Method of particleboard protection against fungi and substance for particleboard protection against fungi

摘要

The present invention relates to a method of antifungal protection of particleboards and the substance for such an antifungal protection of particleboards based on an application of ionic liquids. A method of antifungal protection of particleboards comprising an introduction of a fungicide into an adhesive resin characterized in that a dispersion of an ionic liquid of the general formula 1, wherein: - R 1 stands for benzyl, an alkyl substituent with the carbon chain length of C 1-20 , or an unsaturated hydrocarbon substituent with the carbon chain length of C 3-20 and characterized by one or more than one multiple chemical bonds, - R 2 , R 3 are equal and stand for alkyl substituents with the carbon chain length of C 1-16 or unsaturated hydrocarbon substituents with the carbon chain length of C 3-16 and characterized by one or more than one multiple chemical bonds, - R 4 stands for an alkyl substituent with the carbon chain length of C 1-20 , or an unsaturated hydrocarbon substituent with the carbon chain length of C 3-20 and characterized by one or more than one multiple chemical bonds, - X represents a nitrate(III), or nitrate(V), or propionate, or dicyanimide, or dodecylbenzenesulfonate anion, in a solution of an adhesive resin used for particleboard bonding is prepared and, subsequently, the so prepared composition of the resin and the ionic liquid dispersion is spread onto the chips with known methods and, thus, the process of particleboard production is continued.
