Description

Technical Field

[0001] This utility model relates to the field of polystyrene extruded boards, and more specifically, to aerogel composite polystyrene extruded boards. Background Technology

[0002] In existing building insulation applications, extruded polystyrene (XPS) boards often fail to meet increasingly stringent energy-saving requirements due to the limited insulation performance of this single material. When connected to walls or other substrates, improper bonding structure design can easily lead to insufficient local adhesion, hollow areas, and detachment. Furthermore, the lack of targeted reinforcement in the internal structure allows heat to be quickly transferred through the substrate, resulting in poor insulation performance and an inability to achieve a good balance between insulation performance and structural connection capabilities.

[0003] How to invent aerogel composite polystyrene extruded boards to improve these problems has become an urgent issue for those skilled in the art. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an aerogel composite polystyrene extruded board, which aims to improve the existing polystyrene extruded board. Due to the limited thermal insulation performance of the single material, it is difficult to meet the energy-saving requirements. The bonding structure is prone to local insufficient adhesion, hollowing and falling off. The lack of targeted reinforcement design leads to rapid heat transfer and poor thermal insulation effect.

[0005] This utility model is implemented as follows: an aerogel composite polystyrene extruded board includes an extruded polystyrene board base layer, an aerogel layer is provided on one side surface of the extruded polystyrene board base layer, a number of bonding holes are opened on the other side surface of the extruded polystyrene board base layer, and a number of heat-insulating cavities extending along its length are opened inside the extruded polystyrene board base layer, and each heat-insulating cavity is filled with aerogel blocks.

[0006] In a preferred embodiment of this utility model, a plurality of uniformly distributed positioning posts are provided on one side surface of the extruded polystyrene board base layer where the aerogel layer is provided, and the aerogel layer simultaneously covers all positioning posts and one side surface of the extruded polystyrene board base layer.

[0007] In a preferred embodiment of this invention, the outer wall of each aerogel block is tightly fitted to the inner wall of the corresponding insulation cavity.

[0008] In a preferred embodiment of this utility model, a plurality of the heat-insulating cavities are evenly distributed along the width direction of the extruded polystyrene board base layer.

[0009] In a preferred embodiment of this utility model, the number of bonding holes in each group is multiple and they are distributed in a plum blossom pattern.

[0010] In a preferred embodiment of this invention, each of the bonding holes is a blind hole.

[0011] In a preferred embodiment of this utility model, an annular buffer groove is provided inside the extruded polystyrene board base layer on the outside of all the insulation cavities, and an elastic buffer strip is embedded in the annular buffer groove.

[0012] The beneficial effects of this utility model are as follows: The aerogel composite polystyrene extruded board obtained by the above design, when used, combines an aerogel layer on one side of the extruded polystyrene board base layer with multiple sets of bonding holes, an internal insulation cavity, and filled aerogel blocks on the other side of the base layer. By utilizing the synergistic effect of the extruded polystyrene board and the aerogel material, a multi-level insulation structure is constructed, which improves the overall insulation performance and effectively reduces heat transfer.

[0016] 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.

[0017] Please see Figures 1 to 4 This utility model provides a technical solution: an aerogel composite polystyrene extruded board, including an extruded polystyrene board base 1, an aerogel layer 2 on one side surface of the extruded polystyrene board base 1, a plurality of bonding holes 101 on the other side surface of the extruded polystyrene board base 1, and a plurality of heat-insulating cavities 102 extending along its length direction inside the extruded polystyrene board base 1, each heat-insulating cavity 102 being filled with aerogel blocks 3.

[0018] Please see Figures 2 to 4 On one side surface of the extruded polystyrene board base layer 1, which is provided with an aerogel layer 2, there are also several evenly distributed positioning posts 104. The aerogel layer 2 covers all the positioning posts 104 and one side surface of the extruded polystyrene board base layer 1.

[0019] On one side of the extruded polystyrene board base layer 1 where the aerogel layer 2 is located, several positioning posts 104 are set using an integral molding process or by drilling and inserting posts later. The positioning posts 104 can be cylindrical, prismatic, etc., and are evenly distributed. During the processing of the aerogel layer 2, a pressing process is used to ensure that the aerogel material covers all the positioning posts 104 and one side of the extruded polystyrene board base layer 1, ensuring that the positioning posts 104 are completely embedded in the aerogel layer 2, forming a mechanical interlocking structure. The interlocking of the positioning posts 104 and the aerogel layer 2 improves the connection strength between the two and reduces the risk of the aerogel layer 2 falling off; the evenly distributed positioning posts 104 make the aerogel layer 2 more evenly stressed, extending the overall service life of the material.

[0020] Furthermore, the outer wall of each aerogel block 3 is tightly fitted to the inner wall of the corresponding insulation cavity 102.

[0021] During the fabrication of the insulation cavity 102, the inner wall of the cavity is made smooth and regular. When prefabricating the aerogel block 3, its dimensions are matched to the insulation cavity 102, ensuring a close fit between the outer wall of the block and the inner wall of the cavity. When filling the aerogel block 3, slight pressure and vibration can be used to ensure the block fully fills the cavity and achieves a tight fit. If small gaps exist, aerogel slurry can be added to fill them densely. This tight-fitting structure effectively blocks air convection heat transfer within the cavity, enhancing the insulation effect; it also prevents the aerogel block 3 from shaking or shifting within the cavity, ensuring long-term structural stability and maintaining consistent insulation performance.

[0022] Furthermore, several thermal insulation cavities 102 are evenly distributed along the width direction of the extruded polystyrene board base layer 1.

[0023] Based on the width of the extruded polystyrene board base layer 1, the number of insulation cavities 102 is determined and they are evenly distributed along the width direction. During processing, these insulation cavities 102 are formed in one step using a mold, ensuring precise cavity positioning and uniform spacing. The evenly distributed insulation cavities 102 allow for more balanced heat transfer along the width direction of the base layer, improving the overall uniformity of insulation; it also facilitates mold design and standardized production during manufacturing, reducing process difficulty and ensuring product consistency.

[0024] Furthermore, each group of bonding holes 101 consists of multiple holes distributed in a quincunx pattern.

[0025] Each group of bonding holes 101 has a central hole surrounded by multiple holes arranged in a circular array, forming a quincunx pattern. During processing, drilling equipment is used to drill holes on the surface of the extruded polystyrene board base layer 1 according to the preset quincunx array coordinates. The spacing and depth of the holes are controlled to ensure that each group of bonding holes 101 is regular in shape and precisely distributed. The quincunx distribution allows the adhesive force to diffuse from the center outwards, dispersing local stress and improving bonding reliability. Compared to other distribution forms, it allows for a more reasonable layout of the bonding holes 101 within the same base layer area, enhancing connection stability while reducing excessive weakening of the base layer structure strength.

[0026] Furthermore, each bonding hole 101 is a blind hole.

[0027] When machining the bonding hole 101, the drilling depth is controlled so that one end of the hole opens onto the surface of the extruded polystyrene board base layer 1 where bonding is required, while the other end is a closed blind end that does not penetrate the base layer to the aerogel layer 2. The blind hole structure blocks the intrusion path of adverse external factors, protects the composite surface of the aerogel layer 2 and the internal insulation cavity 102, aerogel block 3 from moisture and contamination, and maintains long-term insulation performance.

[0028] Furthermore, an annular buffer groove 103 is provided inside the extruded polystyrene board base layer 1 on the outside of all the insulation cavities 102, and an elastic buffer strip 4 is embedded in the annular buffer groove 103. The elastic buffer strip 4 has a circular arc structure in cross section.

[0029] Inside the extruded polystyrene board base layer 1, along the outer edge of all insulation cavities 102, there is an annular buffer groove 103. The groove has a circular arc cross-section, and its depth is adjusted according to the thickness of the base layer. For example, when the base layer thickness is 3cm, the groove depth is 0.5-1.5cm. An elastic buffer strip 4 is processed into an arc shape to fit the annular buffer groove 103 and installed into the groove using embedding or bonding methods, ensuring a tight fit between the elastic buffer strip 4 and the inner wall of the groove without loosening. The annular buffer groove 103 and the elastic buffer strip 4 work together to effectively buffer the deformation stress of the base layer, improving the structure's crack resistance. The arc-shaped cross-section of the elastic buffer strip 4 results in more uniform stress distribution, strong deformation recovery ability, and is less prone to failure over long-term use, ensuring the overall structural stability of the extruded polystyrene board.

[0030] Working principle: The extruded polystyrene board base layer 1 serves as the basic support and insulation carrier. An aerogel layer 2 on one side enhances the insulation on one side. Positioning posts 104 are embedded in the aerogel layer 2 to form a mechanical interlock, improving the interlayer connection strength and preventing the aerogel layer 2 from detaching. On the other side, blind holes 101 distributed in a quincunx pattern not only disperse bonding stress and enhance the stability of the connection with the external base layer, but also, because the blind holes do not penetrate the base layer, block the intrusion path of external moisture and impurities from the bonding surface. Together with the base material layer, they form physical isolation and structural support for the aerogel layer 2. Internally... In the insulation cavity 102, which extends along its length and is evenly distributed, the tightly fitted aerogel blocks 3 work together with the base layer and aerogel layer 2 to form a multi-level insulation system, improving the overall heat insulation effect. The annular buffer groove 103 and elastic buffer strip 4 located on the outside of the insulation cavity 102 can absorb the deformation stress of the base layer caused by temperature changes and external forces, prevent the base layer edge from cracking, and indirectly protect the aerogel layer 2 and other structures. Through the synergy of various components, efficient heat insulation, reliable connection and structural protection are achieved, ensuring the stable performance of the aerogel layer 2 and giving full play to the heat insulation function of the composite extruded board.

[0031] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
