Problems solved by technology

The performance of fire-resistant interlayer materials is different, and it is difficult to distinguish the pros and cons of fire resistance limit, weather resistance and other properties from the appearance, and it is easy to appear counterfeit products
If the general anti-counterfeiting method is used, it is difficult to play a good role, so a new method is needed to provide anti-counterfeiting capabilities for composite fire-resistant glass

Abstract

The invention provides fluorescent composite fireproof glass and a preparation method thereof. The preparation method comprises the following steps: a) mixing a carbon-based precursor, a nitrogen-containing substance, a silane coupling agent and water, carrying out a hydrothermal reaction, and cooling to obtain a nitrogen-hybridized blue light carbon-based molecular solution; b) mixing alkaline silica sol and glycerol, concentrating to remove water of which the mass is the same as that of the glycerol, then sequentially adding the nitrogen-hybridized blue-light carbon-based molecular solution obtained in the step a) and a potassium hydroxide aqueous solution, reacting, and then stirring and cooling under a vacuum condition to obtain groutable intermediate liquid; and c) injecting the groutable intermediate liquid obtained in the step b) into a cavity between glass interlayers, and curing to obtain the fluorescent composite fireproof glass. Compared with the prior art, the preparation method provided by the invention adopts specific process steps to realize better overall interaction, and the prepared fluorescent composite fireproof glass has a body anti-counterfeiting function and is strong in concealment, strong in ultraviolet shielding property and good in thermal stability.

Description

technical field [0001] The invention relates to the technical field of luminescent fireproof materials, and more specifically, relates to a fluorescent composite fireproof glass and a preparation method thereof. Background technique [0002] As a global problem, counterfeit and shoddy products have caused serious adverse effects on the economy and safety of governments, industries and consumers. Therefore, the development of reliable and safe anti-counterfeiting technology has been widely concerned. In the past decade, a variety of anti-counterfeiting technologies have emerged, such as plasma-based anti-counterfeiting labels, magnetic response technology, holographic anti-counterfeiting technology, and optical anti-counterfeiting technology. Compared with other anti-counterfeiting technologies, the cost of fluorescent anti-counterfeiting is lower, and the preparation and operation are relatively simple, and the concealment is better, so it has attracted more and more attent...
