Description

UV blocking and blue light anti-corrosion coatings, glass, and laminated glass (Related Application) The present application claims priority to a Chinese patent application filed with the Chinese Intellectual Property Office, the filing date being December 15, 2020, the application number being 202011469860.1, and the title of the invention being 'UV-blocking blue light-blocking coating liquid, glass and method for manufacturing the same', and the contents of the prior application are incorporated by reference into the present application. The present invention relates to the field of surface coating application technology, particularly to functional coatings applied to glass surfaces, and specifically provides a UV-blocking blue light-blocking coating solution, UV-blocking blue light-blocking glass, and laminated glass, and simultaneously provides UV-blocking blue light-blocking laminated glass capable of dimming or emitting light. Through surface coating application technology, functional coatings can be formed on the surface of a substrate to satisfy requirements such as infrared blocking, ultraviolet blocking, hydrophobicity, and anti-fogging. Among these, ultraviolet blocking coatings can significantly reduce the transmittance of ultraviolet rays, thereby reducing the harm that ultraviolet rays cause to human health and preventing the aging and fading of automotive and residential interiors in a short period of time. Forming an ultraviolet blocking coating on the surface of a glass substrate is already a relatively mature technology. For example, Japanese patents JP2009184882A, JP201318934345A and Chinese patents CN102892851A, CN103347833A, CN111819160A all disclose that an ultraviolet blocking coating is formed by applying an ultraviolet blocking solution to the surface of a glass substrate, and that it possesses relatively good ultraviolet blocking ability and mechanical durability such as relatively high hardness and wear resistance. In the visible light spectrum, light with a wavelength range of 400nm to 500nm is generally defined as blue light. Among these, short-wave blue light with a wavelength of 400nm to 420nm has relatively high energy and can cause harm to the retina, such as visual fatigue, glare, and macular lesions; therefore, the transmittance of short-wave blue light must be reduced. Chinese patent CN109455945A discloses reflective anti-blue light glass and a method for manufacturing the same, comprising a glass substrate and an anti-blue light coating. The anti-blue light coating is a coating liquid with a reflective function, and the blue light reflectance at 400-450nm is 50%. It is mainly applied to electronic products, but its wear resistance results cannot satisfy the performance requirements for surface coatings of automotive glass. Additionally, Chinese patent CN11101457A discloses a glass structure comprising a pair of glass plates, a light source disposed between the pair of glass plates, and an ultraviolet absorption layer disposed between the light source and one glass plate, wherein the maximum transmittance of the ultraviolet absorption layer in the wavelength range of 370 nm or more and 400 nm or less is 10% or less, the maximum transmittance in the wavelength range greater than 400 nm and 420 nm or less is 50% or more, and if the maximum transmittance in the wavelength range greater than 400 nm and 420 nm or less is less than 50%, the glass structure appears colored when illuminated by sunlight. The technical problem that the present invention aims to solve is to address the disadvantages of existing technologies, such as the fact that blue light blocking coatings and UV-absorbing layers cannot simultaneously satisfy both UV blocking and blue light blocking. It provides a UV-blocking blue light blocking liquid, UV-blocking blue light blocking glass formed by applying the UV-blocking blue light blocking liquid, a method for manufacturing the UV-blocking blue light blocking glass, and simultaneously provides a UV-blocking blue light blocking laminated glass capable of dimming or emitting light. The technical solution adopted by the present invention to solve the technical problem is as follows. A UV-blocking blue light-blocking coating solution is used to form a UV-blocking blue light-blocking coating on the surface of a substrate, and the UV-blocking blue light-blocking coating solution comprises a silica sol and a chelating agent, and The silica sol comprises, in mass percentage, 15% to 35% silicate, 30% to 60% first solvent, 5% to 15% first coupling agent, 0.01% to 1% first catalyst, and 10% to 30% deionized water, and The chelating agent is characterized by comprising, in mass percentage, 1% to 15% UV absorber, 1% to 15% blue-light absorber, 40% to 60% second solvent, 0.01% to 1% second catalyst, and 10% to 30% second coupling agent. Preferably, 5 to 20 percent of a chelating agent is added per silica sol according to mass percentage. Preferably, the silicate is selecte
