Wax formulations for lignocellulosic products, methods of their manufacture and products formed therefrom

摘要

Disclosed is a wax formulation comprising a wax; an emulsion stabilizing component; and a surface tension/interfacial tension reducing agent, wherein the surface tension/interfacial tension reducing agent comprises an alkylphenol alkoxylate, a C2-C3 alkoxylated, substantially symmetrical acetylenic diol having 6 to about 100 carbon atoms, and a combination of a C2-C3 alkoxylated, substantially symmetrical acetylenic diol having 6 to about 100 carbon atoms and a siloxane. The formulation can further comprise water. Also disclosed is a method for making a wax emulsion, comprising: combining an emulsifiable wax, an aqueous medium, and an emulsion stabilizer to form a mixture; agitating the mixture to form an emulsion; and then adding a surface tension/interfacial tension reducing agent after the emulsion is formed, wherein the surface tension/interfacial tension reducing agent comprises an alkylphenol alkoxylate, a C2-C3 alkoxylated, substantially symmetrical acetylenic diol having 6 to about 100 carbon atoms, a combination of a C2-C3 alkoxylated, and substantially symmetrical acetylenic diol having 6 to about 100 carbon atoms and a siloxane. Further disclosed is a lignocellulosic composite comprising a lignocellulosic material and the disclosed wax emulsion.
