Abstract

Epoxy-polyurethane coatings for the walls of acid treatment workshops were prepared by using macromolecular bisphenol A epoxy resin as the main resin with the addition of color filler and auxiliary agents,HDI trimer as the hardener.The effects of epoxy resin equivalent,NCO/OH value,the amounts and types of catalyst,polymer inhibitor and organobentonite on the properties of coating films were studied.The epoxy-polyurethane coatings prepared for the walls of acid treatment workshops has good mechanical properties and excellent chemical resistance.

Key words
