Abstract
This invention describes a treatment for wood and other cellulosic materials for minimizing the net dimensional change in the wood and/or cellulosic material between cycles of shrinking and swelling. Cycles of shrinking and swelling compromise the integrity of cellulosic materials, including wood. The water-in-oil composition disclosed herein can be used as a treatment to reduce the magnitude of the dimensional change, thereby mitigating stress and reduce cracking.
Claims20
A composition comprising an emulsion having oil as the continuous phase and having water as the dispersed phase, wherein said emulsion further contains a first surfactant, and wherein the average particle size of the dispersed phase is less than about 100 nanometers.
A composition comprising an emulsion having a continuous oil phase and having an aqueous dispersed phase, wherein said emulsion further contains a first surfactant that functions as an emulsifier, and wherein the average particle size of the dispersed phase is less than about 100 nanometers.
A method for the treatment of cellulosic material, wherein said method comprises treating the cellulosic material with a composition, wherein said composition includes an emulsion having oil as the continuous phase and having water as the dispersed phase, and wherein said emulsion further includes an emulsifier, and wherein the average particle size of the dispersed phase is less than about 100 nanometers.
