As one of the most sustainable resources, wood has been widely used in the fields of construction, decoration, flooring and furniture. However, the micron-scale porous structure of wood makes it have strong moisture absorption capacity and is susceptible to bacterial adhesion. In order to expand its utility in more applications of wood products, it is necessary to make the wood have a certain antibacterial and waterproof properties. This study demonstrates a method of using hexadecyltrimethoxysilane and nano-titanium dioxide to prepare antibacterial and waterproof coating and apply it to wood surfaces. Studies have shown that this kind of wood coated with an antibacterial waterproof coating has excellent antibacterial properties (antibacterial rate as high as 99%) and waterproof properties, it can still maintain a water contact angle of nearly 80° after stirring in water for 10 minutes. In addition, this antibacterial and waterproof coating does not cause a major change in the color of the wood, and at the same time increase the tensile strength and hardness to a certain extent. The above-mentioned properties of this antibacterial and waterproof coating provide a new idea for the preparation of wood coatings.

十六烷基三甲氧基硅烷与纳米二氧化钛制备抗菌防水涂料对木材性能的影响

作为最具可持续性的资源之一，木材已广泛应用于建筑、装饰、地板和家具等领域。然而，木材的微米级多孔结构使其具有很强的吸湿能力，并且容易受到细菌的粘附。为了扩大其在木制品的更多应用中的用途，必须使木材具有一定的抗菌和防水性能。本研究展示了一种使用十六烷基三甲氧基硅烷和纳米二氧化钛制备抗菌防水涂料并将其应用于木材表面的方法。研究表明，这种涂有抗菌防水涂料的木材具有优良的抗菌性能（抗菌率高达99%）和防水性能，在水中搅拌10分钟后仍能保持近80°的水接触角。此外，这种抗菌防水涂层不会引起木材颜色的重大变化，同时在一定程度上增加了抗拉强度和硬度。这种抗菌防水涂料的上述性能为木器涂料的制备提供了新思路。
