Abstract

The invention discloses a stain-resistant and flame-retardant building outer wall and a preparation method thereof, and relates to the technical field of new materials. Layered copper-aluminum bimetal hydroxide is prepared, and smoke-abatement effective components exist in a lamellar structure of the layered copper-aluminum bimetal hydroxide, so that carbon formation on the surface of the material and formation of a heat-insulating protective layer are facilitated; the decomposed product is an alkaline porous substance for adsorbing sulfur dioxide in air; and the expanded polystyrene composite material is composed of expandable polystyrene foam beads and has the advantages of being easy and convenient to construct, good in heat preservation performance, resistant to pollution and easy to recycle, the expanded polystyrene composite material and the expanded polystyrene foam beads are matched after being mixed, the wall has better flame retardant performance, and the better heat conduction performance enables the color of the wall to appear more rapidly and accurately. The stain-resistant and flame-retardant building outer wall prepared by the invention has the effects of flame retardance, stain resistance and color change, can perform air purification and self-cleaning in a high-temperature environment with a large amount of sulfur dioxide harmful gas, and has a warning effect through color change.

Description

technical field [0001] The invention relates to the technical field of new materials, in particular to a pollution-resistant and flame-retardant building exterior wall and a preparation method thereof Background technique [0002] Volcanoes are one of the important manifestations of crustal tectonic movement, and play an extremely important role in all stages of the earth's historical evolution, whether it is an active volcano that is still active, or a volcano that has been active in geological history and is now dead; volcano Geomorphic landscapes are the geomorphic relics left by volcanic activities and volcanic activities. Volcanoes are one of the important manifestations of crustal tectonic movements. They play an extremely important role in all stages of the earth's historical evolution. Whether it is an active volcano , or a volcano that has been active in geological history and is now dead. With the development of modern economy, all parts of the country are competi...
