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:
- R1 stands for benzyl, an alkyl substituent with the carbon chain length of C1-20, or an unsaturated hydrocarbon substituent with the carbon chain length of C3-20 and characterized by one or more than one multiple chemical bonds,
- R2, R3 are equal and stand for alkyl substituents with the carbon chain length of C1-16 or unsaturated hydrocarbon substituents with the carbon chain length of C3-16 and characterized by one or more than one multiple chemical bonds,
- R4 stands for an alkyl substituent with the carbon chain length of C1-20, or an unsaturated hydrocarbon substituent with the carbon chain length of C3-20 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.
本发明涉及一种刨花板防霉保护方法和基于离子液体应用的刨花板防霉保护物质。
一种刨花板防霉保护方法,包括将杀真菌剂引入粘合剂树脂中,其特征在于将通式为 1.A.的离子液体分散在粘合剂树脂中、
其中
- R1代表苄基、碳链长度为C1-20的烷基取代基、或碳链长度为C3-20的不饱和烃取代基,其特征为一个或一个以上的多重化学键、
- R2、R3 相等,代表碳链长度为 C1-16 的烷基取代基,或碳链长度为 C3-16 的不饱和烃取代基,并具有一个或一个以上的多重化学键、
- R4 代表碳链长度为 C1-20 的烷基取代基,或碳链长度为 C3-20 的不饱和烃取代基,其特征为一个或一个以上的多重化学键、
- X 代表硝酸根(III)、硝酸根(V)、丙酸根、双氰基或十二烷基苯磺酸根阴离子、
在用于粘合刨花板的粘合树脂溶液中制备离子液体分散液,然后用已知方法将制备的树脂和离子液体分散液组合物涂抹到刨花上,从而继续刨花板的生产过程。
