auf die Fasern auswirken können. The invention is accordingly based on the object of a method of the type mentioned in such a way that the disadvantages of the known method are eliminated and that the Crystallization products can no longer affect the fibers.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Fasern vor ihrer Eintragung in das Faser-Bindemittel-Gemisch mit einer Tränkung und/oder einem Überzug aus hydrophoben Substanzen versehen werden.This object is achieved in that the fibers with an impregnation before they are entered into the fiber-binder mixture and / or a coating of hydrophobic substances.
Auf diese Weise wird erreicht, daß einerseits beispielsweise das im Zement enthaltene Sulfat die Fasern nicht angreifen kann und daß andererseits Kristallisationsprodukte, wie beispielsweise Ettringit als Calciumsulfat-Silikathydrat sich ebenfalls nicht auf die Fasern auswirken kann, weil diese nicht mehr wasserauf nahmefähig sind.In this way it is achieved that, for example, on the one hand the sulfate contained in the cement cannot attack the fibers and that, on the other hand, crystallization products such as Ettringite as calcium sulfate silicate hydrate is also not can affect the fibers because they no longer water are acceptable.
Ein weiterer Vorteil des erfindungsgemäßen Verfahrens besteht darin, daß das Quellen und Schwinden der Fasern durch die Tränkung mit den hydrophoben Substanzen weitgehend verringert ist.Another advantage of the method according to the invention is in that the swelling and shrinking of the fibers due to the impregnation is largely reduced with the hydrophobic substances.
Es können verschiedene hydrophobe Substanzen zur Anwendung kommen. So ist es beispielsweise möglich, Silikonverbindungen hierfür zu verwenden oder Öle, Paraffin od. dgl.; besonders vorteilhaft ist es jedoch, wenn die hydrophobe Substanz Bitumen ist, weil im Gegensatz zu anderen hydrophoben Substanzen, wie beispielsweise Ölen, Bitumen langzeitig, nämlich über Jahrzehnte hinaus, beständig ist.Various hydrophobic substances can be used. For example, it is possible to add silicone compounds for this use or oils, paraffin or the like; However, it is particularly advantageous if the hydrophobic substance is bitumen because unlike other hydrophobic substances, such as oils, bitumen long-term, namely for decades.
Eine solche Tränkung ist insbesondere für verrottbare organische Fasern, wie Zellulosefasern, Holzspäne, Flachsfasern, Hanffasern und andere Fasern dieser Art geeignet, aber auch anorganische Fasern, wie beispielsweise Glasfasern, werden durch einen solchen hydrophoben Überzug geschützt. Glasfasern werden bei spielsweise gegen ein schädliches Aufkristallisieren, also eine Verwachsung mit der Matrix, geschützt.Such an impregnation is particularly for rotting organic Fibers such as cellulose fibers, wood chips, flax fibers, hemp fibers and other fibers of this type are suitable, but also inorganic Fibers, such as glass fibers, are replaced by a protected such a hydrophobic coating. Glass fibers are used at for example, against a harmful crystallization, i.e. one Adhesion to the matrix, protected.
Bei anorganischen Fasern, wie Steinwolle, schützt der hydrophobe Überzug gegen einen aus dem Bindemittel kommenden Alkaliangriff.The hydrophobic protects inorganic fibers such as rock wool Coating against an alkali attack coming from the binder.
