The invention relates to the technical field of automobile parts, in particular to a semi-reflecting and semi-transmitting automobile inside rear-view mirror lens and a preparation method thereof. The semi-reflecting and semi-transmitting automobile inside rear-view mirror lens comprises a glass substrate, at least one antireflection layer and at least one reflection increasing layer which are formed on the two faces of the glass substrate respectively, and a third high-refractive-index layer formed on the surface of the reflection increasing layer. Wherein the reflection increasing layer comprises a high-refractive-index layer and a low-refractive-index layer, the high-refractive-index layer and the low-refractive-index layer are sequentially formed in a stacked mode, and the third high-refractive-index layer is formed on the surface of the low-refractive-index layer; the refractive indexes of the high refractive index layer and the third high refractive index layer are 2.20 to 2.72; and the refractive index of the low refractive index layer is 1.46 to 1.80. According to the semi-reflecting and semi-transmitting automobile inside rear-view mirror lens, the visible light reflectivity of a rear-view mirror can be effectively improved, and meanwhile image color cast can be avoided.
本发明涉及汽车零部件技术领域,特别涉及一种半反半透汽车内后视镜镜片及其制备方法。其中,所述半反半透汽车内后视镜镜片包括玻璃基板,分别形成在所述玻璃基板两面的至少一层减反射层和至少一层增反射层,以及形成在所述增反射层表面的第三高折射率层;其中,所述增反射层包括依次层叠形成的高折射率层和低折射率层,所述第三高折射率层形成在所述低折射率层的表面;所述高折射率层和所述第三高折射率层的折射率为2.20~2.72;所述低折射率层的折射率为1.46~1.80。本发明所提供的半反半透汽车内后视镜镜片可有效提高后视镜可见光反射率的同时,可避免影像偏色。
