The invention discloses a preparation method of vehicle window glass, which comprises the following steps: providing substrate glass, forming a color-changing area and a non-color-changing area on one surface of the substrate glass, and the thickness of the non-color-changing area is greater than that of the color-changing area; photochromic glass is attached to the color-changing area of the substrate glass through OCA glue, and the total thickness of the photochromic glass, the OCA glue and the color-changing area of the substrate glass is equal to the thickness of the non-color-changing area of the substrate glass; a gap between the photochromic glass and the non-color-changing area of the substrate glass is filled with a resin material, and the refractive index of the resin material is the same as or close to that of the substrate glass. The vehicle window glass prepared by the preparation method not only can play a role in adjusting light, but also is convenient for a driver to check rearview mirrors outside a vehicle. The invention further discloses the vehicle window glass.

    本发明公开了一种车窗玻璃的制备方法,包括:提供一衬底玻璃,所述衬底玻璃的一表面上形成有变色区域和非变色区域,所述非变色区域的厚度大于所述变色区域的厚度;将一光致变色玻璃通过OCA胶贴合于所述衬底玻璃的变色区域上,所述光致变色玻璃、OCA胶和所述衬底玻璃的变色区域的总厚度等于所述衬底玻璃的非变色区域的厚度;在所述光致变色玻璃与所述衬底玻璃的非变色区域之间的间隙中填充树脂材料,所述树脂材料的折射率与所述衬底玻璃的折射率相同或接近。该制备方法所制备的车窗玻璃既可起到调节光线作用,也方便驾驶员查看车外的后视镜。本发明还公开了上述车窗玻璃。
