桥梁混凝土破损锈蚀露筋修复涂层乳液的制备与研究

选择合适的原料和合成工艺，采用高性能可聚合乳化剂，引入磷酸酯功能单体（EM-39），以衣康酸单丁酯和甲基丙烯酸缩水甘油酯为交联单体，通过活性有机硅氧烷对丙烯酸乳液进行改性，并合成水性丙烯酸防锈乳液。以此乳液为基础，选择防锈剂，制备了水性丙烯酸防锈涂料，其可用于桥梁钢筋混凝土结构破损锈蚀露筋的修复。

Preparation and Study of Coating Emulsion for Repair of Damage,Rusting and Exposed Reinforcing Bars of Concrete in Bridges

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.
