Abstract

The utility model relates to a combined type glass blank, its characterized in that: comprises a first glass plate and a second glass plate mutually bonded with the first glass, wherein the second glass plate is a toughened glass plate. The utility model discloses combined type glass blank adds a second glass board through first glass board back, and first glass board is ordinary glass, and both become composite glass to reducible glass breaks, and in case break or burst, first glass board still pastes with the second glass board and is in the same place, makes the piece can not splash or drop, has guaranteed safety.

Description

Composite glass white board

The technical field is as follows:

the utility model relates to a combined type glass blank.

Background art:

the current glass whiteboards are all in a transparent or back printing form, but generally have the following disadvantages: 1. the thickness of the common glass white board is 4mm, when writing on the surface of the white board, light rays penetrate through the thickness of 4mm and are refracted, and the shadow of writing can be formed on the bottom surface, so that characters can be seen as double images, and visual discomfort of a viewer is caused. 2. When light irradiates, the common glass generates reflection, which stimulates eyes of a viewer, influences eyesight and causes eye fatigue. 3. The glass itself is brittle and, in the event of breakage or bursting, the shards can injure the user or bystanders.

The invention content is as follows:

to the above problem, the utility model provides a combined type glass blank, this combined type glass blank can prevent that glass from breaking and reducing the injury of the piece to the person that bursts.

The utility model discloses combined type glass blank, its characterized in that: comprises a first glass plate and a second glass plate mutually bonded with the first glass, wherein the second glass plate is a toughened glass plate.

Further, the first glass plate has a thickness of 1.1 mm.

Further, the second glass plate has a thickness of 1.1 mm.

Further, the front surface of the first glass plate is a matte diffuse reflection surface.

Furthermore, a projection film is attached between the first glass plate and the second glass plate.

Further, the back surface of the first glass plate is printed with a color layer.

Furthermore, the composite glass white board is embedded in furniture or a wall.

The utility model discloses combined type glass blank adds a second glass board through first glass board back, and first glass board is ordinary glass, and both become composite glass to reducible glass breaks, and in case break or burst, first glass board still pastes with the second glass board and is in the same place, makes the piece can not splash or drop, has guaranteed safety.

Description of the drawings:

FIG. 1 is a cross-sectional view of an embodiment of the present invention;

FIG. 2 is a cross-sectional view of a second embodiment of the present invention;

FIG. 3 is a cross-sectional view of a second embodiment of the present invention;

fig. 4 is a front view of the present invention.

The specific implementation mode is as follows:

the utility model discloses a composite glass white board, which comprises a first glass board 1 and a second glass board 2 mutually bonded with the first glass board 1, wherein the second glass board 2 is a toughened glass board; the first glass 1 and the second glass plate 2 may be adhered by glue or may be adhered by an adhesive film.

Furthermore, in order to prevent the writing written on the front surface of the first glass plate from generating shadow or ghost image, the thickness of the first glass plate is 1.1mm, because the thickness of the first glass plate is reduced to 1.1mm, the ultra-thin thickness is not easy to generate the shadow or ghost image of the writing, when the thickness of the first glass plate is more than 1.1mm, the shadow or ghost image can be generated, and the glass plate thinner than 1.1mm is easy to damage, difficult to manufacture and high in cost, so that the cost cannot be increased or the shadow or ghost image cannot be generated by adopting the glass plate of 1.1 mm.

The thickness of the same second glass plate was 1.1 mm.

Further, in order to prevent glare, the front surface 4 of the first glass plate is a matte diffuse reflection surface, and the front surface of the first glass plate is changed into the matte diffuse reflection surface through Anti-glare (AG, Anti-glare) processing, so that reflection influence can be reduced, the reflectivity is reduced in addition to glare prevention, light shadow is reduced, Anti-glare processing is commonly used for processing the surface of liquid crystal glass, and the method belongs to the prior art, so that a liquid crystal display cannot generate glare, and the same existing Anti-glare processing method is also adopted in the present application.

Furthermore, in order to make the glass can be used as a projection screen, a projection film 3 is stuck between the first glass plate and the second glass plate, and the projection film can be a curtain, so that the composite glass can be used as a white board and can also be used as a projection screen.

Furthermore, the back surface of the first glass plate is printed with a color layer 5, the color layer 5 can be a paint layer, and the back surface of the first glass plate can be printed with various required colors according to different requirements of different customers, so that the glass white plate can be made into 'white plates' with different colors according to the background of the office or education environment and the requirements of the customers.

Furthermore, in order to meet the requirements of different occasions, the composite glass white board is embedded in furniture or a wall 6.

Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting the same; although the present invention has been described in detail with reference to preferred embodiments, it should be understood by those skilled in the art that: the invention can be modified or equivalent substituted for some technical features; without departing from the spirit of the present invention, it should be understood that the scope of the claims is intended to cover all such modifications and variations.
