Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of building materials, and specifically relates to a heat-insulating composite board. Background Art
[0002] In an exterior wall decoration structure, a heat-insulating board is usually added to achieve the purpose of heat insulation. Commonly used heat-insulating materials such as polyurethane boards belong to soft materials. Although such materials have good heat-insulating properties, they lack sufficient stiffness and strength. Therefore, it is necessary to develop a new type of board that can not only maintain excellent heat-insulating performance but also have high stiffness and strength to meet the requirements of the exterior wall structure for heat insulation while also being able to bear external loads. Content of the Utility Model
[0003] The utility model provides a heat-insulating composite board to solve the technical problems existing in the above-mentioned prior art.
[0004] To achieve the above purpose, the utility model adopts the following technical solution: a heat-insulating composite board, including a structural board, in which dense hollowings are arranged, soft heat-insulating materials are filled in the hollowings, and cement cloths are compounded on both sides of the structural board.
[0005] Preferably, the structural board is made of a metal material to ensure the strength of the structural board.
[0006] Preferably, the structural board is a honeycomb board, and the hollow structure of the honeycomb is stable.
[0007] Preferably, the structural board is an aluminum honeycomb board, which is light in weight, high in strength, environmentally friendly and fireproof.
[0008] Preferably, the heat-insulating material is polyurethane.
[0009] Preferably, the thickness of the structural board is 1 - 5 cm.
[0010] Preferably, the thickness of the cement cloth is 1 - 4 mm.
[0011] The beneficial effects of the utility model are as follows:
[0012] 1. The design of combining aluminum honeycomb and polyurethane complements each other. The addition of the aluminum honeycomb structure solves the problem of insufficient stiffness and strength of using only polyurethane as a heat-insulating board. And polyurethane has adhesiveness, is convenient to use, has strong bonding ability and uniform bonding, is not easy to generate voids, and can also play a role in strengthening the aluminum honeycomb board when filled in the aluminum honeycomb, making the aluminum honeycomb board have stronger seismic performance.
[0013] 2. As a high-quality thermal insulation and sound insulation material, polyurethane has excellent thermal insulation and sound insulation properties. Combined with honeycomb core materials, it forms enclosed small chambers, effectively hindering air flow, reducing sound wave propagation and heat conduction, and thus having even more excellent thermal insulation and sound insulation performance. Applying it to the exterior wall structure can significantly improve the building's thermal insulation and heat insulation effects and sound insulation ability, thereby creating a more comfortable and quiet living environment for the occupants.
[0014] 3. Composite cement cloth on both sides, which adjusts the surface flatness, increases the bonding force, and facilitates the combination of this thermal insulation composite board with the walls or exterior decorative boards or other functional boards on both sides. It also ensures that the overall structure is more stable.
[0015] 4. The aluminum honeycomb structure itself has good flame retardant properties, which is particularly important for polyurethane, an inflammable material. By filling polyurethane inside the aluminum honeycomb frame, the aluminum honeycomb structure can effectively isolate the flame, thus significantly improving the overall flame retardant performance of the thermal insulation board. This design not only improves the safety of the material but also ensures that the thermal insulation board can provide better fire protection when encountering a fire source. BRIEF DESCRIPTION OF THE DRAWINGS
[0016] Figure 1 It is a schematic structural diagram of the present utility model.
[0017] In the figure: 1. Aluminum honeycomb board; 2. Polyurethane; 3. Cement cloth. DETAILED DESCRIPTION OF THE EMBODIMENTS
[0018] The technical solutions of the present utility model will be further specifically described below through embodiments in conjunction with the drawings.
[0019] Embodiment: A thermal insulation composite board, as Figure 1 shown, includes an aluminum honeycomb board, with polyurethane filled inside the honeycomb, and cement cloth is composite on both sides of the aluminum honeycomb board. The thickness of the aluminum honeycomb board is generally 1 - 5 cm, specifically depending on requirements, preferably 1.5 - 2.5 cm. The side length of the honeycomb is generally about 1 cm, and the thickness of the cement cloth is 1 - 4 mm, preferably 1 mm.
[0020] Adopting the structure of filling polyurethane inside the aluminum honeycomb board takes into account both sound insulation, heat insulation and structural strength, and also has good fire performance. When used as an exterior wall sound insulation board, it is not easily squeezed and deformed. Composite cement cloth on both sides levels the surface, balances stress, makes the composite board more stable, increases the bonding force on both sides, and facilitates the combination with the objects on both sides. At the same time, for some scenarios with low requirements for the exterior wall, the composite board can act as the exterior wall surface by directly spraying and treating one side of the cement cloth for decoration.

It cannot be determined that the specific implementation of this utility model is only limited to the above descriptions. For those of ordinary skill in the technical field to which this patent pertains, without departing from the concept of this patent, several simple deductions or substitutions can be made, and all should be regarded as falling within the protection scope of this patent.
