Description

Technical Field

[0001] This utility model relates to the field of building insulation materials technology, and in particular to an exterior wall hydrophobic and breathable insulation board. Background Technology

[0002] In the construction industry, the performance of exterior wall materials is crucial to the overall quality and user experience of buildings. With the continuous development of the construction industry, the requirements for exterior wall insulation panels are also increasing. They not only need basic protective functions but also expect superior performance in terms of water repellency, breathability, and thermal insulation. High-quality exterior wall insulation panels can improve the durability of buildings, reduce the erosion of the building structure by the external environment, and create a more comfortable living and working environment indoors. This is of great significance in promoting the green and energy-saving development of the construction industry.

[0003] In the application of existing exterior wall insulation boards, various materials and methods are often used to achieve certain protection and functions. For hydrophobic functions, waterproof coatings are usually applied to the wall surface. These coatings form a waterproof film on the wall surface, preventing water intrusion. Waterproof mortar is also used, which forms a protective layer on the wall surface to enhance the wall's waterproof ability.

[0004] Regarding the aforementioned technologies, waterproof coatings primarily consist of polymer emulsions and asphalt. These organic materials are prone to molecular chain breakage under environmental factors such as light and temperature changes, leading to a loss of their original elasticity and adhesion, resulting in aging phenomena such as powdering and peeling. Waterproof mortar, as an inorganic material, is mainly composed of cement, sand, and waterproofing agents. After hardening, its volume shrinks, and the shrinkage stress can exceed the material's tensile strength, causing cracks and reducing its waterproofing effect. Utility Model Content

[0005] To improve the waterproof performance of the insulation board, this application provides an exterior wall hydrophobic and breathable insulation board.

[0006] This application provides a hydrophobic and breathable thermal insulation board for exterior walls, employing the following technical solution: An exterior wall hydrophobic and breathable thermal insulation board includes a body made of magnesium sulfate board. A shaped support mesh is provided inside the body. The shaped support mesh is embedded into the body through a hot pressing process to form a three-dimensional embedded structure. A waterproof and breathable layer is provided on one side of the body. The waterproof and breathable layer is bonded to the outer surface of the body through a prefabrication and bonding process. A thermal insulation layer is provided on the side of the body away from the waterproof and breathable layer.

[0007] By adopting the above technical solution, the shaped support mesh is embedded into the magnesium oxysulfate board through a hot-pressing process to form a three-dimensional embedded structure, which significantly improves the overall strength of the board and reduces deformation and cracking caused by temperature changes or external impacts. The insulation layer is located on the inner side of the board, directly blocking heat transfer. The magnesium oxysulfate board has advantages such as fire resistance, insect resistance, and corrosion resistance. When combined with the support mesh, it further improves the durability of the board and reduces later maintenance costs. The waterproof and breathable layer is bonded to the outer surface of the body through a prefabricated adhesive process to form a dense protective layer, which can effectively reduce rainwater intrusion while allowing water vapor to escape, avoiding the accumulation of condensate inside the wall and improving the waterproof performance of the insulation board.

[0008] Optionally, the shaping support mesh is composed of orthogonally arranged reinforcing ribs, which form a continuous grid structure inside the composite plate. The grid nodes are provided with barbed structures, and the barbed structures form a two-way tensile connection interface with the body.

[0009] By adopting the above technical solution, the orthogonally arranged reinforcing ribs form a regular grid skeleton, which evenly disperses external stress and reduces cracking or deformation caused by local stress concentration. This structure keeps the board flat during long-term use, reduces the risk of deformation caused by environmental factors, and the barbed structure forms a mechanical interlock with the magnesium oxysulfate board body, significantly improving interlayer bonding through the bidirectional tensile interface.

[0010] Optionally, a sound insulation layer is provided on the side of the insulation layer away from the main body, and the sound insulation layer has a number of sound absorption holes, which are evenly distributed along the surface of the sound insulation layer.

[0011] By adopting the above technical solution, the uniformly distributed sound-absorbing holes form a porous sound-absorbing structure. When sound waves are incident, some of the sound energy enters the pores and is consumed by internal friction, which is converted into heat energy, thereby reducing the transmission of indoor and outdoor noise.

[0012] Optionally, an adhesive layer is provided on the side of the sound insulation layer away from the thermal insulation layer, and the adhesive layer has adsorption properties.

[0013] By adopting the above technical solution, the adhesive layer can effectively bond the insulation board to the wall through its adsorption properties, simplifying the construction process. Construction workers only need to align the insulation board with the adhesive surface and press it gently to achieve a firm bond, thereby improving construction efficiency.

[0014] Optionally, a cushioning layer made of elastic material is provided on the side of the waterproof and breathable layer facing away from the main body.

[0015] By adopting the above technical solution, the buffer layer uses elastic materials, which can effectively absorb and disperse external impact forces. When the insulation board is subjected to collision, compression, or vibration, the buffer layer reduces direct damage to the insulation board through elastic deformation, thus extending the service life of the board.

[0016] Optionally, a finishing layer is provided on the side of the buffer layer away from the waterproof and breathable layer, and a guide channel is provided on the side of the finishing layer away from the buffer layer. The guide channel is inclined and runs through from top to bottom.

[0017] By adopting the above technical solution, the inclined guide channel uses gravity to quickly guide rainwater, condensate and other liquids to the outside of the insulation board, reducing the contact time between water and the waterproof and breathable layer and improving the hydrophobic performance of the insulation board.

[0018] Optionally, a number of water-absorbing blocks are fixed between the finishing layer and the buffer layer. The water-absorbing blocks are evenly distributed along the length of the finishing layer, and air-permeable channels are formed between the water-absorbing blocks. The water-absorbing blocks are filled with expanding water-absorbing material.

[0019] By adopting the above technical solution, the expandable water-absorbing material expands rapidly when it comes into contact with water. The expanded water-absorbing material fills the gaps inside the water-absorbing block, forming a physical barrier layer, which further reduces the possibility of external moisture penetrating into the interior through capillary action and improves the waterproof effect of the insulation board.

[0020] Optionally, the adhesive layer has an edge banding layer on both sides, with the edge banding layer extending to the adhesive layer and the finishing layer on both sides respectively. One side of the edge banding layer has several protrusions fixed on the opposite side, and the other side of the edge banding layer has grooves corresponding to the protrusions. When the insulation board is installed, the protrusions are inserted into the grooves of the adjacent insulation board.

[0021] By adopting the above technical solution, the edge-wrapping layer extends to the adhesive layer and the finishing layer, forming a waterproof flange that covers the edge of the board seam, reducing the seepage of moisture from the board seam. During the installation of the insulation board, the cooperation between the protrusions and the grooves can provide precise positioning for adjacent insulation boards, reducing the time and effort required to repeatedly adjust the position during installation and improving installation efficiency.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The waterproof and breathable layer is bonded to the outer surface of the body through a prefabricated adhesive process to form a dense protective layer, which can effectively reduce rainwater intrusion while allowing water vapor to escape, preventing condensation from accumulating inside the wall and improving the waterproof performance of the insulation board. 2. The buffer layer is made of elastic material, which can effectively absorb and disperse external impact force. When the insulation board is hit, squeezed or vibrated, the buffer layer reduces the direct damage to the insulation board through elastic deformation, thus extending the service life of the board. 3. The fit between the protrusions and grooves provides precise positioning for adjacent insulation boards, reducing the time and effort required for repeated adjustments during installation and improving installation efficiency.

Detailed Implementation

[0028] The present application will be further described in detail below with reference to all the accompanying drawings.

[0029] This application discloses an external wall hydrophobic and breathable thermal insulation board. Example

[0030] Reference Figure 1 and Figure 2 A hydrophobic and breathable thermal insulation board for exterior walls includes a body 1, which is made of magnesium oxysulfate board. The magnesium oxysulfate board gives the insulation board good fire resistance, moisture resistance and environmental protection performance. The body 1 is provided with a shaping support mesh 11, which is embedded in the magnesium oxysulfate board through a hot pressing process to form a three-dimensional interlocking structure, which significantly improves the overall strength of the board and reduces the probability of deformation and cracking caused by temperature changes or external impact, thereby increasing the service life of the board.

[0031] Reference Figure 3 and Figure 4 The shaping support mesh 11 is composed of orthogonally arranged reinforcing ribs, which form a continuous grid structure inside the composite board, evenly distributing external stress and reducing cracking or deformation caused by local stress concentration. This structure keeps the board flat during long-term use and reduces the risk of deformation caused by environmental factors. The grid nodes are equipped with barbed structures, which form a mechanical interlock with the magnesium oxysulfate board body 1. The bidirectional tensile interface significantly improves the interlayer bonding force and reduces the probability of separation between the shaping support mesh 11 and the body 1.

[0032] Reference Figure 2One side of the main body 1 is provided with an insulation layer 3, which effectively blocks heat transfer and improves the insulation performance of the insulation board. The side of the main body 1 away from the insulation layer 3 is provided with a waterproof and breathable layer 2. The waterproof and breathable layer 2 is bonded to the outer surface of the main body 1 through a prefabrication and bonding process to form a dense protective layer, which can effectively reduce rainwater intrusion while allowing water vapor to escape, preventing the accumulation of condensate inside the wall and improving the waterproof performance of the insulation board.

[0033] Reference Figure 2 and Figure 3 A sound insulation layer 4 is provided on the side of the insulation layer 3 facing away from the main body 1. The sound insulation layer 4 has several sound-absorbing holes 41, which are evenly distributed along the surface of the sound insulation layer 4 to form a porous sound-absorbing structure. When sound waves are incident, some sound energy enters the pores and is consumed by internal friction, converting into heat energy, which can reduce the transmission of indoor and outdoor noise. At the same time, the sound insulation layer 4, the insulation layer 3, and the main body 1 form a composite sound insulation system. The magnesium oxysulfate board itself has a high density, which can block low-frequency sound waves. The insulation layer 3 further attenuates sound energy through material damping, and the sound insulation layer 4 is optimized for mid-to-high frequency noise. The three work together to achieve wide-band sound insulation.

[0034] Reference Figure 2 and Figure 3 The sound insulation layer 4 has an adhesive layer 5 on the side opposite to the thermal insulation layer 3. The adhesive layer 5 can effectively bond the thermal insulation board to the wall through its adsorption properties, simplifying the construction process. Construction workers only need to align the thermal insulation board with the adhesive surface and press it gently to achieve bonding, thereby improving construction efficiency.

[0035] Reference Figure 2 A buffer layer 6 is provided on the side of the waterproof and breathable layer 2 facing away from the main body 1. The buffer layer 6 is made of elastic material, which can effectively absorb and disperse external impact forces. When the insulation board is subjected to collision, compression or vibration, the buffer layer 6 reduces direct damage to the insulation board through elastic deformation, thus extending the service life of the board.

[0036] Reference Figure 2 The buffer layer 6 has several absorbent blocks 7 on the side opposite to the waterproof and breathable layer 2. These absorbent blocks are evenly distributed along the surface of the buffer layer 6, forming ventilation channels between them to ensure the breathability of the insulation board and allow water vapor inside the wall to escape. The absorbent blocks 7 are filled with expanding absorbent material. When the absorbent blocks 7 come into contact with water, they expand rapidly. The expanded absorbent material fills the gaps inside the absorbent blocks 7, forming a physical barrier layer that further reduces the possibility of external moisture penetrating into the interior through capillary action, thereby improving the waterproof effect of the insulation board.

[0037] Reference Figure 1 and Figure 2A finishing layer 8 is provided on the side of the absorbent block 7 facing away from the buffer layer 6. The finishing layer 8 covers all the absorbent blocks 7. The surface of the finishing layer 8 is coated with a fire-retardant coating, which can resist corrosion from acid rain, salt spray and other substances, and maintain its fire-retardant performance for a long time. At the same time, ultraviolet absorbers are added to the fire-retardant coating to reduce the risk of aging and cracking of the finishing layer 8. A guide channel 81 is provided on the side of the finishing layer 8 facing away from the buffer layer 6. The guide channel 81 is inclined from top to bottom and uses gravity to quickly guide rainwater, condensate and other liquids to the outside of the insulation board, reducing the contact time between water and the waterproof and breathable layer 2, and further improving the hydrophobic performance of the insulation board.

[0038] Reference Figure 1 and Figure 2 The adhesive layer 5 has edge-sealing layers 9 on both sides, extending to the adhesive layer 5 and the finishing layer 8 respectively. The edge-sealing layers 9 form a waterproof flange, covering the edges of the board seams and reducing moisture seepage. One side of the edge-sealing layer 9 has several protrusions 82 fixed to its opposite side, while the other side has grooves 83 corresponding to the protrusions 82. During insulation board installation, the cooperation between the protrusions 82 and the grooves 83 provides precise positioning for adjacent insulation boards. Construction workers can quickly insert the protrusions 82 of one insulation board into the grooves 83 of another, accurately aligning the two boards and reducing the time and effort spent on repeated adjustments, thus improving installation efficiency. Simultaneously, the tight cooperation between the protrusions 82 and the grooves 83 restricts the relative displacement of adjacent insulation boards in both the horizontal and vertical directions. In long-term use, this effectively reduces problems such as enlarged joint gaps and poor sealing caused by insulation board displacement, thereby maintaining the overall performance of the insulation system.

[0039] The implementation principle of the exterior wall hydrophobic and breathable insulation board in this application embodiment is as follows: the expandable water-absorbing material expands rapidly after encountering water, and the expanded water-absorbing material fills the internal gaps of the water-absorbing block 7 to form a physical barrier layer, reducing the probability of external liquids penetrating into the interior. The edge-wrapping layer 9 forms a waterproof flange, covering the edge of the board seam, reducing the seepage of water from the board seam. The waterproof and breathable layer 2 is bonded to the outer surface of the body 1 through a prefabricated adhesive process to form a dense protective layer, which can effectively reduce rainwater intrusion, while allowing water vapor to escape, avoiding the accumulation of condensate inside the wall, and improving the waterproof performance of the insulation board.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
