摘要
本文主要利用松香和TDI合成聚氨酯预聚体,利用甲基二乙醇胺扩链,最后用亚硫酸氢钠作封闭剂,最后乳化得到阳离子松香型聚氨酯。同时,将此种施胶剂应用于造纸湿部中,研究了扩链剂用量,pH及APAM用量对聚氨酯施胶性能的影响。实验表明,此种施胶剂在中碱性环境中施胶效果较好。
In this paper, rosin and TDI polyurethane was used for prepolymer, the use of methyl diethanolamine as chain extender, with the NaItSO3 for blocking compound to cationic emulsion Rosin polyurethane. At the same time, such sizing agent was used in the Department of wet, the experiment showed that such Size, Sizing was effective.
