Description

Technical Field

[0001] The utility model belongs to the technical field of thermal insulation boards, and in particular relates to a waterproof, fire-resistant and environment-friendly building perimeter thermal insulation board. Background Art

[0002] In the current market, insulation boards primarily use two core materials: pure rock wool and pure polyurethane. However, pure polyurethane is not fireproof (it burns rapidly when exposed to open flames and extinguishes itself when removed from flames), and pure rock wool is not waterproof. There is a growing market demand for insulation boards that are both waterproof and fireproof. To address the waterproofing issues of insulation boards with pure rock wool as the core material, some companies use hydrophobic rock wool instead of non-hydrophobic rock wool. However, over time, hydrophobic rock wool oxidizes, resulting in the same water absorption rate as non-hydrophobic rock wool. Other companies use aluminum self-adhesive tape to seal the ends of the insulation boards to prevent moisture absorption by the exposed rock wool. However, the aluminum self-adhesive tape is susceptible to rot and can easily fall off the insulation board if exposed to moisture or rain for extended periods. In addition, rock wool is made of basalt as the main raw material, which is a fiber material. During the construction process, these fibers are easily inhaled into the human respiratory tract and lungs, and cannot be degraded and discharged. Eventually, they penetrate into the human respiratory tract and lungs, posing a threat to human health! Utility Model Content

[0003] In order to solve the problems of poor waterproofness and threat to human health of existing insulation boards, the purpose of the utility model is to provide a waterproof, fire-resistant and environmentally friendly building exterior insulation board.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0005] A waterproof, fire-resistant and environmentally friendly building exterior insulation board, comprising an upper panel, a lower panel and a core material located therebetween, the special feature of which is that the core material comprises an upper core material and a lower core material, the upper core material is polyurethane and is grooved, and the lower core material is an inorganic insulation material; the notch of the upper core material faces downward and the central axis of the notch is parallel to the length direction of the insulation board, the top surface is connected to the upper panel, and the bottom surface is connected to the lower panel; the lower core material is located in the notch of the upper core material, and the outer periphery of the lower core material is tightly fitted with the inner wall of the notch of the upper core material, and the bottom surface of the lower core material is flush with the bottom surface of the upper core material; the two ends of the insulation board perpendicular to the length direction of the insulation board are provided with edge sealing at the position corresponding to the lower core material, and the outer surface of the edge sealing is flush with the outer surface of the upper core material at the end, and the edge sealing is polyurethane or extruded board.

[0006] Preferably, the inorganic thermal insulation material is rock wool or magnesium oxysulfate.

[0007] Preferably, matching mortise and tenon structures are provided on both sides of the insulation board parallel to the length direction of the insulation board, and the mortise and tenon structures are formed by bending the upper panel and / or the lower panel toward the upper core material on the same side.

[0008] Preferably, the mortise and tenon structure is a C-type, E-type or H-type commonly used in the art. These shapes are conventional in the art.

[0009] Preferably, insulation nails are sometimes required to be installed during installation to enhance the fixing effect of the insulation board; when installing insulation nails, holes need to be drilled. In order to ensure the waterproof effect at the drilled holes, it is preferred that a waterproof block is embedded on the lower core material of the insulation board at a position corresponding to the pre-designed insulation nail installation position. The size of the waterproof block is slightly larger than the insulation nail (ensuring that after drilling a hole in the waterproof block, the hole is at a certain distance from the edge of the waterproof block after accommodating the insulation nail. The distance is preferably 100~200mm. For example, a circular hole with a diameter of 500mm needs to be drilled, and the corresponding waterproof block is a cylinder with a diameter of 700mm). The waterproof block and the lower core material around it are composited into one (when the waterproof block is an extruded board, the waterproof block and the lower core material are bonded together with a high-temperature resistant adhesive; when the waterproof block is polyurethane, it is bonded and compounded with a high-temperature resistant adhesive or holes are drilled in advance, and the polyurethane precursor foaming liquid is poured in situ, and then the waterproof block and the lower core material are composited together through in-situ polymerization and foaming). The waterproof block is polyurethane or extruded board. This design ensures that when drilling holes (drilling from the upper panel towards the lower panel), after the waterproof block located at the lower core material is drilled, the inorganic insulation material around the hole is still sealed by polyurethane or extruded board. These two materials have excellent waterproof effects, avoiding affecting the insulation effect of the lower core material due to drilling.

[0010] Preferably, the upper panel and the lower panel are both color-coated steel plates, which can be flat plates or corrugated plates commonly used in the art.

[0011] Preferably, the upper core material and the lower core material, the upper core material and the upper panel, the upper core material and the lower panel, and the lower core material and the lower panel are bonded together with a high-temperature resistant adhesive; when the edge sealing is an extruded board, the lower core material and the edge sealing are bonded together with a high-temperature resistant adhesive; when the edge sealing is polyurethane, the lower core material and the edge sealing are bonded together with a high-temperature resistant adhesive, or the edge sealing and the lower core material are bonded together by in-situ pouring of a polyurethane precursor foaming liquid and then in-situ polymerization and foaming.

[0012] The advantages of this utility model are as follows:

[0013] 1. In the present invention, the upper core material is groove-shaped, and the lower core material is located in the groove of the upper core material. At the same time, the two ends of the insulation board perpendicular to the length direction of the insulation board are also provided with edge sealing at the position corresponding to the lower core material. Therefore, the inorganic insulation material of the lower core material is completely wrapped and sealed by the edge sealing and the groove of the upper core material. The two materials of polyurethane and extruded board have excellent waterproof effects, which can achieve waterproof and moisture-proof, avoid the inorganic insulation material from getting damp and absorbing water during use and transportation, and broaden the application field of the product; at the same time, because the inorganic insulation material is completely sealed and wrapped, the rock wool fiber / glass fiber in magnesium oxysulfate is not easily exposed, will not cause harm to the human body and the environment, and is environmentally friendly; the present invention not only overcomes the fire resistance problem of the insulation board with pure polyurethane as the core material, but also overcomes the non-waterproof problem of the insulation board with rock wool as the core material, and has the advantages of being waterproof, fire-resistant and environmentally friendly;

[0014] 2. The utility model has a long fire resistance time (it can still maintain its integrity without collapse after burning for 1 hour), which buys time to save lives and property safety. It is completely possible to evacuate people and rescue other materials during this period;

[0015] 3. The upper core material of the utility model is a polyurethane board, and the lower core material is an inorganic thermal insulation material. Since the mechanical strength of polyurethane is higher than that of inorganic thermal insulation materials, the overall strength of the utility model is higher than that of traditional thermal insulation boards.

[0025] Example 2

[0026] The difference from Example 1 is that: the inorganic thermal insulation material is magnesium oxysulfate; the edge sealing 3 is an extruded board; and the rest is the same as Example 1.

[0027] Example 3

[0028] like Figure 4As shown, the difference from Example 1 is that a waterproof block 4 is embedded in the lower core material 22, and the waterproof block 4 is polyurethane; the rest is the same as Example 1.

[0029] Comparative Example 1

[0030] Traditional insulation panels (pure rock wool) consist of an upper panel, a lower panel, and a core material located between them. The core material is made of pure rock wool. C-shaped mortise and tenon joints are installed on both sides of the insulation panel, parallel to its length. These joints are formed by bending the upper and lower panels toward the core material on the same side. The core material is bonded to the upper panel and the lower panel with a high-temperature-resistant adhesive. The upper and lower panels are flat, color-coated steel sheets.

[0031] Comparative Example 2

[0032] Traditional insulation panels (pure polyurethane) consist of an upper panel, a lower panel, and a core material located between them. The core material is made of pure polyurethane. C-shaped mortise and tenon joints are installed on both sides of the insulation panel, parallel to its length. These joints are formed by bending the upper and lower panels toward the core material on the same side. The core material is bonded to the upper panel and the lower panel with a high-temperature-resistant adhesive. The upper and lower panels are flat, color-coated steel sheets.

[0033] Comparative Example 3

[0034] Traditional insulation panels (pure extruded panels) consist of two panels, upper and lower, with a core material located between them. The core material is pure extruded board. C-shaped mortise and tenon joints are installed on both sides of the insulation panel, parallel to its length. These joints are formed by bending the upper and lower panels toward the core material on the same side. The core material and upper and lower panels are bonded together with a high-temperature-resistant adhesive. The upper and lower panels are flat, color-coated steel sheets.

[0035] Fire tests: Since fires typically occur inside buildings, the insulation board of Example 1 was ignited with an ignition torch on one side of the lower panel 12. Since the insulation boards of Comparative Examples 1-3, whose core materials are pure rock wool, pure polyurethane, or pure extruded board, could be ignited with an ignition torch on either side of the upper or lower panel. The results showed that after one hour of burning, the insulation board of Example 1 and the conventional insulation board (pure rock wool) of Comparative Example 1 remained intact and did not collapse. However, the conventional insulation board (pure polyurethane) of Comparative Example 2 and the conventional insulation board (pure extruded board) of Comparative Example 3 collapsed after only 10 minutes of burning. This fully demonstrates that the insulation board of the present invention has excellent fire resistance.

[0036] Waterproofing tests: The waterproof, fire-resistant, and environmentally friendly building exterior insulation board of Example 1, the traditional insulation board (pure rock wool) of Control Example 1, the traditional insulation board (pure polyurethane) of Control Example 2, and the traditional insulation board (pure extruded board) of Control Example 3 were completely immersed in water. The results showed that after 24 hours of immersion, the water permeability of the insulation board of Example 1, Control Example 2 (pure polyurethane), and Control Example 3 (pure extruded board) was between 3% and 4% by weight. However, the water permeability of the traditional insulation board (pure rock wool) of Control Example 1 reached 20% by weight after only 2 hours of immersion. This fully demonstrates that the insulation board of the present invention has excellent waterproof properties.
