Title (EN) METHOD FOR PRODUCING LAMINATED GLAZING WITHOUT ENAMEL STICKING TO THE BACK-GLASS
(FR) PROCÉDÉ DE FABRICATION D'UN VITRAGE FEUILLETÉ EVITANT LE COLLAGE DE L'EMAIL SUR LE CONTRE-VERRE
Abstract:
(EN) The invention relates to a method for producing a laminated glazing comprising at least one first and one second glass sheet, in which the face of the first glass sheet intended to be oriented towards the second is printed with a liquid enamel which is dried at a temperature not exceeding 400°C, then the first and the second glass sheets are bent together in contact with each other in their relative target position in the laminated glazing, by heating to a softening temperature of the glass, characterised in that the liquid enamel is an aqueous silicate paint comprising a refractory powder of pigments and a binding powder containing silicates, in the absence of glass frit, and in that the mass ratio of the pigments to the silicates is higher than 1.
(FR) La présente invention a trait à un procédé de fabrication d'un vitrage feuilleté comprenant au moins une première et une seconde feuilles de verre, dans lequel la face de la première feuille de verre destinée à être orientée vers la seconde est imprimée avec un émail liquide qui est séché à une température n'excédant pas 400 °C, puis la première et la seconde feuilles de verre sont bombées ensemble en contact l'une avec l'autre dans leur position relative de destination dans le vitrage feuilleté, par chauffage à une température de ramollissement du verre, caractérisé en ce que l'émail liquide est une peinture aqueuse au silicate comprenant une poudre réfractaire de pigments et une poudre de liant aux silicates, en l'absence de fritte de verre, et en ce que le rapport en masse des pigments sur les silicates est supérieur à 1.
