摘　　要：采用聚乙烯醇(PVA)、水解胶原蛋白(HC)、苯乙烯(ST)和丙烯酸丁酯(BA)等四种单体共聚合成了一种造纸用表面施胶剂.通过单因素优化实验,以合成施胶剂对瓦楞原纸施胶后性能作为参考指标,确定了施胶剂的最佳合成条件.结果表明:当水解胶原蛋白与单体的质量比为1∶1.25(4∶5)、引发剂的用量为单体的4%(质量比)、单体中的丙烯酸丁酯和苯乙烯的比例为1:3、反应时间为3.5小时等时,合成施胶剂对纸张性能的提高最为明显.将合成的四元共聚施胶剂与其它胶液复配施胶,其结果显示:当四元共聚施胶剂单独施胶,以及其与淀粉复配后施胶时,纸张的抗张指数分别增大25.51%和25.45%;四元共聚施胶剂单独施胶以及其与淀粉复配施胶等对纸张的环压指数分别提高54.53%和54.33%,较淀粉与苯丙乳液复配施胶的效果(62.78%)稍弱;四元共聚施胶剂与苯丙乳液复配施胶、淀粉与苯丙复配施胶等对纸张的抗水性分别提高74.42%和68.61%.In this paper,a kind of surface sizing agent for paper was copolymerized by using polyvinyl alcohol（PVA）,hydrolyzed collagen（HC）,styrene（ST）and butyl acrylate（BA）.Make the performance of sized corrugated paper as the reference index,the optimal synthesis conditions of synthetic sizing agent were determined by single factor optimization experiment.The result shows that when the mass ratio of hydrolyzed collagen and monomer was 1∶1.25,the dosage of initiator was 4% of the monomer,the mass ratio of BA and ST was 1∶3,the reaction time was 3.5hours,the best performance improvement of the sized paper was obtained.Surface sizing on paper was concluded with the synthetic quaternary sizing agent and other sizing agent,it indicates that sizing with quaternary sizing agent,and sizing with quaternary sizing agent and starch,the tensile index of paper respectively increase 25.51%and 25.45%;the paper′s ring crush index respectively increase 54.53%and 54.33%,but the effect is still weaker than 62.78% which sizing with starch and propyl benzene latex;sizing with quaternary sizing agent and propyl benzene latex or starch and propyl benzene latex can increase the water-resistance 74.42% and 68.61%respectively.
