Description

Technical Field

[0001] This utility model relates to the field of mortar composite board technology, and more specifically, to aerogel composite inorganic thermal insulation mortar composite board. Background Technology

[0002] Currently, commonly used insulation boards in the building insulation field have many shortcomings. Traditional inorganic insulation mortar boards have limited insulation performance and cannot meet high energy-saving standards; while single aerogel insulation boards offer excellent insulation, they have low mechanical strength, are easily damaged during transportation and construction, and have poor adhesion to the building substrate. Furthermore, some composite insulation boards use a simple multi-layer stacking method, resulting in poor interlayer stability and a tendency for delamination and detachment over long-term use, affecting the overall service life and safety of the insulation system. To solve these problems, there is an urgent need to design a composite insulation board that combines excellent insulation performance, high mechanical strength, and stable interlayer connections. Utility Model Content

[0003] To overcome the above shortcomings, this utility model provides an aerogel composite inorganic thermal insulation mortar composite board, which aims to improve the problems that although single aerogel thermal insulation boards have excellent thermal insulation effects, they have low mechanical strength, are easily damaged during transportation and construction, and have poor adhesion to the building substrate.

[0004] This utility model is implemented as follows: an aerogel composite inorganic thermal insulation mortar composite board includes a base layer, a first adhesive layer, an aerogel thermal insulation layer, a second adhesive layer, an inorganic thermal insulation mortar layer, and a protective layer installed sequentially. The upper surface of the base layer has several evenly distributed grooves. The first adhesive layer fills the grooves and covers the upper surface of the base layer. The first adhesive layer is completely bonded to the lower surface of the aerogel thermal insulation layer. The upper surface of the aerogel thermal insulation layer has several protrusions. The second adhesive layer wraps around the protrusions and covers the upper surface of the aerogel thermal insulation layer. The second adhesive layer is completely bonded to the lower surface of the inorganic thermal insulation mortar layer. The upper surface of the inorganic thermal insulation mortar layer has several strip-shaped grooves. The lower surface of the protective layer has strip-shaped bosses adapted to the strip-shaped grooves, and the strip-shaped bosses engage with the strip-shaped grooves.

[0005] In a preferred embodiment of this utility model, the groove is hemispherical, the diameter of the groove is 5-8mm, the distance between two adjacent grooves is 10-15mm, and the base layer is a cement-based board.

[0006] In a preferred embodiment of this utility model, the protrusion is cylindrical, with a height of 3-5 mm, a diameter of 4-6 mm, and a distance of 8-12 mm between two adjacent protrusions.

[0007] In the preferred embodiment of this utility model, the width of the strip groove is 6-8mm, the depth is 4-5mm, and the distance between two adjacent strip grooves is 15-20mm.

[0008] In a preferred embodiment of this utility model, a plurality of glass fiber filaments are embedded in the aerogel insulation layer. The glass fiber filaments are arranged along the thickness direction of the aerogel insulation layer, and the two ends of the glass fiber filaments extend into the first adhesive layer and the second adhesive layer, respectively. The plurality of glass fiber filaments are arranged alternately with the plurality of protrusions.

[0009] In a preferred embodiment of this utility model, the protective layer is a polymer cement-based protective layer, and the thickness of the protective layer is 3-4 mm.

[0010] In a preferred embodiment of this utility model, symmetrical grooves are provided on both sides of the strip-shaped boss, a spring is fixedly installed on the inner wall of the groove, a plug is fixedly installed on one end of the spring, slots matching the plug are provided on both sides of the inner wall of the strip-shaped boss, the plug is slidably connected to the inner wall of the groove, and the bottom end of one side of the plug is inclined.

[0011] In a preferred embodiment of this utility model, a guide rod is fixedly installed on one side of the inner wall of the slide groove, and a circular hole matching the guide rod is provided on the insert block. The guide rod is slidably connected to the inner wall of the circular hole, and the spring is sleeved on the outside of the guide rod and corresponds to it one by one.

[0012] The beneficial effects of this utility model are: Synergistic improvement in thermal insulation performance and mechanical strength: The core insulation component, the aerogel insulation layer, inherently possesses excellent thermal insulation properties, meeting high energy-saving standards and overcoming the limitations of traditional inorganic thermal insulation mortar boards in terms of thermal insulation performance. Simultaneously, the glass fiber filaments embedded within the aerogel insulation layer are arranged along the thickness direction, extending to the first and second bonding layers at both ends. This not only enhances the aerogel insulation layer's own flexural and compressive strength, preventing damage during transportation and construction due to low mechanical strength, but also complements the strength of the inorganic thermal insulation mortar layer, giving the composite board both excellent thermal insulation performance and reliable structural strength.

[0013] The interlayer connection stability is significantly enhanced, eliminating the risk of delamination and detachment: The connection between each layer is strengthened through multiple structural designs. The hemispherical groove on the surface of the base layer allows the first adhesive layer to form a "fill anchor", which greatly improves the adhesion between the base layer and the aerogel insulation layer. The cylindrical protrusion on the upper surface of the aerogel insulation layer is embedded in the second adhesive layer, increasing the contact area between the two. The strip groove of the inorganic insulation mortar layer and the strip protrusion of the protective layer are matched and snapped together. In addition, the springs and plugs in the sliding grooves on both sides of the strip protrusion can automatically snap into the slots for stable fixation during installation. Combined with the cross-layer connection effect of glass fiber, the problem of poor interlayer connection and easy delamination and detachment caused by the simple superposition of multiple layers of traditional composite boards is completely solved, extending the overall service life of the insulation system.

[0014] High safety in construction and use, and strong environmental adaptability: The base layer uses cement-based boards, which provide a stable foundation for the composite board and ensure the load-bearing stability during construction; the protective layer is a 3-4mm thick polymer cement-based protective layer, which can effectively resist the erosion of the internal structure by external environmental factors such as moisture, dust, and minor impacts, reduce the impact of the external environment on the thermal insulation performance, and at the same time reduce the safety hazards caused by damage to the boards during use, thereby improving the adaptability and durability of the composite board in different building scenarios.

[0015] The structural design is precise and reasonable, and the performance is highly controllable: the dimensional parameters of each key component have been optimized and set, such as groove diameter of 5-8mm and spacing of 10-15mm, protrusion height of 3-5mm, diameter of 4-6mm and spacing of 8-12mm, and strip groove width of 6-8mm, depth of 4-5mm and spacing of 15-20mm. These precise dimensional designs ensure a balanced performance of the connection strength between layers, thermal insulation effect and structural stability, avoid performance fluctuations caused by improper dimensions, make the overall performance of the composite board easier to control, and stably meet the high standard requirements of building insulation projects.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] Please see Figures 1-4 This utility model provides a technical solution: an aerogel composite inorganic thermal insulation mortar composite board, comprising a base layer 110, a first adhesive layer 120, an aerogel thermal insulation layer 130, a second adhesive layer 140, an inorganic thermal insulation mortar layer 150, and a protective layer 160 installed sequentially. The upper surface of the base layer 110 has several evenly distributed grooves 111. The first adhesive layer 120 fills the grooves 111 and covers the upper surface of the base layer 110. The first adhesive layer 120 and the lower surface of the aerogel thermal insulation layer 130 are connected... The surfaces are completely bonded. The upper surface of the aerogel insulation layer 130 has multiple protrusions 131. The second adhesive layer 140 wraps around the protrusions 131 and covers the upper surface of the aerogel insulation layer 130. The second adhesive layer 140 is completely bonded to the lower surface of the inorganic insulation mortar layer 150. The upper surface of the inorganic insulation mortar layer 150 has several strip grooves 151. The lower surface of the protective layer 160 has strip bosses 161 that are adapted to the strip grooves 151. The strip bosses 161 are engaged with the strip grooves 151.

[0021] In some specific implementation schemes, the groove 111 is hemispherical with a diameter of 5-8 mm and a spacing of 10-15 mm between two adjacent grooves 111. This structure forms a more reliable "anchoring" connection, significantly improving the bonding strength between the base layer 110 and the first adhesive layer 120, thereby enhancing the connection stability between the base layer 110 and the aerogel insulation layer 130 and effectively preventing delamination between layers. The base layer 110 is a cement-based board, which itself has good load-bearing capacity, providing a stable foundation for the composite board as a whole and ensuring the structural stability of the composite board during transportation, construction and long-term use.

[0022] In some specific implementations, the protrusion 131 is cylindrical, with a height of 3-5 mm and a diameter of 4-6 mm. The distance between two adjacent protrusions 131 is 8-12 mm. The cylindrical protrusion 131 has a regular structure, which is convenient for processing and forming on the aerogel insulation layer 130, and can form a uniform contact interface with the second adhesive layer 140 to avoid stress concentration.

[0023] In some specific implementation schemes, the width of the strip groove 151 is 6-8mm and the depth is 4-5mm, which can precisely fit with the strip boss 161 on the lower surface of the protective layer 160. This ensures that the strip boss 161 can be smoothly inserted into the strip groove 151 and that there is sufficient contact area between the two, providing a good foundation for subsequent snap-fit ​​fixing. The distance between two adjacent strip grooves 151 is 15-20mm to avoid insufficient local connection force. When the strip boss 161 is snapped into the strip groove 151, it can make the protective layer 160 stably adhere to the inorganic thermal insulation mortar layer 150, effectively preventing the protective layer 160 from falling off and ensuring the overall structural integrity of the composite board.

[0024] In some specific implementations, a plurality of glass fiber filaments 132 are embedded within the aerogel insulation layer 130. The glass fiber filaments 132 are arranged along the thickness direction of the aerogel insulation layer 130. The glass fiber filaments 132 themselves possess high strength characteristics. After being embedded in the aerogel insulation layer 130, they can directly enhance the flexural and compressive strength of the aerogel insulation layer 130, solving the problems of low mechanical strength and easy damage during transportation and construction of the aerogel insulation layer 130. The two ends of the glass fiber filaments 132 extend into the first adhesive layer 120 and the second adhesive layer 140, respectively, to hold the aerogel insulation layer 130 in place. The aerogel insulation layer 130 is closely connected with the upper and lower adhesive layers, which greatly improves the integrity of the aerogel insulation layer 130 with the first adhesive layer 120 and the second adhesive layer 140, effectively avoiding interlayer delamination. The multiple glass fiber filaments 132 and multiple protrusions 131 are arranged in an alternating manner, which allows the reinforcing structure and the connecting structure of the aerogel insulation layer 130 to complement each other. This does not affect the connection effect between the protrusions 131 and the second adhesive layer 140, and allows the reinforcing effect of the glass fiber filaments 132 to uniformly cover the aerogel insulation layer 130, further optimizing the performance of the aerogel insulation layer 130.

[0025] In some specific implementation schemes, the protective layer 160 is a polymer cement-based protective layer with a thickness of 3-4 mm. The polymer cement-based material combines the flexibility of polymers with the strength of cement. As a protective layer 160, it can effectively resist the erosion of moisture and dust in the external environment, prevent the performance of internal layers (such as aerogel insulation layer 130 and inorganic insulation mortar layer 150) from deterioration due to moisture or contamination, and at the same time buffer minor external impacts to protect the internal structure from damage.

[0026] Please see Figure 5 The strip-shaped boss 161 has symmetrically arranged sliding grooves on both sides. A spring 162 is fixedly installed on the inner wall of each groove, and an insert block 163 is fixedly installed at one end of each spring 162. Slots matching the insert blocks 163 are provided on both sides of the inner wall of the strip-shaped boss 161. The insert blocks 163 slide against the inner wall of the groove. One bottom end of the insert block 163 is inclined, allowing it to retract inwards along the groove, achieving automatic avoidance without additional operation, facilitating installation. When the insert block 163 is inserted into the corresponding slot along with the strip-shaped boss 161, the spring 162 resets, pushing the insert block 163 into the slot, achieving automatic locking and fixing of the strip-shaped boss 161 and the strip-shaped groove 151. This eliminates the need for other fasteners, simplifying the installation process. Simultaneously, the locking structure effectively limits the relative displacement between the strip-shaped boss 161 and the strip-shaped groove 151, significantly improving the connection stability between the protective layer 160 and the inorganic thermal insulation mortar layer 150, and preventing the protective layer 160 from detaching during use.

[0027] In some specific implementation schemes, a guide rod 164 is fixedly installed on one side of the inner wall of the slide. The insert block 163 is provided with a round hole that matches the guide rod 164. The guide rod 164 is slidably connected to the inner wall of the round hole. The spring 162 is sleeved on the outside of the guide rod 164 and corresponds to it. The sliding cooperation between the guide rod 164 and the round hole of the insert block 163 provides precise guidance for the movement of the insert block 163, prevents the insert block 163 from deviating or getting stuck when moving in the slide, ensures that the insert block 163 can retract and pop out smoothly, and ensures the reliable operation of the snap-fit ​​structure.

[0028] Working principle: The base layer 110, as the foundation load-bearing layer of the composite board, uses cement-based board to provide stable support for the whole. The hemispherical grooves 111 (5-8mm in diameter, 10-15mm apart) on its surface can increase the contact area with the first adhesive layer 120. When the first adhesive layer 120 fills the grooves 111 and covers the upper surface of the base layer 110, it can form an "anchoring" effect, which can significantly improve the bonding strength between the base layer 110 and the aerogel insulation layer 130 and prevent the layers from separating. The aerogel insulation layer 130 is the core insulation component, which has excellent insulation performance. At the same time, the cylindrical protrusions 1 on the upper surface are also provided. 31 (height 3-5mm, diameter 4-6mm, spacing 8-12mm) can be embedded in the second adhesive layer 140 to increase the contact area between the aerogel insulation layer 130 and the second adhesive layer 140, and strengthen the connection stability between the two; and the glass fiber filaments 132 embedded in the aerogel insulation layer 130 along the thickness direction extend to the first adhesive layer 120 and the second adhesive layer 140 at both ends, which can enhance the mechanical strength of the aerogel insulation layer 130 itself and prevent it from being damaged during transportation and construction. On the other hand, the "cross-layer connection" further improves the integrity of the aerogel insulation layer 130 and the upper and lower adhesive layers and avoids delamination. The second adhesive layer 140 wraps around the protrusion 131 and covers the upper surface of the aerogel insulation layer 130, and is completely bonded to the lower surface of the inorganic insulation mortar layer 150. This not only transfers the insulation effect of the aerogel insulation layer 130, but also provides a stable adhesion base for the inorganic insulation mortar layer 150. The inorganic insulation mortar layer 150, while ensuring a certain level of insulation performance, also supplements the mechanical strength of the composite board. The strip grooves 151 (6-8mm wide, 4-5mm deep, 15-20mm spacing) on ​​its surface are adapted to the strip protrusions 161 on the lower surface of the protective layer 160. During installation, the strip-shaped boss 161 is inserted into the strip-shaped groove 151. At this time, the insert blocks 163 in the sliding grooves on both sides of the strip-shaped boss 161, due to the inclined bottom end on one side, will be squeezed by the inner wall of the strip-shaped groove 151 during the insertion process. They will retract along the guide rod 164 (slidably connected to the round hole of the insert block 163) into the sliding groove and compress the spring 162. When the insert block 163 moves to the slot position on the inner wall of the strip-shaped groove 151, the spring 162 returns to its original position and pushes the insert block 163 into the slot, realizing the snap-fit ​​fixation between the protective layer 160 and the inorganic thermal insulation mortar layer 150, preventing the protective layer 160 from falling off. The protective layer 160 is made of 3-4mm thick polymer cement-based material, covering the outermost layer, which can resist the erosion of the internal structure by factors such as moisture and impact in the external environment, protect the overall performance of the composite board, and extend its service life.

[0029] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
