Self-cleaning, antifogging and thermal-insulation coating glass and preparation method thereof

The invention discloses self-cleaning, antifogging and thermal-insulation coating glass and a preparation method thereof. The glass comprises a basal plate, wherein the surface of the basal plate is provided with a composite film layer, the composite film layer successively comprises an inner layer, an intermediate layer and an outer layer from inside to outside, the inner layer is a silicon dioxide layer, the intermediate layer is a silicon dioxide and diamond-like layer, and the outer layer is a fluorination diamond-like layer. The glass of the invention has a good self-cleaning, antifoggingand thermal-insulation function, and the binding strength among the film layers is high. 本发明公开了种自洁、防雾、隔热镀膜玻璃及其制备方法，玻璃包括基板，基板的表面上设有复合膜层，复合膜层由内之外依序包括内层、中间层和外层，内层为二氧化硅层，中间层为二氧化硅+类金刚石层，外层为氟化类金刚石层。本发明的玻璃具有良好的自洁、防雾和隔热功能，同时膜层间的结合强度高。
