Description

Technical Field

[0001] This utility model relates to a composite building material, specifically a thermal insulation and decorative composite board with a coating finish, belonging to the technical field of integrated thermal insulation and decoration of building exterior walls. Background Technology

[0002] With the continuous improvement of building energy efficiency standards, external wall insulation systems have become an important development direction for building exterior wall energy conservation and insulation. Traditional external wall insulation systems typically employ on-site construction methods, adhering insulation materials to the exterior surface of the building wall before applying plaster and paint finishes. This approach suffers from problems such as long construction cycles, unstable quality, susceptibility to hollowing, cracking, and leakage, and generally mediocre facade decoration effects. In contrast, the thermal insulation and decorative composite panel external wall insulation system offers advantages such as fast construction speed, safety and reliability, excellent decorative effects, and high building quality, leading to its increasingly widespread application in building engineering.

[0003] Currently, the market offers various types of thermal insulation and decorative composite panels, including inorganic non-metallic panels, stone panels, and metal panels. Among these, inorganic metal panels with a coating finish have the largest market share. The panels of these coated inorganic metal panels typically use fiber-reinforced calcium silicate board or fiber-reinforced cement board, with a panel thickness of approximately 8mm. While these panels offer good decorative effects, they suffer from drawbacks such as high mass per unit area, inconvenient and unreliable auxiliary anchoring installation, and high costs.

[0004] Therefore, there is an urgent need for a coating-finished thermal insulation composite board that has good decorative effect, reasonable structure, convenient installation, light weight and moderate cost to meet the needs of integrated thermal insulation and decoration in building energy-saving projects. Utility Model Content

[0005] The purpose of this utility model is to provide a thermal insulation and decorative composite board with a coating finish, which solves the problems of large unit area mass, inconvenient and unreliable installation, and high cost of inorganic non-metallic panel thermal insulation and decorative boards with coating finishes in the background art.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] A thermal insulation and decorative composite panel with a coating finish, comprising, from top to bottom:

[0008] The coating finish layer, flexible crack-resistant mortar sheet layer, insulation board layer, and base layer are all included.

[0009] The flexible crack-resistant mortar sheet layer and the insulation board layer are bonded together with an adhesive; the insulation board layer and the base lining layer are bonded together with an adhesive.

[0010] The flexible crack-resistant mortar sheet layer has an alkali-resistant fiberglass mesh built in; the insulation board layer is provided with a keel and at least one layer of reinforcing mesh.

[0011] The core of this invention lies in its multi-layered structural design, featuring a flexible, crack-resistant mortar sheet layer and reinforcing structures in key layers. The outermost coating layer provides a decorative effect; the flexible, crack-resistant mortar sheet layer incorporates alkali-resistant fiberglass mesh to effectively prevent cracking; the keel and reinforcing mesh within the insulation board layer significantly improve the overall integrity and rigidity of the board, enhancing the reliability of anchoring installation; the bottom lining layer reinforces the rigidity of the composite board and improves the reliability of its bonding installation. All layers are connected by appropriate adhesives, forming a composite board with strong integrity and excellent overall performance.

[0012] The present invention also provides a thermal insulation and decorative composite panel, which comprises, from top to bottom: a flexible ceramic veneer layer, a thermal insulation board layer, and a base layer, wherein the thermal insulation board layer and the base layer are bonded together by an adhesive; the thermal insulation board layer is provided with a keel and at least one layer of reinforcing mesh; the flexible ceramic veneer layer is a modified inorganic powder composite building veneer sheet.

[0013] Preferably, the adhesive used is made from polymeric adhesives, polyurethane, or bonding mortar. These adhesive materials have excellent bonding strength and durability, forming a strong bond between the coating finish layer and the insulation board layer, ensuring that the two layers will not separate or detach during long-term use, thus improving the overall service life of the product.

[0014] Preferably, the insulation board is selected from inorganic insulation board or organic-inorganic composite insulation board.

[0015] Preferably, the reinforcing mesh is fiberglass mesh or steel wire mesh. Fiberglass mesh is lightweight, high-strength, and alkali-resistant, effectively enhancing the crack resistance and overall stability of the insulation board layer; steel wire mesh provides higher mechanical strength and impact resistance, making it particularly suitable for applications requiring high strength.

[0016] Preferably, the coating finish layer is a multi-layer architectural coating finish layer, a multi-colored architectural coating finish layer, or a synthetic resin emulsion sand-textured architectural coating finish layer formed on a flexible crack-resistant mortar sheet layer; the thickness of the flexible crack-resistant mortar sheet layer is 2.5-4 mm. The flexible crack-resistant mortar sheet layer is manufactured in a factory.

[0017] Preferably, the insulation board is a Class A fire-resistant insulation board with a thickness of 20-200mm. This 20-200mm thickness range allows for flexible adjustment based on different climate zones and building energy efficiency requirements, meeting the insulation needs of various building types.

[0018] Preferably, the keel is made of aluminum alloy profiles, hot-dip galvanized steel sheets, or fiberglass, with several keels evenly distributed horizontally within the insulation board layer. Aluminum alloy profile keels are lightweight and corrosion-resistant; hot-dip galvanized steel sheet keels offer high strength and good corrosion resistance. The horizontally evenly distributed keel design within the insulation board layer effectively enhances the integrity of the integrated panel, improves its bending and deformation resistance, and facilitates connection and fixation to the main building structure.

[0019] Preferably, the keel cross-sectional shape is C-shaped, U-shaped, rectangular, or U-shaped with folded edges, with a wall thickness of 0.8~3.0mm, a width of 20~35mm, and a height of 5~15mm. C-shaped and U-shaped keels are lightweight and high-strength; rectangular keels have a simple structure and are easy to process; U-shaped keels with folded edges increase the contact area with the insulation material and improve the bonding performance.

[0020] Preferably, the insulation board layer is provided with two layers of reinforcing mesh, and the keel is placed on the reinforcing mesh that is closer to the flexible crack-resistant mortar sheet layer, with its bottom adjacent to the reinforcing mesh. This multi-layered reinforcement structure with two layers of reinforcing mesh significantly improves the overall strength and deformation resistance of the insulation board layer. The U-shaped keel structure with folded edges increases the contact area with the insulation material, improving the bonding strength. Placing the keel on the reinforcing mesh close to the coating finish layer, with the U-shaped bottom adjacent to the reinforcing mesh, forms a composite structural system with strong integrity and a clear force transmission path. This enhances the overall rigidity of the integrated board and improves its wind pressure resistance, ensuring the stability and safety of the integrated board during long-term use.

[0021] The beneficial effects of this utility model are:

[0022] 1. This utility model discloses a thermal insulation and decorative composite board with a coating finish. Through reasonable multi-layer structure design and material selection, it adopts a flexible crack-resistant mortar sheet layer, which is lighter and has a smaller unit area weight than the coating finish calcium silicate board panel thermal insulation and decorative board, thereby reducing costs, reducing the burden on the building structure, and improving safety.

[0023] 2. The keel design of this utility model is flexible and can be set inside or on the surface of the insulation board, which facilitates auxiliary anchoring and installation and is safe and reliable.

[0024] 3. The flexible crack-resistant mortar sheet layer of this utility model has an alkali-resistant fiberglass mesh cloth built in, which can effectively absorb and disperse stress, prevent the coating surface layer from cracking, and achieve a good decorative effect.

[0025] 4. The insulation board layer of this utility model is equipped with a keel and reinforcing mesh, and a bottom lining, which greatly improves the integrity and rigidity of the composite board, facilitates handling, and improves the reliability of adhesive installation.

[0030] The technical solution of this utility model will be further described in detail below through specific embodiments. It should be understood that the implementation of this utility model is not limited to the following embodiments, and any modifications and / or alterations made to this utility model will fall within the protection scope of this utility model.

[0031] In this invention, unless otherwise specified, all parts and percentages are by weight, and the equipment and raw materials used are commercially available or commonly used in the field. Unless otherwise specified, the methods in the following embodiments are conventional methods in the field.

[0032] Reference Figure 1 As shown, the thermal insulation decorative composite panel with coating finish of this utility model includes, from top to bottom: a coating finish layer 1, a flexible crack-resistant mortar sheet layer 2, a thermal insulation board layer 3, and a base layer 4. The flexible crack-resistant mortar sheet layer and the thermal insulation board layer are bonded together with an adhesive to form a first bonding layer 7; the thermal insulation board layer and the base layer are bonded together with an adhesive to form a second bonding layer 8.

[0033] The coating finish layer 1 is the outermost layer of the composite panel, directly exposed to the external environment, primarily providing decorative effects and basic protective functions. Depending on different decorative needs, multi-layer architectural coatings, multi-color architectural coatings, or synthetic resin emulsion sand-textured architectural coatings can be selected.

[0034] The thickness of the flexible crack-resistant mortar sheet layer 2 is 2.5-4mm. This layer contains an embedded alkali-resistant fiberglass mesh, exhibiting good alkali resistance, tensile strength, and dimensional stability. The main function of the flexible crack-resistant mortar sheet layer is to prevent surface cracking caused by factors such as temperature changes and external forces. The flexible crack-resistant mortar sheet layer is a type of crack-resistant mortar sheet.

[0035] Insulation layer 3 is the main component providing thermal performance, and its thickness can be selected from 20-100mm depending on different insulation requirements. It is preferable to use Class A fire-resistant insulation boards, such as inorganic insulation materials like rock wool boards and glass wool boards, or organic-inorganic composite insulation boards such as modified EPS and XPS.

[0036] The key structural feature of the insulation board layer lies in the installation of keel 5 and at least one layer of reinforcing mesh 6. There are two ways to install the keel 5: one is to install it inside the insulation board (e.g., ...). Figure 1 As shown), it is evenly distributed parallel to the horizontal direction of the insulation layer; another type is set on the surface of the insulation board (such as...). Figure 2 As shown in the figure, it can be directly bonded to the surface of the insulation board or fixed by mechanical means.

[0037] The keel can be made of aluminum alloy profiles, hot-dip galvanized steel sheets or fiberglass materials. The cross-sectional shape can be C-shaped, U-shaped, rectangular or U-shaped with folded edges. The keel wall thickness is 0.8-3.0mm, the width is 20-35mm, and the height is 5-15mm.

[0038] like Figure 3 As shown, two layers of reinforcing mesh are installed in the insulation board layer, located at the upper part (reinforcing mesh 6) and the lower part (second reinforcing mesh 9) of the insulation board, respectively. The reinforcing mesh can be made of fiberglass mesh or steel wire mesh.

[0039] Specifically, when the keel is installed inside the insulation board layer, the keel 5 is positioned on top of the upper reinforcing mesh, which is closer to the flexible crack-resistant mortar sheet layer 2, and the bottom of the keel is adjacent to the reinforcing mesh. The upper reinforcing mesh is located approximately 5-10 mm from the upper surface of the insulation board, and the lower reinforcing mesh is located approximately 5-10 mm from the lower surface of the insulation board. The two reinforcing meshes work together to form a three-dimensional reinforced structure, significantly improving the bending strength and impact resistance of the insulation board.

[0040] When the keel is installed on the surface of the insulation board, the keel directly contacts the upper surface of the insulation board and is firmly connected to the insulation board by adhesive or mechanical fixing. This installation method facilitates the keel's auxiliary anchoring, and the composite board can be fixed to the building wall through the keel during the installation process, which is safe and reliable.

[0041] The bottom lining layer 4 is the lowest layer of the composite board, and cement fiber felt is preferably used as the bottom lining material. The main function of the bottom lining layer is to prevent the insulation material from getting damp and damaged, while also enhancing the overall rigidity of the board.

[0042] Adhesives can be polymer adhesives, polyurethane adhesives, or bonding mortars. The flexible crack-resistant mortar sheet layer 2 and the insulation board layer 3 are typically bonded together using polymer adhesives or polyurethane adhesives; the insulation board layer 3 and the base lining layer 4 can be bonded together using bonding mortars or polymer adhesives.

[0043] In addition, this utility model also provides a thermal insulation and decorative composite board, which uses modified inorganic powder composite building veneer sheet (soft porcelain veneer layer) to replace the aforementioned paint veneer layer 1 and flexible crack-resistant mortar sheet layer 2, and also has the same advantages.

[0044] This utility model's coated thermal insulation and decorative composite board has a reasonable overall structure and high strength. In particular, the flexible crack-resistant mortar sheet layer design makes its unit area mass smaller than that of traditional coated calcium silicate board thermal insulation and decorative boards. Meanwhile, the addition of a base layer improves the overall integrity of the composite board; the flexible installation of the keel (either inside or on the surface of the insulation board) makes the installation of the board more convenient, safe, and reliable; and the variety of coating options allows for a richer and more diverse decorative effect.
