Abstract

Una composición líquida acuosa para el tratamiento de superficies que posee un pH que no se excede de 6.5 y contiene iones de ácido fosfórico, iones deácido fosfórico condensado, un agente oxidante y un polímero soluble en agua comprende, exceptoen los grupos terminales, unidades de polímero expresadaspor la Fórmula (I), en una relación en peso de 0.1 a 30: 0.1 a 10: 0.1 a 10: 0.1 a 20, cuando es puesta en contacto con una superficie de metal aluminíferorápidamente forma sobre ésta un recubrimiento por conversión que posee una buena resistencia a la corrosión y adherencia respecto de capas orgánicasaplicadas subsecuentemente. Este recubrimiento es más difícil de danar que aquellos del arte previo por medio de esfuerzos mecánicos. La formula (I), endonde X1 y X2 independientemente entre sí e independientemente de una unidad del polímero, definiéndose dicha unidad como representada por una modificaciónde la fórmula (I) anterior en donde los corchetes y las n subíndices se omiten, respecto de otra unidad del polímero representan un átomo de hidrógeno, ungrupo alquilo C1-C5,o un grupo hidroxialquilo C1-C5; Y1 y Y2 independientemente entre sí e independientemente respecto de cada unidad del polímero representanun átomo de hidrógeno o una porción Z de acuerdo a una de las siguientes fórmulas generales (II) y (III), en donde R1, R2, R3, R4 y R5 en cada una delas fórmulas (II) y (III) independientemente representan un grupo alquilo C1-C10 o un grupo hidroxialquilo C1-C10; la porción Z puede ser idénticao diferir de cualquier otra porción Z en la molécula de polímero, en tanto se adapte a una de las fórmulas generales (II) y (III); y n representa unentero positivo, que puede ser igual o distinto del valor de n en cualquier otra molécula de polímero.An aqueous liquid surface treatment composition having a pH not exceeding 6.5 and containing phosphoric acid ions, condensed phosphoric acid ions, an oxidizing agent and a water-soluble polymer comprises, except for end groups, polymer units expressed by Formula (I), in a weight ratio of 0.1 to 30: 0.1 to 10: 0.1 to 10: 0.1 to 20, when it is put in contact with an aluminiferous metal surface, it rapidly forms a conversion coating on it that possesses a good corrosion resistance and adhesion to subsequently applied organic layers. This coating is more difficult to damage than those of the prior art by mechanical stress. The formula (I), where X1 and X2 independently of each other and independently of a unit of the polymer, said unit being defined as represented by a modification of formula (I) above where the brackets and the n subscripts are omitted, with respect to another unit of the polymer represent a hydrogen atom, a C1-C5 alkyl group, or a C1-C5 hydroxyalkyl group; Y1 and Y2 independently of each other and independently of each polymer unit represent a hydrogen atom or a Z portion according to one of the following general formulas (II) and (III), where R1, R2, R3, R4 and R5 in each of the formulas (II) and (III) independently represent a C1-C10 alkyl group or a C1-C10 hydroxyalkyl group; the Z portion may be identical or differ from any other Z portion in the polymer molecule, as long as it conforms to one of the general formulas (II) and (III); and n represents a positive integer, which can be equal to or different from the value of n in any other polymer molecule.
