Description

Technical Field

[0001] This utility model relates to the field of insulation board technology, specifically a compartmentalized fireproof insulation board. Background Technology

[0002] In the field of building engineering, insulation boards play a crucial role in achieving building energy conservation. Their core function is to effectively reduce the exchange of heat between the inside and outside of a building, thereby reducing the energy consumption of air conditioning and heating equipment. However, traditional insulation boards generally have a series of significant defects. In terms of fire resistance, most insulation materials are flammable or combustible. Once exposed to an open flame, they are prone to combustion, and the fire can spread rapidly inside the insulation board.

[0003] From a structural design perspective, the existing insulation boards have a relatively simple structure, mostly consisting of a single main panel with internal compartments. This structure is significantly lacking in overall stability and the synergistic effect of insulation and fire resistance, and has weak resistance to deformation.

[0004] To address these issues, this invention provides a compartmentalized fireproof insulation board. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a compartmentalized fireproof insulation board, which solves the aforementioned problems.

[0006] To achieve the above objectives, this utility model employs the following technical solution: a compartmentalized fireproof insulation board comprising two main panels. The main panels are made of flame-retardant polystyrene, a material with excellent flame-retardant properties that can, to a certain extent, prevent the spread of flames while also possessing structural strength, providing a stable outer support structure for the entire insulation board. The two main panels are respectively positioned on the front and rear sides of the board, jointly constructing the basic framework of the insulation board. Between the two main panels, crisscrossing insulation boards are provided, made of rock wool or calcium silicate. Both rock wool and calcium silicate are high-quality fireproof and heat-insulating materials, possessing advantages such as non-combustibility and good heat insulation performance. The insulation boards are arranged in a staggered manner, forming multiple independent compartments. Each compartment is filled with polystyrene foam or polyurethane foam at a density of 20-30 kg / m³. These filling materials have low thermal conductivity, effectively preventing heat transfer and providing excellent insulation. Meanwhile, the inner walls of the compartments are coated with intumescent fire-retardant paint, which is made of water-based environmentally friendly material and has an expansion ratio of ≥250%. When exposed to high temperatures or fire, the intumescent fire-retardant paint can expand rapidly to form a thick layer of heat-insulating charcoal, further enhancing the fire resistance of the compartments and effectively preventing the spread of fire between compartments.

[0007] Furthermore, the inner wall of the main body panel is provided with multiple heat insulation holes. These holes are circular, with a diameter of 8-12mm, and are arranged in a matrix within the main body panel, with a spacing of 20-30mm. The circular heat insulation holes maximize the heat conduction path within the same cross-sectional area, effectively reducing the thermal conductivity of the main body panel. Inside each heat insulation hole are multiple heat-conducting fins, made of aluminum alloy, numbering 6-8, with a thickness of 0.3-0.8mm, and evenly distributed circumferentially along the inner wall of the heat insulation holes. Aluminum alloy has excellent thermal conductivity, and the heat-conducting fins can quickly conduct and disperse heat generated locally on the main body panel, preventing excessively high local temperatures and ensuring temperature uniformity. This also enhances the structural strength of the main body panel to some extent, compensating for any weakening of the structure caused by the heat insulation holes.

[0008] Furthermore, the insulation board is bonded and fixed to the main board using high-temperature resistant adhesive. This high-temperature resistant adhesive is made of silicone, which has excellent high-temperature resistance and bonding performance, with a bonding strength ≥0.3MPa. This ensures a firm connection between the insulation board and the main board, stably maintaining the overall structure of the insulation board. The insulation board is 3-5mm thick, a thickness that ensures good thermal insulation performance while effectively supporting the compartmentalized structure without adding excessive weight.

[0009] Beneficial effects

[0010] This utility model provides a compartmentalized fireproof insulation board. Compared with the prior art, it has the following advantages:

[0011] 1. This compartmentalized fireproof insulation board, with its compartmentalized structure and fire-retardant coating forming multiple fire barriers, confines the fire to a single compartment, resulting in a high fire resistance rating; at the same time, the combination of heat insulation holes and insulation filling material results in a low thermal conductivity, balancing fire safety and energy-saving insulation requirements.

[0012] 2. This compartmentalized fireproof insulation board features a frame structure composed of double main panels and insulation boards, which has strong resistance to deformation. The silicone sealant ensures a firm connection. After removing redundant structures, it is lighter in weight, reducing transportation and installation costs. It also reduces vulnerable parts and extends service life. Attached Figure Description

[0022] The compartment 3 is filled with polystyrene foam board or polyurethane foam board, with a filling density of 20-30 kg / m³. The inner wall of the compartment 3 is coated with an intumescent fire-retardant coating with an expansion ratio ≥250% and made of water-based environmentally friendly material. The heat insulation holes 4 are circular with a diameter of 8-12 mm, and multiple heat insulation holes 4 are arranged in a matrix within the main body plate 1, with a hole spacing of 20-30 mm. There are 6-8 heat-conducting sheets 5, each with a thickness of 0.3-0.8 mm, and they are evenly distributed circumferentially along the inner wall of the heat insulation holes 4. The heat insulation board 2 is bonded to the main body plate 1 with high-temperature resistant adhesive made of silicone material, with a bonding strength ≥0.3 MPa, and the thickness of the heat insulation board 2 is 3-5 mm.

[0023] In this embodiment, the main body panel is manufactured as follows: Flame-retardant polystyrene granules are used to manufacture the main body panel 1 through injection molding. The thickness of the main body panel is controlled to be 60mm, the length to be 1200mm, and the width to be 600mm, ensuring that the main body panel has sufficient strength and flame-retardant properties. Circular heat-insulating holes 4 with a diameter of 10mm are drilled into the inner wall of the main body panel 1, distributed in a 4×5 matrix with a hole spacing of 25mm. Within each heat-insulating hole 4, three 0.5mm thick aluminum alloy heat-conducting sheets 5 are evenly installed by welding, with the heat-conducting sheets distributed at 120° circumferentially along the inner wall of the heat-insulating hole.

[0024] Insulation Board and Compartment Fabrication: Calcium silicate board is selected as insulation board 2. It is cut into 4mm thick sheets using a cutting device and arranged in a crisscross pattern. The spacing between the horizontal and vertical insulation boards is set to 200mm. Insulation board 2 is firmly bonded to the main board 1 using high-temperature resistant silicone adhesive, forming an independent compartment 3 with dimensions of 100mm × 100mm. Inside compartment 3, polyurethane foam board with a density of 25kg / m³ is used as insulation material.

The circular heat insulation holes 4 on the inner wall of the main plate 1 extend the heat conduction path, and together with the low thermal conductivity insulation material filled in the compartment 3, a high-efficiency heat insulation system is formed. The aluminum alloy heat-conducting sheet 5 balances the temperature of the main plate 1 and avoids local overheating. The heat insulation plate 2 and the fireproof coating on the inner wall of the compartment 3 form a fire barrier. In the event of a fire, the fireproof coating expands and blocks heat. The structure of the compartment 3 limits the spread of fire. The high-temperature resistant silicone adhesive ensures the stability of the overall structure, achieving a synergistic effect of heat insulation and fire resistance.
