Abstract

Procédé de préparation de liants cationiques hydrosolubles pour l'application de revêtements par électrodéposition en immersion par réaction de macromolécules portant des groupes oxirannes et ayant un poids moléculaire moyen d'au moins 300 avec des sels d'amines. On fait réagir à une température de 20 à 100 degrés C des carbonates et/ou bicarbonates d'amines aliphatiques et/ou cycloaliphatiques tertiaires et/ou d'alcanolamines avec les groupes oxirannes d'une macromolécule filmogène, à raison de 0,1 à 1 mole d'azote aminé à l'état de carbonate par groupe oxiranne. Le procédé selon l'invention donne des liants stables en solution et qui ne libèrent que de l'anhydride carbonique à l'utilisation.A process for the preparation of water-soluble cationic binders for the application of coatings by immersion electrodeposition by reaction of macromolecules bearing oxirane groups and having an average molecular weight of at least 300 with amine salts. Carbonates and / or bicarbonates of tertiary aliphatic and / or cycloaliphatic amines and / or alkanolamines are reacted at a temperature of 20 to 100 degrees C with the oxirane groups of a film-forming macromolecule, in an amount of 0.1 to 1 mole of amino nitrogen in the carbonate state per oxirane group. The process according to the invention gives binders which are stable in solution and which only release carbon dioxide during use.
