Description

Technical Field

[0001] The invention relates to an environmentally friendly flame-retardant decorative plate. Background Art

[0002] When doing interior decoration, the room needs to be divided. There are many ways to divide the room. The current mainstream methods are lightweight bricks, light steel keels, wooden partitions, etc. After the above-mentioned partitions are built, decorative panels need to be installed on the surface of the wall for surface decoration, which further increases the decoration cost.

[0003] The decorative boards in the prior art are mainly imitation wood grain boards or solid wood boards. Both the imitation wood grain boards and the solid wood boards will burn and have very poor flame retardancy. Therefore, during indoor decoration, this easy-to-burn-through characteristic can easily lead to the spread of fire.

[0004] Based on the above problems, we have designed an environmentally friendly flame-retardant decorative panel that can prevent fire from spreading. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide an environmentally friendly flame-retardant decorative plate which can achieve fireproofing and flame-retardant effects and prevent the spread of fire.

[0006] To solve the above problems, the present invention adopts the following technical solutions:

[0007] An environmentally friendly flame-retardant decorative board material comprises a sandwich panel and decorative panels arranged on the front and rear end surfaces of the sandwich panel, an inner frame is arranged inside the sandwich panel, the thickness of the inner frame is less than the thickness of the sandwich panel, and flame-retardant cotton is filled on both sides of the inner frame inside the sandwich panel.

[0008] Preferably, grooves are provided on the upper and lower surfaces of the sandwich panel, and sealing strips are embedded in the grooves. Mounting holes are drilled on the upper and lower end surfaces of the sandwich panel, and the mounting holes penetrate the sealing strip. Part of the sealing strip protrudes out of the groove, and the thickness of the protruding part is 1mm to 2mm. When installing adjacent sandwich panels, glue is applied on the contacting surfaces to reinforce the seal.

[0009] Preferably, the sandwich panel is an aluminum profile.

[0010] Preferably, the inner frame is lattice-shaped, and a fireproof component is arranged in each lattice.

[0011] Preferably, the fire protection assembly comprises a fire protection board.

[0012] Preferably, concave holes are provided at both ends of the fireproof board, springs are embedded in the concave holes, and first fireproof boards are provided on both sides of the fireproof board, the first fireproof board has through holes corresponding to the concave holes, and a meltable pressure plate is provided at the mouth of the through hole, one end of the spring is fixed to the concave hole, and the other end is compressed and embedded in the through hole, and is pressed by the pressure plate, the flame retardant cotton covers the first fireproof board, and after the decorative panel catches fire, the flame burns through the decorative panel, the flame retardant cotton is heated at this time, and the pressure plate is melted, and after the pressure plate is melted, the spring pops out to push the flame retardant cotton and the decorative panel apart, so that the flame retardant cotton and the decorative panel maintain a distance from the first fireproof board.

[0013] Preferably, the inner frame is an asbestos frame.

[0014] The production method is as follows:

[0015] First, fix the inner frame in the sandwich panel, and then embed the fireproof component into the inner frame. The fireproof board in the fireproof component is fixed to the inner frame by nail gun fixation.

[0016] Then lay flame-retardant cotton on the surface of the first fireproof board, and finally cover it with a decorative panel. When fixing the decorative panel, it is necessary to avoid the position of the spring.

[0017] The beneficial effects of the present invention are:

[0018] This product adopts a detachable structural design, and the decorative panels are installed independently for easy replacement. In the event of a fire, the decorative panels are bounced open by the fireproof components to prevent the product from being burned through by continuous flames, thereby extending the fireproof time. In addition, modular fireproof components are used to facilitate on-site repair after the fire is extinguished, without the need to remove the entire panel. After the repair, its fireproof performance is not affected, making it suitable for promotion and use. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] In the above technical scheme, the sandwich panel 1 is shaped and mainly supported, the upper and lower end surfaces of the sandwich panel 1 are fixed to the building by bolts, the inner frame 3 is fixed to the inside of the sandwich panel 1, and when fixing, it is necessary to ensure that the two sides of the inner frame 3 are retracted into the sandwich panel 1 to facilitate the laying of the flame retardant cotton 5. The function of the flame retardant cotton 5 is flame retardant. The decorative panel 2 is made of decorative materials, which can be stone, wood, or PVC material. The function of the decorative panel 2 is decoration. When the decorative panel 2 burns, the flame retardant cotton 5 is used to prevent the panel from being burned through, thereby preventing the spread of the fire.

[0032] See also Figure 4 As shown, grooves are provided at the upper and lower surfaces of the sandwich panel 1, and a sealing strip 101 is embedded in the groove. Mounting holes 102 are drilled at the upper and lower end surfaces of the sandwich panel 1, and the mounting holes 102 penetrate the sealing strip 101. Part of the sealing strip 101 protrudes out of the groove, and the thickness of the protruding part is 1mm to 2mm. When installing adjacent sandwich panels 1, glue is applied on the contacting surfaces to reinforce the seal.

[0033] In the above technical solution, the sandwich panel 1 is installed through the mounting holes 102 and bolts, and the sealing strip 101 is used to increase the sealing performance, reduce the assembly gap, and improve the insulation effect of the assembled panel.

[0034] See also Figure 2 As shown, the sandwich panel 1 is an aluminum profile.

[0035] Aluminum profiles are high in strength, light in weight and easy to install.

[0036] For market matching, low-priced steel can also be used as the material of the sandwich panel 1.

[0037] See also Figure 3 As shown, the inner frame 3 is in a lattice shape, and a fireproof component 4 is arranged in each lattice.

[0038] In the above technical solution, the lattice-shaped inner frame 3 is matched with the embedded fireproof component 4, which can play a fireproof effect when encountering a fire. The fireproof component 4 is not absolutely fireproof. After being damaged by burning, this modular structure is convenient for single replacement and later repair, rather than replacing the entire piece.

[0039] See also Figure 3 and Figure 5 As shown, the fire protection assembly 4 includes a fire protection board 41.

[0040] See also Figure 5As shown, recessed holes 42 are provided at both ends of the fireproof board 41, springs 43 are embedded in the recessed holes 42, first fireproof boards 44 are provided on both sides of the fireproof board 41, the first fireproof board 44 has through holes 45 corresponding to the recessed holes 42, and a meltable pressing plate 46 is provided at the orifice of the through hole 45, one end of the spring 43 is fixed to the recessed hole 42, and the other end is embedded in the through hole 45 after being compressed, and is pressed by the pressing plate 46, the flame retardant cotton 4 covers the first fireproof board 44, after the decorative panel 2 catches fire, the flame burns through the decorative panel 2, the flame retardant cotton 4 is heated at this time, the pressing plate 46 is melted, and after the pressing plate 46 is melted, the spring 43 pops out to push the flame retardant cotton 4 and the decorative panel 2 apart, so that the flame retardant cotton 4 and the decorative panel 2 maintain a distance from the first fireproof board 44.

[0041] In the above technical solution, the fireproof thickness is increased by the combination of the first fireproof board and the fireproof board 41, and the embedded spring 43 design does not affect the decorative effect of the decorative panel 2. When the decorative panel 2 burns, the heat is transferred to the pressure plate 46. After the pressure plate 46 melts, the spring 43 pops out, so that the flame retardant cotton 4 is bounced away a certain distance and separated from the first fireproof board 44, and the decorative panel 2 is also pushed away, avoiding the spread of fire, thereby improving the fire protection time of the board and providing valuable time for subsequent fire rescue.

[0042] Preferably, the inner frame 3 is an asbestos frame.

[0043] The production method is as follows:

[0044] First, the inner frame 3 is fixed in the sandwich panel 1, and then the fireproof component 4 is embedded in the inner frame 3. The fireproof board 41 in the fireproof component 4 is fixed to the inner frame 3 by nail gun fixing.

[0045] Then, flame retardant cotton 5 is laid on the surface of the first fireproof board 44 , and finally covered with the decorative panel 2 . When the decorative panel 2 is fixed, it is necessary to avoid the position of the spring 43 .
