Title (EN) ANTI-CORROSIVE COATING WITH SELF-REPAIRING ABILITY, PREPARATION METHOD THEREFOR, AND APPLICATION THEREOF
(FR) REVÊTEMENT ANTI-CORROSION PRÉSENTANT UNE CAPACITÉ D'AUTO-RÉPARATION, SON PROCÉDÉ DE PRÉPARATION ET SON APPLICATION
(ZH) 具备自修复能力的防腐涂层及其制备方法和应用
Abstract:
(EN) An anti-corrosive coating with self-repairing ability, comprising an anti-corrosive inner layer and a self-repairing surface layer. The material of the self-repairing surface layer mainly consists of polyaniline coated sodium alginate microcapsules and an epoxy resin, and the material of the anti-corrosive inner layer mainly consists of graphene oxide modified with boric acid and/or borax. A preparation method therefor comprises: preparing a material of an anti-corrosive inner layer, and coating the material of the anti-corrosive inner layer on a substrate to form the anti-corrosive inner layer; preparing a material of a self-repairing surface layer, and coating the material of the self-repairing surface layer on the anti-corrosive inner layer, to form the self-repairing surface layer; and forming an anti-corrosive coating. The anti-corrosive coating can prevent water pipelines from being corroded by liquid environments, and has a rapid self-repairing ability.
(FR) L'invention concerne un revêtement anti-corrosion présentant une capacité d'auto-réparation, comprenant une couche interne anti-corrosion et une couche de surface auto-réparatrice. Le matériau de la couche de surface auto-réparatrice est principalement constitué de microcapsules d'alginate de sodium enrobées de polyaniline et d'une résine époxy, et le matériau de la couche interne anti-corrosion est principalement constitué d'oxyde de graphène modifié avec de l'acide borique et/ou du borax. Un procédé de préparation associé comprend : la préparation d'un matériau d'une couche interne anti-corrosion, et le revêtement du matériau de la couche interne anti-corrosion sur un substrat pour former la couche interne anti-corrosion ; la préparation d'un matériau d'une couche de surface auto-réparatrice, et le revêtement du matériau de la couche de surface auto-réparatrice sur la couche interne anti-corrosion, pour former la couche de surface auto-réparatrice ; et la formation d'un revêtement anti-corrosion. Le revêtement anti-corrosion peut empêcher des canalisations d'eau d'être corrodées par des environnements liquides, et présente une capacité d'auto-réparation rapide.
(ZH) 一种具备自修复能力的防腐涂层,包括防腐内层和自修复面层,自修复面层的材料主要由聚苯胺包覆海藻酸钠微胶囊和环氧树脂组成,防腐内层的材料主要由硼酸和/或硼砂修饰过的氧化石墨烯组成。其制备方法包括:制备防腐内层材料,将防腐内层材料涂布在基体上,形成防腐内层;制备自修复面层的材料,将自修复面层的材料涂布在防腐内层上,形成自修复面层;形成防腐涂层。该防腐涂层能够防止输水管道被液体环境腐蚀,同时具有快速的自修复能力。
