Description
Technical Field
One or more embodiments of the present disclosure relate to the technical field of laminated glass production processes, and in particular, to a double-layer laminated glass production process.
Background
The laminated glass is a composite glass product which is formed by two or more pieces of glass, wherein one or more layers of organic polymer intermediate films are sandwiched between the two or more pieces of glass, and the glass and the intermediate films are permanently bonded into a whole after special high-temperature prepressing (or vacuumizing) and high-temperature high-pressure processing.
After the laminated glass is used as safety glass and is crushed by impact, no sharp fragments are generated to hurt people like the common glass due to the bonding effect of a PVB film sandwiched between two pieces of common glass. Meanwhile, the PVB intermediate film has the performance of sound insulation and sunlight control, and becomes a novel building material with energy-saving and environment-friendly functions: the laminated glass can not only isolate the fitting noise of 1000 Hz-2000 Hz which can penetrate through the ordinary glass, but also can block more than 99% of ultraviolet rays and absorb heat in infrared spectrum. The laminated glass conforming to the performance of the novel building materials must play a great role in the use of safety glass.
When the laminated glass in the prior art is produced, the bubbles at the laminated part are difficult to realize in the laminated glass in the production process, and the using effect is difficult to realize, so that the requirements of the prior art cannot be met.

In view of the above, an object of one or more embodiments of the present disclosure is to provide a double laminated glass manufacturing process to solve the problems.
In view of the above, one or more embodiments of the present disclosure provide a double laminated glass manufacturing process, including: s1, glass treatment: grinding and polishing the surface of the glass, cutting the glass, and chamfering and grinding the edge of the film after cutting the glass;
s2, carrying out glue inclusion treatment: heating the silica gel block to melt the silica gel block, keeping the temperature of the silica gel block constantly to prevent the silica gel block from solidifying, and vacuumizing the silica gel block to extract bubbles in the silica gel block when the silica gel block is used;
s3, assembling glass: preparing a piece of glass from the cut glass as bottom glass, uniformly coating sufficient silica gel material treated in S2 on the glass, and covering the upper glass plate;
s4, bubble processing: the laminated glass after being processed in the step S2 is stored in a device capable of vacuumizing to be vacuumized;
s5, detecting: the laminated glass treated in S4 was subjected to light transmittance detection.
In S1, one surface of the glass plate is polished to form a matrix of pits with smooth surfaces, so that the contact surface between the glass plate and the sandwiched glue is increased.
The position where the silicone material is stored after completion of the evacuation in S2 is kept at the same temperature as that during heating.
In the process of splicing the glass in the S3, the extrusion effect of the glass is required to be kept on the two sides of the glass.
When the vacuum is pumped in the S4, the silicon gel material is kept heated to the softening temperature of the silicon gel material, so that the flowing-out effect of the bubbles is facilitated.
The upper and lower glass layers are also kept under a certain pressure to help discharge bubbles when the vacuum is drawn in the S4.
In S5, the environment is as dark as possible during the detection.
As can be seen from the above description, one or more embodiments of the present disclosure provide a double-layer laminated glass production process, in which bubbles are first removed from silica gel preliminarily, so that the possibility of bubbles appearing at the center of the silica gel during production is greatly reduced during use, and the silica gel is subjected to vacuum treatment under the condition of maintaining pressure during splicing and after splicing, so that the bubble removal effect during use is achieved.
