Wax impregnation is an effective approach to improve wood water resistance. However, melted waxes require special equipment and cannot penetrate deep enough into wood. Recently, wax emulsions show excellent efficiency in wood modification. In this study, paraffin Pickering emulsion stabilized by low dispersed SiO₂ nanospheres was used to impregnate poplar wood. The microstructure and storage stability of the emulsion were evaluated. The dimensional stability, water uptake, wettability, and thermal stability of treated wood were also investigated. After homogenization, a milk-white oil-in-water (O/W) paraffin Pickering emulsion stabilized by the nano-SiO₂ (diameter of ~76 nm) was formed and demonstrated excellent storage stability. Paraffin Pickering emulsion could penetrate into the wood structure. The emulsion-treated wood was endowed with a moderate anti-swelling efficiency (ASE), high water resistance, and low wettability. Moreover, the addition of nano-SiO₂ could improve the thermal stability of the treated wood.

纳米SiO2稳定的石蜡采摘乳液设计用于木材浸渍。

蜡浸渍是提高木材耐水性的有效方法。但是，融化的蜡需要特殊的设备，并且不能深入到木材中。最近，蜡乳液在木材改性中显示出优异的效率。在这项研究中，由低分散的SiO ₂纳米球稳定的石蜡Pickering乳液用于浸渍杨木。评价乳液的微观结构和储存稳定性。还研究了经处理的木材的尺寸稳定性，吸水率，润湿性和热稳定性。均质后，通过纳米SiO ₂稳定的乳白色水包油（O / W）石蜡Pickering乳液（约76nm的直径）形成并显示出优异的储存稳定性。石蜡Pickering乳液可能会渗透到木材结构中。经乳液处理的木材具有适度的抗溶胀效率（ASE），高耐水性和低润湿性。此外，添加纳米SiO ₂可以改善处理后木材的热稳定性。
