Abstract: | With monobutyl itaconate and glycidyl methacrylate as linking monomers, this paper modifies acrylic emulsion via active organo-siloxane and synthesizes water-based acrylic anti-rust emulsion by selecting appropriate raw materials and synthetic processes, adopting high-performance polymerizable emulsifier and introducing functional phosphate monomers ( EM-39 ) . With this emulsion as basis, the paper selects antirust agents to prepare waster-based acrylic anti-rust coating, which can be used to repair damage, rusting and exposed reinforcing bars of concrete structures in bridges. |

Keywords: | modified acrylic anti-rust emulsion water-based acrylic anti-rust coating damage and exposed reinforcing bars of concrete repair study |
