| Abstract: |
| The emulsion polymerization method with tung oil and inhibitor serving as the capsule core is used to synthetize the self-healing microcapsules. And a certain amount of self-healing microcapsules are added into the anticorrosive coating in order to improve the self-healing ability of coating and to enhance the anticorrosion performance of carbon steels. Analysis results of SEM and thermogravimetry show that self-healing microcapsules possess a diameter of ~3 μm and that the core coverage percent reaches 48%. Experimental results of neutral salt spray tests and immersion tests show that the organic coating presents an optimal anticorrosive ability accompanying with the best self-healing action when the content of microcapsules in the coating reaches 10% and the ratio of tung oil and inhibitor in the core is 5∶1. The organic anticorrosive coating with two- component microcapsules has the satisfactory self-healing activity, and has long-term protective effects on the metal materials. |
