Abstract

Tôle d'acier revêtu d'un composite organique et présentant une excellente résistance à la rouille d'origine accidentelle, constituée d'une tôle d'acier galvanisé comportant en surface un revêtement de chromate dans un poids de revêtement donné et également un revêtement organique formé sur le revêtement de chromate, présentant une épaisseur de 0,2-2,0 mu m et contenant les constituants suivants (i) à (iii): (i) une résine de base comprenant une résine époxy ayant au moins un atome d'azote basique et au moins deux groupes primaires hydroxyle à ses extrémités, (ii) un composé polyisocyanate polyfonctionnel possédant au moins trois, de préférence au moins quatre et idéalement au moins six groupes isocyanates dans sa molécule, notamment de préférence un composé polyisocyanate hexafonctionnel constitué d'un dérivé polyfonctionnel d'hexaméthylène diisocyanate, et (iii) un additif antirouille dans un rapport de mélange (rapport en poids de constituants non volatils) définis par l'équation suivante: (résine de base + composé isocyanate polyfonctionnel)/additif antirouille = 90/10 - 40/60. Parmi des exemples d'additif préféré, on peut citer un chromate difficilement soluble et un mélange de silice avec un chromate difficilement soluble (35/5-1/39). Une remarquable résistance à la rouille d'origine accidentelle peut être obtenue grâce à l'effet synergique dû à la composition de résine constituant le revêtement organique et à l'additif antirouille.
