Abstract

The invention relates to a preparation method of a photochromic vehicle window capable of stopping ultraviolet rays and a product and application of the photochromic vehicle window. The method includes the steps that a photochromic nanometer material capable of stopping the ultraviolet rays is prepared, wherein the general formula of the material is MaObXc, M, O, X, a, b and c are defined in the patent, the photochromic nanometer material is used, a photochromic nanometer material film adheres to the surface of a common vehicle window, or the photochromic nanometer material and a vehicle window material are mixed and then formed, so that the photochromic vehicle window is prepared. The prepared photochromic vehicle window can stop over 80% of the ultraviolet rays and can be changed into atransparent dark color under strong light illumination, and the transmitting rate is reduced; and the photochromic vehicle window can recover the colorless and transparent state without strong light illumination. The method has the beneficial effects that the technological process is simple, cost is low, the yield is large, the window is suitable for industrial production, and the practical prospects are good.

Description

technical field [0001] The invention relates to the field of intelligent color-changing materials, in particular to a preparation method of a photochromic vehicle window capable of blocking ultraviolet rays, a photochromic vehicle window and an application thereof. Background technique [0002] Photochromism refers to the chemical reaction of certain compound materials under the action of light of a certain wavelength and intensity, resulting in changes in the structure of the compound, causing the color of the compound to change, after the light is removed or irradiated by another wavelength and intensity of light , the color recovers or a new change occurs. Since the 1950s, when Hirshberg et al. reported the possibility of photochromic application in optical recording and storage, the performance and application of various new photochromic materials have been systematically studied and widely used in building window glass. , color-changing glasses lenses, vehicle window g...
