Abstract
Description
Die Erfindung betrifft ein Verfahren zum Imprägnieren von Holz mit siliciumorganischen Verbindungen.The invention relates to a method for impregnation of wood with organosilicon compounds.
Aus der DE-OS 29 22 343 ist ein Imprägniermittel für cellulosehaltiges Material bekannt, das aus einem Gemisch von Alkyltrialkoxysilanen, Chelaten oder Alkoholaten von Zinn oder ähnlichen Elementen und Kieselsäurereestern besteht.From DE-OS 29 22 343 is an impregnating agent for known cellulose-containing material that from a Mixture of alkyltrialkoxysilanes, chelates or Alcoholates of tin or similar elements and Silicic acid esters exist.
Es wird dort beschrieben, daß Alkyltrialkoxysilane allein keine hydrophobierende Wirkung auf Holz ausüben.It is described there that alkyltrialkoxysilanes alone do not have a hydrophobic effect on wood.
Aufgabe der Erfindung ist es, ein einfach zusammgesetztes Mittel für die Imprägnierung von Holz zu finden.The object of the invention is a simply assembled Find means for impregnating wood.
Gegenstand der Erfindung ist ein Verfahren zum Imprägnieren von Holz mit siliciumorganischen Verbindungen, dadurch gekennzeichnet, daß man das Holz mit der Lösung eines oder mehrerer Alkyltrialkoxysilane(s) der Formel R-Si(OR2)3 behandelt, in der bedeuten: R einen Alkylrest mit 3 bis 18 C-Atomen und R′ einen Alkylrest mit 1 bis 4 C-Atomen, und es anschließend bei 40 bis 90°C, bevorzugt 60 bis 85°C, trocknet.The invention relates to a process for impregnating wood with organosilicon compounds, characterized in that the wood is treated with the solution of one or more alkyltrialkoxysilanes (s) of the formula R-Si (OR 2 ) 3 , in which: R is an alkyl radical with 3 to 18 carbon atoms and R 'an alkyl radical with 1 to 4 carbon atoms, and then it dries at 40 to 90 ° C, preferably 60 to 85 ° C.
Bevorzugt eingesetzt werden Alkyltrialkoxysilane, bei denen R für einen Alkylrest mit 3 bis 8 C-Atomen steht, und R Methyl oder Ethyl bedeutet. Einsetzbar sind auch die entsprechenden Ankondensationsprodukte. Alkyltrialkoxysilanes are preferably used, in which R is an alkyl radical having 3 to 8 carbon atoms stands, and R means methyl or ethyl. Can be used are also the corresponding condensation products.
Es sind aprotische Lösungsmittel, wie z.B. Petrolether oder Testbenzin oder protisches Lösungsmittel, vor allem Alkohole, auch verdünnt mit Wasser oder Wasser allein, geeignet.They are aprotic solvents, e.g. Petroleum ether or white spirit or protic solvent all alcohols, whether or not diluted with water or water alone, suitable.
Dabei werden die protischen Lösungsmittel bevorzugt und entsprechend der Löslichkeit der siliciumorganischen Verbindungen verwendet.The protic solvents are preferred and according to the solubility of the organosilicon Connections used.
Im allgemeinen verwendet man Alkohole mit 1 bis 4 C-Atomen allein oder im Gemisch miteinander.Alcohols with 1 to 4 are generally used C atoms alone or in a mixture with each other.
Die Organosilanverbindungen werden in Form von 5 bis 85 Gew.-%igen, bevorzugt 5 bis 25 Gew.-%igen, Lösungen auf das Holz aufgebracht.The organosilane compounds are in the form of 5 to 85% by weight, preferably 5 to 25% by weight, solutions applied to the wood.
Dies kann durch Besprühen, Bestreichen oder auch Tauchen des zu imprägnierenden Holzes in die Imprägnier- Lösung geschehen.This can be by spraying, brushing or even Dipping the wood to be impregnated into the impregnated Solution happen.
Nach einer Einwirkzeit von im allgemeinen 5 bis 60 min unterzieht man das Holz bei 40 bis 90°C, bevorzugt 60 bis 85°C einer Wärmebehandlung.After an exposure time of generally 5 to 60 min the wood is subjected to at 40 to 90 ° C., preferably 60 to 85 ° C of a heat treatment.
Die Zeitdauer hängt von der angewendeten Temperatur ab und beläuft sich im allgemeinen auf 30 min bis 5 h, insbesondere auf 1 bis 2 h bei ca. 80°C.The length of time depends on the temperature used and generally amounts to 30 minutes to 5 hours, in particular for 1 to 2 h at approx. 80 ° C.
Anschließend stellt man eine deutlich reduzierte Wasseraufnahme des so behandelten Holzes fest.Then you put a significantly reduced Water absorption of the treated wood.
Es werden Probewürfel mit einer Kantenlänge von ca. 2 cm aus Kiefernkernholz hergestellt und die Schutz wirkung von Propyltrimethoxysilan (Si 103) und Octyltrimethoxysilan (Si 108) getestet.Test cubes with an edge length of approx. 2 cm made of pine heartwood and protection effect of propyltrimethoxysilane (Si 103) and Octyltrimethoxysilane (Si 108) tested.
In 10 Kristallisierschalen (Höhe 4,5 cm, Durchmesser 7,5 cm) werden nach dem Wiegen und nach dem Kennzeichnen je 5 Holzklötzchen hineingelegt und mit einem Uhrglas abgedeckt, um einen Auftrieb zu verhindern. Jeweils 100 ml einer Silanmischung werden langsam am Rand der Gefäße hinzugefügt. Nach der gewünschten Einwirkungs zeit werden die Proben entnommen, 2 h bei 80°C getrocknet und erneut gewogen.In 10 crystallizing dishes (height 4.5 cm, diameter 7.5 cm) are 5 each after weighing and after labeling Wooden blocks laid in and with a watch glass covered to prevent buoyancy. Each 100 ml of a silane mixture are slowly at the edge of the vessels added. After the desired action the samples are taken for 2 hours at 80 ° C dried and weighed again.
Zur Feststellung der Wasseraufnahme lagert man die Holzklötzchen 60 min in einem Wasserbad von 20°C und kontrolliert das Gewicht nach jeder Viertelstunde.To determine the water absorption, store the Wooden blocks for 60 min in a water bath at 20 ° C and checks the weight after every quarter of an hour.
Abb. 1 gibt die Wasseraufnahme von drei Proben wieder: Der Blindprobe, der mit einer 10%igen wäßrigen Si 103 Lösung behandelten und der mit einer 10%igen Si 108 Lösung in einem Waser/Isopropanol-Gemisch (2 : 8) behandelten Probe. Fig. 1 shows the water absorption of three samples: the blank sample, which was treated with a 10% aqueous Si 103 solution and the sample treated with a 10% Si 108 solution in a water / isopropanol mixture (2: 8).
Es zeigt sich eine deutliche Reduzierung der Gewichts zunahme bei den imprägnierten Hölzern.There is a significant reduction in weight increase in impregnated woods.
