The invention provides a modified industrial anti-
corrosion aqueous
alkyd coating and a preparation method of same. The
alkyd coating includes, by weight, 35-45 parts of aqueous
alkyd resin, 15-25 parts of aqueous
acrylic resin, 0.2-0.4 parts of a drier, 3-5 parts of a cosolvent, 30-45 parts of
pigment filler, 5-10 parts of an antirust
pigment, 0.1-0.5 parts of an anti-
settling agent, 0.5-1 part of a dispersant, 0.05-0.1 parts of a
defoamer, 0.1-0.5 parts of a flatting agent, 0.3-1 part of an anti-flash-
rust agent and 15-20 parts of water. The modified industrial anti-
corrosion aqueous alkyd
coating is high in
solid content and low in volatile organic compounds (VOCs), is low in environment
pollution, has good
adhesion force, is excellent in recoatability, and has good chemical product resistance,
water resistance and salt
fog resistance. In the invention, through specially designed
epoxy-ester resin and selection of the weather resistant
pigment and antirust pigment, a paint film, formed by the coating, has excellent comprehensive performances, such as fullness,
adhesion force, salt
fog resistance and chemical product resistance; especially, the salt
fog resistance of the coating is greatly higher than that of
epoxy-ester resin in the prior art.
