Abstract

L'invention concerne un agent antirouille, une pièce métallique et un procédé de traitement antirouille. L'agent antirouille comprend les constituants suivants, en parties en poids : 50-150 parties d'huile de moteur n° 32, 5-10 parties de sulfonate sodique de pétrole, 2-10 parties d'acide dodécylsuccinique, 1-10 parties d'oléate de triéthanolamine, 1-10 parties de paraffine, 0,1-1 partie de benzotriazole. L'agent antirouille susmentionné peut former une couche de film protecteur polaire dense sur une surface métallique; ledit agent antirouille comprend un inhibiteur de corrosion polymère et peut pénétrer rapidement et profondément dans les pores minuscules d'un métal de manière à obturer de manière étanche les trous d'épingle visibles sur le métal, ce qui permet d'isoler efficacement le métal contre divers facteurs de corrosion qui peuvent provoquer la corrosion du métal; la vapeur d'eau est remplacée, ce qui empêche l'oxydation du matériel par l'air; les milieux acides et basiques sont neutralisés, de manière à empêcher efficacement l'oxydation et la rouille d'une pièce métallique. De plus, après le traitement antirouille, une pièce de métal traitée, telle qu'un produit matériel, devient résistante à un spray salé, à l'humidité, à la chaleur ainsi qu'à l'atmosphère et présente une bonne résistance au trempage dans l'eau salée. L'agent antirouille est particulièrement approprié pour une utilisation dans le traitement antirouille de produits métalliques exportés et transportés par la mer.
