[0039] Embodiment 1
[0040] As Figure 1 shown, an inorganic composite inner thermal insulation board comprises a non-woven fabric 1, an aerogel cotton felt 2, a thermal insulation and fireproof layer, and a finish 4 arranged in sequence.
[0041] The thermal insulation and fireproof layer comprises a plurality of glass fiber cotton boards 5 and vacuum thermal insulation boards, all the vacuum thermal insulation boards are arranged along the width or length direction of the thermal insulation and fireproof layer, and the glass fiber cotton boards 5 are arranged at the edges of the vacuum thermal insulation boards.
[0042] Vacuum thermal insulation board: mainly used in occasions requiring high-efficiency insulation, such as building exterior walls, refrigeration equipment, etc. Its thermal conductivity is low, only 0.002-0.004 W / (m·K), which is 1 / 10 of the thermal conductivity of traditional insulation materials. The use of vacuum thermal insulation boards can improve the insulation effect and fireproof performance under the same conditions, thereby reducing the wall thickness. However, the vacuum thermal insulation board cannot be cut, which may cause the problem of not being able to adapt to the wall surface in actual use, and the vacuum thermal insulation board cannot be nailed, which makes it difficult to stably fix the vacuum thermal insulation board with the wall keel 10. By arranging the glass fiber cotton board 5 at the edge of the vacuum thermal insulation board, the edge of the vacuum thermal insulation board is replaced by the glass fiber cotton board 5. Under the condition of ensuring the improvement of the heat insulation capacity, the glass fiber cotton board 5 can be cut and nailed, thereby enabling the cutting to adapt to more wall surfaces, and enabling stable fixation with the keel 10, thereby ensuring the stability of installation.
[0043] Optionally, the thickness of the vacuum thermal insulation board and the glass fiber cotton board 5 is 15-25 mm; the bulk density of the vacuum thermal insulation board is ≥200 kg / m 3 , and the thermal conductivity is ≤0.006 W / m 2 ·K. The bulk density of the high-strength glass fiber cotton board 5 is 100-120 kg / m 3 , and the thermal conductivity is ≤0.035 W / m 2 ·K.
[0044] As a preferred embodiment, the vacuum insulation board is a VIP vacuum insulation board 3, which is typically used in applications requiring higher insulation performance, such as ultra-thin insulation materials and green buildings. It has a lower thermal conductivity, reaching 0.0025 W / (m·K), which is 6 to 8 times that of conventional polystyrene boards, 4 to 5 times that of extruded polystyrene boards, and 3.5 times that of polyurethane. In addition, the vacuum insulation board 3 also features ultra-thin thickness, high fire resistance rating A1, and lightweight materials, resulting in better insulation performance.
[0045] The non-woven fabric 1 covers one side of the thermal insulation and fireproof layer to protect the thermal insulation and fireproof layer; optionally, the thickness of the non-woven fabric 1 is 1mm-2mm.
[0046] The decorative surface 4 covers the other side of the thermal insulation and fireproof layer to protect it; optionally, the decorative surface 4 is a cement fiberboard, calcium silicate board or magnesium crystal decorative board, and the thickness of the decorative surface 4 is 5mm-10mm.
[0047] The decorative surface 4, the heat insulation and fireproof layer, and the non-woven fabric 1 are an integrated structure.
[0048] Aerogel cotton felt 2 is placed between the nonwoven fabric 1 and the thermal insulation and fireproof layer. Aerogel cotton felt 2 can reduce the thermal bridging effect between the vacuum insulation board and the fiberglass cotton board 5.
[0049] In a preferred embodiment, the nonwoven fabric 1 wraps the aerogel cotton felt 2 to prevent the aerogel cotton felt 2 from shedding powder. The thickness of the aerogel cotton felt 2 is 4mm-6mm, and the aerogel cotton felt 2, the vacuum insulation board, and the decorative surface 4 are all staggered, which can reduce the impact of gaps on the insulation effect of the wall panel and effectively reduce the thermal bridging effect between the vacuum insulation board and the fiberglass cotton board 5. The calculation results of the linear heat transfer coefficient are shown in Table 1 and... Figures 8-10 As shown, Figures 8-10 The diagrams showing the temperature distribution of the inorganic composite insulation boards in Structures 1, 2, and 3 are presented respectively. It can be calculated that adding the aerogel felt layer reduces the heat transfer coefficient along the structure line from 0.03 W / (m·K) to 0.02 W / (m·K). Furthermore, the thickness of the aerogel felt 2 can be adjusted or eliminated based on the project's energy-saving requirements.

[0051]
[0052] In this embodiment, the decorative surface 4 and the thermal insulation and fireproof layer can be bonded together with adhesive, the thermal insulation and fireproof layer and the aerogel cotton felt 2 can be bonded together with adhesive, and the aerogel cotton felt 2 and the non-woven fabric 1 can be bonded together with adhesive, making the operation more convenient. Furthermore, the vacuum insulation board includes vacuum insulation material and an outer aluminum foil cover. The outer aluminum foil cover is relatively smooth, resulting in poor adhesion to the non-woven fabric 1. The aerogel cotton felt 2 facilitates the bonding of the non-woven fabric 1 and the thermal insulation and fireproof layer together.
[0053] In some embodiments, the thermal insulation and fireproof layer is divided into several basic units along its length or width, such as... Figures 2-5 As shown, each basic unit includes a vacuum insulation board and fiberglass wool boards 5 arranged around the vacuum insulation board, facilitating assembly and improving construction efficiency. The basic unit is 300mm × 600mm, the vacuum insulation board is 240mm × 540mm, and the perimeter 30mm × 30mm uses high-strength fiberglass wool boards 5. The unit board size can be adjusted according to the dimensions of the building site. That is, the thermal insulation and fireproof layer is composed of several basic insulation core material units; the main body insulation core material uses VIP vacuum insulation board 3, and the edge insulation core material uses high-strength fiberglass wool boards 5. Figures 3-5 As shown, the dimensions of the basic unit can be adjusted according to the dimensions of the building site. Figure 3 The dimensions are 800mm*3360mm. Figure 4 The medium size is 730mm*3360mm. Figure 5 The dimensions are 940mm*3360mm.
[0054] The preparation steps of the above-mentioned inorganic composite internal insulation board are as follows:
[0055] Step 1: Select finish 4 based on architectural requirements. The standard size is 600mm × 1200mm. Lay it flat.
[0056] Step 2: Spray adhesive all over the surface and firmly bond the four 240mm×540mm vacuum insulation boards to the surface 4 in sequence. At the same time, use high-strength fiberglass cotton boards 5 of the same thickness and size of 30mm×30mm to fix the edge strip.
[0057] Step 3: Spray adhesive all over the surface, overlap the aerogel cotton felt 2 with the thermal insulation and fireproof layer in a staggered manner, and stick and fix it to reduce the impact of gaps on the thermal insulation effect of the wall panel.
[0058] Step 4: Attach and fix the non-woven fabric 1 to the aerogel cotton felt 2, and wrap the aerogel cotton felt 2 to prevent it from shedding powder.
[0059] For irregularly shaped walls, the layout can be determined based on the site dimensions, and the same steps as described above can be followed for preparation.
[0060] The inorganic composite internal insulation board provided in this embodiment has a core material composed of VIP vacuum insulation board and aerogel high-efficiency insulation material, consisting of several basic units. From the wall to the interior, the core material consists of non-woven fabric 1, aerogel cotton felt 2, VIP vacuum insulation board 3, and a finishing 4. The main body insulation core material uses VIP vacuum insulation board 3, while the edge insulation core material uses high-strength fiberglass cotton board 5 of the same thickness. The wall panel has a Class A non-combustible fire rating and an equivalent thermal conductivity ≤0.025W / m. 2 •K offers excellent energy-saving performance. It can be used as an industrialized wall panel, featuring a simple and rational structure. During construction, it utilizes adhesive anchoring or a keel system, such as… Figure 6 As shown, an adhesive-anchor system is used. A leveling layer 7 is constructed on the inner side of the base wall 6, and an adhesive layer 8 is constructed on the outer side of the leveling layer 7. The non-woven fabric 1 of the inorganic composite internal insulation board is adhered to the adhesive layer 8, and anchored to the base wall 6 by anchor bolts 9 passing through the fiberglass wool board 5 between the two vacuum insulation boards 3, thus achieving the construction of the inorganic composite internal insulation board. Figure 7 As shown, a keel system is adopted. The keel 10 is fixed to the inside of the base wall 6 using anchor bolts 9. The connecting part of the hanger passes through the fiberglass wool board 5 between two vacuum insulation boards 3. The screws of the hanger fix the connecting part to the keel 10, thereby dry-hanging the inorganic composite internal insulation board onto the keel 10, realizing the construction of the inorganic composite internal insulation board. The inorganic composite internal insulation board provided in this embodiment is safe and reliable, and can meet the requirements of nailing, cutting, standardization, and modularization in engineering applications. If there are special requirements for sockets or decoration in the project, customized production can be carried out because the high-strength fiberglass wool board 5 that can be cut is used in the local layout design. Furthermore, it can be widely used in energy-saving buildings and ultra-low energy consumption buildings in hot-summer and cold-winter regions, hot-summer and warm-winter regions, and temperate regions. The industrialized wall panel construction is simple and efficient.
[0061] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
