Abstract

The invention belongs to a building exterior wall coating with high contamination resistance and a preparation method thereof, and relates to the field of coating production. The coating prepared through the method comprises polymer emulsion, titanium dioxide nanometer powder, silicon dioxide nanometer powder, filler, a low-surface-tension hydrophobic agent, a coalescing agent, a dispersing agent, a defoaming agent, a wetting agent and water. The waterproofness, contamination resistance and weather resistance of the building exterior wall coating produced through the method can be improved.

Description

technical field [0001] The invention relates to the field of paint production, in particular to the production of building exterior wall paint. Background technique [0002] Bricks, mosaics, glass curtain walls and coatings are often used for beautification and decoration on the exterior walls of buildings. Because paint is easy to be contaminated with oil in the air and easy to leave water stains after being eroded by wind and rain, which greatly affects the aesthetic feeling of buildings, facing bricks, mosaics and glass curtain walls occupy the main market of existing building exterior wall decorations . However, the use of exterior wall decorations such as facing bricks, mosaics, and glass curtain walls in high-rise buildings will cause potential safety hazards. The market has an urgent demand for coatings with waterproof and oil-proof properties. [0003] CN 102732079 A (2012.10.17) discloses a preparation method of exterior wall paint, and the stain resistance of the...
