为了克服石蜡乳液在木材功能性改良方面的不足，本研究构建以硅烷改性纳米SiO2包覆石蜡液滴、剥离状蒙脱土片层三维网络结构协同稳定的水包油型石蜡基Pickering乳液复合体系，制备低粒径、高稳定性、多功能的木材改性剂。研究石蜡基Pickering乳液组分在不同处理工艺条件下在木材中的渗透规律以及乳液体系在渗透和后期干燥过程中的破乳机理，并通过调节浸渍和干燥工艺参数对破乳过程进行调控，从而实现乳液组分在木材构造中的合理分布和相互作用。考察处理材的物理力学性能、动态粘弹性、耐腐性、阻燃性、耐老化性等各项性能，并通过考察处理材的介电特性和水分吸附特性，研究乳液处理对木材中羟基的影响规律，从而构建相关模型解释其性能影响机理。该研究将前沿的乳液分散理论与技术应用于木材功能性改良领域，将指导乳液型木材改性理论体系的建立，进而推动新型多功能木材改性剂的技术开发。

In order to overcome the shortcomings of paraffin wax emulsions in functional modification of wood, a compound system of oil in water (O/W) paraffin wax based Pickering emulsion stabilized by silane-modified nano SiO2 to envelop paraffin wax droplets and exfoliated montmorillonite (MMT) layers to form 3-dimensional network between those droplets is proposed to build up to serve as a small particle sized, highly stable and multifunctional wood modifying agent. The penetration of these emulsions in wood under various impregnation process parameters as well as the breaking mechanism of the emulsions during penetration and followed drying processes will be studied. By changing the impregnation and drying process parameters, the emulsion breaking process was controlled to fulfill a reasonable distribution and interaction of the emulsion ingredients in wood structure. Then the physical and mechanical properties, dynamic viscoelasticity, decay resistance, fire resistance, and anti-weathering properties are investigated. The dielectric properties and moisture adsorption behavior will also be investigated to study the influence of emulsion treatment on hydroxyl groups in wood, based on which some models can be developed to explain the mechanism of properties’ change. This study applies the state-of-art emulsion dispersion theory and technologies in the region of wood functional modification, which will initiate the build-up of the theoretical system on wood modification by using emulsions, and further facilitate the development of innovative multi-functional wood modifying agents.
