Description

Technical Field

[0001] The utility model relates to the field of building materials, in particular to a vacuum thermal insulation decorative integrated board for nearly zero energy consumption buildings. Background Art

[0002] Vacuum insulation decorative integrated board is a new type of building material, which combines vacuum insulation technology and decorative integrated design concept. The insulation layer of the vacuum board can effectively reduce heat conduction and improve the thermal insulation performance of the building, while the decorative layer on the outer surface can meet the needs of the building appearance and beautify the building appearance.

[0003] The existing vacuum insulation decorative integrated panels have the following main problems during production, storage, transportation and construction: (1) The vacuum panels are easily damaged and leak; (2) During construction, when angle brackets are needed for fixing, they are likely to damage the vacuum panels when they extend to the side of the vacuum panels, causing leakage and reducing the insulation performance.

[0004] CN 219298494U discloses a vacuum insulation assembly board, which includes a rectangular core board and a polyurethane layer wrapped around the rectangular core board. The thickness of the vacuum insulation board does not exceed 30 mm, the thickness of the polyurethane layer wrapped around the front and rear sides of the rectangular core board is 20 mm, and the thickness of the polyurethane layer wrapped around the four side walls of the rectangular core board is 10 mm. However, the structure has the following shortcomings: (1) The thickness of the polyurethane layer is too large, which will greatly reduce the fireproof performance of the vacuum board; (2) The thickness of the insulation layer of the vacuum board is small, not exceeding 30 mm. Although it can reduce the building area, the insulation effect is slightly poor and it is difficult to meet the requirements of near-zero energy consumption buildings; (3) The vacuum board is a splicing structure, not combined with a decorative board as a thermal insulation decorative structure, and the finishing layer needs to be constructed again.

[0005] In summary, the present application urgently needs to design a vacuum insulation decorative integrated panel for near-zero energy consumption buildings to solve the above problems. Utility Model Content

[0008] Furthermore, the thickness of the insulation layer of the vacuum panel is 30-60 mm.

[0009] Furthermore, the thickness of the insulation layer of the vacuum panel is 50 mm.

[0010] Furthermore, the polyurethane layer located on the four sides extends to the edge of the vacuum panel facing the decorative panel to form an edge wrapping.

[0011] Furthermore, a corner fixing hole for fixing the corner bracket is provided on the side of the decorative plate, and the corner bracket extends to the position of the polyurethane layer on the side of the vacuum plate away from the decorative plate.

[0019] Figure 2 It is a schematic diagram of the structure of the vacuum plate of the utility model embodiment. DETAILED DESCRIPTION

[0020] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0021] like Figure 1 and Figure 2 As shown: A vacuum insulation decorative integrated panel for a near-zero energy building, comprising a vacuum panel 1 and a decorative panel 2 connected to the vacuum panel 1 as a whole; the four sides of the vacuum panel 1 and the side away from the decorative panel are wrapped with a polyurethane layer 3, and the thickness of the polyurethane layer 3 is 5-10 mm.

[0022] In this embodiment, the thickness of the polyurethane layer is set to 5~10mm. On the one hand, if the thickness of the polyurethane layer is too large, the fireproof effect of the entire board will be poor, because the vacuum board itself is a flame-retardant material. If the thickness of the polyurethane layer is too large, it will be easily ignited, resulting in a significant reduction in fireproof performance; therefore, this embodiment selects a polyurethane layer with a thickness of 5~10mm, which can achieve near-zero energy consumption of the building on the basis of ensuring fireproof performance. In addition, by setting a foamed polyurethane layer to wrap the side of the vacuum board away from the decorative board, a large area of ​​polyurethane protection can prevent the vacuum board from being damaged during mortar bonding during construction; and by setting polyurethane protection around the vacuum board, the corner code fixing can be prevented from damaging the vacuum board during construction; it can be said that the polyurethane wrapping protection of this embodiment can increase the surface strength of the vacuum board to a certain extent, making it convenient for the vacuum board to be produced, stacked, transported, and not easily damaged during construction. Preferably, the thickness of the polyurethane layer is 5mm.

[0023] Furthermore, if the vacuum panel is not wrapped with a polyurethane layer, directly compounding it with the decorative panel will easily lead to air leakage, while adding a polyurethane layer can significantly reduce the occurrence of air leakage.

[0024] In this embodiment, the thickness of the insulation layer of the vacuum panel 1 is 30-60 mm, and it is a Class A fireproof material. If the thickness of the insulation layer is too small, it is easy to reduce the thermal insulation performance. If the thickness is too large, it is easy to increase the occupancy rate of the insulation layer to the building area. The present invention preferably has a thickness of 50 mm, so that the vacuum panel can achieve near-zero energy consumption and can also minimize the occupancy rate of the insulation to the building area when the building is insulated. Moreover, the heat transfer coefficient of the 50 mm vacuum panel is 0.12 W / m 2 K, equivalent to the thermal insulation performance of 350mm rock wool, can greatly reduce the insulation thickness and reduce the wall load.

[0025] In this embodiment, the polyurethane layer 3 located on the periphery extends to the edge of the vacuum panel facing the decorative panel to form an edge wrapping to improve the sealing and thermal insulation performance of the building structure and reduce the possibility of air leakage.

[0026] In this embodiment, the thickness of the polyurethane layer 3 at any position of the vacuum panel is the same, that is, the thickness of the polyurethane layer on all sides of the vacuum panel 1 and on the side away from the decorative panel 2 is the same, which can ensure that the entire structure is balanced in terms of thermal insulation, improve the energy efficiency of the building and reduce energy loss.

[0027] In this embodiment, the outer layer of the decorative board 2 is a metal finishing layer, and the inner layer is a heat-insulating material. The side of the decorative board 2 is provided with a corner bracket fixing hole 21 for fixing the corner bracket, and the corner bracket is connected to the corner bracket fixing hole 21, and the corner bracket also extends to the polyurethane layer position on the side of the vacuum board away from the decorative board, so as to facilitate the fixed connection with the wall, thereby preventing the corner bracket from damaging the vacuum board during the construction process, ensuring the vacuum insulation performance of the vacuum board, and reducing air leakage.

[0028] In this embodiment, the decorative panel 2 and the vacuum panel 1 are bonded together to form an integrated insulation and decoration panel, which is particularly suitable for promotion in the northern insulation market. It can not only improve the insulation performance, but also minimize the occupancy rate of insulation on the building area.

[0029] To sum up, on the one hand, the utility model can greatly improve the thermal insulation performance and achieve near-zero energy consumption of buildings, which is particularly suitable for promotion in the northern thermal insulation market and can minimize the occupancy rate of thermal insulation on building area; on the other hand, during the construction process, it can prevent the damage to the vacuum panels caused by the corner fixation and improve the strength of the surface of the vacuum panels, making it convenient for the vacuum panels to be produced, stacked and transported without being easily damaged.
