Title
(EN) NON-TOXIC WATER-BASED FRIT PASTE, AND ASSEMBLY INCORPORATING THE SAME
(FR) PÂTE DE FRITTAGE NON TOXIQUE À BASE D'EAU ET ENSEMBLE QUI LA CONTIENT
Abstract
(EN)
Certain example embodiments of this invention relate to a frit paste for use in assemblies (e.g., a vacuum insulated glass unit or a plasma display panel), and methods of making the same. Frit powder, binder material, and a water-based solvent are mixed together to form an intermediate mixture. The frit powder is substantially lead free, and the water-based solvent is provided at a first temperature. Additional water-based solvent is added to the intermediate mixture to form a frit paste. The additional water-based solvent is provided at a second temperature, with the second temperature being lower than the first temperature. The binder material is provided at a concentration of 0.001 %-20% by weight with respect to the frit paste or the frit paste absent the frit powder. The frit paste has a bulk viscosity of 2,000-200,000 cps.
(FR)
Certains exemples de modes de réalisation de la présente invention concernent une pâte de frittage destinée à être utilisée dans des ensembles (par exemple une unité de vitrage isolé sous vide ou un panneau d'affichage à plasma) et des procédés pour la fabriquer. Une poudre de frittage, un liant et un solvant à base d'eau sont mélangés pour former un mélange intermédiaire. La poudre de frittage est essentiellement exempte de plomb et le solvant à base d'eau est obtenu à une première température. Un supplément de solvant à base d'eau est ajouté au mélange intermédiaire pour former une pâte de frittage. Le solvant supplémentaire à base d'eau est obtenu à une deuxième température, la deuxième température étant plus basse que la première température. Le liant est obtenu à une concentration de 0.001 à 20 % en poids par rapport à la pâte de frittage ou à la pâte de frittage sans poudre de frittage. La pâte de frittage présente une viscosité volumique de 2 000 à 200 000 cps.
