The invention discloses an exterior wall paint prepared from the following raw materials in parts by weight: 86-90 parts of waterborne acrylic
emulsion, 17-20 parts of
styrene-acrylic
emulsion, 20-50 parts of
wollastonite powder, 2-3 parts of iso-
octyl acrylate, 1-2 parts of
potassium borate, 0.4-1 part of
ethylene glycol dimethacrylate, 3-4 parts of
tungsten boride, 1-2 parts of
sodium dodecyl sulfate, 0.6-1 part of
dibenzoyl peroxide, 3-4 parts of absolute ethyl
alcohol, 0.8-1 part of gamma-aminopropyltriethoxysilane, 0.1-0.2 part of polyoxyethylene polyoxypropylene
ether, 3-5 parts of coalescing agent and 10-20 parts of deionized water. The paint produced by the invention is low in
raw material loss, less in gel generation, simple in process, firm in paint film, good in glossiness, strong in
impact force resistance, not easy to crack, soft in texture, strong in decoration, high in weather and scrubbing resistance, strong in
adhesive force, long in service life, free of special smell,
heavy metals such as mercury, lead and the like and
formaldehyde volatiles, and capable of meeting the technical requirement of an environment-friendly paint; and the added coalescing agent has very high stability, efficient adhesiveness and film forming property, so that the density of the paint film is increased, the film forming quality is improved, and a film layer has the advantages of strong
adhesive force, no hole and
rift, densification, uniformity and the like.
