| 中文摘要: |
| 聚氨酯型接枝淀粉表面施胶剂是近年开发的新型表面施胶剂。本研究以聚氨酯预聚体作为抗水性单体合成了性能优良的聚氨酯型接枝淀粉表面施胶剂。聚氨酯预聚体的较佳合成条件为:甲苯二异氰酸酯用量为1,4-丁二醇的15%，反应温度为80℃；施胶剂的较佳合成条件为:预聚体用量为淀粉的10%，单体与淀粉的质量比为2∶1，苯乙烯与丙烯酸丁酯的质量比为1.5∶1。 |
| Abstract: |
| Polyurethane-based grafted starch is a new type of surface sizing agent in recent years. In this paper, polyurethane prepolymer was used as a special water-resisant monomer, polyurethane-based grafted starch agent with good performance was synthesized. The better synthesis conditions of prepolymer were as follows: The amount of toluene di-isocyanate is 15% of 1,4-butanediol, the temperature is 80℃. The optimal synthesis conditions of the sizing agent were as follows: the amount of prepolymer is 10% (on starch), the weight ratio of monomer to starch is 2∶1, the weight ratio of styene to butyl acrylate is 1.5∶1. |
