Description

Technical Field

[0001] This utility model relates to the field of insulation board technology, specifically a moisture-proof composite insulation board for use in humid environments. Background Technology

[0002] Insulation boards are building materials whose core function is to reduce heat transfer. They are mainly used in building walls, roofs, floors, and other parts. By reducing heat conduction efficiency, they can stabilize indoor temperature and reduce the energy consumption of air conditioning, heating, and other equipment. They are a key material in the field of building energy conservation.

[0003] However, existing moisture-proof composite insulation boards still have some problems in use:

[0004] An existing example is a moisture-proof composite insulation board with application number CN201220353519.4, which includes an extruded polystyrene board and a mesh cloth pasted on the upper and lower surfaces of the extruded polystyrene board. The composite insulation board also includes a coke layer and a wire mesh. The coke layer is pasted on the mesh cloth with adhesive, and the wire mesh is pasted on the coke layer on the lower surface of the extruded polystyrene board with adhesive.

[0005] Existing moisture-proof insulation boards mostly rely on a single moisture-proof layer design. In long-term humid environments, their moisture-proof effect is limited and cannot meet actual usage needs. Furthermore, the overall structural strength and stability need to be improved, making it difficult to meet the long-term usage requirements in complex humid environments.

[0006] Therefore, we propose a moisture-proof composite insulation board for humid environments to solve the problems mentioned above. Utility Model Content

[0007] The purpose of this utility model is to provide a moisture-proof composite insulation board for humid environments, in order to solve the problems mentioned in the background art, which mostly rely on a single moisture-proof layer design. In long-term humid environments, the moisture-proof effect is limited and cannot meet the actual use requirements. Furthermore, the overall structural strength and stability need to be improved, making it difficult to meet the long-term use requirements in complex humid environments.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a moisture-proof composite insulation board for humid environments, comprising a protective outer layer and a moisture-proof intermediate layer.

[0009] The outer protective layer is filled with a moisture-proof intermediate layer, which includes a moisture-proof film. The inner side of the moisture-proof film is filled with absorbent cotton strips. The inner side of the moisture-proof intermediate layer is filled with a heat-insulating core layer, and the outer surface of the heat-insulating core layer is tightly connected to the inner side of the absorbent cotton strips. A reinforcing layer is bonded to the inside of the heat-insulating core layer. The reinforcing layer includes an elastic buffer plate, and a support frame is provided inside the elastic buffer plate.

[0010] The above technical solution achieves efficient moisture protection through multiple layers: the outer protective layer initially blocks external physical impacts, the moisture-proof membrane in the middle moisture-proof layer prevents most moisture penetration, and the absorbent cotton strips absorb a small amount of infiltrated moisture. The core insulation layer reduces heat transfer by utilizing its low thermal conductivity, while the elastic buffer plate and support frame in the reinforcement layer work together to buffer external forces and enhance the overall structural strength. This effectively resists the impact of humid environments on the insulation board, maintains stable insulation performance, and improves the structural reliability and service life of the insulation board in humid environments where it may be subjected to external forces.

[0011] Preferably, the protective outer layer includes a metal plate, and a groove is formed at the outer edge of the metal plate, and the groove has a ring structure.

[0012] Using the above technical solution, the metal plate material has high strength and deformation resistance, and can withstand certain external impacts to protect the internal structure; the ring structure design of the slot is based on the splicing and installation requirements, and uses a specific shape to realize the interlocking connection of adjacent plates. The metal plate effectively resists external physical damage and reduces the probability of the insulation board being damaged by external forces; the ring slot facilitates the quick and accurate splicing of adjacent insulation boards, improves construction efficiency and ensures the stability of the overall structure.

[0013] Preferably, the moisture-proof film is designed with four layers along the interior of the moisture-proof intermediate layer, and sixteen sets of absorbent cotton strips are evenly distributed vertically between the moisture-proof films.

[0014] Using the above technical solution, the four-layer moisture-proof film is based on the principle of multi-layer barrier, which greatly increases the resistance to water penetration by stacking layers; the sixteen evenly distributed absorbent cotton strips utilize the characteristics of absorbent materials to form a multi-point water absorption network, which can quickly absorb a small amount of water that seeps in; the four-layer moisture-proof film effectively prevents water from penetrating, greatly reducing the risk of internal dampness; the sixteen absorbent cotton strips absorb and store a small amount of water in a timely manner, ensuring that the core insulation layer is always in a dry state and maintaining the stability of the insulation board performance.

[0015] Preferably, the insulation core layer includes a rock wool board, and the rock wool board has multiple hollow channels inside, and the channels are arranged in a honeycomb pattern.

[0016] By adopting the above technical solution, hollow channels arranged in a honeycomb pattern are opened inside the rock wool board. Taking advantage of the extremely low thermal conductivity of air, heat is reduced through the rock wool board, significantly improving the thermal insulation performance of the core insulation layer, effectively reducing heat exchange, and meeting the high requirements for thermal insulation performance in humid environments.

[0017] Preferably, the support frame is arranged in a grid pattern along the interior of the elastic buffer plate.

[0018] Using the above technical solution, the grid-shaped cross-arranged support frame can decompose the external force into multiple directions. The elastic buffer plate itself has elastic deformation capability, and together with the support frame, it forms a buffer system. Through its own elasticity, it buffers the impact of external forces. The grid-shaped structure of the support frame enhances the overall structural strength of the insulation board, enabling it to withstand greater pressure and impact. Working in synergy with the elastic buffer plate, it effectively absorbs and disperses external forces, reduces the risk of damage to the internal structure, and extends the service life of the insulation board.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. The outer metal plate of the protective layer can effectively resist external physical damage and protect the internal structure from damage. At the same time, the ring groove on its outer edge facilitates the splicing and installation between the plates and improves construction efficiency. The four layers of moisture-proof film in the moisture-proof middle layer greatly reduce the possibility of water penetration, while the sixteen evenly distributed water-absorbing cotton strips can absorb the small amount of water that seeps in in time, ensuring that the core insulation layer is always in a dry state. This effectively avoids the decline in insulation performance and damage to the internal structure caused by moisture, and extends the service life of the insulation board.

[0021] 2. The elastic buffer plate in the reinforcement layer works in conjunction with the internal grid-shaped cross-bracing support frame. The elastic buffer plate can buffer the impact of external forces, while the support frame can disperse the external forces, thereby enhancing the overall structural strength and deformation resistance of the insulation board. This allows it to maintain stable performance and good structural integrity even in humid environments where it may be subjected to external forces, providing reliable insulation and protection for the building.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] Please see Figures 1-5 This utility model provides a technical solution: a moisture-proof composite insulation board for humid environments, comprising a protective outer layer 1 and a moisture-proof intermediate layer 2. The protective outer layer 1 is filled with the moisture-proof intermediate layer 2, which includes a moisture-proof film 201. Absorbent cotton strips 202 are filled inside the moisture-proof film 201. An insulation core layer 3 is filled inside the moisture-proof intermediate layer 2, and the outer surface of the insulation core layer 3 is tightly bonded to the inner surface of the absorbent cotton strips 202. A reinforcing layer 4 is bonded inside the insulation core layer 3, comprising an elastic buffer plate 401, with a support frame 402 inside the elastic buffer plate 401. The protective outer layer 1 includes a metal plate 101, with a groove 102 at its outer edge, and the groove 102 has a ring structure. The moisture-proof film 201 is designed in four layers along the interior of the moisture-proof intermediate layer 2, and sixteen sets of absorbent cotton strips 202 are evenly distributed vertically along the moisture-proof film 201. The insulation core layer 3 includes a rock wool board 301, and the rock wool board 301 has multiple hollow channels inside, which are arranged in a honeycomb pattern. The support frame 402 is distributed in a grid pattern along the inside of the elastic buffer plate 401.

[0030] The outer protective layer 1, with its high-strength metal plate 101, resists external physical impacts, reducing the probability of damage to the insulation board due to external forces. The annular groove 102 on the outer edge facilitates quick and precise splicing of adjacent insulation boards, improving construction efficiency and overall structural stability. The moisture-proof intermediate layer 2 contains four layers of moisture-proof film 201 that block moisture penetration, greatly reducing the risk of internal dampness. Sixteen evenly distributed absorbent cotton strips 202 can promptly absorb any small amount of infiltrated moisture, ensuring that the core insulation layer 3 remains dry and maintaining the stability of the insulation board's performance. The rock wool board 301 of the core insulation layer 3, with its high strength, effectively... Its low thermal conductivity and internal honeycomb-shaped hollow channels effectively reduce heat transfer, significantly improving the thermal insulation performance of the core insulation layer 3, effectively reducing heat exchange, and meeting the high requirements for insulation performance in humid environments. The elastic deformation of the elastic buffer plate 401 in the reinforcement layer 4, together with the internal grid-shaped cross-arranged support frame 402, absorbs and disperses external impacts, enhances the structural strength and deformation resistance of the insulation board, reduces the risk of internal structural damage, extends the service life of the insulation board, and enables the insulation board to have good moisture resistance, thermal insulation and structural stability in humid environments.

[0031] Working principle: For this type of moisture-proof composite insulation board used in humid environments, during operation, the metal plate 101 of the outer protective layer 1 resists external impacts and other physical forces with its own strength. The annular groove 102 on its outer edge facilitates engagement and splicing with adjacent insulation boards to form an overall protective structure. When external moisture attempts to penetrate, the four layers of moisture-proof film 201 in the moisture-proof middle layer 2 block the moisture layer by layer. If a small amount of moisture still seeps in, the sixteen sets of absorbent cotton strips 202 evenly distributed between the moisture-proof films 201 will quickly absorb the moisture and prevent it from penetrating further. The rock wool board 301 of the insulation core layer 3 effectively reduces heat transfer and maintains insulation performance by utilizing its low thermal conductivity and internal honeycomb-shaped hollow channels. When the insulation board is impacted by external force, the elastic buffer plate 401 in the reinforcing layer 4 undergoes elastic deformation to buffer the external force. At the same time, the internal grid-shaped cross-arranged support frame 402 disperses the external force, enhances the overall structural strength of the insulation board, and avoids damage to the internal structure.

[0032] This completes a series of tasks. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0033] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
