Abstract:

以4,4'-二氨基二苯乙烯-2,2'-二磺酸(DSD酸)为原料,三聚氯氰为交联单体,将自由基捕获剂2,2',6,6'-四甲基哌啶胺(4-氨基哌啶)与二苯乙烯荧光增白剂引入同一分子中,经过亲核取代等设计出既含有荧光增白基团又具备自由基捕获功能的双三嗪氨基二苯乙烯荧光增白型的新型返黄抑制剂。采用红外和核磁光谱、紫外光谱、荧光光谱分析方法对其结构及其光学性质进行了初步研究,并通过紫外线加速老化实验考察了目标产物对化机浆纸张的返黄抑制效果。实验结果表明:合成的目标产物在涂布中的最佳浓度用量为0.8%,经过48h光老化处理后,合成的产物光抑制效果更好,更适合作光诱导返黄抑制剂,与单独使用荧光增白剂和受阻胺类返黄抑制剂相比,老化后纸张的白度分别少下降了3.38%ISO和6.49%ISO。
