▎ 摘　　要

NOVELTY - Two-component epoxy zinc-rich primer comprises a film-forming liquid and a curing liquid with a mass ratio of 10:1-5. The film-forming liquid 10-20 pts. wt. epoxy resin liquid, 0.5-1 pts. wt. anti-sag agent, 0.5-1 pts. wt. anti-settling agent, 70-80 pts. wt. zinc powder, 2-5 pts. wt. xylene, 1-3 pts. wt. n-butyl alcohol and 0.5-2 pts. wt. anti-settling dispersant. The anti-settling and dispersing agent includes organic bentonite, and the organic bentonite is a bentonite modified by a surfactant, and the surfactant includes quaternary ammonium salt or sodium dodecylbenzenesulfonate. The solidifying liquid includes 60-80 pts. wt. polyamide resin, 20-25 pts. wt. xylene and 5-15 pts. wt. n-butanol. USE - Two-component epoxy zinc-rich primer for steel. ADVANTAGE - The two-component epoxy zinc-rich primer has the advantages of excellent corrosion resistance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a preparation method of a kind of two-component epoxy zinc-rich primer, which involves taking anti-settling dispersant, xylene and n-butanol, stirring and mixing to obtain pre-gel, adding zinc powder to the pre-gel, stirring and mixing, and obtaining a pre-dispersion, stirring and mixing pre-dispersion liquid, epoxy resin liquid, anti-sagging agent and anti-settling agent to prepare film-forming liquid, taking polyamide resin, xylene and n-butanol and stirring and mixing to prepare solidified liquid.
