Description

A type of colored glass and its laminated products Technical Field

[0001] This utility model relates to a colorful glass and its laminated products, belonging to the field of glass technology. Background Technology

[0002] In the construction industry, consumers and designers are increasingly demanding personalized and aesthetically pleasing designs for building exteriors and interior spaces. Iridescent glass, with its unique optical effects, can display dazzling colors under different lighting and viewing angles, adding a unique charm to buildings. Whether it's a modern office building whose facade uses stained glass to create a highly technological and fashionable appearance, standing out against the city skyline; or a high-end residential project where stained glass is applied to balcony railings and interior partitions to create a warm and artistic living space. According to market research data, the global demand for stained glass in the architectural decoration market has grown at an annual rate of 15%-20% over the past five years. Especially in emerging economies, with accelerated urbanization, the demand for stained glass in newly constructed buildings has seen explosive growth. It is expected that in the coming years, the architectural decoration market will remain one of the main application areas for stained glass, and the demand is expected to continue to expand.

[0003] Currently, traditional glass on the market is relatively monotonous in appearance, mainly consisting of transparent or single-color glass, which fails to meet the diverse and personalized aesthetic demands of modern society. With the development of industries such as architectural decoration and art display, the requirements for the decorative and aesthetic qualities of glass are increasing. Although existing processes such as screen printing and digital printing can print colored inks or pigments onto the surface of a nano-optical coating layer to form various patterns and colors, achieving a certain level of color, the color effects are relatively fixed, lacking dynamic changes and a sense of depth, and also have shortcomings in optical and mechanical properties. Therefore, there is an urgent need for a type of glass and its laminated products that can both display rich and vibrant colors and possess excellent performance. Summary of the Invention

[0004] The purpose of this invention is to provide a colorful glass and its laminated product to solve the above-mentioned problems.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A colorful glass includes a glass substrate and a coating applied to the glass substrate; the coating comprises, from the inside out, a first dielectric layer Nb2O5 layer, a second dielectric layer SiO2 layer, a third dielectric layer Nb2O5 layer, a fourth dielectric layer SiO2 layer, and a fifth dielectric layer Nb2O5 layer.

[0007] By controlling the power supply to control the thickness of the high-refractive-index layer and the low-refractive-index layer, a new coating layer system is formed. By controlling the thickness of the dielectric layer, different color changes are created, allowing the glass to have different dazzling effects when viewed from different angles.

[0008] A further improvement to the technical solution of this utility model is that the color of the iridescent glass is iridescent blue, and the thickness of each film layer is 57nm for the first dielectric layer Nb2O5 layer, 80nm for the second dielectric layer SiO2 layer, 35nm for the third dielectric layer Nb2O5 layer, 60nm for the fourth dielectric layer SiO2 layer, and 46nm for the fifth dielectric layer Nb2O5 layer.

[0009] A further improvement to the technical solution of this utility model is that the color of the iridescent glass is iridescent orange, and it also includes a sixth dielectric layer, SiO2 layer; the thickness of each film layer is 80nm for the first dielectric layer Nb2O5 layer, 120nm for the second dielectric layer SiO2 layer, 90nm for the third dielectric layer Nb2O5 layer, 80nm for the fourth dielectric layer SiO2 layer, 75nm for the fifth dielectric layer Nb2O5 layer, and 49nm for the sixth dielectric layer SiO2 layer.

[0010] A further improvement to the technical solution of this utility model is that the color of the iridescent glass is iridescent orange, and it also includes a sixth dielectric layer SiO2 layer and a seventh dielectric layer Nb2O5 layer; the thickness of each layer is 64nm for the first dielectric layer Nb2O5 layer, 94nm for the second dielectric layer SiO2 layer, 71nm for the third dielectric layer Nb2O5 layer, 21nm for the fourth dielectric layer SiO2 layer, 54nm for the fifth dielectric layer Nb2O5 layer, 140nm for the sixth dielectric layer SiO2 layer, and 42nm for the seventh dielectric layer Nb2O5 layer.

[0011] A laminated article using the aforementioned stained glass includes two pieces of glass and an intermediate layer sandwiched between the two pieces of glass; at least one of the two pieces of glass is selected from the aforementioned stained glass, and the coating of the stained glass is located on the side facing the intermediate layer.

[0012] A further improvement to the above-mentioned technical solution of this utility model is that the intermediate layer can be polyvinyl acetate or reinforced polyvinyl butyral.

[0013] Due to the adoption of the above technical solution, the technical effects achieved by this utility model are as follows:

[0014] This invention relates to iridescent glass and its laminated products. By rationally designing the thickness of each film layer, especially the geometric and optical thicknesses of the media layers with different refractive indices, the iridescent glass reflects and refracts a variety of colors, adding a lively and dynamic atmosphere to the space. Whether used for building facades, interior partitions, or decorative items, it can become a visual focal point, making the space more attractive and artistic. Furthermore, its laminated glass products maintain good safety functions while ensuring the physical and chemical properties of the glass facilitate subsequent processing.
