| titleOfInvention | Preparation of polyacrylamide having anionic sulfonic acid functional group and its application |
| abstract | The present invention applies polyacrylamide (hereinafter referred to as aromatic polyacrylamide) to which anionic sulfonic acid functional groups including aromatic ring compounds such as polynaphthalene sulfonate or ligno sulfonate is added to increase the bond between pulp fibers during papermaking. This is to increase the strength aptitude of the paper, such as tensile strength, compressive strength, rupture strength and tear strength. At this time, since the pulp fiber is an anion and the aromatic polyacrylamide is an anion, inorganic cationic agents such as alum, PAC (Polyaluminium chloride), polyamine (Dimethylamine epichlorohydrin condensate), PolyDADAMAC, polyvinylamine, By using at least one of organic cationic agents such as cationic polyacrylamide, the pulp fibers may be pre-modified cationic to improve fixability of aromatic polyacrylamide.n n n Polynaphthalene sulfonate, ligno sulfonate, polyacrylamide, strength enhancer |
