The invention discloses waterborne bicomponent
epoxy iron red shop primer and a preparation method thereof, and relates to a
coating composition. The waterborne bicomponent
epoxy iron red shop primerprovided by the invention comprises a component A and a component B, wherein the component A is prepared from waterborne
epoxy resin, an iron red
pigment, nano
alumina, a dispersant, a filling material, a waterborne antifoaming agent, a waterborne
preservative, negative
ion distilled water and a waterborne amine curing agent; the component B is prepared from a waterborne epoxy resin
emulsion, a waterborne antifoaming agent, a waterborne
wetting and flatting agent, a waterborne
preservative, a water-soluble active thinner and water. The component A and the component B adopted by the waterbornebicomponent epoxy iron red shop primer provided by the invention are both waterborne products, and are easily mixed; a sufficient curing purpose can be achieved. The waterborne bicomponent epoxy ironred shop primer has higher
impact resistance, cannot generate foaming and stripping phenomena, meanwhile, has advantages of nontoxicity,
flame retarding effect, explosion-proof effect, long application period, high
hardness of film and high
toughness, has uniform color and cluster, and can be used for meeting requirements of safety and
environmental protection.
