Problems solved by technology

It affects both sight and safety, let alone driving for a long time
The disadvantage of the above is that the best solar film can't do much, and it needs to be operated by hand when using it, which is extremely inconvenient. It is necessary to improve it

Embodiment

[0008] A color-changing glass for automobiles, which is made by adding silver and halogen compounds and traces of copper oxide to ordinary glass raw materials. Copper oxide is the catalyst. The principle of color-changing glass mainly depends on a special chemical reaction between silver and halogen compounds and trace amounts of copper oxide and ultraviolet rays. Color-changing glass contains silver halide molecules, and silver halide decomposes when exposed to light. When there is no ultraviolet radiation, visible light can penetrate these molecules, and visible light is a general component of artificial light sources. But when exposed to the ultraviolet rays of sunlight, these molecules go through a chemical process that changes their shape -- the silver halide in them breaks down to produce silver and halogens in the form of many, many black particles of silver , evenly distributed in the glass to absorb part of the visible light, so the glass appears dim and blocks the p...

Abstract

The invention discloses automotive color-changing glass. The automotive color-changing glass is prepared by adding a compound of silver and halogen and trace copper oxide into a common glass raw material, wherein the copper oxide is a catalyst. The principle of the color-changing glass mainly depends on a special chemical reaction between the compound of the silver and the halogen as well and the trance copper oxide and ultraviolet rays. When the color-changing glass is exposed in the ultraviolet rays of sunshine, silver halide in the color-changing glass decomposes to produce the silver and the halogen and absorbs part of the visible light, so that the glass looks dim, namely the color darkens. When the color-changing glass leaves the radiation of the ultraviolet rays, corresponding chemical inverse change happens and molecules are recovered to original structure rapidly, so the glass changes light until colorless and transparent.

Description

technical field [0001] The invention relates to a color-changing glass product for automobiles and a preparation method thereof, in particular to a color-changing glass product for automobiles based on silver bromide, which is a compound of silver atoms and halogens added to ordinary glass raw materials, and a small amount of copper oxide. The preparation method is used for automobiles to prevent strong ultraviolet radiation and the like. Background technique [0002] Existing automotive glass, due to its poor light-shielding performance, when the car is placed outdoors, especially under strong ultraviolet radiation for a longer period of time and then enters the car, the temperature inside the car is very high due to the ultraviolet radiation, and the car interior skin is even It is very hot, and it takes a long time to cool even with the windows open and the air conditioner turned on. And when driving when the ultraviolet rays are very strong, the eyes are very uncomforta...
