Omnidirectional reflection red glass

Abstract

The invention discloses omnidirectional reflection bright red glass which comprises a glass substrate (1), a first high-refractive-index dielectric layer (2), a second low-refractive-index dielectric layer (3), a third high-refractive-index dielectric layer (4) and a fourth low-refractive-index dielectric layer (5) are sequentially arranged on the bottom surface of the glass substrate from inside to outside, and a surface potential reduction layer (6) and a microstructure layer (7) are sequentially arranged on the top surface of the glass substrate; the first high-refractive-index dielectric layer and the third high-refractive-index dielectric layer are TiOXNY films; the second low-refractive-index layer and the fourth low-refractive-index layer are SiOXNY films; the prefabricated surface potential reduction layer is a surface self-assembly layer of dimethyl diallyl ammonium chloride and sodium polyvinyl benzene sulfonate in sequence; and the microstructure layer is a SiO2 layer which is in single-layer discrete distribution and has an inverted spherical segment microsphere structure. The invention has the advantages that the glass has the characteristics of bright color, uniform color, high transmittance under visible light wavelength, and small color change when observed by human eyes at different angles.

Description

technical field [0001] The invention relates to the technical field of structural red glass, in particular to an omnidirectional reflective red glass. Background technique [0002] Structural tinted glass has both good transmittance and color, and the color is adjustable and environmentally friendly, and never fades. Therefore, it is more and more used in the cover plates of thin-film solar cells, silicon-based solar cells, and flat collectors. Glass. Red has auspicious and festive meanings in Chinese traditional culture, and red glass is widely used in architecture and decoration. [0003] At present, there are mainly three types of red glass: 1. The red color obtained by coloring the glass body. Patent No. CN106116144 A "A Preparation Method for Red Borosilicate Glass". This patent obtains red borosilicate glass by preparing batch materials and melting at high temperature , Patent No. CN102858703 B "Red Glass and Preparation Method", this patent obtains red glass by addi...

Problems solved by technology

[0003] At present, there are mainly three types of red glass: 1. The red color obtained by coloring the glass body. Patent No. CN106116144 A "A Preparation Method for Red Borosilicate Glass". This patent obtains red borosilicate glass by preparing batch materials and melting at high temperature , Patent No. CN102858703 B "Red Glass and Preparation Method", this patent obtains red glass by adding colorants of copper oxide and neodymium oxide to the basic glass composition, the red glass obtained above belongs to the body absorption coloring, visible light region The transmittance is not high, and the color modulation steps are cumbersome; 2. The red color obtained by using the structure of dielectric layer-metal layer-dielectric layer, patent No. The glass substrate includes a first dielectric layer, a copper layer or a copper-nitrogen composite layer, a first protective layer and a second dielectric layer in order to obtain a rose-red glass. Patent No. CN210261565 U "A Red Low-E Coating Glass", The patent uses a glass substrate to include a first silicon nitride layer, a first nickel-chromium alloy layer, a silver layer, a second nickel-chromium alloy layer, a ceramic zinc oxide layer, a titanium oxide layer, and a second silicon nitride layer. The red glass obtained by the multilayer structure, the red glass obtained by the above structure cannot be directly used as a single piece of glass because the metal layer in the middle is easily oxidized, so it needs to be laminated and packaged, resulting in high cost and low transmittance of the glass component; 3. Using The multilayer thin film structure includes a reflector layer, at least one absorber layer and at least one outer dielectric layer to obtain the red color. Patent No. CN107340556 B "Omnidirectional High Chroma Red Structural Color", this patent uses multilayer interference films to form a reflective single Narrow-band visible light structure, although the structure has high chromaticity and good omnidirectionality, but the structure is too complex, which is not conducive to mass production, and this structure sacrifices the transmittance of visible light in order to pursue high chromaticity, so it cannot be used on a single cover glass use on
