Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention provides a composite board suitable for use in places where impact resistance, ballistic resistance, soundproofing and transparency are required.

[0002]

2. Description of the Related Art Tempered glass, laminated glass, and composite plates are used for buildings in which financial institutions and institutions requiring special confidentiality are located, windows for displaying expensive products, and the like.

Generally, tempered glass is formed by heating a glass plate to a softening point (about 700 ° C.), then uniformly blowing air at room temperature and then rapidly cooling it. The laminated glass is a combination of a plurality of glasses. It is formed by combining glass with various properties depending on the application. Further, the composite plate is formed by integrally combining a glass plate, an FRP, a melanin resin plate, stone, a metal plate and the like.

FIG. 4 shows an example of a laminated glass using a conventional tempered glass. In the laminated glass shown in FIG. 4, a tempered glass 2 is arranged between two glasses 1 and 1,
The tempered glass 2 and the glass 1 on both sides thereof are bonded and integrated by a polyvinyl butyral film 3.

Next, FIG. 5 shows an example of a conventional composite plate using a porous metal plate or a mesh metal plate. In the composite plate shown in FIG. 5, a porous metal plate or a mesh metal plate 5 is arranged between two glass plates 4 and 4, and the porous metal plate or the mesh metal plate 5 and the glass plates 4 on both sides are transparent. They are bonded and integrated with each other through an adhesive layer 6 made of a polymer material.

[0006]

By the way, the conventional laminated glass shown in FIG. 4 has a problem that it cannot be used as glass requiring mechanical strength such as particularly high impact resistance and ballistic resistance, and its weight is large. There is a problem that it is bulky and requires a lot of labor for packing and mounting work.

The conventional composite plate shown in FIG. 5 has high mechanical strength and excellent sound insulation. However, there is a problem that the transparency is poor, and there is a problem that the weight is increased.

The main object of the present invention is that the mechanical strength is high,
It is also to provide a lightweight composite board that is excellent in transparency and soundproofing.

Another object of the present invention is to provide a composite plate in which fragments are not shattered and scattered even when the glass plate is broken.

[0010]

To achieve the above object, in the present invention, Delaglass K (trade name, manufactured by Asahi Chemical Industry Co., Ltd.) is arranged between a plurality of glass plates to make the glass plate and the Delaglass K transparent. Adhesive and integrated with a simple resin adhesive layer.

In order to achieve the above object, the transparent resin-based adhesive layer is formed by ALMATEX DC100 (trade name, manufactured by Mitsui Toatsu Chemicals, Inc.).

[0012]

In the present invention, the dera-glass K is arranged between a plurality of glass plates and is bonded and integrated with the glass plates. This Delaglas K has a tensile strength of 1.49 kg / cm @ 2,
Breaking elongation = 5%, bending strength = 1.250 kg / cm2,
Bending elastic modulus = 35.000 kg / cm @ 2, Izod impact strength (notched) = 2.0 kg.cm/cm, Rockwell hardness = M105, and the mechanical strength is large. In the present invention, since the characteristic of the Delagrass K having high mechanical strength is utilized to the maximum extent, it can be generally used as a glass building material for a structure which requires impact resistance and ballistic resistance.

Further, in the present invention, the glass plate and the delagrass K are adhered and integrated with each other through the transparent resin adhesive layer. The Delaglas K has a light transmittance of 93% and is excellent in light transmittance. Therefore, in the present invention, the mechanical strength can be increased and the permeability can be increased.

Further, the Delaglass K has a specific gravity of 1.
It is 19 and can be significantly reduced in weight as compared with a conventionally used laminated glass using tempered glass and a composite plate using a porous metal plate, a mesh metal plate, or the like. As a result, it is possible to save labor in packing and installation work.

Further, as a result of experiments, Delagrass K has excellent soundproofing properties. Therefore, the present invention can also improve soundproofing.

Further, in the present invention, the transparent resin-based adhesive layer is formed by ALMATEX DC100. This ALMATEX DC100 has high adhesiveness. Therefore, by using ALMATEX DC100, the glass plate and the Delaglass K can be bonded together,
When the glass plate is broken, it is possible to solve the problem that the fragments are shattered and scattered.
