Description

Technical Field

[0001] The invention relates to the technical field of fireproof panels, in particular to a fireproof panel for building fire protection and a preparation method thereof. Background Art

[0002] Fireproof panels are also called fire-resistant panels. Fireproof panels are composed of surface paper + colored paper + multiple layers of kraft paper; fireproof panels are widely used in interior decoration, furniture, kitchen cabinets, laboratory countertops, exterior walls and other fields. Fireproof panels are wear-resistant, durable consumer products with high temperature, scratch-resistant, anti-penetration and easy to clean; the product refers to a non-combustible and fire-resistant panel wrapped around the steel structure (beams and columns) in a specific connection, fixation and combination method, thereby delaying the rapid heating of steel and reducing its strength when a fire occurs, and avoiding the steel structure from losing its supporting capacity and causing the collapse of the building or structure; the base material of the fireproof door panel is particleboard, moisture-proof board or density board, and the surface is decorated with fireproof panels; fireproof panels are made of siliceous materials or calcareous materials as the main raw materials, mixed with a certain proportion of fiber materials, lightweight aggregates, adhesives and chemical additives, and made of decorative panels through autoclaving technology. Fireproof panels are a new type of material that is used more and more, and the use of fireproof panels is not only for fire prevention.

[0003] The types of fireproof boards can be divided into: according to the thickness of use, they can be divided into thin fireproof boards and thick fireproof boards; according to the density of the fireproof boards, they can be divided into low-density fireproof boards, medium-density fireproof boards and high-density fireproof boards.

[0004] However, the preparation of existing fireproof panels has the following shortcomings:

[0005] Most of the existing fireproof panels are made of single-layer structure. Due to the limited range of raw materials used in the single-sided structure, the structural strength and resistance of the fireproof panels are poor. In addition, in the process of preparing the fireproof panels, after the panels are finalized, they need to be cut to make the specifications of the panels the same. Since waste will appear in the cutting process, the production cost and loss of the panels are high. At the same time, the surface structure of some fireproof panels is made of non-metallic materials, so that the surface of the fireproof panels will be corroded or worn when in use, resulting in reduced fireproof performance of the fireproof panels.

[0006] Therefore, we propose a fireproof board for building fire protection and a preparation method thereof, so as to solve the above-mentioned problems. Summary of the invention

[0007] The object of the present invention is to provide a fireproof board for building fire protection and a preparation method thereof. By setting the outer surface of the board to a metal material, the internal structure and materials can be protected and the damage to the board structure can be reduced. At the same time, the board is set to a composite type, which can ensure the fireproof performance of the board while improving the structural strength and resistance of the board. At the same time, by pre-treating the board model, the board model can be adjusted to a suitable specification, thereby reducing the cutting of the board after the board is formed, reducing the loss in the board preparation process, and by stacking the composite boards for production, the use of adhesives can be reduced. The use of rivets to install the external metal layer on the protective layer can also reduce the use of adhesives, improve the environmental protection of the board production process, and improve the bonding effect between the boards to solve the problems raised by the above-mentioned background technology.

[0008] To achieve the above-mentioned object, the present invention provides the following technical solutions: a fireproof board for building fire protection and a preparation method thereof, comprising: a fireproof board, the fireproof board is made of a composite of multiple layers of materials, the fireproof board comprises a surface metal layer and a first composite interlayer, the first composite interlayer is arranged on the lower surface of the surface metal layer, a second composite interlayer is arranged on the lower surface of the first composite interlayer, a third composite interlayer is arranged on the lower surface of the second composite interlayer, and an inner surface protective layer is arranged on the lower surface of the third composite interlayer;

[0009] The surface metal layer is made of an aluminum plate, the thickness of which is 1.5 mm. The surface metal layer can increase the protection and wear resistance of the outer side of the fireproof plate.

[0010] The first composite interlayer is made of gypsum material and glass fiber cloth, the thickness of the first composite interlayer is 5 mm, and the first composite layer is used to increase the strength of the internal structure of the board;

[0011] The second composite interlayer is made of magnesium oxide as a base material, the thickness of the second composite interlayer is 10 mm, and the second composite interlayer is a main flame retardant layer;

[0012] The third composite interlayer is made of quartz powder as a base material, the thickness of the third composite interlayer is 3 mm, and the third composite interlayer is used to assist the second composite interlayer in flame retardancy;

[0013] The inner surface protective layer is made of aluminum plate, and the thickness of the inner surface protective layer is 0.35mm. The inner surface protective layer is used to increase the protectiveness of the surface of the fireproof board. By setting the outer surface of the fireproof board to metal material, the internal structure and materials can be protected and the damage to the board structure can be reduced. At the same time, the board is set to a composite type, which can ensure the fireproof performance of the board while improving the structural strength and resistance of the board. At the same time, through the pretreatment of the board model, the board model can be adjusted to a suitable specification, thereby reducing the cutting of the board after the board is formed, and reducing the loss in the board preparation process. By stacking the composite boards for production, the use of adhesives can be reduced. The use of rivets to install the external metal layer on the protective layer can also reduce the use of adhesives, improve the environmental protection of the board production process, and improve the bonding effect between the boards.

The second composite interlayer is pressed and formed to fit on the first composite interlayer. The mold is then moved to the pre-drying area and dried with the help of equipment. When the water content of the second composite interlayer is reduced to 50%, the mold with the built-in composite plate is placed back in the mold area;

[0017] Further, the quartz powder used for the third composite interlayer is put into water at a ratio of 2:1, and the mixed quartz powder is put into a stirring device, and the stirring device stirs the quartz powder.

After completing the above operations, the mold is moved to the extrusion area, and the extrusion equipment works to press the third composite interlayer in the mold. The third composite interlayer is pressed into shape and adhered to the surface of the second composite interlayer. Then the mold is moved into the pre-drying area, and the third composite interlayer is dried with the help of the equipment. When the water content of the third composite interlayer is reduced to 75%, the composite plate is taken out;

[0018] Further, the composite interlayer is placed in a drying device, and the composite interlayer is dried for a total of two hours at 50°C / 15min, 100°C / 30min, 120°C / 35min, and 150°C / 40min. After the drying is completed, the composite interlayer is taken out and its surface is flattened;

[0019] Furthermore, after the flattening process is completed, circular holes are punched on the four corners of the composite plate. After the operation is completed, the surface metal layer and the inner surface protective layer are respectively installed on the surface of the first composite interlayer and the surface of the third composite interlayer with the help of rivets.

After completing the above operations, the mold is moved to the extrusion area, and the extrusion equipment works to press the third composite interlayer in the mold. The third composite interlayer is pressed into shape and adhered to the surface of the second composite interlayer. Then the mold is moved into the pre-drying area, and the third composite interlayer is dried with the help of the equipment. When the water content of the third composite interlayer is reduced to 75%, the composite plate is taken out;

[0041] Further, the composite interlayer is placed in a drying device, and the composite interlayer is dried for a total of two hours at 50°C / 15min, 100°C / 30min, 120°C / 35min, and 150°C / 40min.
