Description

Technical Field

[0001] This invention relates to the field of door and window insulation technology, and in particular to an ultra-energy-saving thermal insulation profile, its preparation method and door and window installation structure. Background Technology

[0002] Thermally broken aluminum profiles, also known as insulated aluminum alloy profiles, thermally broken aluminum alloy profiles, thermally broken profiles, or thermally broken aluminum-plastic composite profiles, offer superior performance compared to ordinary aluminum alloy profiles. Aluminum alloy, being a metal, conducts heat quickly. Therefore, when there's a significant temperature difference between indoors and outdoors, the aluminum alloy can act as a "bridge" for heat transfer. Windows and doors made from such materials often have poor insulation. Thermally broken aluminum profiles, however, break the aluminum alloy in the middle and connect the broken sections with a rigid plastic material. Plastic conducts heat much less effectively than metal, preventing heat from easily passing through the entire material, thus improving its insulation performance. This is what is meant by "thermally broken aluminum." For example... Figure 1 As shown, this is a common type of thermally insulated aluminum-plastic profile for building doors and windows. The thermally broken aluminum profile 902 is separated by nylon P66901, and the nylon P66901 is used for installation. The connection between the nylon P66901 and the thermally broken aluminum profile 902 has low strength, resulting in gaps at the joint. The heat transfer coefficient (UF value) of the window frame is greater than 1.0 W / m²K, indicating poor thermal insulation performance. The presence of these gaps also negatively impacts sound insulation and noise reduction performance.

[0003] Therefore, in order to address the above problems, the present invention urgently needs to provide an ultra-energy-saving thermal insulation profile, its preparation method, and a door and window installation structure. Summary of the Invention

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0023] like Figure 2 As shown in the figure, this embodiment provides a method for preparing a high-efficiency energy-saving thermal insulation profile, comprising the following steps: S1) Connect the first inner aluminum 1 and the first outer aluminum 2 through the first polyurethane core material 3 to obtain a fixed frame; S2) Connect the second inner aluminum 4 and the second outer aluminum 5 through the second polyurethane core material 6 to obtain an openable fan; S3) The fixed frame and the operable sash are hinged together by a hinge; the connection between the fixed frame and the operable sash is also sealed by a first sealing element to obtain an ultra-energy-saving heat-insulating profile. The thickness of the first polyurethane core material 3 and the second polyurethane core material 6 is greater than 60 mm; the thickness of the first inner aluminum 1 is greater than the thickness of the first outer aluminum 2; and the thickness of the second inner aluminum 4 is greater than the thickness of the second outer aluminum 5.

[0024] The method for preparing the ultra-energy-saving thermal insulation profile proposed in this invention involves connecting a first inner aluminum 1 and a first outer aluminum 2 with a first polyurethane core material 3 to form a fixed frame, and connecting a second inner aluminum 4 and a second outer aluminum 5 with a second polyurethane core material 6 to form an operable sash. The fixed frame and the operable sash are then connected by connectors. The thickness of both the first and second polyurethane core materials 3 and 6 is limited to greater than 60mm; the thickness of the first inner aluminum 1 is greater than the thickness of the first outer aluminum 2; and the thickness of the second inner aluminum 4 is greater than the thickness of the second outer aluminum 5, ensuring that the thickness of the polyurethane core material is greater than 60mm. This compression of the overall thickness of the first and second outer aluminum reduces heat conduction, resulting in a window frame heat transfer coefficient (UF value) of less than 0.8 W / m²K, meeting the requirements for ultra-energy-saving profiles. Furthermore, the reduction in the overall thickness of the first and second outer aluminum reduces the amount of aluminum used, lowering manufacturing costs. Additionally, the reduced overall thickness of the ultra-energy-saving thermal insulation profile reduces the requirements for building wall thickness, making it more versatile. The resulting ultra-energy-saving and heat-insulating profiles are high in strength and durable, meeting the needs of long-term window use.

All these dimensions achieve a window frame heat transfer coefficient (UF value) below 0.8 W / m²K, resulting in good thermal insulation performance. With a window frame heat transfer coefficient (UF value) below 0.8 W / m²K, the overall thickness of the ultra-energy-saving thermal insulation profile can be below 95mm, reducing the requirements for building wall thickness and lowering construction costs.
