Description
Technical Field
The invention belongs to the field of aluminum alloy door and window materials, and particularly relates to a high-temperature-resistant flame-retardant smoke-insulating fireproof aluminum alloy door and window and a preparation method thereof.
Background
Aluminum alloy doors and windows are widely used due to the characteristics of simplicity, attractiveness, transparent lighting, wide visual field, convenience in cleaning and the like. The aluminum alloy doors and windows usually comprise a frame and an inner sash, and are hinged through hinges, and are connected through pulleys and sliding rails, so that the aluminum alloy doors and windows are mainly used for partitions, balcony encapsulation and other scenes.
However, the aluminum alloy doors and windows also have the problem of weak fireproof function. Once a fire occurs, the high-temperature condition can cause the conventional aluminum alloy door and window to be softened, the glass bursts or falls off, the fire and the smoke cannot be isolated from rapidly spreading, and large-scale casualty accidents are easy to occur.
In recent years, with the rapid development of high-temperature-resistant aluminum alloy materials and high-temperature-resistant fireproof glass materials, the above problems have been solved to some extent. However, through analysis of a large number of actual fire cases, it is found that the main cause of massive casualties is not high temperature, but smoke. The existing high-quality fireproof aluminum alloy door and window can only achieve the purposes that the inner sash of the frame is not deformed, the glass is not cracked, but the isolation to smoke is very limited. Generally, aluminum alloy doors and windows need to be provided with soft parting strips between the frame and the inner sash so as to increase the silencing and heat-insulating effects. The division bars are mostly made of high polymer materials, such as rubber materials, and are hardened and embrittled under the high-temperature condition, so that gaps between the frame and the inner fan cannot be sealed. Moreover, such materials themselves generate large amounts of toxic gases and fumes at high temperatures.

In large fire fields, if the temperature of the division bar exceeds 460 ℃, the division bar is gradually embrittled, and the sealing effect is weakened. Even so, the division bar itself does not generate toxic fumes at high temperatures.
