[0002] Granite slab is a commonly used building decoration material. It is a slab made of natural granite through cutting, grinding, polishing and other processes. Granite has the characteristics of lasting color and uniform texture. The color and texture of granite slab are rich and varied. It can be selected according to different decoration styles and needs. Therefore, granite slab is widely used in indoor and outdoor walls, floors, countertops, columns and various sculptures and other decoration fields.

[0003] Although the existing granite slabs have certain fire resistance, their fire resistance still needs to be further improved in some special occasions, such as kitchens and laboratories. It is difficult to effectively prevent the spread of fire. In these special occasions, granite slabs may also cause more serious safety accidents due to their inability to effectively withstand high temperatures, reducing the practicality of granite slabs. Summary of the invention

[0004] Therefore, in order to solve the above-mentioned shortcomings, the utility model provides a fireproof granite slab to solve the above-mentioned technical problems.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a fireproof granite board, comprising a granite board substrate, the front end surface of the granite board substrate is coated with a glass ceramic coating, and the rear end surface of the granite board substrate is fixed with a gypsum board, and the outer surface of the glass ceramic coating is coated with a transparent epoxy resin coating;

[0006] The rear end surface of the gypsum board is coated with a heat insulation coating, and a groove is provided on the rear end surface of the gypsum board, and the interior of the groove is filled with an extension body integrally formed with the heat insulation coating.

[0016] In order to further explain the technical solution of the present utility model, it is described in detail through specific embodiments below.

[0017] like Figure 1 As shown, the utility model provides a fireproof granite slab, including a granite slab substrate 1.

[0018] like Figure 1 and Figure 2 As shown, in this embodiment, the front end surface of the granite plate substrate 1 is coated with a glass ceramic coating 2 flush with the side surface of the granite plate substrate 1, and the rear end surface of the granite plate substrate 1 is fixed with a gypsum board 4, and the outer surface of the glass ceramic coating 2 is coated with a transparent epoxy resin coating 3, which is used to improve the moisture resistance and crack resistance of the granite plate;

[0019] The rear end surface of the gypsum board 4 is coated with a heat-insulating coating 5, and a groove 6 is provided on the rear end surface of the gypsum board 4. The interior of the groove 6 is filled with an extension body 7 integrally formed with the heat-insulating coating 5, so as to increase the contact surface between the heat-insulating coating 5 and the gypsum board 4 and reduce the possibility of the heat-insulating coating 5 falling off.

[0020] The gypsum board 4 is flush with the side surface of the granite board substrate 1, which improves the aesthetics of the connection between the gypsum board 4 and the granite board substrate 1;

[0021] In this embodiment, the side surface of the granite slab base 1 is connected to the front end surface through the inclined surface 8, so that the adjacent inclined surfaces 8 of the two granite slabs form a strip groove when installed, and then the strip groove is filled with fireproof sealant to reduce the spread of fire in the gap between adjacent granite slabs;

[0022] In this embodiment, the cross section of the inner side of the groove 6 is a trapezoid, and the extension body 7 is a corresponding trapezoidal structure, so that the heat insulation coating 5 can be more stably attached to the gypsum board 4 by the extension body 7 cooperating with the groove 7;

[0023] In this embodiment, the heat-insulating coating 5 is a silicate heat-insulating coating, which has good heat-insulating properties and effectively prevents heat transfer;

[0024] When in use, the transparent epoxy resin coating 3 improves the moisture resistance and crack resistance of the granite slab, which can reduce safety hazards. In the event of a fire, the glass ceramic coating 2 can effectively prevent the spread of fire and reduce the expansion of the fire, making the granite slab have better fire resistance. The gypsum board 4 and the thermal insulation coating 5 improve the thermal insulation performance of the granite slab and reduce the heat transfer rate of the granite slab, so as to provide better fire protection for the building.

[0025] The above description is only a preferred example of the present invention and is not intended to limit the present invention. Although the present invention is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
