The invention relates to the technical field of rearview mirrors, in particular to a hydrophobic rearview mirror and a preparation method thereof. The hydrophobic rearview mirror comprises at least one dielectric layer, at least one metal layer and at least one reflection increasing layer which are sequentially formed on a substrate. Wherein the reflection increasing layer comprises an outer side film layer, and the outer side film layer is selected from at least one of a ZTO film layer deposited by magnetron sputtering based on an MF power supply or a HiPIMS power supply and a ZnSnOx film layer deposited by magnetron sputtering based on the HiPIMS power supply. According to the hydrophobic rearview mirror, the hydrophobic performance can be effectively improved, and meanwhile the hydrophobic performance of the rearview mirror hardly declines after multiple times of friction.
本发明涉及后视镜技术领域,特别涉及一种疏水后视镜及其制备方法。其中,所述疏水后视镜包括在基板上依次形成的至少一层介质层、至少一层金属层和至少一层增反射层;其中,所述增反射层包括外侧膜层,所述外侧膜层选自基于MF电源或HiPIMS电源所磁控溅射沉积的ZTO膜层、基于HiPIMS电源所磁控溅射沉积的ZnSnOx膜层中的至少一种。本发明所提供的疏水后视镜可有效提高其疏水性能,同时在多次摩擦后其疏水性能几乎不存在衰退现象。
