/ PROCESS FOR THE PRODUCTION OF SIZED AND/OR WET-STRENGTH PAPERS PAPERBOARDS AND CARDBOARDS

摘要

The present invention relates to a process for the production of sized and / or wetted paper, paperboard or cardboard, comprising the steps of mixing an aqueous radiation curable dispersion containing at least one polymer and water, characterized by containing cationic groups, / RTI and / or chemical pulp, the mixture is sieved, squeezed, thermally dried and radiation cured, and the dispersion is applied on the basis of the non-aqueous material content with respect to the solid content of the wood pulp and / Is used in an amount of 0.001 to 10% by weight; Paper, paperboard and cardboard manufactured by this method; And a waterborne radiation curable dispersion containing at least one polymer characterized by containing suspended wood pulp and / or chemical pulp, and cationic groups.
