[0021] In order to make the purpose, technical scheme and advantages of the embodiment of the utility model clearer, the technical scheme in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model. It should be noted that the embodiments in this application and the features in the embodiments can be combined with each other arbitrarily without conflict.

[0022] See also Figures 1 to 3 A fireproof decorative panel according to an embodiment of the utility model comprises a glass magnesium board 1 and two glass fiber resin boards 2, wherein the bottom surface of the first glass fiber resin board 2 is connected to the top surface of the glass magnesium board 1, and the top surface of the second glass fiber resin board 2 is connected to the bottom surface of the glass magnesium board 1.

[0023] Here, the glass magnesium board 1 is a glass magnesium fireproof board, which has the characteristics of high temperature resistance and flame retardancy; the glass fiber resin board 2 has the characteristics of fire prevention, heat insulation and anti-conductivity. The two glass fiber resin boards 2 and the glass magnesium board 1 are connected to form a decorative panel to ensure that the decorative panel has high fire resistance.

[0024] The two glass fiber resin boards 2 can be symmetrically arranged about the axis of the glass magnesium board 1 , and the axis of the glass fiber resin board 2 is parallel to the axis of the glass magnesium board 1 .

[0025] Specifically, the glass magnesium board 1 is a rectangular board, and the glass fiber resin board 2 is a rectangular board.

[0026] The glass magnesium board 1 may include an intermediate layer 11 and two sanding layers 12 , wherein the bottom surface of the first sanding layer 12 is connected to the top surface of the intermediate layer 11 , and the top surface of the second sanding layer 12 is connected to the bottom surface of the intermediate layer 11 .

[0027] Specifically, the fireproof decorative panel in the present application may include an intermediate base layer and a pattern layer. The intermediate base layer is an inorganic board. The inorganic board may be a glass magnesium board 1 with a thickness of 6-10 mm, wherein the inorganic board may preferably be a double-sanded glass magnesium board. The glass magnesium board 1 is light in weight and has good strength. At the same time, the double-sided sanding structure is beneficial to the overall stability of the board after pressing and compounding, and is also beneficial to the surface bonding strength after compounding, so that it is more resistant to water boiling and has stronger stability (ordinary glass magnesium boards are single-sided sanded glass magnesium boards, one side of which has a sanded layer 12 and one side of which has a glass fiber layer. The glass fiber layer is relatively smooth, and the structural strength with the glass fiber resin board 2 is not easy to be insufficient). If the intermediate base layer uses cement fiber board, the structural strength with the glass fiber resin board 2 is not enough, and it is easy to delaminate when boiled. The intermediate layer 11 and the sanded layer 12 can both be rectangular layers.

[0028] Specifically, the middle layer 11 mainly plays a certain role in reducing weight. Some expanded vermiculite and wood powder are added. The sanding layer 12 will be denser to ensure flatness. The raw materials of the middle layer 11 and the sanding layer 12 are both magnesia cement; the glass magnesium board 1 is rolled multiple times, and the sanding layer 12 + middle layer 11 + sanding layer 12 are paved in three steps to form it at one time. The sanding layer 12 uses magnesia cement. For flatness, the slurry volume of the sanding layer 12 is relatively dense; the middle layer 11 uses magnesia cement + lightweight filler to reduce weight. The upper and lower sanding layers 12 are for the symmetry of the board structure, stress balance, and prevention of deformation. Compared with the asymmetric structure of the ordinary glass magnesium board 1, the glass magnesium board 1 in the present application is a symmetrical structure.

[0029] The glass fiber resin board 2 may include a triamine paper layer 21, a glass fiber resin sheet layer 22, and a pulp sheet layer 23. The top surface of the glass fiber resin sheet layer 22 is connected to the bottom surface of the triamine paper layer 21, the bottom surface of the glass fiber resin sheet layer 22 is connected to the top surface of the pulp sheet layer 23, the axis of the triamine paper layer 21 is parallel to the axis of the glass fiber resin sheet layer 22, and the axis of the glass fiber resin sheet layer 22 is parallel to the axis of the pulp sheet layer 23.

[0030] Specifically, the pattern layer uses a glass fiber resin board 2, which is formed by overlapping three layers of triamine paper + glass fiber resin skin + pulp sheet and pressing them through boiler-heated steel plates as needed. The triamine paper layer 21, the glass fiber resin sheet layer 22, and the pulp sheet layer 23 are all rectangular layers.

[0031] The top surface of the glass fiber resin sheet layer 22 can be bonded to the bottom surface of the triamine paper layer 21 , and the bottom surface of the glass fiber resin sheet layer 22 can be bonded to the top surface of the pulp sheet layer 23 .

[0032] Specifically, the three layers of triamine paper layer 21 + glass fiber resin sheet layer 22 + pulp sheet layer 23 in the glass fiber resin board 2 are formed by hot pressing. This is direct hot pressing without brushing glue. The triamine paper layer 21 can be a melamine paper layer. The melamine paper layer heats the resin and melts to bring glue. In the preparation of the glass fiber resin board 2, melamine impregnated paper, glass fiber resin sheet, and pulp sheet are selected and pressed by boiler-heated steel plate. According to needs, the melamine impregnated paper adopts antibacterial type with an antibacterial rate of ≥99%. In order to meet the Class A fire protection requirements of the facing glass fiber resin board 2, the glass fiber ratio of the glass fiber resin sheet needs to be adjusted to ensure that the overall glass fiber resin board 2 meets the Class A fire protection and the calorific value is ≤3MJ / kg.

[0033] The pulp layer of the glass fiber resin board 2 can be bonded to a sanding layer 12 of the glass magnesium board 1 .

[0034] Specifically, brushing glue on the back of the glass fiber resin board 2 is equivalent to brushing glue on the pulp sheet 23, and then the glass fiber resin board 2 and the glass magnesium board 1 are composited together by hot pressing. After hot pressing, the triamine paper layer 21 + glass fiber resin sheet 22 + pulp sheet 23 have actually become one and penetrated each other because each layer of material is relatively thin.

[0035] The length of the sanding layer 12 can be equal to that of the middle layer 11 , the length of the triamine paper layer 21 is equal to that of the glass fiber resin layer 22 , the length of the glass fiber resin layer 22 is equal to that of the pulp layer 23 , and the length of the pulp layer 23 is equal to that of the sanding layer 12 .

[0036] Specifically, the width of the sanding layer 12 can be equal to the width of the middle layer 11 , the width of the triamine paper layer 21 is equal to the width of the glass fiber resin layer 22 , the width of the glass fiber resin layer 22 is equal to the width of the pulp layer 23 , and the width of the pulp layer 23 is equal to the width of the sanding layer 12 .

[0037] The thickness of the glass magnesium board 1 can be 6-10 mm.

[0038] Specifically, the thickness of the glass magnesium board 1 may be 6 mm.

[0039] The thickness of the glass fiber resin board 2 can be 0.7-1.3 mm.

[0040] Specifically, the thickness of the glass fiber resin board 2 may be 1 mm.

[0041] Specifically, a 1mm thick glass fiber resin board 2 is placed on the upper and lower layers of a 6mm glass magnesium board 1, and water latex is brushed on the glass fiber resin board 2 and then pressed by a press to prepare a finished product of 8mm A-class fireproof decorative panel. The glass magnesium board 1 adopts a double-sided sanding structure and has a certain symmetry. Glue is applied on the pulp layer of the glass fiber resin board 2 so that the pulp layer of the glass fiber resin board 2 can be bonded to a sanding layer 12 of the glass magnesium board 1. The glue adopts environmentally friendly polyurethane water latex or acrylic water latex to ensure environmental performance.

[0042] The two sanding layers 12 may be symmetrically arranged about a central axis, and the axis of the sanding layer 12 is parallel to the axis of the middle layer 11 .

[0043] Specifically, the second glass fiber resin board 2 can be a non-facing glass fiber resin board 2 to reduce costs.

[0044] Specifically, compared with metal plates, the price of this application is cheaper; compared with inorganic pre-coated panels, the stability of this application is stronger, while also taking into account better finishing effects; compared with compact boards, this application is more environmentally friendly and has more outstanding fire resistance, meeting Class A fire protection requirements; compared with ice and fire boards, this application has a better finishing texture and the processing technology is more stable and controllable.
