摘　　要：利用苯乙烯和丙烯酸丁酯对从皮革废弃物中提取的胶原蛋白进行改性,得到一种改性胶原蛋白乳液,并将该乳液单独应用于瓦楞原纸的表面施胶。通过考察施胶后纸张的力学性能和抗水性,确定合成的最佳工艺。实验结果表明:当胶原蛋白与单体的质量比为1∶1.5,引发剂的用量为单体的3.5%,单体中苯乙烯和丙烯酸丁酯的比例为1∶1,反应时间为2h,此时纸张的力学性能和抗水性最好。将合成的改性胶原蛋白乳液与其他胶液复配,并考察施胶效果。The collagen ext racted f rom leather waste was modif ied with styrene and butyl acrylate to get emulsion, which was applied to the surface sizing in corrugated paper. By investigating the mechanica properties and water resistance of paper after sizing, optimization on synthesis process was reached. Experimental results show that when the collagen and monomer mass ratio of 1 to 1.5, the dosage of initiator is3.5% on the monomer, the proportion of the monomers styrene and buty acrylate is 1 to 1, the reaction time was 2 hours, the sizedg paper has the best mechanical properties and water resistance. Then the modifi ed collagen emulsion was sized compound with other emulsion to investigate the sizing effect.
