The invention discloses a water-based
fluorine-modified
polyester can-making
coating and a preparation method thereof, relates to the technical field of
industrial water-based coatings, and particularly relates to a water-based
fluorine-modified
polyester can-making
coating and a preparation method thereof. Comprising the following raw materials in parts by weight: 20-50 parts of modified
fluorocarbon emulsion, 10-30 parts of waterborne
polyester resin, 10-20 parts of deionized water, 0.2-1 part of a dispersing agent, 0.2-0.5 part of a defoaming agent, 20-40 parts of
pigment filler, 0.5-2 parts of a
thickening agent, 0.5-2 parts of a coalescing agent, 0.2-0.8 part of a
wetting agent and 30-80 parts of a curing agent. According to the water-based paint prepared by the preparation method disclosed by the invention, the
ultraviolet crosslinking elastic
emulsion is introduced into the single
fluorocarbon emulsion so as to modify the
fluorocarbon emulsion, and then the fluorocarbon emulsion is mixed with the water-based
polyester resin, so that the water-based
fluorine-modified polyester can-making paint is prepared; the phenomenon that a single water-based
fluorocarbon coating is poor in
weather resistance, gloss retention and
hardness compared with a
solvent-type
fluorocarbon coating in the using process can be effectively reduced, the service life of the
coating is prolonged, and the using effect of the coating is improved.
