The coating contains following components in parts by weight: 10 to 20 parts of methyl methacrylate, 15 to 22 parts of butyl acrylate, 3 to 8 parts of styrene acrylic emulsion, 0.5 to 1 part of texanol, 7.6 to 14 parts of hydroxyethyl cellulose, 2.5 to 7 parts of titanium dioxide, 8 to 12 parts of powdered steatile, 3 to 7 parts of wollastonite, 1.2 to 4 parts of potassium laurate, 0.2 to 0.5 part of ammonium persulfate, 0.3 to 1 part of antifoaming agent, 0.5 to 0.8 part of bactericide and 55 to 80 parts of deionized water. The contamination resistance coating for outer walls has the properties of high weatherability, water resistance, contamination resistance, brushing resistance, and weathering resistance.

Description

technical field [0001] The invention relates to an exterior wall paint and a preparation method thereof, in particular to a stain-resistant paint for an exterior wall and a preparation method thereof. Background technique [0002] With the rapid development of social economy, the continuous improvement of people's living standards and the emergence of a large number of high-rise buildings, the requirements for architectural coatings, especially exterior wall coatings, are getting higher and higher. High-performance functional exterior wall coatings have become the focus of current research and development . Exterior wall coatings are exposed outdoors and exposed to wind, sun, and rain for years. They must have good enough water resistance, weather resistance, stain resistance, scrub resistance and weather resistance to ensure good performance. decorative effect and durability. [0003] But the present building exterior wall decoration is easy to be polluted by dust etc. so...
