Embodiment 1

[0036] Such as Figure 5-9 As shown, the present invention also provides a method for making an explosion-proof panel, comprising:

[0037] providing an upper pane 12 of a first size;

[0038] Coating a film layer 13 on the upper surface of the upper glass 12 of the first size;

[0039] Grinding 0.5-2 mm around the upper layer glass 12 of the first size to become the upper layer glass 12 of the second size;

[0040] providing lower pane 10 of a second size;

[0041] The upper glass 12 of the second size and the lower glass 10 of the second size are bonded together using the PVB film 11 .

[0042] The present invention increases the area of ​​the upper layer glass 12, and then grinds off the redundant part of the upper layer glass 12 to remove the part around the upper layer glass 12 and the lower surface around the coating layer 13, so as to ensure that the PVB film 11 will not stick to the redundant film layer 13 In addition, air bubbles are avoided between the upper glas...

Embodiment 2

[0049] This embodiment also provides an explosion-proof panel, comprising a lower glass 10, a PVB film 11 and an upper glass 12 that are stacked, the upper surface of the upper glass 12 has a film layer 13, and there is no film between the PVB film 11 and the upper glass 12 Layer 13. And there is no film layer 13 around the upper layer of glass 12 and at the chamfer of the upper layer of glass 12 . To prevent the PVB film 11 from being bonded to the upper layer of glass 12, there is a redundant film layer 13 in the middle, so that there are air bubbles in the explosion-proof panel.

[0050] The film layer includes one or more of AG film layer, AR film layer and AF film layer. Among them, the AG film layer is an anti-glare film, which changes the reflective surface of the original glass into a matte surface by chemical etching or spraying, and changes the roughness of the glass surface, thereby making the surface have a matte effect. When the external light is reflected, diff...

Abstract

The invention discloses a manufacturing method of an explosion-proof panel and the explosion-proof panel, and the manufacturing method of the explosion-proof panel comprises the following steps: providing upper-layer glass with a first size; plating a film layer on the upper surface of the upper-layer glass with the first size; polishing the periphery of the upper-layer glass with the first size by 0.5-2 mm to form upper-layer glass with a second size; providing an underlying glass of a second size; and laminating the upper-layer glass with the second size and the lower-layer glass with the second size by using a PVB film. According to the invention, the area of the upper-layer glass is increased, and the redundant part of the upper-layer glass is ground off so that the parts of the film layer wound and plated on the periphery and the lower surface of the upper layer glass can be ground off, thereby ensuring that the PVB film cannot be adhered to the redundant film layer, and avoidingbubbles generated between the upper-layer glass and the PVB film during adhesion.

Description

technical field [0001] The invention relates to the technical field of explosion-proof panels, in particular to a method for manufacturing an explosion-proof panel and the explosion-proof panel. Background technique [0002] Explosion-proof panel is a kind of panel that can prevent violent impact. It is a special panel made by machine processing with special additives and interlayer in the middle. Due to its high safety performance, it is now widely used, such as the central control panel of automobiles. There are mainly two types of explosion-proof panels. One is to use glass + explosion-proof film or PMMA as the cover, but this method is easy to cause surface scratches and affect user experience. another such as Figure 1~4 As shown, it is made by bonding the lower glass 10' and the upper glass 12' respectively up and down by using PVB film 11'. The lower glass 10' and the upper glass 12' are pasted together with the PVB film 11' to complete the production. Although the...
