Description

Technical Field

[0001] [Cross - reference to Related Applications] This application claims the priority of a Chinese patent application with application number 202011463517.6 and filing date December 11, 2020, the content of which is incorporated herein by reference.

[0002] [Technical Field] This disclosure relates to the technical field of heat insulation and preservation, and specifically relates to a heat insulation and preservation composite panel and a manufacturing method thereof.

Background Art

[0003] Currently, there are various heat insulation and preservation panels in the market. Conventional heat insulation materials have a high density, poor heat insulation and preservation performance, a thick laying, a large material loss, high hygroscopicity, poor seismic resistance and environmental protection performance, and cannot meet the energy - saving standards. Furthermore, some heat insulation materials are harmful to the human body.

[0004] Aerogel is a porous material with a pore size on the nanometer order, its thermal conductivity is extremely low, and the heat insulation and preservation effect is high. In the prior art, by manufacturing a heat insulation and preservation composite panel with aerogel or an aerogel product as a sandwich structure, the impact resistance of aerogel is improved, and it is widely applied to the heat insulation of pipelines, building walls, vehicles, boxes / cabinets.

[0005] In the prior art, it is common that between an aerogel or an aerogel product as a heat insulation layer in a heat insulation and preservation composite panel and an external panel layer is adhered by a chemical method. However, due to the water - repellency of aerogel itself, it is difficult to ensure the strength of this adhesion, the overall tensile strength of the heat insulation and preservation composite board decreases, the hardness is low, the production process is complicated, and when a special adhesive is selected, it may lead to an increase in cost. Furthermore, since nano - aerogel felt is a glass fiber substrate, its hierarchical structure is loose, and it is easy to peel off and fall off after being pasted as a wall heat insulation layer, and there are safety problems. The above problems greatly limit the application and development of heat insulation and preservation composite boards made of aerogel.

Figure 1 is a perspective view of an embodiment of the heat-insulating and heat-preserving composite panel of the present disclosure, and Figure 2 is a schematic cross-sectional view of an embodiment of the heat-insulating and heat-preserving composite panel of the present disclosure.

[0021] The heat-insulating and heat-preserving composite panel has an inner outer layer 1, an intervening layer 2, a heat-insulating and heat-preserving layer 3, an intervening layer 2, an outer outer layer 4, and holes 5 from top to bottom. Of course, the heat-insulating and heat-preserving composite panel of the present disclosure may have only the inner outer layer 1 or the outer outer layer 4, or may have only one intervening layer 2, and the number of each layer is not limited. For example, the heat-insulating and heat-preserving layer 3 may be provided with two or more layers according to the actual situation. The thickness of each layer of the heat-insulating and heat-preserving composite panel is not limited. For example, each layer may have a thickness of 1 cm, or may have a thickness of 2 cm or more, and different thicknesses can be set according to the actual situation, which is not limited. However, considering the use as a wall heat-insulating layer, it is preferable that the thickness of the aerogel felt is 1 cm for each of the two layers.

[0022] In one or more embodiments, the heat-insulating and heat-preserving layer 3 includes, for example, aerogel felt, and may also include aerogel products such as aerogel cloth, aerogel paper, aerogel board, fiber-reinforced aerogel felt, and other aerogel shaped members, which is not limited.

[0025] In one or more embodiments, the intervening layer 2 may include, for example, one of the following: polyester fiber metal coated fabric, nonwoven fabric, glass fiber felt, or fiberglass mesh.

[0026] Of course, the materials for the interlayer 2 of the thermal insulation composite panel include: rigid paper, flexible paper, nonwoven fabric, offset paper, coated paper, glass card paper, laser paper, kraft paper, fluorescent paper, gold-plated paper, aluminum foil paper, fragile (anti-counterfeiting) paper, silver-plated paper, crepe paper, cloth label (Tyvek / nylon) paper, pearl paper, sandwich coated paper, variable information paper, low-density polyethylene, linear low-density polyethylene, high-density polyethylene, biaxially oriented polypropylene, cast polypropylene, polyphenylene sulfide, polystyrene, polyester, These materials are easily bonded to the outer layer by chemical means, including materials such as polyamide, polyvinylidene chloride, polycarbonate, polyvinyl alcohol, polylactic acid, aluminum foil, contact rubber, transparent polyester (PET), translucent polyester (PET), transparent directionally oriented polypropylene (OPP), translucent directionally oriented polypropylene (OPP), transparent vinyl chloride (PVC), bright white vinyl chloride (PVC), white matte polyvinyl chloride (PVC), synthetic paper, bright gold (silver) polyester, and gold (silver) matte polyester.

[0027] In one or more embodiments, the inner outer layer 1 and / or outer outer layer 4 may include, for example, one of the following: a metal plate, a ceramic plate, a stone plate, adhesive mortar, a cement board, a calcium silicate board, a gypsum board, a sound-absorbing material, or a sound-dampening material.

[0028] In one or more embodiments, the inner outer layer 1 and / or outer outer layer 4 may, for example, have one side made of a glossy composite core material, and the other side may be subjected to processes such as pile drawing and wire drawing after being coated with adhesive slime or the like, in order to facilitate attachment to walls or the like.

[0029] In one or more embodiments, the outer surface layer 4 is preferably made of a weather-resistant material such as metal or lightweight calcium silicate board. The outer surface layer 4 may be, for example, a cladding material and may be used in construction methods such as steel suspension work that adheres tightly to the wall.

[0030] In one or more embodiments, the inner outer layer 1 is preferably made of a material such as high-strength gypsum board or lightweight calcium silicate board, and it is preferable to apply processes such as pile drawing or wire drawing to improve adhesive strength and flatness when attached to a wall.

[0031] In one or more embodiments, the inner outer layer 1 and / or outer outer layer 4 may have holes 5 with a diameter of 2 to 50 mm drilled at intervals of 15 mm to 70 mm, or preferably holes 5 with a diameter of 5 to 20 mm drilled at intervals of 25 mm to 60 mm. As shown in Figure 1, for example, holes with a diameter of 15 mm may be drilled at intervals of 5 cm vertically and horizontally. When adhesive is applied to the inner outer layer 1 and / or outer outer layer 4 and attached to, for example, a wall, a better adhesive effect is achieved.

[0032] In one or more embodiments, the number, size, and layout of the holes 5 in the thermal insulation composite panel are not particularly limited, but the number, size, and layout of the holes 5 can be selected according to the requirements for adhesive effect. As shown in Figure 1, the holes 5 are circular, but are not limited to this, and the shape of the holes 5 may be other shapes, such as rectangles, squares, circles, slits, or other polygons.

[0033] In Figure 1, multiple holes 5 of the thermal insulation composite panel are shown arranged in a matrix at equal intervals. However, the arrangement is not limited to this; multiple holes 5 may be arranged in other pitches, layouts, or patterns, such as a concentric circular annular pattern or an irregular distribution pattern. Furthermore, the arrangement is not limited to multiple holes 5 being at equal intervals.

[0034] In Figure 1, a blind via is formed by removing a portion of the material from the inner outer layer 1 and / or the outer outer layer 4 to create the hole 5. However, the method is not limited to this; a through hole may also be formed by completely removing the material from the outer layer of hole 5.

[0035] Furthermore, the size and layout pattern of the holes 5 can be selected according to the required adhesive effect. Specifically, if a better adhesive effect is needed, the holes can be made larger or the number of holes can be increased, while conversely, the holes can be made smaller or the number of holes can be reduced.

[0036] In one or more embodiments, the inner outer layer 1 and / or the outer outer layer 4 may be provided with, for example, punches and / or slots, which are then joined integrally with other layers by physical means such as sutures or stapling. This allows for easy control of the position of the threads during sutures and / or stapling, resulting in a clean and aesthetically pleasing product form, preventing the threads and / or staples from protruding from the surface, and protecting the threads and / or staples from damage during use.

[0037] In one or more embodiments, the row pitch and / or column pitch of the slots is, for example, 30 mm to 60 mm, and the punch distance is, for example, 10 mm to 15 mm, preferably the row pitch and / or column pitch of the slots is 50 mm and the punch distance is 15 mm.

[0038] In one or more embodiments, the thermal insulation layer 3 is integrally joined to the intervening layer 2 by a physical means. Of course, the other layers, for example, the thermal insulation layer 3 and the inner outer layer 1 and / or outer outer layer 4, can also be joined by a physical means, but are not limited to this.

[0039] In one or more embodiments, the physical method may include at least one of the following: suture, staple fastening, riveting, bolting, engagement, or micro-hook attachment (e.g., hook-and-loop fasteners).

[0040] In one or more embodiments, when a physical method of suturing is used, for example, PTFE sewing thread (polytetrafluoroethylene sewing thread) that is acid- and alkali-resistant, corrosion-resistant, and high-temperature resistant is used for suturing. When a physical method of stapling is used, for example, a rod-shaped locking type metal aluminum alloy or high-strength carbon steel fitting is used for stapling.

[0041] PTFE sewing threads have a strong energy retention rate of around 80% after acid-alkali treatment. This is because PTFE has a unique molecular structure (PTFE molecules surround carbon chains with F atoms, and the CF bonds have large long and short bond energies), making it impossible to destroy the PTFE molecular structure with acids and alkalis. Because PTFE sewing threads have very high acid and alkali resistance, they can be used in most fume-filled environments.

[0042] Under temperature conditions of 230°C to 320°C, PTFE sewing thread exhibits de-orientation due to high temperatures, causing its strength and elongation at break to decrease and increase, respectively, with increasing heat treatment temperature. PTFE sewing thread can be used for extended periods within a temperature range of 230°C and is suitable for removing flue gas from waste incinerators and coal-fired boilers.

[0043] Of course, when using physical methods such as sutures or stapling, for example, acid- and alkali-resistant, corrosion-resistant, and high-temperature-resistant polymer nylon thread or other material wires may be used as suture lines or stapling lines, and are not particularly limited.

[0044] In one or more embodiments, the row pitch and / or column pitch of the suture line or stapled line is, for example, 30 mm to 60 mm, the stitch distance is, for example, 10 mm to 15 mm, and it is preferable that the row pitch and / or column pitch is 50 mm and the stitch distance is 15 mm.

[0045] In one or more embodiments, the intervening layer 2 can cover or enclose the thermal insulation layer 3, for example, when the thermal insulation layer 3 material enters manufacturing equipment such as a quilting sewing machine and is sewn, in order to prevent pollution of the workplace environment due to powder falling or glass fiber dust generation caused by the impact of the machinery, and to prevent lung damage to the human body.

[0046] In one or more embodiments, the inner outer layer 1 and / or the outer outer layer 4 are integrally bonded to the intervening layer 2 by a chemical method. The chemical method may include a method of bonding that includes at least one of the following: an adhesive, double-sided tape, plant-based adhesive, polyurethane composite adhesive, epoxy resin, curing agent, accelerator, water-based elastic paint, water-based resin, water-based environmentally friendly composite adhesive, flame retardant, and dispersant.

[0047] In one or more embodiments, the layers of the thermal insulation composite panel can be bonded together, for example, using an adhesive. Examples of adhesive materials include general-purpose super-adhesive types, general-purpose strong adhesive types, refrigerated food strong adhesive types, general-purpose re-peelable types, and fiber re-peelable types, but are not limited to these. It is preferable to use a material with low thermal conductivity.

[0048] The thermal insulation composite panel of the present invention preferably has a total thickness of 25 to 80 mm, and more preferably, considering its use as a thermal insulation layer for walls, it has two layers of aerogel felt with thicknesses of 10 mm each, resulting in an overall thickness of approximately 30 mm. This ensures thermal insulation and heat retention effects without occupying extra space, and the aforementioned physical bonding allows for excellent rigidity and tensile strength. The thermal insulation composite panel of the present invention preferably uses materials with a high fire resistance rating, with an overall fire resistance rating of A1, a thermal conductivity of 0.01 to 0.05, and an overall thermal conductivity of approximately 0.020. The thermal insulation composite panel as a whole may have various shapes, such as rectangular, square, circular, or hexagonal plates.

[0049] Figures 1 and 2 show a composite structure consisting of an inner outer layer 1, an intervening layer 2, an insulating and heat-retaining layer 3, another intervening layer 2, and an outer outer layer 4. However, the insulating and heat-retaining composite panel is not limited to this configuration; each layer may be a multi-layered composite structure, for example, each layer may have a structure of two or more layers.

[0050] At least one physical method can be used to join the layers, such as sutures, staples, rivets, bolts, engagements, and micro-hook attachments. Of course, chemical methods can also be used, such as adhesives, double-sided tapes, vegetable adhesives, polyurethane composite adhesives, epoxy resins, curing agents, accelerators, water-based elastic paints, water-based resins, water-based environmentally friendly composite adhesives, flame retardants, and dispersants.
