Abstract

La presente invención se refiere a un procedimiento para generar superficies antimicrobianas e hidrofílicas sobre substratos de aluminio, que comprende: a) revestir la superficie del substrato con una primera película líquida de una solución acuosa que comprende una sal de metal alcalino o una sal de amonio cuaternario de ácido silícico, la sal teniendo una relación molar de sílice a catión monovalente entre alrededor de 0.5 y aproximadamente 8.5 y, ii) un ácido bórico o una sal del mismo; b) secar mediante calentamiento la película líquida producida en la etapa (a), para producir una primera película sólida sobre la superficie; (c) revestir la película sólida formada en la etapa (b) con una segunda película líquida de una solución que comprende agua, cuando menos 0.01 moles por litro de una sal soluble o hidróxido de un catión con una carga de cuando menos dos unidades; y d) secar mediante calentamiento la película líquida formada en la etapa (c).The present invention relates to a method for generating antimicrobial and hydrophilic surfaces on aluminum substrates, comprising: a) coating the surface of the substrate with a first liquid film of an aqueous solution comprising an alkali metal salt or an ammonium salt quaternary silicic acid, the salt having a silica to monovalent cation molar ratio between about 0.5 and about 8.5 and, ii) a boric acid or a salt thereof; b) drying by heating the liquid film produced in step (a), to produce a first solid film on the surface; (c) coating the solid film formed in step (b) with a second liquid film of a solution comprising water, at least 0.01 mol per liter of a soluble salt or hydroxide of a cation with a charge of at least two units; and d) drying by heating the liquid film formed in step (c).
