The invention relates to a preparation method and application of a comb-shaped
benzene-horse
polymer water-based dispersant. The comb-shaped
benzene-horse
polymer water-based dispersant is biodegradable and does not contain
alkylphenol; the comb-shaped
benzene-horse
polymer water-based dispersant prepared by the invention has an anionic-nonionic-comb-shaped structure, the molecular structure contains a plurality of
pigment adsorption groups such as aromatic rings,
tertiary carbon
alkyl, carboxyl, hydroxyl, amido and polyether, and the comb-shaped benzene-horse polymer water-based dispersant has excellent
wetting dispersibility, excellent
chemical resistance,
water resistance and
aging resistance, can improve the gloss and tinting strength, can improve the
pigment content, has excellent
system compatibility, low-foam property and excellent low-
viscosity stability, prevents flooding and floating, can be used for preparing resin / resin
system-free high-
solid-content low-
viscosity pigment concentrated
slurry dispersions, such as organic red, yellow and purple pigments,
inorganic pigments and matting
powder, and is particularly suitable for dispersion of
carbon black and
phthalocyanine pigments; the dispersant can also be used for mixing and
grinding organic pigments, anti-
rust pigments and fillers, and is suitable for water-based systems such as water-based color paste, water-based industrial paint, water-based ink, water-based anti-
corrosion and anti-
rust primer and the like.
