AN OIL/OIL/WATER TYPE EMULSION AND METHOD OF USING THE SAME FOR PRESERVATIVE TREATMENT OF PINE WOOD
An oil/oil/water type emulsion and a method for impregnation of pine wood. Water phase of the emulsion comprises a water solution of boron compounds (borax, boric acid) and quaternary ammonium compounds. First oil phase comprises rapeseed oil as the dispersed phase and an emulsifier (an unsaturated...

| description | An oil/oil/water type emulsion and a method for impregnation of pine wood. Water phase of the emulsion comprises a water solution of boron compounds (borax, boric acid) and quaternary ammonium compounds. First oil phase comprises rapeseed oil as the dispersed phase and an emulsifier (an unsaturated fatty acid or their mixture). Second oil phase comprises polysiloxane particles dispersed on the surface of the first oil phase to improve hydrophobisation. Emulsion is prepared by emulsifying polysiloxane with rapeseed oil and the emulsifier. Then the mixture is emulsified with a water solution by pulsation-type emulsif ication device at a pulsation frequency from 800 to 1,200 Hz. Wood impregnated by this method has good antiseptic properties against wood-decaying and wood-colouring fungi as well as reduced wash-out of the active agents. Its surface can be covered with non-transparent or transparent coating, and the electrical properties are similar to unimpregnated wood.
L'invention concerne une émulsion de type huile/huile/eau et un procédé d'imprégnation du bois de pin. La phase aqueuse de cette émulsion contient une solution aqueuse de composés de bore (borax, acide borique) et de composés d'ammonium quaternaires. Une première phase huileuse contient de l'huile de colza comme phase dispersée et un émulsifiant (un acide gras insaturé ou un mélange associé). La deuxième phase huileuse contient des particules de polysiloxane dispersées sur la surface de la première phase huileuse pour améliorer l'hydrophobisation. L'émulsion selon l'invention est obtenue par émulsification du polysiloxane avec l'huile de colza et l'émulsifiant. Ce mélange est ensuite émulsifié avec une solution aqueuse au moyen d'un dispositif d'émulsification de type à pulsations, à une fréquence de pulsations comprise entre 800 et 1 200 Hz. Le bois imprégné par la mise en oevre de ce procédé présente de bonnes propriétés antiseptiques contre la pourriture du bois et les champignons qui colorent le bois, ainsi qu'un lessivage réduit des agents actifs. La surface du bois peut être recouverte d'un revêtement transparent ou non transparent et les propriétés électriques sont similaires à celles du bois non imprégnés. |
