METHOD FOR PRODUCING A SINGLE-CURVED OR A DOUBLE-CURVED COMPOSITE GLASS DISC, IN PARTICULAR FOR MOTOR VEHICLES

摘要

Method of fabricating a single curved or double curved laminated window, especially for motor vehicles, which comprises an inner pane of glass, an outer pane of glass and a plastic film intermediate layer. A screen-printable enamel paint is used which consists of glass flux, at least one ceramic colouring body and an inorganic binder and is mixed with an organic screen printing oil. The printing is applied to the appropriate surface of the pane using the given enamel paint with the aid of the screen printing process. The printing is dried at a temperature at which the screen printing oil is volatile, the screen printing oil evaporating. The two panes with the dried printing are laid one on top of the other, heated to deformation temperature and curved as a pair corresponding to the single or double curvature, the printing being simultaneously stoved. The curved panes of the pair are removed from one another, the plastic film is arranged and the panes of the pair are again laid one on top of the other with the interposition of the plastic film, heated and combined to form the composite glass pane.
