Description
Technical Field
The utility model relates to a chemically strengthened glass plate, a chemically strengthened glass assembly for laser welding and a laser welding composite glass plate, and belongs to the technical field of composite glass plates.
Background
The existing glass laser welding process has very severe requirements on glass properties, such as glass surface flatness, glass Center Tension (CT), etc., because these requirements often require that a layer (or multiple layers) of special adhesive material be coated (or other processes such as spraying/magnetron sputtering) on the glass surface in advance for protecting/improving the properties of the areas to be welded.
Taking the glass center tensile stress as an example: the center tensile stress of the chemically tempered glass is not too large, otherwise the glass cannot be welded, so that a layer (or multiple layers) of adhesive material capable of playing a role in protection/blocking needs to be coated on the area where laser welding is planned on the surface of the chemically tempered glass in advance, thereby weakening/preventing the chemical tempering effect of the area and reducing the center tensile stress of the glass.
However, when the existing common adhesive materials such as epoxy resin glue and polyurethane glue are used for coating the glass surface, laser cannot penetrate the materials to weld two pieces of glass together, so that the adhesive materials on the glass surface need to be cleaned before glass laser welding, and the properties such as flatness and transmittance of the cleaned glass surface need to be ensured, so that the requirements on the processing technology level are very strict.
Aiming at the problem that laser can fail when the existing adhesive material exists between the two transparent glass materials, a new glass assembly capable of being used for glass laser welding needs to be developed.
