本发明属于玻璃技术领域,尤其涉及一种汽车后视镜用蓝镜及其制备方法,汽车后视镜用蓝镜包括热弯玻璃基片,所述热弯玻璃基片包括相对设置的凹面和凸面,所述凹面上依序叠层设置有形成复合膜的第一高折射率膜层、第一低折射率膜层、第二高折射率膜层、第二低折射率膜层和金属膜层,所述凸面呈蓝绿色。本发明的汽车后视镜用蓝镜,其优点是该热弯玻璃基片的凸面朝内,复合膜的膜面朝里,在环境耐久性方面得到提高,同时凸面呈蓝绿色,对光线柔和,可有效降低强光对驾驶员视线的干扰,起到有效的防炫目作用;并且热弯玻璃基片具有双曲率,从而可以获得大视野效果,不但功能好,且外形也更加美观。

    The invention belongs to the technical field of glass and particularly relates to a blue mirror for an automobile rearview mirror and a preparation method thereof. The blue mirror for the automobile rearview mirror comprises a hot bending glass substrate; the hot bending glass substrate comprises a concave surface and a convex surface which are arranged oppositely; the concave surface is sequentially provided with a first high refractive index film layer, a first low refractive index film layer, a second high refractive index film layer, a second low refractive index film layer and a metal film layer which are used for forming a composite film in a laminated mode; and the convex surface has a blue-green color. The blue mirror for the automobile rearview mirror has the advantages that the convex surface of the hot bending glass substrate is inward, and the film surface of the composite film is inward, so that the blue mirror is improved in the aspect of environmental durability; furthermore, the convex surface has the blue-green color, is soft to light and can effectively reduce the interference of glare to the sight line of a driver so as to achieve the effect of effectively preventing the driver from dazzling; and the hot bending glass substrate has double curvature, so that a wide view effect can be obtained. The blue mirror for the automobile rearview mirror has good functions and has more beautiful appearance.
