Abstract

In order to prepare a waterborne epoxy zinc-rich primer with excellent corrosion resistance and sagging resistance,a waterborne epoxy zinc-rich primer was prepared using epoxy resin,waterborne epoxy curing agent and relevant accelerator,zinc powder,organic bentonite,fumed SiO2and polyamide wax.The effects of epoxy resin and waterborne epoxy curing agent accelerator on the corrosion resistance of coating were studied,and the orthogonal test with three factors and three levels was used to analyze the influences of different dosages of organic bentonite,fumed SiO2and polyamide wax on the sagging resistance of the waterborne epoxy zinc-rich primer.Results showed that when E51 epoxy resin was used,the curing agent accelerator was 1%,polyamide wax was 0.8%,organic bentonite was 1.5%,and fumed SiO2was 0.4%,all performance index met the requirements for solvent zinc-rich primer.

Key words： waterborne epoxy zinc-rich primer; sagging resistance; corrosion resistance; preparation
