Abstract

The invention relates to a process for coating plastics, in which, as primer, an aqueous dispersion is used which contains an aliphatic polyurethane containing reactive carboxyl groups, a polyacrylate, a pigment and optionally a curing agent. The invention comprises using, as coating to be applied to the primer coat, on the one hand an aqueous dispersion which likewise comprises an aliphatic polyurethane containing reactive carboxyl groups, a polyacrylate, optionally a pigment and optionally a curing agent, or which on the other hand, is a mixture of a hydroxyl-containing polymer as binder, an organic solvent, a pigment and a curing agent. Coatings of this type adhere well and do not attack the plastic under the primer coat by penetrating the latter.

Beschreibung : "Verfahren zum Beschichten von Kunststoffen" Description : " Process for coating plastics "

Das Hauptpatent ... (Anmeldung P 33 16 550.5-43) bezieht sich auf ein Verfahren zum Beschichten von Kunststoffen, bei dem man als Grundierungsmittel' eine wässrige Dispersion verwendet, welche ein aliphatisches, reaktionsfähige Carboxylgruppen aufweisendes Polyurethan, ein Polyacrylat, ein Pigment und ggf. einen Härter enthält, wobei das Verhältnis von Polyurethan zu Polyacrylat zwischen 90 : 10 und 10 : 90, insbesondere zwischen 80 : 20 und 20 : 80, insbesondere zwischen 70 : 30 und 30 : 70, insbesondere zwischen 60 : 40 und 40 : 60, liegt.The main patent ... (Application P 33 16 550.5-43) relates to a method for coating plastics in which an aqueous dispersion containing an aliphatic, reactive carboxyl group is used as the primer Polyurethane, a polyacrylate, a pigment and optionally a hardener, the ratio of polyurethane to Polyacrylate between 90:10 and 10:90, in particular between 80:20 and 20:80, in particular between 70:30 and 30:70, in particular between 60:40 and 40:60.

Polyacrylat kann reaktionsfähige Carboxylgruppen aufweisen, aber auch frei von solchen reaktionsfähigen Carboxylgruppen sein (was nicht ausschließt, daß es geringe Mengen herstellungsbedingter Carboxylgruppen aufweist).Polyacrylate can have reactive carboxyl groups, but it can also be free from such reactive carboxyl groups (which does not exclude the fact that it has small amounts of production-related carboxyl groups).

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, einen dazu geeigneten Überzug zu schaffen.The present invention is based on the object of providing a coating that is suitable for this purpose.

Diese Aufgabe wird erfindungsgemäß einerseits dadurch gelöst, daß als auf die Grundierung aufzutragender Überzug eine wässrige Dispersion verwendet wird, welche ein aliphatisches, reaktionsfähige Carboxylgruppen aufweisendes Polyurethan, ein reaktionsfähige Carboxylgruppen aufweisendes oder von solchen Carboxylgruppen freies Polyacrylat, ggf. ein Pigment und ggf. einen Härter enthält, wobei das Verhältnis von Polyurethan zu Polyacrylat zwischen 90 : 10 und 10 : 90, insbesondere zwischen 80 : 20 und 20 : 80, insbesondere zwischen 70 : 30 und 30 : 70, insbesondere zwischen 60 : 40 und 40 : 60, liegt.According to the invention, this object is achieved on the one hand in that an aqueous coating is used as the coating to be applied to the primer Dispersion is used, which is an aliphatic, reactive carboxyl-containing polyurethane, a reactive Polyacrylate containing carboxyl groups or free of such carboxyl groups, optionally a pigment and optionally contains a hardener, the ratio of polyurethane to polyacrylate between 90:10 and 10:90, in particular between 80:20 and 20:80, in particular between 70:30 and 30:70, in particular between 60:40 and 40:60.

Ein solcher Überzug haftet nicht nur gut, er greift ferner den Kunststoff (durch die Grundierung hindurch) nicht an und ist außerdem umweltfreundlich.Such a coating not only adheres well, it also does not attack the plastic (through the primer) and is also environmentally friendly.
