Anti-corrosion self-repair micro-nano capsule for seawater pipeline system of naval ship and preparation method of anti-corrosion self-repair micro-nano capsule

The invention discloses an anti-corrosion self-repair micro-nano capsule for a seawater pipeline system of a naval ship and a preparation method of the anti-corrosion self-repair micro-nano capsule and belongs to the technical field of micro-nano capsule self-repair materials. A wall material of the self-repair micro-nano capsule disclosed by the invention is calcium alginate, a core material of the self-repair micro-nano capsule is tung oil, and the self-repair micro-nano capsule is prepared by using an in-situ polymerization method. The wall material is a nontoxic and pollution-free naturalpolymer material and is wide in source and controllable in cost. The process is simple, reaction conditions are easy to control, and the prepared capsule has the advantages such as high encapsulationrate, benefit for further large-scale production, strong stability and small size, so that influences to mechanical properties of a coating can be reduced, and the repair performance is improved. 用于舰船海水管路系统防腐蚀自修复微纳胶囊及制备方法属微纳胶囊
