Abstract (en)

[origin: WO2022223586A1] The present invention concerns a process for the production of a laminated vacuum insulating glazing assembly (1) that comprises at least one vacuum insulating glazing (2), at least one interunit polymer (3) and at least one functional unit (4); that have been made separately. The functional unit has been produced at a processing pressure (PP) from 5.5 bar to 15.0 bar (5.5 bar ≥ PP ≥15.0 bar).The process for the production of a laminated vacuum insulating glazing assembly (1) that complieswith the High Temperature Test of the norm ISO12543-4:2011; comprises at least the following steps :1) Stacking the vacuum insulating glazing (2), the interunit polymer (3) and the functional unit (4); thereby creating a pre-assembly; 2) Inserting the pre-assembly into a vacuum ring or vacuum bag; 3) Processing the pre-assembly into a laminated VIG assembly by at least the following sub-steps:a. Evacuating to a vacuum of minus 0.1bar to minus 1bar, preferably minus 0.5bar to minus 1bar, within the vacuum ring or vacuum bag, b. Heating the pre-assembly to a temperature ranging from 50°C to 200°C, preferably from 75°C to 175°C, more preferably from 90°C and 150°C.c. Pressurizing the pre-assembly under an overpressure (OP) equal to or lower than 4.5bar (OP ≤ 4.5 bar); and 4) Releasing the evacuation 3)a), the heating 3)b) and the overpressure 3)c).
