Title
(EN) CORROSION-RESISTANT MIRROR
(FR) MIROIR RESISTANT A LA CORROSION
Abstract
(EN) The invention relates to a mirror, including a glass sheet and a silver film applied onto the glass and having, on the back thereof, a protective coating including a dried and cured alkyd paint layer and a dried and cured polyurethane paint layer, the alkyd layer being located between the silver film and the polyurethane layer. The invention also relates to the use thereof for deflecting sunlight to a heat collector. The invention also relates to the method for manufacturing a mirror that includes: depositing a silver film onto a glass sheet by means of a silvering solution; applying an alkyd paint layer having a viscosity of 25 to 110 seconds, measured with a no. 4 Ford cup, onto the silver film; drying and curing the alkyd paint layer; applying a polyurethane paint layer having a viscosity of 25 to 110 seconds, measured with a no. 4 Ford cup, onto the alkyd layer; and drying and curing the polyurethane paint layer.
(FR) L'invention concerne un miroir comprenant une feuille de verre et une couche d'argent appliquée sur le verre et muni en son dos d'un revêtement de protection comprenant une couche de peinture séchée et réticulée du type alkyde et une couche de peinture séchée et réticulée du type polyuréthane, la couche alkyde étant situé entre la couche d'argent et la couche polyuréthane. L'invention concerne également son utilisation pour dévier la lumière solaire vers un collecteur de chaleur. L'invention concerne également le procédé de fabrication d'un miroir comprenant : le dépôt d'une couche d'argent sur une feuille de verre à partir d'une solution d'argenture, puis; l'application du côté de la couche d'argent d'une couche de peinture alkyde de viscosité comprise entre 25 et 110 seconde mesuré à la coupe Ford n°4, puis; séchage et réticulation de la couche de peinture alkyde, puis; l'application du côté de la couche alkyde d'une couche de peinture polyuréthane de viscosité comprise entre 25 et 110 seconde mesuré à la coupe Ford n°4, puis; séchage et réticulation de la couche de peinture polyuréthane.
