초록
Paraffin wax treated wood has high dimensional stability against water. However, due to the flammable property of paraffin wax, it has a problem that it is weak against fire. In or- der to have flame retardant properties in paraffin wax-treated wood, a Pickering emulsion was prepared using a wood flame retardant and paraffin wax, and the combustibility and dimen- sional stability of the treated wood was investigated, and the following conclusions were reached. A stabilized paraffin Pickering emulsion that does not phase separate from water can be prepared by adding 5 wt.% paraffin wax to the nano-silica dispersion solution and homoge- nizing it. Wood impregnated with a paraffin Pickering emulsion prepared from a nano-silica dispersion containing a flame retardant component can expect flame retardant properties almost the same as wood impregnated with only flame retardant solution. The effect of improving the dimensional stability of wood was not obtained by the paraffin Pickering emulsion im- pregnation, and in order to increase the dimensional stability in addition to flame retardant property, it is necessary to develop a Pickering emulsion manufacturing technology capable of increasing the amount of paraffin wax.
Abstract
Paraffin wax treated wood has high dimensional stability against water. However, due to the flammable property of paraffin wax, it has a problem that it is weak against fire.

A stabilized paraffin Pickering emulsion that does not phase separate from water can be prepared by adding 5 wt.% paraffin wax to the nano-silica dispersion solution and homoge- nizing it. Wood impregnated with a paraffin Pickering emulsion prepared from a nano-silica dispersion containing a flame retardant component can expect flame retardant properties almost the same as wood impregnated with only flame retardant solution. The effect of improving the dimensional stability of wood was not obtained by the paraffin Pickering emulsion im- pregnation, and in order to increase the dimensional stability in addition to flame retardant property, it is necessary to develop a Pickering emulsion manufacturing technology capable of increasing the amount of paraffin wax.
