The invention belongs to the technical field of surface treatment of automobile exterior trimming parts, and particularly relates to a radar-wave-permeable automobile exterior trimming part and a preparation method thereof. The automobile exterior trimming part comprises an exterior trimming part body and a radar-wave-permeable film layer structure located on the upper surface of the exterior trimming part body, and the radar-wave-permeable film layer structure sequentially comprises a first indium oxide film layer, a metal indium film layer and a second indium oxide film layer. According to the automobile exterior trimming part, the structure that the metal indium film layer is protected by the double indium oxide film layer is adopted, the white light penetrating effect of the automobile exterior trimming part is ensured, and the efficient radar wave penetrating function is achieved. The film layer structure realizes a high standard that radar wave bidirectional transmission attenuation is less than 3dB, and perfectly accords with the trend of intelligent and networking development of the current automobile industry.

    本发明属于汽车外饰件表面处理技术领域,具体涉及一种可透雷达波的汽车外饰件及其制备方法。所述汽车外饰件,包括外饰件本体以及位于外饰件本体上表面可透雷达波的膜层结构,所述可透雷达波的膜层结构依次包括第一氧化铟膜层、金属铟膜层和第二氧化铟膜层。本发明采用了双氧化铟膜层保护金属铟膜层的结构,不仅确保了汽车外饰件透白光的效果,还具备了高效的雷达波穿透功能。该膜层结构实现了雷达波双向透射衰减小于3dB的高标准,完美契合了当前汽车行业向智能化、网联化发展的趋势。
