| titleOfInvention | Process for preserving paper |
| abstract | A process is disclosed for preserving paper involving the following steps: (a) a plurality of paper layers in contact with one another at least in regions is simultaneously brought into contact with a preservative fluid containing polycondensates based on one or more hydrolytic polycondensation-capable compounds of elements M of main groups III-V and sub-groups II-IV of the periodic table; in said polycondensates, at least one organic group (G) with at least two carbon atoms and for each carbon atom at least one atom selected from hydrogen or fluorine and without polar substituents is bound, either directly via one of the carbon atoms or via a connecting group A, to at least 0.1 % of the central atoms M; and (b) the paper thus treated with the preservative fluid is dried and/or hardened. In one example of the production of the preservative fluid, 27 g (1.5 mol) of water were stirred into a solution of 55.8 g (0.2 mol) of η-glycidoxypropyltriethoxysilane and 5.1 g (0.01 mol) of1H,1H,2H,2H-perfluoroctyltriethoxysilane. The reaction mixture was then heated for six hours under reflux conditions. 20 g (0.08 Mol) of bisphenol S were added to the by then single-phase solution which was then diluted with 100, 150 or 200 g ethanol. After the bisphenol S had dissolved, 0.8 g (0.001 Mol) of 1-methylimidazole were added as a cross-linking catalyst and the reaction mixture was stirred for 10 minutes. For coating, the solution was poured into a crystallisation dish. |
