表面施胶淀粉与合成表面施胶剂协同作用的研究

以提高纸张抗水性为目的，应用静态接触角、纸张透气度和Cobb值评价淀粉和合成施胶剂的成膜性与抗水性，探讨了淀粉和合成施胶剂的协同作用。实验结果表明：氧化淀粉B和合成施胶剂d的成膜性最好，其混合使用后能有效的提高纸张抗水性，并控制了生产成本；应用于不同原纸时，对含BCTMP原纸的抗水性提高不明显，却能显著改善白牛皮原纸的抗水性；尤其是应用于高强瓦楞原纸时，完全能够取代浆内施胶，其中Cobb值（60s）降低了85％、耐破指数提高了177％、环压指数提高了91％。

Study on Synergistic Effect of Surface Sizing Starch and Synthesized Surface Sizing Agent

Applying static contact angle,air permeability and Cobb value to evaluate the film forming ability and water resistance of starch and synthetic surface sizing agent,we discussed the synergistic effect of surface sizing starch and synthesized surface sizing agent to improve the water-proof ability of paper and then applied these agents to several different base paper.The results showed that the film forming ability of oxidized starch B and synthesized surface sizing agent d were the best,and their mixture ca...
