该文对3种不同苯乙烯马来酸酐(SMA)季铵盐作为淀粉的表面施胶配方中的一种添加剂的施胶效果进行了研究。即用实验室纸页成型器抄制手抄片,手抄片用2种不同的湿部施胶剂--松香酸和AKD进行内部施胶;然后,这种内部施胶后的纸页分别用含有上述3种不同用量的SMA酰亚胺甲基氯化季铵(imide methyl chloride quaternary)盐改性玉米淀粉进行表面施胶。结果显示,与仅使用淀粉并添加其他种类的SMA施胶相比,SMA酰亚胺甲基氯化季铵盐大大提高了基于淀粉的表面施胶剂的施胶效率;同时,该SMA共聚物对手抄片白度降低的影响微不足道。因此,该新型SMA共聚物可能成为淀粉表面施胶的有效添加剂。
In this paper, the sizing effect of three different SMA maleic acid (SMA) quaternary ammonium salts as an additive in the surface sizing formulation of starch was studied. That is, a manual paper sheet former was used to prepare a hand sheet, which was internally sized with two different wet-end sizing agents, abietic acid and AKD, and then the inner sized sheets were respectively Surface sizing was performed with corn starch modified with SMA imide methyl chloride quaternary salt containing 3 different amounts of the above. The results show that the SMA imide methyl chloride quaternized salt greatly enhances the sizing efficiency of the starch based surface sizing agent compared to using only starch and adding other kinds of SMA sizing; at the same time, the SMA copolymer The impact of reduced copyrighted whiteness on the opponent is insignificant. Therefore, the new SMA copolymer may be an effective additive for starch surface sizing.
