[0007] Currently, polystyrene particle insulation boards are commonly used as building insulation materials. While they offer good flexibility and crack resistance, they are also weak and susceptible to deformation due to external forces. The thermal conductivity of polystyrene particle insulation boards is generally between 0.058 and 0.062 W / (m·K). However, with the increasing demands for building insulation, using only polystyrene particle insulation boards within a specific thickness range does not meet current building insulation requirements.

[0008] Therefore, in view of this, the existing structure and defects are studied and improved, and a thermal insulation material board is provided to achieve the purpose of having more practical value. Utility Model Content

[0009] In order to solve the above technical problems, the utility model provides a thermal insulation material board to solve the problem that under the current building thermal insulation standards, only polystyrene particle thermal insulation board cannot meet the building thermal insulation needs.

[0010] The purpose and effect of the thermal insulation material board of the utility model are achieved by the following specific technical means:

[0011] A thermal insulation material board, comprising:

[0012] A polystyrene particle insulation board, an aerogel felt layer and an inner bonding layer. The aerogel felt layer is provided with two layers. The polystyrene particle insulation board is provided between the two aerogel felt layers. An inner bonding layer is provided between the aerogel felt layer and the polystyrene particle insulation board.

[0013] Furthermore, the aerogel felt layer is provided with a plurality of through holes, each of the through holes is provided with a riveted portion, one end of the riveted portion is fixedly connected to the inner adhesive layer, and the other end of the riveted portion is provided with a pier head, which is provided on the outer surface of the aerogel felt layer.

[0014] Furthermore, the thickness of the aerogel felt layer is 2 mm to 20 mm, the thickness of the polystyrene particle insulation board is 20 mm to 50 mm, and the sum of the areas of all through holes accounts for 20% to 30% of the surface area of ​​the aerogel felt layer.

[0015] Furthermore, the riveted portion and the inner bonding layer are mortar.

[0016] Furthermore, the polystyrene particle insulation board, two layers of aerogel felt and two inner adhesive layers form an inner insulation structure, the inner insulation structure is covered with a coating net and an outer coating layer, and the coating net is arranged in the outer coating layer.

[0017] Furthermore, the coating mesh is a steel wire mesh, and the inner bonding layer and the outer coating layer are mortar.

[0018] Furthermore, an outer adhesive layer is provided on the outer surface of the inner adhesive layer, and a mesh layer is provided inside the outer adhesive layer.

[0019] Furthermore, the inner bonding layer and the outer bonding layer are mortar.

[0020] Furthermore, the mesh layer is an alkali-resistant glass fiber mesh.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] The present invention provides aerogel felt layers on both sides of a polystyrene particle insulation board, and bonds and secures the polystyrene particle insulation board and the aerogel felt layers via an inner bonding layer. Because the aerogel felt layers have a lower thermal conductivity than the polystyrene particle insulation board, the thermal insulation performance of the overall material is improved. Since the aerogel felt layers are disposed on both surface layers of the polystyrene particle insulation board, the thermal insulation performance of the material is significantly improved compared to a material using only the polystyrene particle board. Separately arranging the aerogel felt on both sides of the polystyrene particle board increases the thermal insulation margin of the material. When the aerogel felt on one side is punctured, the other side can reduce the impact of the thermal bridge at the puncture on the thermal insulation performance of the thermal insulation material. The inner bonding layer connects the polystyrene particle insulation board and the aerogel felt layer into a whole, making the overall thermal insulation material more stable and secure.

[0032] Example 1:

[0033] As attached Figure 1 To the attached Figure 4 As shown:

[0034] The utility model provides a thermal insulation material board, comprising:

[0035] The polystyrene particle insulation board 1, aerogel felt layer 2, and inner bonding layer 3 are provided. The aerogel felt layer 2 is provided in two layers. The polystyrene particle insulation board 1 is arranged between the two aerogel felt layers 2. The inner bonding layer 3 is provided between the aerogel felt layer 2 and the polystyrene particle insulation board 1. The inner bonding layer 3 is made of mortar. In this embodiment, by providing aerogel felt layers 2 on both sides of the polystyrene particle insulation board 1 and bonding the polystyrene particle insulation board 1 and the aerogel felt layers 2 via the inner bonding layer 3, the thermal insulation performance of the entire material is improved because the aerogel felt layer 2 has a lower thermal conductivity than the polystyrene particle insulation board 1.

[0036] The thickness of the aerogel felt layer 2 is 2 mm, and the thickness of the polystyrene particle insulation board 1 is 20 mm.

[0037] In this embodiment, aerogel felt layers 2 are provided on both sides of the polystyrene particle insulation board 1, and the polystyrene particle insulation board 1 and the aerogel felt layers 2 are bonded and fixed by an inner bonding layer 3. Since the aerogel felt layers 2 have a lower thermal conductivity than the polystyrene particle insulation board 1, the thermal insulation performance of the entire material is improved. Since the aerogel felt layers 2 are respectively provided on the two surface layers of the polystyrene particle insulation board 1, the thermal insulation performance of the material is significantly improved compared to that of the material using only the polystyrene particle board. At the same time, the aerogel felt is separately provided on both sides of the polystyrene particle board, which can increase the thermal insulation margin of the material. When the aerogel felt on one side is punctured, the other side can reduce the impact of the thermal bridge at the puncture point on the thermal insulation performance of the thermal insulation material. The inner bonding layer 3 serves to connect the polystyrene particle insulation board 1 and the aerogel felt layer 2 into a whole, making the thermal insulation material more stable and firm as a whole.

[0038] The aerogel felt layer is a flexible thermal insulation felt made of nano-silicon dioxide or metal aerogel as the main material and composited with glass fiber cotton or pre-oxidized fiber felt.

[0039] The inner bonding layer 3 specifically adopts an adhesive, which is a bonding material made of cement, sand, admixture and high-density polymer latex powder.

[0040] Example 2:

[0041] The remaining features are the same as those of Example 1, with the difference being that in this embodiment, a plurality of through holes 20 are provided on the aerogel felt layer 2, and the through holes 20 are provided with a riveted portion 21, one end of the riveted portion 21 is fixedly connected to the inner adhesive layer 3, and the other end of the riveted portion 21 is provided with a pier head 210, which is provided on the outer surface of the aerogel felt layer 2.

[0042] The riveted portion 21 and the inner bonding layer 3 are made of adhesive, and the thickness of the inner bonding layer 3 is 2 mm. The provision of the through hole 20 facilitates the extrusion of mortar from the through hole 20 during production, forming the riveted portion 21 with the pier head 210, making the connection between the aerogel felt layer 2 and the mortar more secure and improving the compressive strength.

[0043] The thickness of the aerogel felt layer 2 is 2 mm, and the thickness of the polystyrene particle insulation board 1 is 20 mm.

[0044] The total area of ​​all through holes 20 accounts for 20% of the surface area of ​​the aerogel felt layer 2. While ensuring a stronger connection between the aerogel felt layer 2 and the adhesive, as much surface area of ​​the aerogel felt layer 2 as possible is retained to find a more appropriate balance between thermal conductivity and connection strength.

[0045] Example 3:

[0046] The remaining features are the same as those of Example 1, with the difference being that in this embodiment, the polystyrene particle insulation board 1, two layers of aerogel felt 2, and two inner adhesive layers 3 form an inner insulation structure, which is then covered with a coating net 4 and an outer coating layer 5, with the coating net 4 disposed within the outer coating layer 5. This solution employs a fully enclosed fixing method, further strengthening the connection between the polystyrene particle insulation board 1, two layers of aerogel felt 2, and two inner adhesive layers 3. Furthermore, the coating net 4 and outer coating layer 5 form an encased shell, increasing the compressive strength and durability of the overall material. This allows for use as a non-disassembly formwork, capable of withstanding strong pressure during actual construction.

[0047] The covering mesh 4 is a 10-mesh steel mesh, and the inner bonding layer 3 is an adhesive.

[0048] The outer coating layer 5 is 10 mm thick, the aerogel felt layer 2 is 20 mm thick, and the polystyrene particle insulation board 1 is 100 mm thick. The steel mesh is added to the coating to improve the compressive strength of the material.

[0049] The outer covering layer 5 specifically adopts plastering mortar, which is made of cement, sand, admixture and high-density polymer latex powder and has certain deformation ability and impact resistance, and is wrapped with alkali-resistant glass fiber mesh cloth.

[0050] Example 4:

[0051] The remaining features are the same as those of Example 4, with the difference being that the mesh layer 7 in this embodiment is a 280g / m² alkali-resistant glass fiber mesh. This alkali-resistant glass fiber mesh effectively disperses stress in the finishing layer caused by factors such as temperature fluctuations and deformation of the base layer, preventing cracks in the mortar. It enhances the system's impact resistance and crack resistance, improving the durability of the insulation system and extending its service life. The alkali-resistant glass fiber mesh is a mesh-like glass fiber fabric made from a glassy raw material containing the alkali-resistant elements zirconium and titanium.

[0052] Embodiment 5:

[0053] The rest of the features are the same as those of the second embodiment, except that the total area of ​​all through holes 20 accounts for 30% of the surface area of ​​the aerogel felt layer 2 .

[0054] Compared with the second embodiment, the connection between the aerogel felt layer 2 and the adhesive is more firmly established. Since the area occupied by the through holes 20 is larger than that of the second embodiment, the thermal conductivity is higher.

[0055] The following table shows the thermal conductivity, compressive strength and combustion performance of the finished insulation materials of Examples 1 to 5 obtained through experiments.
