Abstract

L'invention concerne un procédé de préparation d'une couche de nano-revêtement hautement résistante à l'usure et facile à nettoyer, comprenant les étapes suivantes : ajouter de 10 à 15 parties de silicate de lithium, de 20 à 26 parties de silicate de sodium, de 15 à 20 parties de silicate de potassium, de 6 à 12 parties d'un sol de silicium, de 3 à 7 parties d'un sol d'alumine, et de 2 à 5 parties de nano-zircone à 70-80 parties d'eau distillée en séquence, ajouter lentement goutte à goutte une solution mixte de 5 à 9 parties de phosphate d'aluminium, de 7 à 11 parties de triéthanolamine et de 2 à 4 parties de siloxane modifié à la solution, puis filtrer le mélange pour obtenir un nano-revêtement ; laver une surface en acier inoxydable avec un nettoyeur pour acier inoxydable jusqu'à ce que celui-ci soit dans un état hydrophile, rincer l'agent de nettoyage avec de l'eau désionisée, le placer dans une armoire de séchage, et le retirer après séchage de la surface du substrat ; revêtir par pulvérisation le nano-revêtement sur la surface de l'acier inoxydable à l'aide d'un pistolet de pulvérisation à basse pression et à faible débit, puis placer le substrat dans une armoire de séchage à 40 °C-50 °C pour la cuisson, puis le transférer dans une armoire de séchage à 150 °C-170 °C pour la cuisson pendant 1-2 h, et le refroidir à température ambiante, pour obtenir la couche de nano-revêtement hautement résistante à l'usure et facile à nettoyer. La couche de revêtement préparée par le procédé présente une bonne résistance à l'usure et un long vieillissement, et est facile à nettoyer.
