[0003] Aerogel felt board or felt or roll products are widely used in aerospace industry and other aspects due to their excellent comprehensive performance such as non-combustibility, damping, and thermal insulation. However, the existing aerogel felt has defects such as loose, low surface strength, and severe powder loss, which limits the use of aerogel and only allows it to be used as a filler. Soft aerogel and surface powder often have poor load-bearing capacity and are difficult to withstand large loads or external force impact.

[0031] Embodiment one
[0032] As shown in Figure 1 and Figure 2 The utility model discloses a kind of aerogel felt hard composite boards, including heat-insulating material 1, reinforcing fiber mesh cloth 2, interface modification layer 5 and bonding coating 4;
[0033] Among them, reinforcing fiber mesh cloth 2 is laid on the upper and lower surfaces of heat-insulating material 1, heat-insulating material 1 includes aerogel felt, the heat-insulating material 1 is vertically penetrated together by stitching line 3 between the upper and lower reinforcing fiber mesh cloth 2 and is stitched, interface modification layer 5 is formed on the upper and lower reinforcing fiber mesh cloth 2 by coating aerogel special interface modifier, bonding coating 4 is formed on the surface of at least one interface modification layer 5 by coating bonding finish coating material, so that reinforcing fiber mesh cloth, stitching line 3 and heat-insulating material 1 are consolidated into the aerogel felt hard composite board of complete structure.
[0034] Among them, stitching line 3 is penetrated between the upper and lower reinforcing fiber mesh cloth 2 and is evenly arranged in multiple rows and / or multiple columns.
[0035] By laying reinforcing fiber mesh cloth on the two surfaces of aerogel felt heat-insulating material and vertically penetrating stitching by stitching line, the vertical pull strength, surface strength and hardness, flatness and connection firmness of composite board are improved, and the problem of segregation and stratification of heat-insulating material and reinforcing fiber mesh cloth is effectively solved.
[0036] As the main body of the composite board, high-performance aerogel felt is selected as the thermal insulation material 1. Aerogel has extremely low thermal conductivity and excellent lightweight properties, which ensures the excellent thermal insulation performance of the composite board. Preferably, the aerogel felt is treated to ensure its stability and durability while maintaining good air permeability to avoid internal water vapor accumulation.
[0037] The upper and lower reinforcing fiber meshes 2 are made of the same material with the same density, the same material with different densities, or different materials. The reinforcing fiber meshes 2 are made of glass fiber, basalt fiber, or alumina fiber. For example, to improve the overall strength and durability of the composite board, the upper and lower meshes are made of different materials. The upper mesh is made of carbon fiber mesh with excellent weather resistance to enhance wind pressure resistance and aging resistance. The lower mesh is made of glass fiber mesh with high strength and good toughness to improve the load-bearing capacity and impact resistance of the composite board. Both meshes are precisely woven to ensure uniform mesh distribution and significant reinforcement. Preferably, in this embodiment, the upper and lower reinforcing fiber meshes 2 are made of the same material, and the reinforcing fiber meshes 2 are made of glass fiber. The reinforcing fiber meshes 2 improve the surface strength and flatness of the aerogel felt hard composite board.
[0038] The upper and lower reinforcing fiber meshes 2 are first uniformly coated with an aerogel-specific interface modifier to form an interface modification layer, and then the outer surface of the interface modification layer is uniformly coated with a bonding and finishing material to form a bonding and covering layer 4. By coating the upper and lower reinforcing fiber meshes 2 with an aerogel-specific interface modifier to form an interface modification layer, the surface of the aerogel felt is modified, and the bonding and covering layer 4 is firmly bonded.
[0039] The thermal insulation material 1 and the upper and lower reinforcing fiber meshes 2 are stitched using a stitching process, specifically using multiple rows and columns of uniformly distributed carbon fiber stitches 3 for vertical stitching. The density of the vertical stitching carbon fiber stitches 3 can be selected according to actual needs. This stitching method not only ensures the tight bonding between the layers of the composite board, but also enhances the connection reliability and vertical pullout strength between the fiber meshes through the high-strength characteristics of the carbon fiber stitches, thereby enhancing the overall structural strength of the composite board.
[0040] In addition, the stitching line 3 can be made of one or more of carbon fiber stitches, glass fiber stitches, basalt fiber stitches, alumina fiber stitches, quartz fiber stitches, aramid fiber stitches, steel wire, blended fiber stitches, or recycled fibers (such as recycled polyester fibers). Preferably, in some applications, reinforcing meshes made of natural fibers (such as bamboo fiber and hemp fiber) can also be used to reduce dependence on virgin resources and reduce environmental pollution.
[0041] Preferably, one of the surfaces of the interface modification layer 5 on the upper and lower surfaces is coated with a bonding coating material to form a bonding coating layer 4, and the other surface of the interface modification layer 5 without the bonding coating material is integrally formed with the composite veneer panel to form a heat preservation and decoration integrated panel, wherein the veneer panel includes any one of calcium silicate board, aluminum metal veneer panel, A-grade non-combustible aluminum composite panel, ceramic sheet, and soft ceramic sheet.
[0042] Alternatively, the surfaces of the upper and lower interface modification layers 5 are both coated with a bonding coating material to form a bonding coating layer 4, and then a fireproof and crack-resistant layer is coated on the bonding coating layer 4, and a decorative mortar or stone-like coating layer is sprayed to form a heat preservation and decoration thin plaster integrated panel.
[0043] The vertical stitching solves the problem of delamination of the thermal insulation material 1 and the reinforcing fiber mesh cloth 2; the two-sided reinforcing fiber mesh cloth 2 and the bonding coating layer 4 integrally reinforce the loose and low-strength surface of the thermal insulation material 1, and improve the homogeneity and high compatibility, thereby enhancing the connection reliability between the thermal insulation material 1 and the reinforcing fiber mesh cloth 2.
[0044] The bonding coating layer 4 provides secondary waterproof and moisture-proof function for the porous and moisture-absorbing thermal insulation material 1, and completely seals the external fibers and dust, thereby eliminating dust pollution in the construction site and playing a positive role in haze control and emission reduction and worker health.
[0045] The fiber-forming felt is expanded from the previous single filling method to secondary composite bonding or anchoring of more composite methods, which greatly expands the application space and field of fiber boards.
[0046] Embodiment Two
[0047] On the basis of Embodiment One, the difference between Embodiment Two is that the bonding coating layer 4 of the aerogel felt hard composite board of Embodiment Two is further coated with a veneer coating layer 6, as shown in Figure 3 Preferably, the veneer coating layer 6 is one of real stone paint, stone-like paint, and inorganic paint, and can also be other types of paint. A functional layer 7 is further arranged between the veneer coating layer 6 and the bonding coating layer 4, wherein the functional layer 7 is at least one of a thermal insulation coating layer, a sound insulation coating layer, a waterproof protection layer, an air barrier film, and a reinforcing protection layer, thereby forming an integrated heat preservation and decoration panel.
[0048] The heat insulation coating layer effectively blocks the transfer of external heat, reducing the fluctuation of indoor temperature, thereby achieving the effect of heat preservation and insulation. The sound insulation coating layer further enhances the sound insulation capacity of the structure. It can effectively absorb and reflect sound waves, reducing the propagation of noise, and creating a more quiet and comfortable environment for the room. The waterproof protective layer as the outer structure has excellent waterproof performance. It can prevent the intrusion of external water such as rain and moisture, protect the internal layered structure from damage, and prolong the service life of the overall structure. The air-tight membrane (moisture-proof membrane) has a unique closed structure that can effectively isolate moisture and humidity in the air, preventing the internal structure from being damp, moldy or corroded. The close combination and interaction between the layers make the overall structure more solid and durable. This layered design not only improves the wind pressure resistance and impact resistance of the structure, but also enhances its weather resistance and corrosion resistance. The finishing coating layer as the outermost decorative layer can be selected in different colors, textures and patterns according to customer needs, thereby meeting individual aesthetic needs. It not only improves the overall aesthetic appearance, but also coordinates with the surrounding environment, creating a more harmonious and beautiful visual effect.
[0049] The aerogel felt hard composite board of the present application can be used with various market facing veneer panels such as ceramic veneer panels, aluminum veneer panels, and paint veneer panels, and can be applied to new buildings and existing building renovation envelope energy saving and emission reduction, and can also be applied to rock wool board thin plaster system, thin stone thermal insulation and decoration integrated panel, ceramic thin plate thermal insulation and decoration integrated panel, metal color steel sandwich, thermal insulation and structure integration, calcium silicate board sandwich thermal insulation and decoration integrated panel, special-shaped pipe wrapping and interlayer filling or building floor pasting anchoring, light weight high strength integrated panel and other application scenarios.
[0050] In summary, the integrated thermal insulation and decoration panel structure composed of the above layered structure has shown significant beneficial effects in terms of thermal insulation, sound insulation, waterproof protection, durability, construction convenience and aesthetic appearance. With its excellent thermal insulation performance, high-strength structure and rich decoration, it is particularly suitable for high-end residential buildings, commercial buildings, cold chain logistics warehouses and other places with extremely high requirements for thermal insulation, as a substitute for ceramic veneer panels, aluminum veneer panels or paint veneer panels, providing a more environmentally friendly, efficient and beautiful solution for modern buildings, not only improving the energy efficiency and living comfort of buildings, but also reducing construction and maintenance costs, and has wide application prospects and market value.
