| 摘 要： | 以丙烯腈改性淀粉为分散剂,采用自由基聚合法在淀粉分子链上接枝苯乙烯(St)、丙烯酸丁酯(BA)、甲基丙烯酸二甲基氨基乙酯(DM)和丙烯酰胺(AM)等共聚单体,合成出一种新型的阳离子型淀粉接枝苯丙乳液施胶剂。探讨了K2S2O8/NaHSO3氧化还原型引发剂、共聚单体等对施胶剂施胶效果的影响。结果表明:当w(DM)=2%、w(AM)=0.3%、m(改性淀粉)∶m(单体)=1.0∶1.5、m(St)∶m(BA)=2.3∶1.0、引发剂中m(K2S2O8)∶m(NaHSO3)=1.0∶1.0且氧化剂w(K2S2O8)=0.10%时,施胶剂的施胶效果最佳,并且优于传统苯丙乳液施胶剂。

| Abstract: | With starch modified by acrylonitrile(AN) as dispersant,the starch molecular chain grafted by some comonomers such as styrene(St),butyl acrylate(BA),dimethyl amino ethyl methacrylate(DM) and acrylamide(AM) via free radical polymerization,then a new type cationic starch grafted by styrene-acrylate emulsion as sizing agent was synthesized.The influences of some factors such as K2S2O8 /NaHSO3 redox initiator,comonomer were discussed on sizing results of sizing agent.The results showed that the sizing result of... |
