| titleOfInvention | Ultra-lightweight newsprint and manufacturing method thereof |
| abstract | (57) [Summary] [PROBLEMS] To provide an ultra-lightweight newsprint excellent in paper strength effect and optical suitability from a raw material mainly composed of high-yield pulp and deinked waste paper pulp. [Constitution] (meth) acrylamide (A), the following formula (In the formula, R 1 and R 2 each independently represent hydrogen or methyl, and HX represents an acid), and a diallylamine-based monomer (B) and a polymerizable monomer having an anionic group (C ) Is a molar ratio of {(B) + (C)} / {(A) + (B) + (C)} = 0.05 to 0.4 constitutional units, and a 15 wt% aqueous solution at 25 ° C A water-soluble copolymer having a field viscosity in the range of 10 poise to 200 poise is added together with a filler to a pulp slurry mainly composed of high-yield pulp and deinked waste paper pulp, and papermaking is carried out to produce an ultralight newspaper. Use as paper. [Effect] Even if it is made extremely lightweight, the strength characteristics and the optical characteristics are well balanced. |
