Description

Technical Field

[0001] The present invention relates to the technical field of building decoration, and more particularly to a light-weight heat-insulating decorative board. Background Art

[0002] Energy conservation and emission reduction are common challenges faced by the world, and building energy conservation is a key component of this. External insulation systems for building exterior walls are an important means of achieving building energy conservation. There are many types of external insulation systems, among which decorative insulation panels are a common form used in buildings. Decorative insulation panels are composed of a decorative panel layer and an insulation layer, bonded together with an adhesive layer, and, if necessary, a base layer. The panel layer is typically a cement fiber board (or calcium silicate board), stone slab, or porcelain slab with a decorative coating. The disadvantages of these materials are their heavy weight and the high shear force caused by gravity. In actual projects, the panel layer is prone to falling off, causing safety accidents.

[0003] To overcome these shortcomings, technological advancements have led to the emergence of a variety of thin, lightweight panel layers in recent years. These include modified inorganic powder composite building facing sheets (JC / T311-2011, commonly referred to in the industry as soft porcelain, hereinafter referred to as soft porcelain), thin stone, metal or composite metal veneer panels, and thin ceramic panels, collectively referred to as lightweight panels. Composite panels composed of these lightweight panels and insulation panels using adhesives are called lightweight insulation decorative panels. According to current industry standards, atlases, and other relevant technical documents, insulation decorative panels must be installed using a combination of adhesive and anchoring. Metal fasteners, acting as anchors, must be inserted through the panel layer, transferring the panel load directly to the base wall. Traditional insulation decorative panels are thick enough to accommodate various anchoring grooves on the panel surface or sides. However, the thinness of lightweight insulation decorative panels makes them difficult to machine on the surface or sides, a major bottleneck hindering their market adoption.

[0004] Therefore, how to provide a lightweight thermal insulation decorative panel that is easy to anchor and install, has a simple structure, high strength, and is easy to install is a problem that technical personnel in this field urgently need to solve. Summary of the Invention

[0005] In view of this, the present invention provides a lightweight thermal insulation decorative panel, aiming to solve the above technical problems.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A light-weight heat-insulating decorative panel comprises a light-weight panel layer, a heat-insulating layer and a bottom plate layer bonded sequentially from top to bottom;

[0008] The bonding surface between the thermal insulation layer and the lightweight panel layer is provided with at least one mounting groove with both ends extending through the side wall of the thermal insulation layer;

[0009] A reinforcing mesh belt is sandwiched between the lightweight panel layer and the thermal insulation layer, and the reinforcing mesh belt is attached to the bottom wall and side walls of the installation groove and extends out of the installation groove to the surface of the thermal insulation layer;

[0010] An anchoring profile is fixed in the installation groove, and the anchoring profile is sandwiched between the lightweight panel layer and the reinforcing mesh belt.

[0011] Through the above technical solution, the present invention adopts lightweight panels, which greatly reduces the weight of the thermal insulation decorative panels, reduces shear force, and improves safety; an installation groove is opened in the insulation layer and a reinforcing mesh belt and an anchoring profile are pre-embedded. During construction and installation, the mechanical anchoring of the thermal insulation decorative panels and the wall can be conveniently and quickly achieved, thereby improving installation efficiency and reducing installation costs. While taking into account the advantages of lightweight panels, it solves the defect that lightweight panels are difficult to anchor. It has a simple structure, high strength, and is easy to install.

[0012] Preferably, in the above-mentioned lightweight thermal insulation decorative panel, bonding layers are formed between the lightweight panel layer and the thermal insulation layer, and between the thermal insulation layer and the base plate layer by an organic chemical adhesive or a cement-based adhesive, which can effectively achieve bonding between the layers.

[0013] Preferably, in the above-mentioned lightweight thermal insulation decorative board, the thermal insulation layer is one of extruded polystyrene board, expanded polystyrene board, modified expanded polystyrene board, rock wool board, foamed polyurethane board, foamed phenolic board, foamed ceramic board, foamed cement board and thermal insulation mortar, which can meet the use requirements of the thermal insulation layer.

[0014] Preferably, in the aforementioned lightweight thermal insulation decorative panel, the reinforcing mesh is a fiber mesh made of glass fiber, carbon fiber, or polyester fiber. This meets the tensile strength requirements of the reinforcing mesh. According to relevant industry standards, a combination of adhesive and anchoring is employed to ensure that, after the thermal insulation decorative panel is installed on the wall, the metal fasteners in the mounting slots transfer negative wind pressure from the wall to the reinforcing mesh, ensuring system safety.

[0015] Preferably, in the above-mentioned lightweight thermal insulation decorative panel, the mounting groove is opened horizontally and / or vertically on the surface of the thermal insulation layer, so that each cutout of the thermal insulation decorative panel has a mounting groove, which facilitates anchoring and installation.

[0016] Preferably, in the above-mentioned light-weight heat-insulating decorative panel, the anchoring profile is made of hard plastic or metal, or soft foamed plastic, or a combination of the above materials, so as to meet different usage requirements.

[0017] Preferably, in the above-mentioned lightweight thermal insulation decorative panel, the anchoring profile is a hard profile with a rectangular cross-section, or a hard profile with a U-shaped cross-section.

[0018] Preferably, in the above-mentioned lightweight thermal insulation decorative panel, the anchoring profile includes a hard profile with a U-shaped cross-section, and a soft foamed plastic wrapped inside the U-shaped hard profile.

[0019] Preferably, in the above-mentioned lightweight thermal insulation decorative panel, the reinforcing mesh belt is bonded and fixed to the installation groove and the anchoring profile, thereby improving the stability of the connection.

[0020] Preferably, in the above-mentioned lightweight thermal insulation decorative panel, the width of the installation groove is 25-30 mm and the depth is 3-5 mm, which meets the processing requirements of installation.

[0021] It can be seen from the above technical solutions that, compared with the prior art, the present invention provides a lightweight thermal insulation decorative panel with the following beneficial effects:

[0022] 1. The use of lightweight panels greatly reduces the weight of the insulation decorative panels, reduces shear force and improves safety.

[0023] 2. Open installation grooves in the insulation layer and pre-embed reinforced mesh belts and anchoring profiles. During construction and installation, the mechanical anchoring of the insulation decorative panels and the wall can be conveniently and quickly achieved, thereby improving installation efficiency and reducing installation costs.

[0024] 3. The installation groove can be opened horizontally and / or vertically to ensure that there is an anchoring profile in each cut.

[0025] 4. The width of the reinforced mesh belt is much larger than that of the anchoring profile, forming two wings, which increases the bonding area between the anchoring profile and the lightweight panel layer, greatly improving the integrity of the anchoring profile and the lightweight panel layer. The adhesive in the bonding layer passes through the gaps in the reinforced mesh belt and is combined with the upper and lower lightweight panel layers and the insulation layer, which can greatly improve the single-point anchoring force of the metal fastener.

[0026] 5. The present invention has low material cost, high production efficiency and low total cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0042] Example 1:

[0043] See attached Figure 1 To the attached Figure 5 , an embodiment of the present invention discloses a lightweight thermal insulation decorative panel, comprising a lightweight panel layer 1, a thermal insulation layer 2 and a bottom plate layer 3 bonded sequentially from top to bottom;

[0044] The bonding surface between the thermal insulation layer 2 and the lightweight panel layer 1 is provided with at least one mounting groove 4 with both ends penetrating to the side wall of the thermal insulation layer 2;

[0045] A reinforcement mesh belt 5 is sandwiched between the lightweight panel layer 1 and the insulation layer 2. The reinforcement mesh belt 5 is attached to the bottom wall and side walls of the installation groove 4 and extends out of the installation groove 4 to the surface of the insulation layer 2.

[0046] An anchoring profile 6 is fixed in the mounting groove 4 , and the anchoring profile 6 is sandwiched between the lightweight panel layer 1 and the reinforcing mesh belt 5 .

[0047] In order to further optimize the above technical solution, a bonding layer 7 is formed between the lightweight panel layer 1 and the thermal insulation layer 2, and between the thermal insulation layer 2 and the bottom plate layer 3 by an organic chemical adhesive or a cement-based adhesive.

[0048] In order to further optimize the above technical solution, the insulation layer 2 is one of extruded polystyrene board, expanded polystyrene board, modified expanded polystyrene board, rock wool board, foamed polyurethane board, foamed phenolic board, foamed ceramic board, foamed cement board and insulation mortar.

[0049] In order to further optimize the above technical solution, the reinforcing mesh belt 5 is a fiber mesh cloth; the material is glass fiber, carbon fiber or polyester fiber.

[0050] In order to further optimize the above technical solution, the installation groove 4 is opened horizontally and / or vertically on the surface of the thermal insulation layer 2.

[0051] In order to further optimize the above technical solution, the anchoring profile 6 is made of hard plastic material or metal material, or soft foam plastic, or a combination of the above materials.

[0052] In order to further optimize the above technical solution, the anchoring profile 6 is a hard profile with a rectangular cross-section, or a hard profile with a U-shaped cross-section.

[0053] In order to further optimize the above technical solution, the anchoring profile 6 includes a hard profile with a U-shaped cross-section, and a soft foamed plastic wrapped inside the U-shaped hard profile.

[0054] In order to further optimize the above technical solution, the reinforcement mesh belt 5 is bonded and fixed to the installation groove 4 and the anchoring profile 6 .

[0055] In order to further optimize the above technical solution, the width of the installation groove 4 is 25-30 mm and the depth is 3-5 mm.

[0056] The forming method of the light-weight thermal insulation decorative board provided by the present invention is:

[0057] The first step is to arrange and process the mounting groove 4 on one side of the insulation layer 2 according to the size of the anchor profile 6;

[0058] The second step is to place the reinforcing mesh belt 5 and the anchoring profile 6 in the installation groove 4 on the surface of the insulation layer 2. They can be placed directly or fixed in the installation groove 4 with an adhesive;

[0059] The third step is to apply glue on the back of the thermal insulation layer 2 and / or the lightweight panel layer 1. Depending on the type and thickness of the adhesive, it can be applied on both sides or on one side. Apply more glue at the position of the reinforcing mesh belt 5. After applying glue, the thermal insulation layer 2 and the lightweight panel layer 1 are bonded together.

[0060] In the fourth step, adhesive is applied to the other side of the insulation layer 2 and / or the back side of the bottom plate layer 3. Depending on the type and thickness of the adhesive, the adhesive can be applied on both sides or on one side. After the adhesive is applied, the insulation layer 2 and the bottom plate layer 3 are bonded together.

[0061] The fifth step is to maintain a certain pressure for a period of time to allow the adhesive to fully solidify. After reaching a certain strength, remove the pressure and the lightweight thermal insulation decorative board is formed.

[0062] Example 2:

[0063] like Figure 1 As shown, an anchoring profile 6 is prepared. The anchoring profile 6 is 30 mm wide and 3 mm thick. A mounting groove 4 is processed on one side of the insulation layer 2. The insulation layer 2 of this embodiment adopts a rock wool belt. The mounting groove 4 is 30 mm wide and 3 mm deep. A layer of adhesive is applied in the mounting groove 4, and then the reinforcing mesh belt 5 and the anchoring profile 6 are placed in the mounting groove 4. The lightweight panel layer 1 adopts a modified inorganic powder composite building facing sheet. Since the surface of the rock wool is relatively rough, it is necessary to apply polyurethane glue on the surface of the rock wool and the back of the facing sheet. The two are compounded together, and the polyurethane glue is cured to form a bonding layer 7. In order to further reduce the weight, cement cloth is used for the bottom plate layer 3. Polyurethane glue is applied on one side of the cement cloth and the other side of the insulation layer 2, and the two are compounded together. Keep it under the press for 24 hours, wait for the polyurethane glue to fully cure and reach sufficient strength, and then the lightweight insulation decorative panel of this embodiment is formed.

[0064] Example 3:

[0065] like Figure 1 As shown, prepare the anchoring profile 6, which has a width of 25 mm and a thickness of 5 mm. Process the mounting groove 4 on one side of the thermal insulation layer 2. The thermal insulation layer 2 of this embodiment adopts expanded polystyrene foam board, and the mounting groove 4 has a width of 25 mm and a depth of 5 mm. Then put the reinforcing mesh belt 5 and the anchoring profile 6 into the mounting groove 4. The lightweight panel layer 1 adopts thin stone. Since the backs of the expanded polystyrene foam board and the thin stone are smooth, it is only necessary to apply marble glue on the back plate of the thin stone. The two are compounded together, and the marble glue forms a bonding layer 7 after curing. Due to the good strength and integrity of the expanded polystyrene board, the bottom plate layer 3 is not required in this embodiment. After being kept under the press for 12 hours and waiting for the marble glue to fully cure and reach sufficient strength, the lightweight thermal insulation decorative panel of this embodiment is formed.
