Technical Field

[0001] This utility model relates to the field of building materials technology, and in particular to a building insulation material. Background Technology

[0002] Building insulation materials work by taking measures on the building's external envelope to reduce the loss of heat from the interior to the exterior, thereby maintaining the building's indoor temperature. Building insulation materials play an important role in creating a suitable indoor thermal environment and saving energy in building insulation.

[0003] For example, Chinese patent CN213014754U discloses a building thermal insulation and waterproof material, including a first plate, second plates symmetrically arranged on the upper and lower side walls of the first plate, a third plate fixedly connected to the side wall of the two second plates separated from each other, a fourth plate arranged on the side wall of the two third plates separated from each other, a fifth plate fixedly connected to the side wall of the two fourth plates separated from each other, and a plurality of first mounting strips fixedly connected to the side wall of the two fifth plates separated from each other.

[0004] However, existing building materials generally lack functionality. They rely solely on the insulation performance of a single insulation material, which cannot meet various requirements. There is a lack of highly efficient thermal insulation materials, resulting in generally poor actual insulation performance and low overall practical application value. To address these issues, a new building insulation material is proposed. Utility Model Content

[0005] The purpose of this utility model is to solve the problems that existing building materials have limited functionality, rely solely on the insulation performance of a single insulation material, cannot meet multiple requirements, lack efficient thermal insulation materials, have mediocre actual insulation performance, and have low overall practical application value. Therefore, this utility model proposes a building insulation material.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a building insulation material, comprising a base wall, a curtain wall keel, and an exterior wall finish layer, wherein an insulation layer is fixedly connected to one side of the curtain wall keel, and a crack-resistant protective layer is fixedly connected to the other side of the curtain wall keel; the insulation layer comprises a phenolic foam layer, a fiber glass wool board, and a thermal insulation board; one side of the fiber glass wool board is bonded to the phenolic foam layer, and the other side of the fiber glass wool board is bonded to the thermal insulation board; the thermal insulation board comprises an air-barrier sealing layer, the interior of which is filled with a core material; the inner wall of the air-barrier sealing layer is uniformly provided with multiple gas adsorption layers, and the outer wall of the air-barrier sealing layer is provided with an air-barrier film.

[0007] Preferably, the crack-resistant protective layer includes a polymer plastering mortar layer one, thermal insulation anchors and a polymer plastering mortar layer two, and an alkali-resistant fiberglass mesh is provided on one side of the polymer plastering mortar layer one.

[0008] Preferably, one side of the polymer plastering mortar layer two is provided with alkali-resistant fiberglass mesh cloth two, and one side of the polymer plastering mortar layer one is fixedly connected to the polymer plastering mortar layer two by multiple thermal insulation anchors.

[0009] Preferably, one side of the polymer plastering mortar layer two is provided with an alkali-resistant fiberglass mesh fabric two.

[0010] Preferably, a polymer surface treatment agent is provided on one side of the phenolic foam layer, and one side of the crack-resistant protective layer is fixedly connected to the inner side of the exterior wall cladding layer.

[0011] Preferably, one side of the base wall is provided with adhesive mortar, and one side of the base wall is bonded to the phenolic foam layer by the adhesive mortar.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, by setting up a heat insulation board, the heat insulation board is composed of a gas barrier sealing layer, a core material, a gas adsorption layer, and a gas barrier film. The high gas barrier film has excellent fracture resistance and impermeability. The core material is preferably gas-phase SiO2, which not only ensures the heat insulation performance, but also realizes the ultra-thin design of the board. This not only improves the heat insulation effect of the board, but also significantly extends the service life of the ultra-thin vacuum heat insulation board. The gas adsorption agent in the gas adsorption layer is a metal-based composite material, which reduces the thermal conductivity of the heat insulation board and ensures its long-term and efficient heat insulation performance, thereby improving the heat insulation performance of the building material. At the same time, by forming a vacuum state inside the board, the heat insulation board significantly reduces the heat transfer caused by air convection, thereby effectively reducing the building's energy consumption. It can also effectively block the three heat transfer modes of heat radiation, heat conduction, and heat convection, significantly improving the building's energy efficiency.

[0014] 2. In this utility model, by setting a phenolic foam layer and a fiber glass wool board, the phenolic foam layer has the advantages of low thermal conductivity, good thermal insulation performance, fire resistance, flame retardancy, non-toxicity, green environmental protection and sound insulation. At the same time, the fiber glass wool board is an ultra-fine fiber glass wool board, which has the advantages of low thermal conductivity, good thermal insulation performance and sound absorption and noise reduction.

[0020] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1: As Figure 1 - Figure 3 As shown, this utility model provides a building insulation material, including a base wall 1, a curtain wall keel 4, and an exterior wall finishing layer 6. An insulation layer 3 is fixedly connected to one side of the curtain wall keel 4, and a crack-resistant protective layer 5 is fixedly connected to the other side of the curtain wall keel 4. The insulation layer 3 includes a phenolic foam layer 32, a fiber glass wool board 33, and a thermal insulation board 34. One side of the fiber glass wool board 33 is bonded to the phenolic foam layer 32, and the other side of the fiber glass wool board 33 is bonded to the thermal insulation board 34. A polymer surface treatment agent 31 is provided on one side of the phenolic foam layer 32. One side of the crack-resistant protective layer 5 is fixedly connected to the inner side of the exterior wall finishing layer 6. An adhesive mortar 2 is provided on one side of the base wall 1, and the base wall 1 is bonded to the phenolic foam layer 32 through the adhesive mortar 2.

[0023] The specific settings and functions of this embodiment are described below: The phenolic foam layer 32 has the advantages of low thermal conductivity, good thermal insulation performance, fire resistance, flame retardancy, non-toxicity, green environmental protection and sound insulation. At the same time, the fiber glass wool board 33 is an ultra-fine fiber glass wool board, which has the advantages of low thermal conductivity, good thermal insulation performance and sound absorption and noise reduction.

[0024] Example 2: Figure 1 and Figure 4As shown, the thermal insulation board 34 includes an air-barrier sealing layer 35, the interior of which is filled with a core material 36. Multiple gas adsorption layers 37 are uniformly arranged on the inner wall of the air-barrier sealing layer 35, and an air-barrier film 38 is arranged on the outer wall of the air-barrier sealing layer 35. The crack-resistant protective layer 5 includes a polymer plastering mortar layer 1 51, thermal insulation anchors 53, and a polymer plastering mortar layer 2 54. An alkali-resistant fiberglass mesh 52 is arranged on one side of the polymer plastering mortar layer 1 51, and an alkali-resistant fiberglass mesh 55 is arranged on one side of the polymer plastering mortar layer 2 54. One side of the polymer plastering mortar layer 1 51 is fixedly connected to the polymer plastering mortar layer 2 54 by multiple thermal insulation anchors 53, and an alkali-resistant fiberglass mesh 55 is arranged on one side of the polymer plastering mortar layer 2 54.

[0025] The overall effect of this embodiment is that the high gas barrier film 38, formed by thermally bonding materials such as PE, aluminum foil, fiberglass cloth, and PET into a multilayer composite film, possesses excellent fracture resistance and impermeability. The core material 36 can be selected from open-cell polystyrene foam, fumed SiO2, open-cell polyurethane, precipitated SiO2, and fiberglass wool, etc. Taking fumed SiO2 as an example, its average pore size is approximately 20nm, providing a low thermal conductivity of up to 0.004W / (m·K). Simultaneously, the thickness of the core material 36 is controlled within 5mm, ensuring both thermal insulation performance and achieving an ultra-thin design. This not only improves the thermal insulation effect of the board but also significantly extends the service life of the ultra-thin vacuum insulation panel. The getter in the sublayer 37 is made of metal-based composite material (such as magnesium-aluminum alloy particles). Through special treatment, it can adsorb residual gas inside the board and maintain the stability of the vacuum state. Approximately 5g of getter is provided per square meter of insulation board. The getter can effectively maintain the vacuum degree inside the board below 0.005Pa, further reducing the thermal conductivity of the insulation board and ensuring its long-term high-efficiency thermal insulation performance, thereby improving the thermal insulation performance of the building material. At the same time, the insulation board 34 significantly reduces heat transfer caused by air convection by creating a vacuum state inside the board, thereby effectively reducing the building's energy consumption. It can also effectively block the three heat transfer modes of heat radiation, heat conduction and heat convection, significantly improving the building's energy efficiency.

[0026] The usage and working principle of this device: The building insulation material consists of a base wall 1, bonding mortar 2, insulation layer 3, curtain wall keel 4, crack-resistant protective layer 5, and exterior wall finishing layer 6. By adding insulation layer 3, which is mainly composed of phenolic foam layer 32, fiber glass wool board 33, and thermal insulation board 34, the phenolic foam layer 32 has the advantages of low thermal conductivity, good thermal insulation performance, fire resistance, flame retardancy, non-toxicity, green environmental protection, and sound insulation. At the same time, the fiber glass wool board 33 is an ultra-fine fiber glass wool board, which has the advantages of low thermal conductivity, good thermal insulation performance, and sound absorption and noise reduction.

[0027] The thermal insulation board 34 consists of an outer gas-barrier sealing layer 35 and an inner core material 36. Multiple gas adsorption layers 37 are disposed on the inner side of the gas-barrier sealing layer 35, and a gas-barrier film 38 is disposed on the outer side of the gas-barrier sealing layer 35. The high gas-barrier film 38 possesses excellent fracture resistance and impermeability. The core material 36 is preferably fumed SiO2, ensuring both thermal insulation performance and achieving an ultra-thin design. This not only improves the thermal insulation effect of the board but also significantly extends the service life of the ultra-thin vacuum insulation board. The getter in the gas adsorption layers 37... Using metal-based composite materials (such as magnesium-aluminum alloy particles), through special treatment, residual gas inside the board can be adsorbed, maintaining the stability of the vacuum state, reducing the thermal conductivity of the insulation board, and ensuring its long-term and efficient thermal insulation performance. This improves the thermal insulation performance of the building material. At the same time, by creating a vacuum state inside the board, the insulation board 34 significantly reduces heat transfer caused by air convection, thereby effectively reducing the building's energy consumption. It can also effectively block the three heat transfer modes of heat radiation, heat conduction and heat convection, significantly improving the building's energy efficiency.
