Abstract

Se describe una composición para el pretratamiento de una superficie de aluminio, que es una solución acuosa compuesta por 2% a 10% de un ácido inorgánico fluorado en peso; 2% a 10% de molibdato, titanato o zirconato de un metal alcalino o alcalinotérreo o amoníaco, opcionalmente en la forma de un derivado fluoroácido en peso y 0,02% a 0,2% de una fuente de agente oxidante con relación al peso total de la composición. Se describe además un método para preparar y aplicar la composición a una superficie de aluminio.Reivindicación 6: Método para preparar la composición como se definió en una cualquiera de las reivindicaciones 1 a 5, caracterizado porque comprende las etapas de: a) preparación de la solución nº 1 que comprende disolver el molibdato, titanato o zirconato de un metal alcalino o alcalinotérreo o amoníaco, opcionalmente en la forma de un derivado fluoroácido; b) preparación de la solución nº 2 que comprende neutralizar el ácido inorgánico fluorado hasta alcanzar el pH 4,5; c) preparación de la solución final que comprende mezclar la solución nº 1 con la solución nº 2 y neutralizar el medio hasta alcanzar el pH en el intervalo de 5,0 a 5,8, agregando finalmente el agente oxidante.A composition for the pretreatment of an aluminum surface is described, which is an aqueous solution composed of 2% to 10% of a fluorinated inorganic acid by weight; 2% to 10% molybdate, titanate or zirconate of an alkali metal or alkaline earth metal or ammonia, optionally in the form of a fluoroacid derivative by weight and 0.02% to 0.2% of a source of oxidizing agent in relation to weight Total composition. A method for preparing and applying the composition to an aluminum surface is further described. Claim 6: Method for preparing the composition as defined in any one of claims 1 to 5, characterized in that it comprises the steps of: a) preparation of the No. 1 solution comprising dissolving the molybdate, titanate or zirconate of an alkali metal or alkaline earth metal or ammonia, optionally in the form of a fluoroacid derivative; b) preparation of solution # 2 which comprises neutralizing fluorinated inorganic acid until pH 4.5 is reached; c) preparation of the final solution comprising mixing solution No. 1 with solution No. 2 and neutralizing the medium until reaching pH in the range of 5.0 to 5.8, finally adding the oxidizing agent.
