Abstract

Disclosed is a polyurea coating acting against ocean engineering corrosion. The polyurea coating comprises a component A and a component B, wherein the component A comprises a polyisocyanate and a polycarbonate polyol, and the component B comprises an amine-terminated polyether, an amino chain extender, a modified nano titanium dioxide, a nanometer zinc oxide, a hydroxyamino carboxylic acid compound, an anti-foulant, an anti-rust pigment and an anti-settling agent. The raw materials for preparing the modified nano titanium dioxide comprises nano titanium dioxide, a surfactant, a silane coupling agent, silver nitrate and copper sulfate. The polyurea coating has a strong seawater and salt fog resistance, can resist microbial adhesion, and is suitable for acting against marine engineering corrosion.
