[0027] Combine the following Figure 1 to Figure 4 The specific structure of the energy-saving and heat-insulating composite board of the utility model is described.

[0028] An embodiment of the utility model provides an energy-saving and heat-insulating composite board. Figure 1 As shown, it includes a vacuum insulation panel 1 and an organic thermal insulation panel 2. The organic thermal insulation panel 2 is provided with an assembly part and an installation part. The vacuum insulation panel 1 is compounded with the assembly part, and the energy-saving thermal insulation composite panel is constructed and installed through the installation part.

[0029] It can be understood that the energy-saving thermal insulation composite board of this embodiment can be used for the construction of low-energy wall systems and energy-saving renovation of existing walls. It mainly consists of two parts, namely, vacuum insulation board 1 and organic insulation board 2. By combining organic insulation board 2 with vacuum insulation board 1 in a certain board structure design, an insulation component that is easy to install is formed. The installation part of the energy-saving thermal insulation composite board is located on the organic insulation board 2, which can avoid damage caused by direct use of vacuum insulation board 1 during construction and installation, ensure the vacuum degree of vacuum insulation board 1, and improve the durability of energy-saving thermal insulation composite board. Moreover, since the use of vacuum insulation board 1 can ensure the excellent thermal performance of the component, and the combination of vacuum insulation board 1 and organic insulation board 2 can ensure the integrity of the construction component, while meeting the demand for high-efficiency energy-saving walls, the cost of the composite board is reduced.

[0030] In some specific embodiments of an energy-saving and heat-insulating composite panel of the utility model, an assembly groove 21 is provided on the organic heat-insulating board 2 to form an assembly portion, and the vacuum insulation panel 1 is fixed in the assembly groove 21. The depth of the assembly groove 21 is 3 to 5 mm greater than the thickness of the vacuum insulation panel 1; the thickness of the organic heat-insulating board 2 corresponding to the assembly groove 21 is not less than 20 mm. The vacuum insulation panel 1 is bonded and fixed in the assembly groove 21 by a polyurethane adhesive.

[0031] It can be understood that the vacuum insulation panel 1, as the energy-saving and heat-insulating composite panel of this embodiment, plays the role of the main component of low thermal conductivity and heat insulation, and occupies a large proportion of the space on the surface of the energy-saving and heat-insulating composite panel, that is, the assembly groove 21 on the surface of the organic insulation panel 2 occupies a large proportion. The vacuum insulation panel 1 is assembled in the assembly groove 21 and bonded by a polyurethane adhesive. The groove depth of the assembly groove 21 is greater than the thickness of the vacuum insulation panel 1, so that after the energy-saving and heat-insulating composite panel is installed on the wall, the vacuum insulation panel 1 and the wall are connected without a thermal bridge, and the low thermal conductivity of the vacuum insulation panel 1 in the energy-saving and heat-insulating composite panel structure is optimized. As an auxiliary component of the composite panel, the organic insulation panel 2 has a heat-insulating effect in addition to the overall structure being installed on the wall. The thickness of the organic insulation panel 2 corresponding to the assembly groove 21 is not less than 20 mm, so that the organic insulation panel 2 forms an effective heat-insulating cover on the wall.

[0032] In some specific examples, the assembly groove 21 has one, so that the organic insulation board 2 is constructed as a single C-shaped board structure, see Figure 2 shown. Figure 2 It is a cross-sectional structure of an energy-saving thermal insulation composite panel of a "single C panel". The energy-saving thermal insulation composite panel in this example can be used for energy-saving renovation of external and internal thermal insulation of exterior walls. During construction and installation, the vacuum insulation panel 1 is fixed in the assembly groove 21 of the organic thermal insulation panel 2 and bonded with a polyurethane adhesive. Then, the side of the organic thermal insulation panel 2 with the assembly groove 21 is attached to the wall surface, and the vacuum insulation panel 1 is fixed to the wall surface through the installation part of the organic thermal insulation panel 2. The vacuum insulation panel 1 faces the wall surface and there is a certain gap between the vacuum insulation panel 1 and the wall surface. The vacuum insulation panel 1 is connected to the wall without a thermal bridge, and low thermal conductivity insulation is performed. The outer insulation layer is formed by the organic thermal insulation panel 2, which further enhances the thermal insulation effect of the energy-saving thermal insulation composite panel on the wall.

[0033] In some other specific examples, there are two assembly grooves 21, and the two assembly grooves 21 are arranged on opposite surfaces of the organic thermal insulation board 2, so that the organic thermal insulation board 2 is constructed as a double C-shaped board structure. Figure 3 As shown, Figure 3It is a cross-sectional structure of an energy-saving thermal insulation composite board of a "double C board". The energy-saving thermal insulation composite board in this example can be used for energy-saving renovation of sandwich insulation walls or construction of low-energy wall systems. Taking sandwich insulation as an example, during construction and installation, an assembly groove 21 is respectively set on a group of opposite surfaces of the organic thermal insulation board 2 of the double C-type board structure, and the vacuum insulation board 1 is fixed in the assembly groove 21 and bonded by a polyurethane adhesive. The energy-saving thermal insulation composite board of the "double C board" in this example is installed in the sandwich layer, and low thermal conductivity insulation is performed on both sides of the sandwich layer through the two vacuum insulation boards 1 on the opposite sides. At the same time, the organic thermal insulation board 2 of the double C-type board structure also plays the role of installation and thermal insulation on both sides of the sandwich layer.

[0034] In some other specific embodiments of the energy-saving and heat-insulating composite board of the utility model, the organic heat-insulating board 2 is a graphite polystyrene board, an extruded board or a polyurethane board.

[0035] In some specific examples, energy-saving thermal insulation composite panels can be used as external wall insulation. In this case, the organic thermal insulation board 2 is a graphite polystyrene board or an extruded board, preferably a graphite polystyrene board. The graphite polystyrene board not only adds the flame retardant used in ordinary polystyrene board fire prevention (volatile at high temperatures), but also has stronger fire resistance, more stable and reliable due to the infrared reflectors mixed in the raw materials. Graphite polystyrene board is a product of the classic thermal insulation material expanded polystyrene further refined by chemical methods, with a thermal conductivity of ≤0.032. Its thermal insulation capacity is 30% higher than that of ordinary EPS, which helps to improve energy efficiency and reduce carbon dioxide emissions.

[0036] In other specific examples, the energy-saving thermal insulation composite board can be used as sandwich insulation. At this time, the organic thermal insulation board 2 is a graphite polystyrene board, an extruded board or a polyurethane board, preferably a polyurethane board. The polyurethane board has a low thermal conductivity, good thermal performance, and is moisture-proof and waterproof. The closed-pore rate of the polyurethane board is above 95%, which is a hydrophobic material. The thermal conductivity will not increase due to moisture absorption, and the wall will not seep water; it has strong anti-deformation ability, is not easy to crack, and has a stable and safe finish. The polyurethane material porosity structure of the polyurethane board is stable, which is basically a closed-cell structure. It not only has excellent thermal insulation performance, but also has good freeze-thaw resistance and sound absorption. The average life of the rigid foam polyurethane insulation structure can reach more than 30 years under normal use and maintenance conditions. It can be achieved that under normal use conditions during the life of the structure, it will not be damaged by dry, wet or electrochemical corrosion, as well as by external factors such as insect, fungus or algae growth or rodent damage. Moreover, since polyurethane sheets have excellent thermal insulation properties, while meeting the same thermal insulation requirements, the thickness of the building's exterior envelope can be reduced, thereby increasing the indoor usable area.

[0037] In some specific examples, when the energy-saving thermal insulation composite board is used as internal insulation, the organic thermal insulation board 2 is an extruded board. The extruded board is an extruded polystyrene thermal insulation board, which is a hard foam plastic board made by adding polystyrene resin as raw material, other raw and auxiliary materials and polymer content, heating and mixing by a special process, injecting a catalyst, and then continuously extruding and pressing to form. It has a perfect closed-cell honeycomb structure, which makes the extruded board have extremely low water absorption (almost no water absorption), moisture-proof, airtight, lightweight, corrosion-resistant, low thermal conductivity, high compressive resistance, aging resistance (almost no aging and decomposition phenomenon in normal use), long service life, low thermal conductivity and other excellent properties.

[0038] In some specific embodiments of the energy-saving and heat-insulating composite board of the utility model, see Figure 4 As shown, the edge of the organic thermal insulation board 2 is provided with an anchor hole 22 that penetrates the thickness direction of the organic thermal insulation board 2 to form a mounting portion; the anchor hole 22 is penetrated by an anchor plate 3, and the anchor nail on the anchor plate 3 penetrates the anchor hole 22 and is fixed to the wall to achieve the construction and installation of the energy-saving thermal insulation composite board. The hole diameter of the anchor hole 22 is 3 to 4 mm larger than the diameter of the anchor nail to form a bonding gap, and the bonding gap is filled with a polyurethane adhesive.

[0039] It should be understood that the energy-saving thermal insulation composite panels in this embodiment can be spliced ​​and used. Specifically, multiple energy-saving thermal insulation composite panels in this embodiment are arranged side by side, and the anchor holes 22 of two adjacent energy-saving thermal insulation composite panels are arranged closely to each other. Then, the anchor nails of the anchor plate 3 pass through the anchor holes 22 and are connected to the wall. The anchor plate 3 can splice the two adjacent energy-saving thermal insulation composite panels together. According to the requirements of the wall, the splicing is carried out appropriately to form a combined energy-saving thermal insulation composite panel of suitable area.

[0040] When it is necessary to anchor the energy-saving thermal insulation composite board on the wall, the anchor plate 3 is connected to the wall through the anchor hole 22 prefabricated in the organic thermal insulation board 2. The hole diameter of the anchor hole 22 is 3 to 4 mm larger than the anchor nail of the anchor plate 3. Before the anchor nail passes through the anchor hole 22 and is fixed to the wall, a polyurethane adhesive is pre-injected into the anchor hole 22, and then the anchor nail is inserted to connect with the wall.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
