Problems solved by technology

[0003] Traditional stained glass generally adopts the process of online preparation. Taking the method of chemical preparation and spray printing as an example, the products produced by this method have a single color, and one color corresponds to one process.
If you want to change the color of the product, you need to change the preparation conditions, the process is extremely cumbersome, and the cost of discoloration is high
For example, it is necessary to replace the glass melt composition of the entire molten pool and to clean the molten pool fully and thoroughly (the volume of the molten pool is large); or to change the raw material of the organic coating sprayed or printed on the glass surface. The above methods are time-consuming, laborious and expensive. Very high, does not meet the requirements of modern new product preparation
And the products prepared by this type of method produce a lot of waste materials, some of which are toxic and unfriendly to the environment
In addition, this preparation process using the color of the material itself, the product performance is greatly affected by the uniformity of the material, and the color of the product is unstable

Abstract

The invention provides colored glass and a preparation method thereof, belonging to the technical field of coating. The stained glass of the present invention comprises a glass substrate, a laminated structure and a Ti alloy layer stacked on the surface of the glass substrate, the laminated structure includes alternately laminated layers A and B; the layer A is a SiC or NiO layer; the layer A is a layer of SiC or NiO; B layer is AlN, GaN, ZrO 2 or Nb 2 o 5 layer; the A layer is in contact with the glass substrate, and the B layer is in contact with the Ti alloy layer. The present invention utilizes the different materials of the A layer and the B layer, and there is a difference in refractive index between the layers to make the glass appear colored, and the color of the glass is controlled by adjusting the thickness of the A layer and the B layer in the laminated structure. The Ti alloy layer has a high reflectivity, which can make Stained glass is bright in color and plays a certain protective and anti-corrosion role. The results of the examples show that the colored glass of the present invention is bright in color and rich in color series, the surface color does not change after tempering, and the color of the product is stable.

Description

technical field [0001] The invention relates to the technical field of coating, in particular to colored glass and a preparation method thereof. Background technique [0002] Glass is the most common material in our daily life and is closely related to people's production activities. With the development of modern science and technology and glass technology and the improvement of people's living standards, the function of architectural glass is no longer just to meet the lighting requirements, but to It has the characteristics of light adjustment, thermal insulation, bulletproof, anti-theft, fire prevention, radiation protection, electromagnetic interference prevention, art decoration and so on. [0003] Traditional stained glass generally adopts the process of online preparation.
