The invention relates to a method for producing
paper, mat, laminate or similar material web using a
binder feeding mechanism and by subsequent hardening.
In this method, a water-dilutable acrylate in the form
of a binder is fed to the material web at the binder
feeding mechanism. The material web is then hardened
by an electron beam, after the water content has been
evaporated off. After feeding the binder, or after the
impregnation process, the material web containing the
noncrosslinked acrylate is dried and the water is
evaporated from the binder, preferably an emulsion.
The material web is then printed and crosslinkage or
polymerization begun. After printing, a varnish is
applied that is capable of being hardened by an
electron-beam. The material or paper web can be
pressure-impregnated with the acrylate.
L'invention concerne un procédé pour produire du papier, non-tissé, stratifié ou une bande de matériau similaire (16), au moyen d'un système d'alimentation en liant (12), et par un durcissement ultérieur, notamment d'une bande de matériau (16) résistant à la fissuration, traité ultérieurement au moyen d'un processus de mise en peinture. Selon ce procédé, un acrylate diluable dans l'eau est acheminé sous forme de liant à la bande de matériau, au niveau du système d'alimentation en liant (12). La bande de matériau ainsi traitée est durcie, après évaporation de la proportion d'eau, au moyen d'un faisceau électronique. Selon l'invention, après l'acheminement du liant ou après l'opération d'imprégnation, la bande de matériau (16) contenant l'acrylate non réticulé est séchée, puis l'eau est évaporée du liant, de préférence d'une émulsion. La bande de matériau (16) est imprimée, puis la réticulation ou la polymérisation est déclenchée. Après l'impression, une peinture durcissable au faisceau électronique est appliquée, la bande de matériau ou de papier pouvant être imprégnée avec l'acrylate par pression. Le liant présent dans les restes de papier non réticulés ou en excès après l'opération d'imprégnation, notamment l'émulsion d'acrylate, est de préférence réintroduit (18, 20, 28, 32) dans le système d'alimentation en liant (12).
