The invention relates to an anti-
corrosion and super-weatherability
powder coating. The
coating comprises a base paint and a face paint, wherein the base paint is an anti-
corrosion epoxide powder coating and comprises the following components in percentage by
mass: 53 to 62 percent of
epoxy resin, 3 to 12 percent of curing agent, 5 to 15 percent of
pigment, 15 to 25 percent of filler and 2 to 8 percent of auxiliary agent; and the face paint is a super-weatherability
polyester powder coating and comprises the following components in percentage by
mass: 58.5 to 62.4 percent of carboxyl-terminated
polyester resin, 2.6 to 6.5 percent of curing agent, 10 to 20 percent of
pigment, 10 to 20 percent of filler and 2 to 6 percent of auxiliary agent. The anti-
corrosion and super-weatherability
powder coating is a
powder coating with super corrosion resistance and super
adverse weather condition resistance, such as super
ultraviolet ray resistance and the like. The
adhesive force between the base paint and the face paint is good; the coating efficiency is high; and the
powder coating causes no
pollution to environment. The invention also provides a preparation method of the powder coating.
