Description

Technical Field

[0001] The present invention relates to the technical field of energy-saving windows, in particular to an aluminum-coated glass fiber polyurethane energy-saving fire-resistant window, and also to a preparation method of the aluminum-coated glass fiber polyurethane energy-saving fire-resistant window. Background Art

[0002] With the dual demands of new construction and renovation of existing buildings, the market for energy-saving windows is also being cultivated.

[0003] The current mainstream thermal break aluminum alloy windows, plastic steel windows and aluminum clad wood windows in the market all have some problems when it comes to meeting the requirements of energy saving, fire resistance and weather resistance: Thermally insulated aluminum alloy windows form thermal bridges due to the high thermal conductivity of the metal. Although they are reinforced with nylon insulation strips, polyurethane filling, and steel linings, the insulation strips cannot balance the thermal arch and strength requirements. The steel lining is prone to corrosion and reduces thermal insulation, making it difficult to achieve a balance between fire resistance and thermal insulation. Plastic steel windows improve thermal insulation and fire resistance by thickening the cross-section and filling them with fireproof slurry. However, the material is weak in strength and structural rigidity, and is prone to deformation and cracking due to temperature differences. In addition, the fireproof grouting material is difficult to fill the cavity, posing a risk of fire. Aluminum-clad wood windows rely on increasing the thickness of wood profiles to improve thermal insulation, but the external glass moldings make installation difficult and the subsequent maintenance costs are high.

[0004] In summary, while existing energy-saving windows meet the requirements of energy saving, fire resistance and weather resistance at the same time, they have problems such as insufficient strength of insulation materials, poor thermal insulation and fire resistance of supporting structure materials, and difficulty in simultaneously meeting the requirements of installation convenience, structural rigidity and weather resistance. They are unable to meet the increasingly increasing requirements of thermal insulation, fire resistance and weather resistance at the same time. Summary of the Invention

[0036] like Figures 1 to 6 As shown, according to an embodiment of the first aspect of the present invention, an aluminum-clad glass fiber polyurethane energy-saving and fire-resistant window is proposed, including a window frame profile, an aluminum-clad component, a glass system 7, a foam filling 13 and a fireproof board 17.
