Embodiment 1
[0021] A kind of double-layer laminated glass production process specifically described, comprises:
[0022] S1, glass treatment: grinding and polishing the glass surface, and cutting the glass, chamfering and grinding the edge of the film after cutting the glass, grinding one side of the glass plate to form smooth pits in the form of a matrix, and increasing its The contact surface with the glue.
[0023] S2, treatment of laminated glue: heat the silica gel block to melt it, and keep its temperature at all times to prevent it from solidifying, and vacuumize it during use to extract the air bubbles in it. The place where the silicone material is stored is kept at the same temperature as when it was heated.
[0024] S3, glass assembly: Prepare a piece of cut glass as the bottom glass, apply a sufficient amount of silicone material treated in S2 evenly on it, and then cover the upper glass plate. During the glass splicing process, it needs to be kept The two sides of the facin...
Embodiment 2
[0028] A kind of double-layer laminated glass production process specifically described, comprises:
[0029] S1, glass treatment: grinding and polishing the glass surface, and cutting the glass, chamfering and grinding the edge of the film after cutting the glass.
[0030] S2, treatment of glue: heat the silica gel block to make it melt, and keep its temperature at all times to prevent it from solidifying, and vacuumize it during use to extract the air bubbles therein.
[0031] S3, glass assembling: Prepare a piece of cut glass as the bottom glass, apply a sufficient amount of silicone material treated in S2 evenly on it, and then cover the upper glass plate.
[0032] S4, treatment of air bubbles: store the laminated glass after the treatment in S2 in a vacuum-pumping device for vacuum-pumping treatment.
[0033] S5, detection: the light transmittance detection of the laminated glass treated in S4.

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...
