The invention discloses a water-based modified acrylic anti-corrosive
coating and a preparation method thereof. The water-based modified acrylic anti-corrosive
coating is prepared from the following raw materials in parts by weight: 250-400 parts of a core-shell structure acrylic
emulsion, 100-250 parts of a
soap-free acrylic
emulsion, 30-150 parts of
pigment, 100-300 parts of filler, 0-50 parts of color paste, 3-10 parts of a dispersing agent, 1-3 parts of a
wetting gent, 1-3 parts of a defoaming agent, 5-15 parts of
propylene glycol, 0.5-5 parts of multifunctional auxiliaries, 1-3 parts of amildew
preservative, 1-3 parts of a
preservative, 10-15 parts of a coalescing agent, 5-10 parts of a
thickening agent, 1-2 parts of a neutralizer, 1-5 parts of a flatting agent, 5-15 parts of a flasherosion inhibitory agent, 150-200 parts of
softened water. The
coating disclosed by the invention is low in VOC content, free from
benzene series, incombustible, low in smell and low in
pollution; the construction can be performed by adopting
brush-coating, roll-coating, airless spraying and like methods, the thick spraying is feasible, the
drying is fast and the use is safe and convenient. The paint film is high in
mechanical strength, strong in
adhesive force and good in
corrosion resistance.
