Abstract
Description
Technical Field
[0001] This utility model belongs to the field of building energy-saving doors and windows technology, and particularly relates to a fully encapsulated aluminum-plastic co-extruded composite energy-saving building material structure and a low-energy-consumption sliding door and window. Background Technology
[0002] With the vigorous promotion and widespread application of passive ultra-low energy buildings, the requirements for doors and windows, as key building envelope structures for energy loss, have increased significantly in terms of thermal insulation, airtightness, and structural stability. Existing aluminum-plastic co-extruded doors and windows have the following shortcomings: 1. The bonding stability between the aluminum liner and the plastic layer is insufficient. In extreme climate areas, the plastic layer is prone to expansion, contraction and deformation. Long-term use may lead to detachment, affecting the structural strength. 2. The energy-saving structural design is imperfect. Most of them only use a single thermal break or a simple foam layer, resulting in a high heat transfer coefficient that cannot meet the requirements of the current ultra-low energy consumption standards. 3. Insufficient sealing between the corners and the mullion makes it easy to form energy loss channels, and the energy-saving performance and wind pressure resistance need to be improved; 4. Existing technologies are all made of aluminum alloy, which only improves airtightness from a structural perspective. However, due to the unique structure of side-pressure sliding windows and side-pressure sliding tilt-and-turn windows, as well as the high thermal conductivity of aluminum alloy, the thermal bridge effect is significant, the thermal conductivity coefficient is large, and the energy consumption is high, which greatly reduces the energy-saving effect and fails to meet the national high-efficiency energy-saving standards. Furthermore, due to structural issues, the installation relationship between the sliding tilt-and-turn window sash and the window frame in existing technologies is too small, making the window sash prone to falling off due to external forces and causing accident risks.

Foamed insulation strips 16 are designed in the cavity of the insulation strip, the closed cavity of the profile, and the gaps around the glass to effectively block heat transmission, reduce heat conduction, and improve the energy-saving insulation effect. While coating and laminating the thermal insulation plastic material, an ASA weather-resistant layer can be co-extruded on the outer surface of the thermal insulation plastic material. Traditional processes such as surface spraying and film coating can also be used to increase the weather resistance, durability and anti-aging properties of the plastic material surface.
