制备出几种淀粉衍生物表面施胶液,并对比了施胶后瓦楞纸的环压强度以及耐折度这两项指标。实验结果表明利用N-羟甲基丙烯酰胺改性淀粉施胶,成纸环压指数最好,可达2.24N·m2·g-1;利用六次甲基四胺改性淀粉,成纸耐折度最好,可达22次。
Several kinds of starch derivatives surface sizing solution were prepared, and the two indexes of crushing strength and folding resistance of corrugated paper after sizing were compared. Experimental results show that the use of N-methylol acrylamide modified starch sizing, the paper ring pressure index the best, up to 2.24N · m2 · g-1; hexamethylenetetramine-modified starch, paper resistance Fraction of the best, up to 22 times.
