摘　　要：以过氧化氢/硫酸亚铁氧化还原体系为引发剂,通过自由基聚合反应在阳离子淀粉分子链上接枝苯乙烯(St)、丙烯酸丁酯(BA),并采用松香对其进行改性,合成了一种淀粉接枝苯丙/松香复合型表面施胶剂。探讨了引发剂、单体、淀粉、交联剂用量对纸张施胶效果的影响。结果表明,其最佳合成工艺条件是:淀粉用量为21.9%,降解过程中过氧化氢用量为3.8%,反应过程中,松香用量为5.8%,硬单体苯乙烯用量为16.3%,软单体丙烯酸丁酯用量为12.5%,引发剂无水硫酸亚铁用量为0.11%,过氧化氢用量为1.9%,交联剂戊二醛的用量为1.4%,合成的松香改性施胶剂的粒径为140nm,应用于瓦楞纸施胶,抗水性能较好,Cobb值可达22.62g/m^2。The grafted starch surface sizing agent was synthesized by free radical polymerization using styrene, butyl acrylate and rosin as the monomers, and hydrogen peroxide/ferrous sulfate as the initiator. Effects of the dosage of initiator, monomer, starch and crosslinking agent on surface sizing were studied. The optimum synthesis conditions are as follows： the dosage of starch 21.9%, the dosage of hydrogen peroxide in the process of pyrolysis 3.8%, the dosage of rosin, styrene, butyl acrylate being 5.8%, 16.3% and 12.5% respectively in the process of reaction. The dosage of hydrogen peroxide and ferrous sulfate were 1.9% and 0.11% respectively, the dosage of glutaraldehyde being 1.4%. Particle size of rosin modified grafted starch was 140 nm. The Cobb value could reach 22.62 g/cm^2 when used in the production process of corrugated paper.
