Double-layer laminated glass production process

Abstract

One or more embodiments of the invention provide a double-layer laminated glass production process. The process comprises the following steps of: S1, treatment of glass, specifically, carrying out grinding and polishing treatment on the surface of the glass, cutting the glass, and carrying out chamfering and grinding on the edge of a film after cutting the glass; S2, treatment of laminated glue; S3, splicing the glass, specifically, preparing a piece of glass as bottom glass from the cut glass, and uniformly smearing a sufficient amount of a silica gel material treated in the step S2 on the bottom glass; S4, bubble treatment, specifically, storing the laminated glass treated in the step S2 in equipment capable of vacuumizing, and carrying out vacuumizing treatment on the laminated glass; and S5, detection. According to the method, firstly, bubbles are preliminarily removed from the silica gel, the possibility that bubbles appear in the center of the silica gel during production is greatly reduced during use; pressure is kept in the splicing process, and after splicing is completed, the glass is subjected to vacuum treatment under the condition that the pressure is kept, so that the bubble removing effect during use is achieved.

Description

technical field [0001] One or more embodiments of this specification relate to the technical field of laminated glass production technology, in particular to a double-layer laminated glass production process. Background technique [0002] Laminated glass is made of two or more pieces of glass with one or more layers of organic polymer intermediate film between them. A bonded composite glass product. [0003] As a kind of safety glass, when laminated glass is broken by impact, due to the bonding effect of the PVB film sandwiched between two pieces of ordinary glass, it will not produce sharp fragments to hurt people like ordinary glass after it is broken. At the same time, the sound insulation and sunlight control properties of its PVB interlayer film make it a new type of building material with energy-saving and environmental protection functions: the use of laminated glass can not only isolate the 1000 Hz-2000 Hz matching noise that can penetrate ordinary glass, And it ca...

Problems solved by technology

[0004] When the laminated glass in the prior art is produced, it is difficult to realize the air bubbles in the laminated part of the interior during the production process, and it is difficult to achieve the effect when it is used, so it cannot meet the needs of the prior art.
