Description

Technical Field

[0001] This utility model relates to the field of insulation board technology, specifically a high-performance Class A non-combustible insulation board. Background Technology

[0002] Currently, insulation boards that meet the energy-saving requirements of ultra-low energy consumption buildings generally require an application thickness of 240-300mm. On the one hand, thicker insulation layers bring great inconvenience to construction. On the other hand, insulation boards such as rock wool boards are currently commonly used Class A non-combustible insulation materials for building exterior walls, but their strength is low, only 10KPa, and the system's wind pressure resistance safety factor is 3.3, which is far lower than other types of insulation materials. In addition, with the increase in application thickness, the system structure has evolved from a veneer structure to a cantilever beam structure, increasing the risk of detachment.

[0003] Vacuum insulation panels are an industry-recognized material with high thermal insulation performance. However, they have problems such as low bonding strength and large gaps between panels, which make process control difficult. In addition, they are prone to air leakage, and the consequences of leakage can be disastrous, which makes the industry hesitant to use them.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a high-performance Class A non-combustible insulation board in order to achieve a more practical value. Utility Model Content

[0005] The purpose of this invention is to provide a high-performance Class A non-combustible insulation board to solve the problems mentioned in the background art.

[0006] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0007] A high-performance Class A non-combustible insulation board includes an insulation board body. The insulation board body includes a bottom panel. A first side strip, a second side strip, a third side strip, and a fourth side strip are respectively connected around the upper surface of the bottom panel. A square groove is formed between the inner walls of the first side strip, the second side strip, the third side strip, and the fourth side strip. A vacuum insulation board is provided inside the square groove. A top panel is connected to the upper end of the vacuum insulation board. The top panel, the bottom panel, the first side strip, the second side strip, the third side strip, and the fourth side strip are all made of polymerized polystyrene board. The vacuum insulation board includes a core material. A high-performance thermal bridging barrier film layer is provided on the outside of the core material.

[0008] Furthermore, an adhesive layer is provided on the upper surface of the bottom panel, the bottom end of the adhesive layer is bonded to the upper end of the bottom panel, and the four sides of the upper end of the adhesive layer are bonded to the first side strip, the second side strip, the third side strip and the fourth side strip respectively.

[0009] The beneficial effects of adopting the above further solution are as follows. By providing an adhesive layer, it is convenient to sequentially bond the first side strip, the second side strip, the third side strip, and the fourth side strip to the bottom panel, thereby facilitating the formation of a firm integral body among the first side strip, the second side strip, the third side strip, the fourth side strip, and the bottom panel. At the same time, the gaps between the side strips and the panel, and between the side strips and the core material are filled, preventing the flow of air in the microspace and preventing the impact on the overall heat insulation performance.

[0010] Further, the adhesive layer is in a "hui" character shape, and the thickness of the adhesive layer is less than 1 mm. There are strict requirements for the operable time of the adhesive of the bonding layer. It must meet the requirements of bonding performance and filling performance of the foaming ratio, and also meet the operable time requirement without affecting the production efficiency.

[0011] The beneficial effects of adopting the above further solution are as follows. By setting the adhesive layer in a "hui" character shape, it is convenient to bond the first side strip, the second side strip, the third side strip, and the fourth side strip with less adhesive.

[0012] Further, a first connecting layer is provided on the inner wall of the square groove, and a second connecting layer is provided at the bottom end of the top panel. The inner wall of the first connecting layer is adhesively bonded to the outer wall of the vacuum insulation panel, and the bottom end of the second connecting layer is adhesively bonded to the upper end surface of the vacuum insulation panel.

[0013] The beneficial effects of adopting the above further solution are as follows. By providing the first connecting layer and the second connecting layer, it is convenient to fix the vacuum insulation panel in the square groove formed between the top panel and the inner walls of the first side strip, the second side strip, the third side strip, the fourth side strip, and the bottom panel, preventing the vacuum insulation panel from falling off.

[0014] Further, both the first connecting layer and the second connecting layer are made of two-component polyurethane glue, and the thicknesses of both the first connecting layer and the second connecting layer are less than 1 mm.

[0015] The beneficial effects of adopting the above further solution are as follows. By making the first connecting layer and the second connecting layer of two-component polyurethane material and the thicknesses of the first connecting layer and the second connecting layer less than 1 mm, they can be firmly bonded to the smooth surface of the vacuum insulation panel. At the same time, when the vacuum insulation panel is subjected to the extrusion and collision such as wind pressure, transportation, and construction, and the temperature stress of thermal expansion and contraction, it serves as a buffer layer for the vacuum insulation panel to prevent the vacuum insulation panel from being damaged and leaking air.

[0016] Further, one ends of both the first side strip and the second side strip extend to the outside of the bottom panel, and connecting grooves are provided at the positions of the third side strip and the fourth side strip between the top panel and the bottom panel.

[0017] The beneficial effect of adopting the above-mentioned further solution is that, by extending one end of the first and second side strips to the outside of the bottom panel, when a pair of insulation board bodies need to be connected laterally, the first side strip on the other insulation board body is inserted into the connecting groove of the insulation board body near the third side strip, so that the pair of insulation board bodies are assembled laterally; when a pair of insulation board bodies need to be connected vertically, the second side strip on the other insulation board body is inserted into the connecting groove of the insulation board body near the fourth side strip, so that the pair of insulation board bodies are assembled vertically.

[0018] Furthermore, a first through hole and a pair of second through holes are respectively opened on the first side strip and the second side strip, and a pair of third through holes and a pair of fourth through holes are respectively opened on the top panel and the bottom panel near the connecting groove. The diameters of the first through hole and the third through hole are the same, and the diameters of the second through hole and the fourth through hole are the same.

[0019] The beneficial effect of adopting the above-mentioned further solution is that, after a pair of insulation board bodies are assembled horizontally, the first through hole and the third through hole are aligned so that the anchor bolts can be inserted into the corresponding first through hole and the third through hole to fix the pair of insulation board bodies; after a pair of insulation board bodies are assembled vertically, the second through hole and the fourth through hole are aligned so that the anchor bolts can be inserted into the corresponding second through hole and the fourth through hole to fix the pair of insulation board bodies.

[0020] Furthermore, the barrier film layer is provided with a surface layer, a gas barrier layer, a heat-sealing layer, a flame-retardant layer and a reinforcing layer from the outside to the inside. The surface layer is made of polyethylene, the gas barrier layer is made of composite gas barrier film material, and the reinforcing layer is made of biaxially oriented polyester film material.

[0021] The beneficial effects of adopting the above-mentioned further solutions are that by setting a barrier film layer to cover and protect the core material and to break thermal bridges, by setting a surface layer to effectively prevent heat from being transferred through radiation and convection, thereby significantly reducing heat conduction efficiency, by setting a gas barrier layer to prevent gas penetration and moisture entry, ensuring the stability of vacuum, and by setting a reinforcing layer, which is made of biaxially oriented polyester film, the overall strength of the vacuum insulation board is improved.

[0022] Compared with existing technologies, the beneficial effects of this utility model are as follows: This high-performance Class A non-combustible insulation board, by setting a first, second, third, and fourth side strip on the upper perimeter of the bottom panel, forms a square groove between the inner walls of the first, second, third, and fourth side strips, thereby bonding the vacuum insulation board inside the square groove. This fully utilizes its high-efficiency insulation advantage while eliminating the risk of air leakage that may occur during transportation, loading and unloading, construction, and natural impacts. Even if air leakage does occur, it can be prevented by strong wrapping. The coating effectively restricts its expansion and deformation. By using polymerized polystyrene board for the top panel, bottom panel, first side strip, second side strip, third side strip, and fourth side strip, the polymerized polystyrene board is made by uniformly penetrating inorganic cementitious slurry containing closed-cell nanomaterials into a specially made EPS substrate through a special process. After a series of chemical reactions, it forms a stable inorganic nanocrystalline body with a negative calorific value, achieving an A2 fire resistance rating. It has a higher fire resistance rating and stable performance, with a high safety factor, and is mainly used as an exterior wall fireproofing and thermal insulation energy-saving material.

The apertures are consistent; the second through hole 1011 and the fourth through hole 1013 have the same aperture. The barrier film layer 2002 is provided with a surface layer 2003, a gas barrier layer 2004, a heat-sealing layer 2005, a flame-retardant layer 2006, and a reinforcing layer 2007 sequentially from the outside to the inside. The surface layer 2003 is made of polyethylene, the gas barrier layer 2004 is made of composite gas barrier film, and the reinforcing layer 2007 is made of biaxially oriented polyester film. The first side strip 1002 and one end of the second side strip 1003 extend to the outside of the bottom panel 1001. When a pair of insulation board bodies 100 need to be connected laterally, the first side strip 1002 on the other insulation board body 100 is inserted into a... The insulation board body 100 is connected to the groove 300 near the third side strip 1004, allowing the pair of insulation board bodies 100 to be assembled horizontally. When the pair of insulation board bodies 100 need to be connected vertically, the second side strip 1003 on the other insulation board body 100 is inserted into the groove 300 near the fourth side strip 1005 of one insulation board body 100, allowing the pair of insulation board bodies 100 to be assembled vertically.
