Description

Technical Field

[0001] The invention relates to the field of thermal insulation decoration, in particular to a polyurethane thermal insulation decoration integrated board. Background Art

[0002] Building codes require that the exterior walls of buildings should be insulated to reduce energy consumption and meet energy-saving requirements. In the current construction industry, after the structural wall is completed, mortar or similar adhesives are used to stick insulation materials to the outside of the wall to form an insulation layer, and then a decorative layer is pasted on the outside of the insulation layer. After the decorative layer of the exterior wall has been exposed to wind and sun for a long time, cracks or falls off. For the sake of aesthetics, the decorative layer of the exterior wall of the building needs to be repaired. Since the decorative layer and the insulation layer are bonded, when the decorative layer is peeled off, the insulation layer will be damaged, resulting in insulation failure, which will increase labor costs and working time. The common insulation material now is polyurethane insulation board. The insulation board of this material is light in weight, low in thermal conductivity, and hydrophobic, but has limited fire resistance. Under high temperature conditions, it will shrink, which will affect the safety of the building's exterior wall and the quality of the building. Summary of the invention

[0003] In view of the above problems, the present invention provides a polyurethane thermal insulation and decorative integrated panel, which has the advantages that the decorative layer and the thermal insulation layer can be detachably installed and disassembled independently and has high fire resistance.

[0004] The technical solution of the present invention is:

[0005] A polyurethane thermal insulation and decorative integrated panel comprises a thermal insulation layer, a decorative layer and a connecting piece, wherein the thermal insulation layer and the decorative layer are connected via the connecting piece, the thermal insulation layer is polyurethane foam doped with basalt fiber, the connecting piece is an L-shaped screw, the connecting piece comprises a screw segment and a bare rod segment perpendicular to the screw segment, the screw segment passes through the thermal insulation layer, and the bare rod segment is connected to the decorative layer.

[0006] The working principle of the above technical solution is as follows:

[0007] The insulation layer and the decorative layer are connected by a connector, which is an L-shaped screw. When in use, the insulation layer is first fixed to the exterior wall through the connector, and then the decorative layer is hung on the L-shaped screw. When the decorative layer has problems and needs to be replaced, the decorative layer can be directly removed without damaging the insulation layer. The modular connection structure is used to achieve rapid disassembly and installation of the building exterior wall. The operation is simple and easy to use. At the same time, basalt fiber is added to the polyurethane foam to improve the fire resistance and thermal insulation effect of the insulation layer.

[0008] In a further technical solution, a fastening nut is provided on a side of the screw segment away from the decorative layer.

[0009] A fastening nut is arranged on the side of the screw rod away from the decorative layer. The bolt structure can increase the density between the insulation layer and the wall, and increase the stability of the connection between the insulation layer and the wall.

[0010] In a further technical solution, an L-shaped groove corresponding to the connecting piece is provided on one side of the decorative layer close to the thermal insulation layer.

[0011] An L-shaped groove corresponding to the connecting piece is arranged on the side of the decorative layer close to the insulation layer, and the decorative layer can be connected to the L-shaped screw through the L-shaped groove. The bare rod section of the L-shaped screw is inserted into the groove to achieve a stable connection with the decorative layer, thereby improving the stability of the connection of the decorative layer.

[0012] In a further technical solution, a waterproof coating and a light-shielding film are sequentially arranged on the side of the thermal insulation layer that contacts the decorative layer and faces the decorative layer.

[0013] Providing a waterproof coating and a shading film on the insulation layer can prevent the insulation layer from being impacted by rain and exposed to sunlight when the outer decorative layer fails or is removed, thereby affecting the insulation quality and wall quality.

[0014] In a further technical solution, two opposite side surfaces of the four side surfaces of the decorative layer relative to the two largest surfaces thereof are respectively provided with protrusions and grooves corresponding to the protrusions.

[0015] In a further technical solution, the four sides of the thermal insulation layer relative to its two largest surfaces are provided with a fire retardant coating.

[0016] Providing a fire-proof coating on the insulation layer can further improve the fire-proof ability of the polyurethane insulation board.

[0017] In a further technical solution, the screw segment is vertically connected to the insulation layer.

[0018] The screw rod section is parallel to the ground, the smooth rod section is perpendicular to the ground, and the screw rod and the smooth rod form an L-shaped structure, which can ensure that the decorative layer will not fall off and improve the installation stability of the decorative layer.

[0019] In a further technical solution, the connecting piece is movably connected to the thermal insulation layer.

[0020] The connecting piece is movably connected to the thermal insulation layer, so that the compactness of the thermal insulation layer and the wall can be adjusted by adjusting the connecting piece, thereby ensuring the stability and reliability of the connection of the thermal insulation layer.

[0021] In a further technical solution, an anti-penetration sealing ring is provided at the connection between the connecting piece and the thermal insulation layer.

[0022] Since the connector passes through the insulation layer, there must be a through hole in the insulation layer. The connector is connected to the insulation layer. By providing an anti-leakage sealing ring at the connection, it can be ensured that there will be no leakage at the connection and the connector will not shake in the insulation layer, thereby improving the stability of the connection.

[0023] In a further technical solution, an anti-oxidation coating is provided on a surface of the decorative layer away from the thermal insulation layer.

[0024] Providing an anti-oxidation coating on the surface of the decorative layer away from the thermal insulation layer can slow down the oxidation rate of the decorative layer surface and increase the service life of the decorative layer.

[0025] The beneficial effects of the present invention are:

[0026] 1. The decorative layer and the insulation layer are connected by an L-shaped screw-shaped connector. The decorative layer and the insulation layer can be installed and disassembled separately, with high connection reliability and high installation flexibility. At the same time, basalt fiber is added to the polyurethane foam to improve the fireproof ability and insulation effect of the insulation board;

[0027] 2. A fastening nut is arranged on the other side of the connector, and the density of the connection between the insulation layer and the wall can be adjusted by the fastening nut. When the insulation layer shrinks, the density between the insulation layer and the wall can be increased by adjusting the fastening nut, thereby improving the reliability of the connection between the insulation layer and the wall;

[0028] 3. An L-shaped groove corresponding to the connector is provided on the side of the decorative layer close to the insulation layer. The L-shaped groove is connected to the connector to improve the reliability of the connection while maintaining the appearance of the decorative layer;

[0029] 4. A waterproof coating and a light-shielding film are provided on the side of the insulation layer that contacts the decorative layer, which can prevent the insulation layer from failing due to sun exposure or rain when the decorative layer is removed or not installed;

[0030] 5. A protrusion is provided on the left side of the decorative layer, and a groove corresponding to the protrusion is provided on the right side. Adjacent decorative panels are connected by the cooperation of the protrusion and the groove, which can ensure the stability and reliability of the connection of the decorative panels;

[0031] 6. A fireproof coating is provided on the surface of the insulation layer that is not in contact with the decorative layer, which can further improve the fireproof effect of the insulation layer;
