Title
(EN) Stimulus-responsive self-repair anticorrosive coating material and preparation method
(ZH) 一种刺激响应型自修复防腐涂层材料和制备方法
Abstract
(EN)
The invention discloses a stimulus-responsive self-repair anticorrosive coating material and a preparation method. The coating material comprises a CuO microcapsule and a coating matrix. The CuO microcapsule comprises a capsule core and a capsule core carrier, the capsule core is a corrosion inhibitor, and the capsule core carrier is porous CuO; and the surface of the CuO microcapsule is coated byan anionic polyelectrolyte layer and a cationic polyelectrolyte layer alternately. The invention successfully constructs the anticorrosive coating material with ph responsiveness and self-repair dualefficacy. The porous CuO can improve the loading rate and encapsulation rate of the capsule core substance; at the same time, the anionic polyelectrolyte can be adsorbed on the surface by means of layer-by-layer self-assembly, under the action of Coulomb force, then cationic polyelectrolyte can be adsorbed on the surface, thus improving the dispersibility of the microcapsule in the coating, solving the agglomeration problem of the porous substance CuO, and at the same time improving the bonding performance of the capsule core carrier and the coating matrix, and the anticorrosion performance of the coating material can be further improved.

本发明公开了一种刺激响应型自修复防腐涂层材料和制备方法。该涂层材料包括CuO微胶囊和涂层基体,所述CuO微胶囊包括囊芯和囊芯载体,所述囊芯为缓蚀剂,所述囊芯载体为多孔CuO;所述CuO微胶囊的表面为交替包覆的阴离子聚电解质层和阳离子聚电解质层。本发明成功构建了具有pH响应和自修复双重功效的防腐涂层材料。多孔CuO可以提高囊芯物质的装载率和封装率;同时,阴离子聚电解质可通过层层自组装的方法吸附在其表面,在库仑力的作用下,再吸附阳离子聚电解质在其表面,改善了微胶囊在涂层中的分散性,解决了多孔物质CuO的团聚问题,同时提高了囊芯载体与涂层基体的结合性能,使涂层材料的防腐性能得到进一步提高。
