Description

Technical Field

[0001] The invention relates to the technical field of fireproof door preparation technology, in particular to a process technology for using a low-density grey silicon board for a fireproof door. Background Art

[0002] A fire door is a facility used for fire separation in buildings. In addition to the functions of ordinary doors, fire doors can prevent the spread of fire and smoke. When a fire occurs, they can isolate the fire source, prevent the spread of fire, and buy time for fire rescue. Traditional fire doors can be divided into two types according to their materials: wooden fire doors and steel fire doors. The installation process of traditional fire doors is as follows: door opening treatment → grouting in door frame → door frame placement and temporary fixation → door frame fixation → treatment of the gap between door frame and wall → door leaf installation → hardware accessories installation → cleaning.

[0003] Among them, steel fire doors are more expensive, have a simple appearance, and the density of steel is higher, which makes steel fire doors relatively heavy. It is inevitable to pay attention to the load-bearing problem during installation and use. Wooden fire doors have poor fire resistance and can generally only achieve a fire resistance level of 30 or 60 minutes. They also have a short service life, poor strength and durability, and are easily infested and decayed in humid environments. There is a lack of a fire door with good fire resistance and low cost that combines the advantages of both steel and wooden fire doors. Summary of the invention

[0004] The purpose of the present invention is to provide a process technology for using low-density grey silicon boards for fire doors to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a process technology for using low-density grey silica board for fireproof doors, comprising a door panel, wherein a first fireproof board is installed inside both upper and lower sides of the door panel, a hardwood board is installed on the side of the first fireproof board away from the middle of the door panel, a glue layer is bonded between the hardwood board and the first fireproof board, a first edge sealing board is installed inside one side of the door panel, a second fireproof board is installed inside the first edge sealing board, a second edge sealing board is installed inside the other side of the door panel, a fourth fireproof board is installed inside the second edge sealing board, a third fireproof board is installed inside the fourth fireproof board, a reinforcement board is installed inside the third fireproof board, mounting screws are provided through the middle of the reinforcement board, and air holes are provided through the middle of the first fireproof board and the hardwood board on the upper and lower sides of the door panel.

[0006] Preferably, the first fireproof board, the second fireproof board, the third fireproof board and the fourth fireproof board are all multi-layer board structures, and the first fireproof board, the second fireproof board, the third fireproof board and the fourth fireproof board are made of any one of fiber cement board, calcium silicate board and low-density gray silica board.

[0007] Preferably, the hardwood board is connected to the first fireproof board via a glue layer.

[0008] Preferably, the first edge sealing board and the second edge sealing board are respectively nailed and fixed to the second fireproof board and the fourth fireproof board by U-shaped nails.

[0009] Preferably, the mounting screws penetrate the reinforcing plate and are connected to the third fireproof plate.

[0010] A process technology for using low-density gray silicon board for fire doors includes the following steps: S1: Before assembly, the door panels are cut up, down, left, and right to form a size of 898.4x2013mm; S2: Press a layer of braided yarn bundle and glass fiber cloth on the surface of the door panel in sequence, with the sizes of 770x1896mm and 800x1896mm respectively, and place the braided yarn bundle and glass fiber cloth in the middle of the left and right when pressing, with the height aligned with the inner rib; S3: Use U-shaped nails to nail the first edge sealing board and the second edge sealing board to the second fireproof board and the fourth fireproof board respectively; S4: A6000 glue is squeezed between the hardwood board and the first fireproof board on the upper and lower sides of the door panel to form a glue layer, so that the hardwood board and the first fireproof board are bonded; S5: Pre-drill holes on the reinforcement plate, and screw through the reinforcement plate to connect it to the third fireproof plate; S6: Squeeze fireproof silicone INSS2460 into the gaps between the upper and lower sides and the left and right sides of the door panel to fill them; S7: Stamp one side of the door panel to distinguish the lock edge, and mark the order number on the other side; S8: Phenolic aldehyde is poured into the door panel through the vent holes reserved on the upper and lower sides of the door panel. The specific gravity of phenolic aldehyde is 0.13g / cm. After pouring, the filling quality is checked by terahertz. S9: Trim the upper and lower sides of the door panel to make the height of the door panel 2007mm.

[0011] Preferably, after the braided yarn bundle and the glass fiber cloth are pressed in S2, a primer is sprayed on the inner side of the door panel to increase the phenolic adhesiveness.

[0012] Preferably, the thickness of the hardwood board in S4 is 15 mm.

[0013] Compared with the prior art, the present invention has the following beneficial effects: The process technology of using low-density gray silica board for fire doors increases the fire resistance of fire doors by using low-density gray silica board, calcium silicate board and fiber cement board. The fire resistance time can reach 1-4 hours, which can effectively prevent the spread of fire and improve the safety of buildings.

The fireproof boards made of low-density grey silica board, calcium silicate board and fiber cement board have good flexibility and elasticity. When used to make fire doors, they can replace traditional rigid boards. They are easy to construct and shape. 9mm can achieve 650mm diameter cylindrical bending, which can provide fire doors with beautiful appearance while ensuring fire resistance, making up for the defects of traditional steel fire doors with single appearance and high cost.

[0016] This low-density gray silica board is used in the process technology of fire-proof doors. The fire-proof boards made of low-density gray silica board, calcium silicate board and fiber cement board have good processing performance. Compared with steel, they are lighter in weight and can be used like wood. They can be nailed, sawed, planed, grooved and carved, which reduces the labor intensity of construction, improves construction efficiency and wide application.

[0032] like Figures 1 to 8 As shown, the low-density gray silicon board fireproof door of this embodiment includes a door panel 1, and first fireproof panels 2 are installed inside the upper and lower sides of the door panel 1 for fireproofing and heat insulation on the upper and lower sides of the door panel 1. A hardwood board 3 is installed on one side of the first fireproof panel 2 away from the middle of the door panel 1 for edge sealing on the upper and lower sides of the door panel 1. A glue layer 4 is bonded between the hardwood board 3 and the first fireproof panel 2. The glue layer 4 is solidified using A6000 glue. A first edge sealing board 6 is installed inside one side of the door panel 1 for edge sealing on the hinge side of the door panel 1. A first edge sealing board 6 is installed inside the first edge sealing board 6. A second fireproof board 5 and a second edge sealing board 11 are installed inside the other side of the door panel 1 for locking and sealing the edge of the door panel 1; a fourth fireproof board 10 is installed inside the second edge sealing board 11; a third fireproof board 7 is installed inside the fourth fireproof board 10; a reinforcing board 8 is installed inside the third fireproof board 7; a mounting screw 9 is penetrated in the middle of the reinforcing board 8 for connecting the inner third fireproof board 7; air holes 12 are penetrated in the middle of the first fireproof board 2 and the hardwood board 3 on the upper and lower sides of the door panel 1; the air holes 12 are reserved for injecting phenolic formaldehyde into the door panel 1.

[0033] Specifically, the first fireproof board 2, the second fireproof board 5, the third fireproof board 7 and the fourth fireproof board 10 are all multi-layer board structures, the specific gravity of the multiple fireproof boards is 1.0, and the width is 12.5mm.
