Description

Technical Field

[0001] This utility model belongs to the technical field of building insulation materials, specifically involving a vacuum insulation board made of multiple composite materials. Background Technology

[0002] Vacuum insulation panels are widely used in building insulation due to their extremely low thermal conductivity. However, current vacuum insulation panels typically employ a single protective panel composite structure, which suffers from insufficient fire resistance, low compressive strength, and poor weather resistance. Furthermore, the central support strips in the vacuum insulation panel provide poor bending resistance. Therefore, there is a need to develop a composite vacuum insulation panel that integrates multiple properties such as fire resistance, compressive strength, and weather resistance. Utility Model Content

[0003] Therefore, it is necessary to provide vacuum insulation panels with multiple composite materials to address the existing technical problems.

[0004] To solve the problems of the existing technology, the technical solution adopted by this utility model is as follows:

[0005] A multi-composite vacuum insulation panel includes several vacuum insulation panels, with support strips between adjacent panels. Protective strips are provided at the outer edges of the vacuum insulation panels. The outer side of each panel is sequentially laminated with a first fireproof layer, a compressive strength layer, and an outer protective composite layer; the inner side is sequentially laminated with a second fireproof layer, a weather-resistant layer, and an inner protective composite layer. The top and bottom of the outer side of the protective strips are provided with protective flanges that enclose the outer and inner protective composite layers. The support strips have hollow cavities containing V-shaped metal reinforcing ribs. Mounting holes are provided on the support strips, and support sleeves are fixed within these holes. The upper and lower ends of the support sleeves are flush with the outer sides of the outer and inner protective composite layers, respectively. Limiting connectors are provided inside the support sleeves, with wire mesh connected to both ends of the limiting connectors.

[0006] As a preferred option, the outer protective composite layer consists of basalt fiberboard and graphite extruded board from the inside out, bonded together with a high-temperature resistant adhesive; the inner protective composite layer consists of glass fiber reinforced plastic board and flame-retardant polyurethane board from the outside in, bonded together with an elastic sealant. The basalt fiberboard offers excellent fire resistance, while the graphite extruded board provides thermal insulation; the combination of these two enhances the overall performance of the outer protective system. The glass fiber reinforced plastic board exhibits strong weather resistance, and the flame-retardant polyurethane board enhances thermal insulation, meeting the requirements of outdoor environments.

[0007] As a preferred embodiment, the first and second fireproof layers are intumescent fire-retardant coatings that expand to form a fire barrier when exposed to fire; the compressive strength reinforcing layer is a honeycomb aluminum foil core material, utilizing the honeycomb structure to disperse stress and improve overall compressive strength; and the weather-resistant layer is a fluorocarbon resin coating. These features enhance the board's resistance to natural elements such as ultraviolet radiation and rain.

[0008] As a preferred option, the support strip is a composite structure consisting of modified phenolic foam wrapped around a PVC frame, and the inner connecting surface of the protective flange is coated with a polysulfide sealant layer to enhance waterproofing.

[0009] As a preferred embodiment, the outer sides of the opposite protective strips are respectively provided with arc-shaped snap-fit ​​protrusions and snap-fit ​​grooves to facilitate the positioning and connection of adjacent plates. The inner side of the protective strip is provided with a sealing groove, and a sealing strip is provided in the sealing groove to enhance the waterproof capability.

[0010] As a preferred embodiment, the limiting connector includes a stepped connecting rod sleeved within a support sleeve. Both ends of the connecting rod are threaded to a suspension tray. A U-shaped limiting plate is fixed to the outside of the suspension tray. A bending plate, fitted onto the connecting rod, is located on the outside of the suspension tray. Both ends of the bending plate have bent flanges, and a clamping cap threaded onto the connecting rod is located on the outside of the bending plate. Through the cooperation of the bending plate and the suspension tray, the wire mesh can be securely suspended, and the suspension position can be adjusted.

[0011] As a preferred embodiment, a pressure plate is fitted on the connecting rod inside the suspension tray, and a limit plate is fixed inside the pressure plate to limit the connecting rod and prevent the wire mesh from moving.

[0012] As a preferred embodiment, the outer side of the pressure plate is provided with an adjusting sleeve that fits onto the connecting rod. The adjusting sleeve is equipped with a locking screw, which can adjust the position of the limiting plate according to the thickness of the composite material.

[0013] The advantages of this utility model compared with the prior art are:

[0014] Synergistic effect of multiple composite structures: The fire rating is improved to Class A by combining the first fireproof layer, the second fireproof layer, the outer protective composite layer and the inner protective composite layer; the compressive strength of the board is greatly enhanced by the compressive strength layer; the weather-resistant layer and the inner protective composite layer work together to greatly extend the weather resistance life.

[0015] Enhanced protective structure and support strength and stability: The support strip has both insulation and structural support functions. The internal hollow cavity reduces weight, while the metal reinforcing ribs improve bending resistance. The outer side of the protective strip has a protective flange that covers the first fireproof layer, the compressive strength enhancement layer, the outer protective composite layer, the second fireproof layer, the weather-resistant layer, and the inner protective composite layer, thereby increasing the protective effect.

[0023] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0024] Example 1, Reference Figures 1 to 5 The vacuum insulation board is made of multiple composite materials, including several vacuum insulation panels 5. Support strips 12 are provided between adjacent vacuum insulation panels 5. Protective strips 16 are provided at the outer edge of the vacuum insulation panels 5. The outer side of the vacuum insulation panels 5 is sequentially composited with a first fireproof layer 4, a compressive strengthening layer 3 and an outer protective composite layer. The inner side is sequentially composited with a second fireproof layer 6, a weather-resistant layer 7 and an inner protective composite layer. The top and bottom of the outer side of the protective strip 16 are provided with protective flanges 21 that enclose the outer and inner protective composite layers. The support strip 12 has a hollow cavity inside, and V-shaped metal reinforcing ribs 13 are provided inside the hollow cavity. The support strip 12 has mounting holes, and a support sleeve 11 is fixed in the mounting holes. The upper and lower ends of the support sleeve 11 are flush with the outer sides of the outer and inner protective composite layers, respectively. The support sleeve 11 has a limiting connector, and steel wire mesh 8 is connected to both ends of the limiting connector.

[0025] The core structure of this multi-composite vacuum insulation panel is the vacuum insulation panel 5, which is 10-20mm thick. As the core insulation layer, this thickness ensures an extremely low thermal conductivity (≤0.003W / (m·K)) while balancing the overall weight and insulation efficiency. The first fireproof layer 4 and the second fireproof layer 6 are both intumescent fire-retardant coatings, 0.5-1mm thick. This thickness ensures rapid expansion upon exposure to fire, forming a dense fire barrier with an expansion ratio ≥250%, without excessively increasing the panel thickness. The compressive strength reinforcement layer 3 is 3-5mm thick, meeting the pressure bearing requirements of cast-in-place concrete. The weather-resistant layer 7 is 0.3-0.8mm thick. This thickness forms a continuous, dense protective film, effectively resisting UV aging and rain erosion, making it suitable for long-term outdoor use.

[0026] During construction, the installation method is selected according to the wall type: load-bearing walls adopt a single-sided wire mesh structure 8, with a 50mm concrete protective layer poured on the outside, which is not shown in the figure; infill walls adopt a double-sided wire mesh structure 8, with a 60mm concrete protective layer 24 poured on each side, and the length of the limiting connector is adjusted to meet different pouring thickness requirements.

[0027] In Example 2, based on Example 1, the outer protective composite layer consists of basalt fiberboard 2 and graphite extruded polystyrene board 1 from the inside out, bonded together with a high-temperature resistant adhesive. The inner protective composite layer consists of glass fiber reinforced plastic board 10 and flame-retardant polyurethane board 9 from the outside in, bonded together with an elastic sealant. The basalt fiberboard 2 is 5-8mm thick, utilizing its high-temperature resistance and high strength to provide fireproof support for the vacuum core layer. The graphite extruded polystyrene board 1 is 10-15mm thick, serving as an auxiliary insulation layer, resulting in a total composite thickness of 15-23mm. The glass fiber reinforced plastic board 10 is 3-5mm thick, protecting the inner structure from external mechanical damage due to its excellent weather resistance and impact resistance. The flame-retardant polyurethane board 9 is 8-12mm thick, combining insulation and flame-retardant functions, resulting in a total composite thickness of 11-17mm.

[0028] The first fireproof layer 4 and the second fireproof layer 6 are intumescent fireproof coating layers, the compressive strength reinforcement layer 3 is a honeycomb aluminum foil core material, and the weather-resistant layer 7 is a fluorocarbon resin coating.

[0029] The support strip 12 is a composite structure consisting of modified phenolic foam wrapped around a PVC frame, and the inner connecting surface of the protective flange 21 is coated with a polysulfide sealant layer 22. The surface of the wire mesh 8 can be sprayed with an epoxy resin anti-corrosion layer to extend its service life.

[0030] The protective strip 16 has an arc-shaped snap-fit ​​protrusion 18 and a snap-fit ​​groove on its outer middle side, and a sealing groove on its inner side, within which a sealing strip 23 is installed. The polysulfide sealant layer 22, in conjunction with the sealing strip 23, enhances its waterproof performance. The sealing strip 23 is made of butyl rubber.

[0031] The limiting connector includes a stepped connecting rod 14 sleeved in the support sleeve 11. Both ends of the connecting rod 14 are threaded to a suspension tray 25. A U-shaped limiting plate is fixed on the outside of the suspension tray 25. A bending plate 15 is provided on the outside of the suspension tray 25 and sleeved on the connecting rod 14. Both ends of the bending plate 15 are provided with bent flanges. A clamping cap is threaded on the connecting rod 14 on the outside of the bending plate 15.

[0032] A pressure plate 17 is fitted on the connecting rod 14 inside the suspension tray 25, and a limit plate 19 is fixed inside the pressure plate 17.

[0033] An adjusting sleeve 20 is provided on the outer side of the pressure plate 17 and is fitted onto the connecting rod 14. The adjusting sleeve 20 is equipped with a locking screw. When suspending the wire mesh 8, the connecting rod 14 is inserted into the support sleeve 11, and then the adjusting sleeve 20 is fitted on. The position of the adjusting sleeve 20 is adjusted so that the limiting plate 19 is attached to the outer side of the composite board. Then the locking screw is tightened. Then the suspension tray 25 is screwed onto the outer end of the connecting rod 14. The wire mesh 8 is hung on the limiting plate on the outer side of the suspension tray 25. Then the bending plate 15 is fitted on and bent inward so that the bent edge covers the outer side of the limiting plate. Then the pressure cap is screwed on.
