Description

Technical Field

[0001] This utility model relates to the field of flame-retardant honeycomb panel technology, specifically a high-strength flame-retardant composite honeycomb panel. Background Technology

[0002] Flame-retardant honeycomb panels are a type of board material with excellent flame-retardant properties. They are mainly used in construction projects and interior and exterior decoration, effectively preventing the spread of flames in the event of a fire and ensuring the safety of people and property. Flame-retardant honeycomb panels typically use aluminum as the face panel and aluminum honeycomb core as the core material. This structure results in virtually no flammable substances except for an extremely thin layer of coating and adhesive, thus determining its excellent flame-retardant performance. In addition, flame-retardant honeycomb panels also have moisture-proof, shock-proof, and anti-static properties, and are recyclable, making them an environmentally friendly material.

[0003] While current flame-retardant honeycomb panels can prevent fire from contacting the honeycomb core through their surface aluminum plate, the heat from the fire can still be transferred to the honeycomb core through the aluminum plate, making the honeycomb core still susceptible to combustion. Therefore, we propose a high-strength flame-retardant composite honeycomb panel. Utility Model Content

[0004] The purpose of this invention is to provide a high-strength flame-retardant composite honeycomb panel that can block the heat transfer between the surface aluminum plate and the honeycomb core panel, thereby preventing the honeycomb core panel from burning due to heat. This further improves the flame-retardant performance of the flame-retardant honeycomb panel and solves the problem that although current flame-retardant honeycomb panels can block the fire from contacting the honeycomb core panel through their surface aluminum plate to play a flame-retardant role, the heat of the fire can still be transferred to the honeycomb core panel through the aluminum plate, making it possible for the honeycomb core panel to burn.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-strength flame-retardant composite honeycomb panel, comprising an aluminum frame, an aluminum plate, and a honeycomb core panel. The honeycomb core panel is fixedly installed inside the aluminum frame, and an aluminum plate is fixedly installed on the inner wall of the aluminum frame above the honeycomb core panel. A heat-insulating coating is provided on the lower surface of the aluminum plate and the inner wall of the aluminum frame. Flame-retardant and sound-insulating panels are fixedly installed inside the aluminum frame above and below the honeycomb core panel.

[0006] Preferably, both the upper surface of the aluminum plate and the outer surface of the aluminum frame are provided with a wear-resistant coating. The wear-resistant coating can improve the wear resistance of the aluminum frame and the surface of the aluminum plate, and extend the service life of the aluminum frame and the aluminum plate. Flame-retardant and sound-insulating boards are fixedly installed inside the aluminum frame at positions above and below the honeycomb core board.

[0007] Preferably, the inner wall of the aluminum frame and the lower surface of the aluminum plate are provided with mesh reinforcing ribs. The mesh reinforcing ribs can further improve the structural strength of the aluminum plate and the aluminum frame, thereby improving the structural strength of the entire flame-retardant honeycomb panel.

[0008] Preferably, the honeycomb core panel is filled with foam, which fills the honeycomb pores of the honeycomb core panel, thereby improving the impact resistance of the flame-retardant honeycomb panel.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] 1. This utility model, by setting an aluminum frame, aluminum plate, honeycomb core panel and heat insulation coating, achieves the effect of blocking the heat transfer between the surface aluminum plate and the honeycomb core panel, thus preventing the honeycomb core panel from burning due to heat, and further improving the flame retardant performance of the flame retardant honeycomb panel. The aluminum plate, aluminum frame and honeycomb core panel constitute the flame retardant honeycomb panel. The aluminum plate and aluminum frame give the flame retardant honeycomb panel high strength, while also blocking the direct contact between the fire and the honeycomb core panel. Furthermore, since the heat insulation coating can block the heat transfer between the surface aluminum plate and the honeycomb core panel, it further avoids the temperature rise of the honeycomb core panel, thus preventing the honeycomb core panel from burning due to heat.

[0011] 2. By setting up mesh reinforcing ribs, this utility model can further improve the structural strength of the aluminum plate and aluminum frame, thereby improving the structural strength of the entire flame-retardant honeycomb panel.

[0012] 3. By setting a wear-resistant coating, this utility model can improve the wear resistance of the aluminum frame and aluminum plate surface, and extend the service life of the aluminum frame and aluminum plate.

[0013] 4. By setting flame-retardant and sound-insulating panels, this utility model can achieve the effect of sound insulation and improve the sound insulation performance of flame-retardant honeycomb panels. Attached Figure Description

[0018] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0019] like Figures 1-3As shown, this utility model proposes a high-strength flame-retardant composite honeycomb panel, comprising an aluminum frame 1, an aluminum plate 2, and a honeycomb core panel 7. The aluminum frame 1 is hollow inside and has an open upper surface. The honeycomb core panel 7 is fixedly installed inside the aluminum frame 1 and is glued to the inside of the aluminum frame 1. An aluminum plate 2 is fixedly installed on the inner wall of the aluminum frame 1 above the honeycomb core panel 7. The aluminum plate 2 and the aluminum frame 1 are fixed together by welding or glue. The aluminum plate 2 seals the opening on the upper surface of the aluminum frame 1, so that the honeycomb core panel 7 is located inside the sealed cavity formed by the aluminum plate 2 and the aluminum frame 1, thus blocking the direct contact between the fire and the honeycomb core panel 7. The aluminum plate 2, the aluminum frame 1, and the honeycomb core panel 7 constitute a flame-retardant honeycomb panel. The aluminum plate 2 and the aluminum frame 1 give the flame-retardant honeycomb panel high strength. Both the upper surface of the aluminum plate 2 and the outer surface of the aluminum frame 1 are provided with a wear-resistant coating 3, which can improve the strength of the aluminum frame 1 and the outer surface of the aluminum frame 1. The wear resistance of the aluminum plate 2 surface extends the service life of the aluminum frame 1 and the aluminum plate 2. The lower surface of the aluminum plate 2 and the inner wall of the aluminum frame 1 are provided with a heat insulation coating 5. The heat insulation coating 5 can block the heat transfer between the surface aluminum plate 2 and the honeycomb core panel 7, thereby preventing the temperature of the honeycomb core panel 7 from rising and burning due to heat, thus improving the flame retardant performance of the flame retardant honeycomb panel. Flame retardant sound insulation boards 6 are fixedly installed above and below the honeycomb core panel 7 inside the aluminum frame 1. The flame retardant sound insulation boards 6 can play a sound insulation role and improve the sound insulation performance of the flame retardant honeycomb panel. The inner wall of the aluminum frame 1 and the lower surface of the aluminum plate 2 are provided with mesh reinforcing ribs 4. The mesh reinforcing ribs 4 can further improve the structural strength of the aluminum plate 2 and the aluminum frame 1, thereby improving the structural strength of the entire flame retardant honeycomb panel. The honeycomb core panel 7 is filled with foam 8. The foam 8 is filled in the honeycomb holes of the honeycomb core panel 7, which improves the impact resistance of the flame retardant honeycomb panel.

[0020] In use, the aluminum plate 2, aluminum frame 1, and honeycomb core panel 7 form a flame-retardant honeycomb panel. The aluminum plate 2 and aluminum frame 1 give the flame-retardant honeycomb panel high strength and also prevent the fire from directly contacting the honeycomb core panel 7. Furthermore, since the heat insulation coating 5 can block the heat transfer between the surface aluminum plate 2 and the honeycomb core panel 7, the temperature of the honeycomb core panel 7 is prevented from rising, thus preventing the honeycomb core panel 7 from being heated and burning, thereby improving the flame-retardant performance of the flame-retardant honeycomb panel.

[0021] The above specific embodiments are merely several preferred embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
