Description

Masse für Bauplatten aus Pflanzenfasern und Verfahren zur Herstellung derselben Es ist bekannt, daß in tropischen Ländern Bauplatten aus Pflanzenfasern den gestellten Anforderungen auf die Dauer nur gewachsen sind, wenn sie termitenfest sind. Als Mittel zur Erreichung dieses Zieles wurde bisher Pentachlorphenol empfohlen, welches auf die Faser fixiert wurde. Nachdem in den wäßrigen Lösungen, insbesondere in den Abwässern, ein Teil dieser Stoffe verlorengeht und auch zu Schwierigkeiten in den gewerblichen Abwässern führt, mußte von der Anwendung dieses ?Mittels Abstand genommen werden.Composition for building panels made from vegetable fibers and method of manufacture The same It is known that in tropical countries building panels made of plant fibers can only cope with the requirements in the long run if they are termite-proof are. As a means of achieving this goal, pentachlorophenol has so far been recommended, which was fixed on the fiber. After in the aqueous solutions, in particular in the sewage, some of these substances are lost and also cause difficulties in commercial wastewater had to refrain from using this? compound be taken.

Die erläuterten Mängel werden erfindungsgemäß dadurch vermieden, daß man die organischen Faserstoffe mit Emulsionen von teerartigen Stoffen behandelt. Dabei werden gleichzeitig chlorierte Phenole zugesetzt. Es können auch andere halogenierte, aromatische Kohlenwasserstoffe verwendet werden. Mit diesen Stoffen werden die Pflanzenfasern unter Anwendung sauer reagierender Stoffe und gleichzeitig mit Gelen amorpher Polysilikate, wie Na- oder K-Wasserglas, und/oder mit Leimstoffen natürlicher und künstlicher Herkunft behandelt.The deficiencies explained are avoided according to the invention in that the organic fibers are treated with emulsions of tarry substances. Chlorinated phenols are added at the same time. Other halogenated, aromatic hydrocarbons are used. These substances are used to make the plant fibers using acidic substances and at the same time with gels of amorphous polysilicates, like Na or K water glass, and / or with glue substances more natural and artificial Origin treated.

Beispielsweise wird die erfindungsgemäße Behandlung in folgender Weise durchgeführt: Es wird ein Gemisch aus 80 bis 83°/o Pflanzenfasern, beispielsweise aus zerfasertem Holz oder Holzschliff, 10 bis 12% Teer und aus Zusätzen von 0,3 bis 0,-1% chlorierten Phenolen und 0,1% halogenierten, aromatischem Kohlenwasserstoffen, z. B. Chlorkresol oder Chlornaphthalin, hergestellt. Bei dieser geringen Konzentration ergeben sich keine \'erunreinigungen in den Abwässern, die auf Lebewesen eine schädigende Einwirkung haben, sofern die in der Faserstoffcliemie gebräuchliche Verdünnung eingehalten wird. Die erwähnten Stoffe werden in den wäßrigen Faserstoffbrei eingearbeitet, unter weiterem Zusatz einer 1%igen Harzlösung (Naturharz oder Kunstharz). Ferner «-erden in Form von Gelen 61.10 amorpher Silikate (Natrium- oder Kaliumsilikat) beigemischt. Diese Stoffe «-erden auf den Fasern im Faserstoffbrei fixiert, z. B. mit Hilfe von :\lumiiiiutnsulfat, Schwefelsäure u. dgl. Anschließend «-erden in bekannter Weise Faserstoffplatten und Bauplatten erzeugt und in Trockenanlagen oder gebeizten Pressen getrocknet. Die Platten können mit einer Deckschicht versehen «-erden, die weiß oder farbig gehalten sein kann. le nach Dicke der Deckschicht muß auch diese erfindungsgemäß behandelt werden, um Termitenfestigkeit zu gewährleisten. Deckstoffe werden in Wasser aufgeschlämmt aufgetragen, so claß eine Verfilzung der Grundstoffschicht mit der Deckstoffschicht eintritt.For example, the treatment of the present invention is carried out in the following manner carried out: It is a mixture of 80 to 83% vegetable fibers, for example from fiberized wood or wood pulp, 10 to 12% tar and from additives of 0.3 up to 0.1% chlorinated phenols and 0.1% halogenated aromatic hydrocarbons, z. B. chlorocresol or chloronaphthalene produced. At this low concentration there are no \ 'impurities in the wastewater that are harmful to living beings Have an effect, provided that the dilution customary in the fibrous industry is adhered to will. The substances mentioned are incorporated into the aqueous pulp, with further addition of a 1% resin solution (natural resin or synthetic resin). Further «Earths in the form of gels 61.10 of amorphous silicates (sodium or potassium silicate) mixed in. These substances «-erden fixed on the fibers in the pulp, z. B. with the help of: sulphate, sulfuric acid and the like known way fiber boards and building boards produced and in drying plants or dried pickled presses. The panels can be provided with a top layer «Earth, which can be white or colored. le according to the thickness of the top layer this must also be treated according to the invention in order to ensure resistance to termites. Cover materials are slurried in water, so that the matting occurs Base material layer enters with the cover material layer.
