Description

Technical Field

[0001] The present invention relates to the technical field of building thermal insulation, and more particularly to a vacuum thermal insulation board and a preparation device thereof. Background Art

[0002] As building energy-saving standards rise, exterior wall insulation has become a critical component. Vacuum insulation panels, with their extremely low thermal conductivity, excellent fire resistance, lightweight and water-resistant properties, hold great potential for application in building exterior wall insulation. Combining an inorganic core material with a composite membrane, they effectively block heat transfer through air convection and can also reduce wall thickness to expand usable area. Current building exterior wall construction often uses adhesive mortar to secure vacuum insulation panels. This method relies solely on the surface adhesion between the materials to resist external loads, lacking a locking structure to distribute the load in three dimensions. As a result, in actual engineering applications, the bonded interface of the vacuum insulation panels is unable to withstand the long-term effects of complex environmental loads and is prone to hollowing and falling off. In light of this, we propose a vacuum insulation panel and a device for its preparation. Summary of the Invention

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Example

[0021] like Figure 1-2 As shown, a vacuum insulation panel comprises a heat sealing layer 1 and an arc-shaped core material layer 2, the heat sealing layer 1 is made of polyethylene material, the core material layer 2 is a composite of aerogel and glass fiber, a sealed vacuum chamber 3 is formed inside the heat sealing layer 1, the core material layer 2 is located in the vacuum chamber 3, the outside of the heat sealing layer 1 is bonded and coated with an aluminum foil barrier layer 4, the outside of the aluminum foil barrier layer 4 is bonded and coated with a reinforced protective layer 5, one layer of the reinforced protective layer 5 is bonded to the outside with an anchoring layer 6, the anchoring layer 6 is an arc-shaped structure corresponding to the core material layer 2, a plurality of evenly arranged slurry feed grooves 7 are provided at the bottom of the anchoring layer 6, the inner diameter of the opening of the slurry feed groove 7 gradually shrinks to the other end to form an "eight"-shaped structure, a plurality of evenly arranged anchoring grooves 8 are provided inside the anchoring layer 6, the anchoring groove 8 is a semicircular structure, the anchoring grooves 8 are respectively connected to the inside of the slurry feed groove 7, and symmetrical anchoring parts 9 are formed on both sides of the connection between the anchoring groove 8 and the slurry feed groove 7.

[0022] Specifically, the core material layer 2 is composed of a composite of aerogel and glass fiber. The low thermal conductivity of aerogel can effectively block heat conduction, while the glass fiber enhances the structural strength and prevents deformation of the core material. The heat sealing layer 1 is made of polyethylene material and forms a sealed vacuum chamber 3 to isolate air from entering to maintain a vacuum state, thereby significantly reducing heat loss. The aluminum foil barrier layer 4 outside the heat sealing layer 1 blocks heat radiation with its high reflectivity. Its dense structure can also be moisture-proof and air-tight, preventing the internal material from aging and moisture. The outermost reinforced protective layer 5 can resist mechanical damage and has properties such as UV resistance and acid and alkali resistance, protecting the internal structure from environmental erosion. From the core insulation of the core material layer 2, to the heat sealing layer 1 and the vacuum chamber 3 blocking heat transfer, to the aluminum foil barrier layer 4 reflecting heat radiation and the reinforced protective layer 5 providing external protection, each layer cooperates with each other to enable it to have excellent thermal insulation performance and durability when used on the exterior walls of buildings. The anchoring layer 6 bonded to the outside of the reinforced protective layer 5 makes it possible for the inner wall of the mortar inlet groove 7 opened on the anchoring layer 6 to squeeze the bonding mortar when it is installed on the exterior wall of the building, and the inner diameter of the opening of the mortar inlet groove 7 gradually shrinks toward the other end to form an "eight"-shaped structure, so that the inner diameter of the mortar inlet groove 7 gradually becomes smaller, and the amount of bonding mortar it can accommodate becomes smaller and smaller until the bonding mortar enters the anchoring groove 8, thereby guiding the bonding mortar and reducing the probability that the bonding mortar entering the mortar inlet groove 7 cannot fill the anchoring groove 8 due to a small amount. The anchoring groove 8 is a semicircular structure. When After the bonding mortar solidifies, a semicircular structure corresponding to the anchor groove 8 will be formed, and the anchoring parts 9 formed on both sides of the connection between the anchor groove 8 and the slurry inlet groove 7 can block the solidified bonding mortar at this time, thereby forming a riveted structure, thereby increasing the stability after installation and reducing the probability of falling off. The arc-shaped anchoring layer 6 and the core material layer 2 can play a certain buffering effect when impacted, thereby increasing its overall strength of use, and the arc-shaped anchoring layer 6 can have a gathering effect on the bonding mortar when squeezing the bonding mortar, further increasing the effect of the bonding mortar filling the slurry inlet groove 7 and the anchor groove 8.

[0023] Furthermore, a plug-in portion 10 is formed between each of the two adjacent pulp inlet grooves 7. The plug-in portion 10 is a trapezoidal structure that is narrow at the bottom and wide at the top.

[0024] Specifically, when the plug-in portion 10 , which is narrow at the bottom and wide at the top, contacts the bonding mortar, it can be inserted into the bonding mortar, and after the bonding mortar solidifies and dries, the stability of the fixation between the anchoring layer 6 and the bonding mortar is further increased.

[0025] like Figure 3-13As shown, a preparation device for a vacuum insulation board, which is used to prepare any of the above-mentioned vacuum insulation boards, includes a base 11, the top of the base 11 is fixedly connected to a shell 12, the top of the base 11 is fixedly connected to a plurality of guide pillars 13, the guide pillars 13 are located inside the shell 12, the top of the guide pillars 13 is fixedly connected to a supporting plate 14, the top of the supporting plate 14 is fixedly connected to a first telescopic cylinder 15, one end of the first telescopic cylinder 15 passes through the supporting plate 14 to its bottom and is fixedly connected to a lower pressing plate 16, and the lower pressing plate 16 is penetrated by the guide pillars 13 and is slidably connected to it, a pressing plate 17 is provided at the bottom of the lower pressing plate 16, a supporting plate 18 is provided at the top of the base 11, the top of the supporting plate 18 is fixedly connected to a pressing seat 19, a pressing groove 20 is provided on the top of the pressing seat 19, the bottom of the pressing groove 20 is an arc structure, and a plurality of abutments 21 are fixedly connected to the bottom of the pressing groove 20.

[0026] Specifically, because the core material layer 2 and the anchoring layer 6 are both arc-shaped structures, and a plug-in portion 10 is formed between the slurry inlet groove 7, when the anchoring layer 6 is pressed against the core material layer 2 protected by the reinforcing protective layer 5, the anchoring layer 6 is subjected to pressure and is easily deformed. The plug-in portion 10 directly supports the anchoring layer 6 under the force, and is also prone to deformation or even fracture due to uneven stress distribution. Therefore, by placing the anchoring layer 6 in the pressing groove 20 with an arc-shaped structure at the bottom, and then evenly applying adhesive on the bonding surface of the anchoring layer 6, the core material layer 2 covered with the reinforced protective layer 5 is placed on the bonding surface of the anchoring layer 6, and then the pressing seat 19 is moved to the bottom of the pressing plate 17 by the support plate 18, and the lower pressure plate 16 is pushed down by the first telescopic cylinder 15, so that the lower pressure plate 16 drives the pressing plate 17 to move toward the core material layer 2, thereby applying pressure to the core material layer 2. In this process, an abutment 21 is provided inside the pressing groove 20, and the abutment 21 passes through the slurry feed groove 7 to the anchoring groove 8, and the inner wall of the anchoring groove 8 is supported by the abutment 21. Therefore, when the core material layer 2 is subjected to force and fits with the anchoring layer 6, neither the core material layer 2 nor the anchoring layer 6 will be deformed, and the plug-in part 10 is not subjected to force, which can also prevent the plug-in part 10 from being damaged.

[0027] Furthermore, the top of the abutment 21 extends to both sides to form an arc-shaped abutment portion 22, and both sides of the abutment portion 22 are hinged with an arc-shaped adapter portion 23. After the adapter portion 23 is twisted, it cooperates with the abutment portion 22 to form a semicircular structure corresponding to the inner wall of the anchor groove 8. The bottom of the abutment 21 is provided with a movable cavity 24, and the inner wall of the movable cavity 24 is slidably connected to a push plate 25. The top of the push plate 25 extends to form symmetrical plate ears 26, and a lower push rod 27 is provided between the plate ears 26. The two ends of the lower push rod 27 rotate with the opposite side between the plate ears 26 The outer wall of the lower push rod 27 is rotatably connected with a plurality of connecting plates 28, and the end of the adapter 23 away from the abutting portion 22 is provided with a receiving groove 29, and an upper push rod 30 is provided inside the receiving groove 29. The two ends of the upper push rod 30 are respectively rotatably connected with the inner walls on both sides of the receiving groove 29, and the outer wall of the abutting member 21 is provided with symmetrically arranged movable grooves 31 connected to the movable cavity 24. The other ends of the connecting plates 28 are rotatably connected with the two upper push rods 30 in sequence, and the bottom of the pressing seat 19 is provided with a thrust mechanism for controlling the movement of the push plate 25.

[0028] Specifically, the thrust mechanism is provided to push the push plate 25 upward in the movable chamber 24. The push plate 25 will drive the plate ear 26 to move upward during the upward movement, and the upward movement of the plate ear 26 will drive the lower push rod 27 to move upward. The lower push rod 27 will push the connecting plate 28 during the upward movement, so that the other end of the connecting plate 28 pushes the upper push rod 30. The upper push rod 30 is set in the receiving groove 29, and the receiving groove 29 is opened on the adapter 23. Therefore, when the upper push rod 30 is pushed, the upper push rod 30 will push the adapter 23 to twist on the abutment portion 22, thereby Instead, the adapter part 23 and the abutment part 22 cooperate to form a semicircular structure corresponding to the inner wall of the anchoring groove 8, so that the adapter part 23 and the abutment part 22 push the inner wall of the anchoring groove 8 at the same time, thereby increasing the support effect on the anchoring layer 6. When the anchoring layer 6 is supported, the force area of ​​the anchoring layer 6 is increased, the support effect is increased, and the probability of the anchoring layer 6 being damaged due to the stress generated during compression is further reduced. By allowing the adapter part 23 to twist freely, the adapter part 23 can be prevented from being blocked by the anchoring part 9 due to twisting and unable to be pulled out or inserted into the anchoring groove 8.

[0029] Furthermore, the thrust mechanism includes a linkage groove 32 that passes through the support plate 18, and a linkage plate 33 is provided inside the linkage groove 32. The top of the linkage plate 33 is a semicircular structure, and a plurality of convex columns 34 are provided at the bottom of the linkage plate 33. The top of the convex column 34 passes through the linkage plate 33 and is slidably connected thereto, and the top of the convex column 34 is fixedly connected to the bottom of the pressing seat 19, and the bottom of the push plate 25 is fixedly connected to a movable plate 35. The other end of the movable plate 35 passes through the pressing seat 19 to its bottom and abuts against the top of the linkage plate 33. The bottom of the linkage plate 33 is fixedly connected to an upper guide block 36, and the bottom of the base 11 is fixedly connected to a lower guide block 37. The lower guide block 37 is located at the bottom of the pressing plate 17. The bottom of the upper guide block 36 is provided with a guide groove 38 with a gradually inclined top inner wall, and the top of the lower guide block 37 is a guide portion 39 corresponding to the guide groove 38.

[0030] Specifically, when the support plate 18 drives the pressing seat 19 to move to the bottom of the pressing plate 17, the linkage plate 33 is connected to the bottom of the pressing seat 19 through the convex column 34, so the linkage plate 33 will move together, and the bottom of the linkage plate 33 is fixedly connected by the upper guide block 36. During the movement of the upper guide block 36, the guide groove 38 at the bottom thereof will gradually contact the guide portion 39 at the top of the lower guide block 37, and the top inner wall of the guide groove 38 is gradually inclined, and the top of the guide portion 39 is in contact with the top inner wall of the guide groove 38. The walls correspond to each other, so at this time the guide portion 39 will gradually push the upper guide block 36 through the top inner wall of the guide groove 38, so that the upper guide block 36 moves up to drive the linkage plate 33 to move up, so that the linkage plate 33 pushes the movable plate 35 during the upward movement, thereby causing the movable plate 35 to move up and push the push plate 25, causing the push plate 25 to move up. Similarly, when the support plate 18 is reset, the upper guide block 36 is reset, and the push plate 25 and the movable plate 35 are reset under their own gravity, causing the adapter 23 to reset and twist.

[0031] Furthermore, a pair of guide rails 40 are fixedly connected to the top of the base 11, and symmetrically arranged sliders 41 are slidably connected to the guide rails 40. The other end of the slider 41 is fixedly connected to the bottom of the support plate 18. An electric telescopic rod 42 is fixedly connected to the inner wall of the base 11, and the other end of the electric telescopic rod 42 is fixedly connected to a "U"-shaped transmission member 43. A transmission groove 44 connected to the interior of the base 11 is provided at the top of the base 11, and the top of the transmission member 43 passes through the transmission groove 44 and is fixedly connected to the bottom of the support plate 18.

[0032] Specifically, the transmission member 43 is driven to move by the electric telescopic rod 42, and the top of the transmission member 43 passes through the transmission slot 44 and is fixedly connected to the bottom of the support plate 18, and a pair of guide rails 40 are fixedly connected to the top of the base 11. The guide rails 40 support the support plate 18 through the slider 41, so when the transmission member 43 moves, it will drive the support plate 18 to move, thereby realizing the free movement of the support plate 18.

[0033] Furthermore, the top of the lower pressure plate 16 is fixedly connected to a symmetrically arranged second telescopic cylinder 45, one end of the second telescopic cylinder 45 passes through the lower pressure plate 16 and is fixedly connected to the top of the pressing plate 17, the bottom of the lower pressure plate 16 is fixedly connected to a sealing cover 46 corresponding to the support plate 18, and the sealing cover 46 sleeves the pressing plate 17 inside, the top of the lower pressure plate 16 is fixedly connected to a vacuum pump 47, and the air inlet of the vacuum pump 47 is connected to the interior of the sealing cover 46.

[0034] Specifically, when the first cylinder is extended, it drives the lower pressure plate 16 to move downward, and the downward movement of the lower pressure plate 16 drives the sealing cover 46 to move downward, so that the sealing cover 46 is in contact with the support plate 18, so that the pressing seat 19 is located in the sealed space formed between the support plate 18 and the sealing cover 46. The extension of the second telescopic cylinder 45 can drive the pressing plate 17 to pressurize the anchoring layer 6 and the core material layer 2 covered by the reinforced protective layer 5, and the air in the space is extracted by the vacuum pump 47 to make it a negative pressure, thereby removing bubbles in the adhesive on the surface of the anchoring layer 6, and further increasing the bonding effect between the anchoring layer 6 and the core material layer 2 covered by the reinforced protective layer 5.

[0035] Furthermore, a sealing groove 48 corresponding to the bottom frame of the sealing cover 46 is formed on the top of the supporting plate 18 , and a sealing ring 49 is fixedly connected to the bottom inner wall of the sealing groove 48 .

[0036] Specifically, by providing a sealing groove 48 and a sealing ring 49 in the sealing groove 48 , the sealing cover 46 is inserted into the sealing groove 48 and abuts against the sealing ring 49 during the downward movement, thereby increasing the sealing effect between the sealing cover 46 and the support plate 18 .

[0037] Furthermore, a fitting portion 50 is extended from the bottom of the pressing plate 17 , and the bottom of the fitting portion 50 is an arc-shaped structure corresponding to the bottom of the pressing groove 20 .

[0038] Specifically, the arc-shaped bonding portion 50 formed by extension squeezes the core material layer 2 covered by the reinforced protective layer 5, thereby further increasing the contact effect and the uniformity of the pressure distribution during the pressing process.

[0039] Furthermore, a rubber cushion 51 is fixedly connected to the bottom of the fitting portion 50 , and the bottom of the cushion 51 is frosted.

[0040] Specifically, the buffer pad 51 is provided to protect the core material layer 2 and prevent the core material layer 2 from being scratched or damaged.

[0041] Working principle: This embodiment provides a vacuum insulation board. The core material layer 2 is composed of a composite of aerogel and glass fiber. The extremely low thermal conductivity of aerogel can effectively block heat conduction, while the glass fiber enhances the structural strength and prevents deformation of the core material. The heat sealing layer 1 is made of polyethylene material. By forming a sealed vacuum chamber 3, air is isolated from entering to maintain a vacuum state, which greatly reduces heat loss. The aluminum foil barrier layer 4 outside the heat sealing layer 1 blocks heat radiation with its high reflectivity. Its dense structure can also be moisture-proof and air-tight, preventing the internal material from aging and moisture. The outermost reinforced protective layer 5 can resist mechanical damage and has the characteristics of UV resistance, acid and alkali resistance, etc., protecting the internal structure from environmental erosion. From the core insulation of the core material layer 2, to the heat sealing layer 1 and the vacuum chamber 3 blocking heat transfer, to the aluminum foil barrier layer 4 reflecting heat radiation and the reinforced protective layer 5 providing external protection, each layer cooperates with each other to make it have excellent thermal insulation performance and durability when used on the exterior wall of a building. The anchoring layer 6 bonded to the outside of the reinforced protective layer 5 makes it possible for the inner wall of the mortar inlet groove 7 opened on the anchoring layer 6 to squeeze the bonding mortar when it is installed on the exterior wall of the building, and the inner diameter of the opening of the mortar inlet groove 7 gradually shrinks toward the other end to form an "eight"-shaped structure, so that the inner diameter of the mortar inlet groove 7 gradually becomes smaller, and the amount of bonding mortar it can accommodate becomes smaller and smaller until the bonding mortar enters the anchoring groove 8, thereby guiding the bonding mortar and reducing the probability that the bonding mortar entering the mortar inlet groove 7 cannot fill the anchoring groove 8 due to a small amount. The anchoring groove 8 is a semicircular structure. When After the bonding mortar solidifies, a semicircular structure corresponding to the anchor groove 8 will be formed, and the anchoring parts 9 formed on both sides of the connection between the anchor groove 8 and the slurry inlet groove 7 can block the solidified bonding mortar at this time, thereby forming a riveted structure, thereby increasing the stability after installation and reducing the probability of falling off. The arc-shaped anchoring layer 6 and the core material layer 2 can play a certain buffering effect when impacted, thereby increasing its overall strength of use, and the arc-shaped anchoring layer 6 can have a gathering effect on the bonding mortar when squeezing the bonding mortar, further increasing the effect of the bonding mortar filling the slurry inlet groove 7 and the anchor groove 8.

Ordinary technicians in this field can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. As long as they do not deviate from the spirit of the present invention, they are all within the scope of protection of the present invention.
