Smart glass using nano silver conducting layer and manufacturing method of smart glass

Abstract

The invention discloses smart glass using a nano silver conducting layer and a manufacturing method the smart glass. The smart glass comprises, by weight percentage, 0.1-15 of conductive filler, 0.05-8% of film forming agent, 0.01-6% of conductivity adjusting agent and the balance of solvent. The method includes: welling mixing the materials to prepare conductive slurry; evenly coating the conductive slurry on glass base material, heating at 50-180 DEG C to cure the conductive slurry so as to form an even conducting film layer and obtain the conductive glass; guiding out a wiring circuit from the edge on one side of each of two pieces of conductive glass, adhering the four lateral edges of the conductive glass, allowing the conducting film layers to face each other and a hollow layer to be formed between the two conducting film layers, filling liquid crystal in the hollow layer under a vacuum condition, and sealing the filling opening to obtain the smart glass using the nano silver conducting layer.

Description

technical field [0001] The invention belongs to the field of glass manufacturing, and in particular relates to a dimming glass using a nano-silver conductive layer and a manufacturing method thereof. Background technique: [0002] Dimming glass is a special photoelectric glass product with a laminated structure that combines liquid crystal film into the middle of two layers of conductive glass and then glues it into one body. Control the transparent and opaque state of the glass by controlling the on and off of the current, which can be used for space partition, residential exterior settings, bathroom, toilet partition, privacy protection, projection screen, clear projection, in museums, exhibition halls, shopping malls , Bank anti-theft can also be applied. [0003] Switchable glass was invented and patented by researchers from Kent State University in the United States in the late 1980s. [0004] The main functional layers of dimming glass are the liquid crystal layer an...

AI Technical Summary

Problems solved by technology

[0005] 1. The sputtering deposition process must be in a vacuum environment, requiring expensive vacuum deposition equipment

[0006] 2. During the sputtering deposition process, only a small amount of target material is sputtered onto the substrate, and the rest is sputtered onto the chamber wall, resulting in a great waste of raw materials

[0007] 3. The high temperature of 300°C to 400°C is used in the sputtering deposition process, which requires a large energy consumption

[0008] 4. Metal oxides are relatively brittle, and the difficulty of processing will increase as the size becomes larger

[0009] 5. The switchable glass using metal oxide as the conductive layer is not suitable for super-sized switchable glass, and the maximum width is about 2m

[0010] 6. During the processing or use of the switchable glass prepared with metal oxide conductive film, the conductive coating will be broken or the resistivity will be increased due to the large shrinkage rate, which will greatly shorten the performance and service life of the finished switchable glass
