Description

Technical Field

[0001] This utility model relates to a novel high-efficiency phase change insulation board material structure and an energy-saving wall structure containing the same. Background Technology

[0002] Building insulation is a crucial aspect of energy-saving insulation and has always attracted widespread attention. Currently, the main methods involve applying building insulation materials to the exterior or interior of the building envelope, or using self-insulating wall materials for construction, to enhance the building's thermal insulation effect and thus achieve energy-saving goals. The insulation performance of the insulation material directly affects the building's energy-saving effectiveness. However, in addition to insulation performance, from a safety perspective, if the insulation material can meet Class A fire resistance requirements while ensuring insulation effectiveness, it will further help ensure fire safety during construction and use.

[0003] Traditional thermal insulation materials often face the dilemma of simultaneously achieving excellent thermal insulation and fire resistance. Organic insulation materials like XPS and EPS, while offering excellent thermal insulation, suffer from significant shortcomings in fire resistance. Inorganic insulation materials, such as rock wool, foam glass, and inorganic modified non-combustible boards, while achieving Class A fire resistance, lack ideal thermal insulation performance. To address this challenge, composite insulation materials, composed of organic and inorganic materials in a combined form, have emerged. Although composite panels alleviate the conflict between fire resistance and thermal insulation to some extent, their multi-layered structure creates the safety hazard of delamination and detachment. Currently, there is an urgent need to develop a new type of fire-resistant insulation board that is structurally safer and more reliable, meets Class A fire resistance standards, and achieves superior thermal insulation performance, thus meeting the pressing needs of building energy conservation and safety.

The phase change insulation component is made of a phase change material or a composite insulation material containing a phase change material.

[0007] Furthermore, the structure of the novel high-efficiency phase change insulation board material also includes reinforcing components, which are disposed within the insulation board.

[0028] Reinforced component 3 Detailed Implementation

[0029] The following description of the embodiments is with reference to the accompanying drawings, which illustrate specific embodiments in which the present invention can be implemented.

[0030] Example 1

[0031] This embodiment discloses an energy-saving wall structure, which includes a novel high-efficiency phase change insulation board material structure. For example... Figure 1 As shown, the structure of this novel high-efficiency phase change insulation board material includes an insulation board 1 and at least one phase change insulation component 2. The insulation board 1 is made of an organic-inorganic composite material, and its fire resistance rating reaches Class A. The insulation board 1 has at least one filling cavity 11, which is prefabricated through the insulation board 1 during its preparation. The phase change insulation component 2 corresponds one-to-one with the filling cavity 11 and is filled within the filling cavity 11. The phase change insulation component 2 is made of a phase change material or a composite insulation material containing a phase change material. The insulation board 1, made of an organic-inorganic composite material, achieves a Class A fire resistance rating, thus combining insulation performance with fire resistance. Furthermore, during the preparation of the insulation board 1, the filling cavity 11 is prefabricated through the insulation board 1, and then the phase change insulation component 2 is filled into the filling cavity 11, thereby further optimizing the insulation performance of the novel high-efficiency phase change insulation board material structure. The phase change insulation component 2 is made of phase change material or composite insulation material containing phase change material and is filled into the filling cavity 11. This allows the heat absorption and release properties of the phase change material to be utilized to further optimize the overall insulation effect and achieve better energy saving.

[0032] The filling cavity 11 can extend through the insulation board 1 along its length or width, further optimizing the overall insulation effect and achieving better energy saving. Multiple filling cavities 11 are arranged at intervals and connected to each other within the insulation board 1. Alternatively, multiple filling cavities 11 can be arranged crosswise and interconnected.

[0033] The filling cavity 11 within the insulation board 1 can be prepared by processing a hollow tube or a mold. By placing a hollow tube inside the organic-inorganic composite material, the internal space of the hollow tube can form the filling cavity 11; alternatively, a mold can be placed inside the organic-inorganic composite material and then removed outward to form the filling cavity 11. The shape of the filling cavity 11 can be cylindrical or cuboid, and the specific shape is not limited.

[0034] In insulation board 1, the organic-inorganic composite material is composed of organic and inorganic materials. The organic material is pre-foamed expandable polystyrene granules, and the inorganic material is wrapped around the organic material. By using pre-foamed expandable polystyrene granules as the organic material and wrapping the inorganic material around it, it is possible to ensure that, with the same thickness of insulation material, the fire resistance reaches A2 level, the strength meets the relevant product standard requirements, and it is lightweight, eliminating the need for additional inorganic composite boards to enhance its strength and fire resistance. The material of insulation board 1 can be graphene insulation material.

[0035] The insulation board 1 has an inwardly recessed connecting reinforcement groove on its side. This groove effectively increases the connection area between the insulation board 1 and other structures, thereby further strengthening the connection between the insulation board 1 and other structures. This effectively prevents the new high-efficiency phase change insulation board material from falling off, greatly improving the safety and reliability of the energy-saving wall structure. The connecting reinforcement groove can be provided on one side of the insulation board 1 or on both sides.

[0036] Example 2

[0037] like Figure 2As shown, the structural similarities between the novel high-efficiency phase change insulation board material of this embodiment and that of Embodiment 1 will not be repeated; only the differences will be explained. In this Embodiment 2, the insulation board 1 consists of an outer layer 12 and an inner layer 13. The outer layer 12 and the inner layer 13 are prepared by layering and molding the raw material slurry in a single step. The outer layer 12 and the inner layer 13 are composed of organic-inorganic composite materials with different strengths and thermal conductivity. The inorganic materials in the organic-inorganic composite materials used in the outer layer 12 and the inner layer 13 are of the same type. The outer layer 12 and the inner layer 13 are cast into a mold. Since both the outer layer 12 and the inner layer 13 are organic-inorganic composite materials, the fire resistance rating of the insulation board 1 reaches Class A, effectively providing fire protection and eliminating the fire hazards of the novel high-efficiency phase change insulation board material structure. The inorganic materials in the organic-inorganic composite materials used in the outer layer 12 and the inner layer 13 are of the same type, which can overcome the risk of delamination and cracking caused by different materials due to different raw material sources during later use. At the same time, the layered fabrication and one-time molding process adopted in the preparation and production process can more effectively avoid delamination and cracking between the layers and problems such as water seepage and detachment that may occur later, compared with the later connection scheme composed of adhesive materials, which greatly improves the safety and stability of the new high-efficiency phase change insulation board material structure.

[0038] The outer layer 12 and the inner layer 13 are manufactured in layers using a unified casting process. The order of casting in the mold is not limited; the outer layer 12 can be cast first, followed by the inner layer 13, or the inner layer 13 can be cast first, followed by the outer layer 12, thus achieving the processing and manufacturing of a novel high-efficiency phase change insulation board material structure. Preferably, the outer layer 12 and the inner layer 13 are prepared by a one-time molding process.

[0039] In this embodiment 2, the compressive strength of the inner layer 13 is greater than that of the outer layer 12, enabling the insulation board 1 to provide reliable material strength support. The thermal conductivity of the outer layer 12 is better than that of the inner layer 13, significantly improving the thermal insulation performance of the insulation board 1. Simultaneously, this effectively enhances the strength, thermal insulation effect, and fire resistance of the insulation board 1, ensuring that the strength, thermal insulation effect, and fire resistance of the novel high-efficiency phase change insulation board material structure meet the requirements.

[0040] Example 3

[0041] like Figure 3As shown, the identical parts of the novel high-efficiency phase change insulation board material structure in this embodiment to those in Embodiment 2 will not be repeated; only the differences will be explained. In this Embodiment 3, the novel high-efficiency phase change insulation board material structure also includes a reinforcing component 3, which is disposed within the insulation board 1. The reinforcing component 3 has a reinforcing function. During the prefabrication of the insulation board 1 in the factory, the reinforcing component 3 is pre-installed within the insulation board 1 and formed as a whole. The reinforcing component 3 can enhance the strength of the novel high-efficiency phase change insulation board material structure, greatly improving its stability.

[0042] The reinforcing component 3 may include reinforcing ribs, which are installed within the insulation board 1 for easy installation. The reinforcing component 3 may also include a reinforcing mesh, specifically a mesh-like structure composed of vertical and horizontal reinforcing ribs. The reinforcing component 3 may also include a reinforcing mesh frame, specifically a mesh frame-like structure composed of vertical, horizontal, and diagonal reinforcing ribs forming a reinforcing mesh cage.

[0043] In this embodiment 3, the reinforcing member 3 is located inside the outer layer 12. Of course, the reinforcing member 3 can also be located inside the inner layer 13. Alternatively, part of the reinforcing member 3 can be located inside the outer layer 12, while the rest can be located inside the inner layer 13. The position and number of the reinforcing members 3 are not limited.

[0044] In this embodiment 3, the reinforcing component 3 can be made of metal, and a metal reinforcing component 3 can ensure its reinforcing effect. The reinforcing component 3 can also be made of glass fiber or fiber-reinforced composite material, that is, the reinforcing component 3 can be made of high-strength thermal insulation materials such as glass fiber or FRP (Fiber Reinforced Polymer / Plastic), which effectively improves the stability of the new high-efficiency phase change insulation board material structure; at the same time, it avoids thermal bridging.

[0045] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
