Problems solved by technology

[0002] At present, laminated glass has been widely used in the fields of construction and automobiles, but it has not been practically applied in electronic equipment. Some researchers have proposed to apply laminated glass to electronic equipment casings, but its thickness is much larger than that of glass casings on the market. Thickness, and there are serious bubble problems, it is impossible to apply this technology to the actual production field
Therefore, the existing research on laminated glass still needs to be improved.

Embodiment 1

[0046] In this embodiment, two 0.25mm thick 3D glass pieces (inner glass piece and outer glass piece) bent on four sides are used, and the cross-sectional structure diagram can refer to Figure 4 ), a PVB film with a thickness of 0.075mm is subjected to a double-layer 3D composite process.

[0047] The production process is as follows: ① Slice the 0.25mm thick inner and outer glass, CNC (numerical control machine tool) processing, hot bending, polishing, edge sweeping, chemical strengthening and other processes, and process the inner glass and outer glass with 3D structure ②Put the above-mentioned outer glass parts into the positioning jig first, then put the laser-cut PVB film, and finally put the inner glass parts. The specific positioning method can be realized by means of jigs or CCD image sensors. ③Put the above products into a vacuum bag, and after sealing, vacuumize at room temperature for 60 minutes, then put it in a 110°C oven for 60 minutes to completely discharge th...

Embodiment 2

[0049] In this embodiment, three 2.5D glass pieces (upper glass piece, middle glass piece and lower glass piece) with a thickness of 0.4mm, 0.15mm (TFT display screen substrate glass, referred to as TFT glass) and 0.25mm respectively are used. A PVB film with a thickness of 0.025mm is subjected to a three-layer 2.5D composite process.

[0050] The production process is as follows: ① The upper, middle and lower glass of 0.4mm, 0.15mm (TFT glass), and 0.25mm thick are respectively sliced, CNC processed, polished, edge-swept, and chemically strengthened to process a 2.5D structure. The upper, middle and lower glass parts; ②Put the above lower glass parts into the jig first, then put in the laser-cut PVB film, and then put in the middle glass part, PVB film and upper glass part in turn. The specific positioning method can be adopted Fixtures, CCD and other ways to achieve. ③Put the above products into a vacuum bag, and after sealing, vacuumize at room temperature for 30 minutes, ...

Embodiment 3

[0052] In this embodiment, three 2.5D glass pieces (upper glass piece, middle glass piece and lower glass piece) with a thickness of 0.25 mm are used, and two PVB films with a thickness of 0.05 mm are used for a three-layer 2.5D composite process.

[0053] The manufacturing process is as follows: ① The upper, middle and lower glass parts with a thickness of 0.25mm are respectively sliced, CNC processed, polished, edge-swept, and chemically strengthened to process the upper, middle and lower glass parts with a 2.5D structure ;② Put the lower glass part into the jig first, then put the laser-cut PVB film, and then put the middle glass part, PVB film and upper glass part in turn. The specific positioning method can be realized by means of jig, CCD, etc. . ③Put the above products into a vacuum bag, and after sealing, vacuumize at room temperature for 30 minutes, then put it in a 100°C oven for 40 minutes to completely discharge the air in the bag. ④ Open the bag of the product th...

Abstract

The invention provides laminated glass and its preparation method and application. The laminated glass comprises at least two glass parts and at least one organic film, and the organic film is arranged between two adjacent glass parts, wherein the glass The thickness of the piece is 0.1-0.5 mm, and the thickness of the organic film is 25-100 microns. Therefore, the thickness of the glass parts and the organic film in the laminated glass is appropriate, not only the appearance is beautiful, the optical performance is good, but also has excellent mechanical properties, good drop resistance performance, no glass splash when broken, good safety , and can be used for housings of electronic equipment, and can be effectively applied to actual production fields.

Description

technical field [0001] The invention relates to the technical field of electronic equipment, in particular to laminated glass and its preparation method and application. Background technique [0002] At present, laminated glass has been widely used in the fields of construction and automobiles, but it has not been practically applied in electronic equipment. Some researchers have proposed to apply laminated glass to electronic equipment casings, but its thickness is much larger than that of glass casings on the market. thickness, and there are serious bubble problems, it is impossible to apply this technology to the actual production field. Therefore, the existing research on laminated glass still needs to be improved. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. Therefore, an object of the present invention is to provide a method for preparing laminated glass. The la...
