In order to improve the waterproof and mildew resistance of electronic equipment, a superhydrophobic coating was prepared on a circuit board. First, hexadecyl trimethoxysilane was used to modify the nano silica and nano zinc oxide particles, and then the modified nanoparticles were mixed with the silica sol. Then the superhydrophobic coating was prepared on the surface of the printed circuit board by a spraying process. The preparation technology and physical and chemical properties of the coating were studied. The contact angle of the final sample can reach 169.47°, the sliding angle can reach 1.2°, it has good acid and alkali corrosion resistance, resistance to NaCl, self-cleaning performance and antimildew performance.
为提高电子设备的防水防霉性能，在电路板上制备了一种超疏水涂层。首先，用十六烷基三甲氧基硅烷对纳米二氧化硅和纳米氧化锌颗粒进行改性，然后将改性后的纳米颗粒与硅溶胶混合。接着通过喷涂工艺在印刷电路板表面制备超疏水涂层。研究了该涂层的制备工艺及其物理化学性能。最终样品的接触角可达169.47°，滑动角可达1.2°，具有良好的耐酸碱腐蚀性、耐NaCl性、自清洁性能和防霉性能。
