The invention belongs to the field of
coating preparation and especially relates to a railway transit aqueous
epoxy double-component
coating and a preparation method thereof. The
coating includes a component A and a component B, wherein the component A comprises 3-6 parts of a coalescing agent 2,2,4-Trimethyl-1,3-pentanediol monoisobutyrate, 0.5-1 part of an aqueous
epoxy dispersing agent, 0.5-1 part of a chelating-type aqueous
coupling agent, 15-20 parts of
iron oxide red, 15-20 parts of talcum
powder, 4-6 parts of high-molecular-modified
zinc phosphate, 3-4 parts of modified
aluminium triphosphate, 20-25 parts of high-molecular
epoxy resin, 2 parts of an emulsifier containing epoxy groups, 0.1-0.5 parts of an aqueous
wetting agent, 0.1-0.5 parts of an aqueous defoaming agent, 1 part of an anti-
settling agent, 1 part of an anti-flash-
rust agent, 0.3 parts of an aqueous anti-sag agent and 20-30 parts of deionized water; and the component B comprises 80 parts of an aqueous
polyamide epoxy curing agent and 20 parts of deionized water.
