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 anti-reflection layer and at least one reflection increasing layer which are formed on the opposite faces of the glass substrate respectively, and a third medium-refractive-index layer and a third high-refractive-index layer which are sequentially formed on the surface of the reflection increasing layer in a stacked mode. Wherein the reflection increasing layer comprises a middle refractive index layer, a high refractive index layer and a low refractive index layer which are sequentially laminated; the refractive indexes of the middle refractive index layer and the third middle refractive index layer are 1.60 to 2.30; the refractive indexes of the high refractive index layer and the third high refractive index layer are 2.30 to 2.72; and the refractive index of the low refractive index layer is 1.46 to 1.80. Images displayed/reflected by the semi-reflecting and semi-transmitting automobile inside rear-view mirror lens provided by the invention are free of ghosting and chromatic aberration.

    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相对面上的至少一层减反射层和至少一层增反射层,以及依次层叠形成在所述增反射层表面的第三中折射率层和第三高折射率层;其中,所述增反射层包括依次层叠形成的中折射率层、高折射率层和低折射率层;所述中折射率层和第三中折射率层的折射率为1.60~2.30;所述高折射率层和所述第三高折射率层的折射率为2.30~2.72;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所显示/反射影像无重影、无色差。
