摘　　要：以含氟丙烯酸酯为主要单体制备了纸张防油剂,利用红外光谱和激光粒度仪对防油剂进行表征。研究了防油剂、阳离子淀粉、聚乙烯醇对表面施胶纸张防油性能的影响,并对纸张进行SEM电镜分析。采用O il K it Test-TAPPI 557国际通用测试法检测表明,当防油剂用量0.6%、阳离子淀粉用量1.0%、聚乙烯醇用量0.8%时,纸张防油等级可达9级。纸张表面强度、抗张强度、耐折度和耐破指数分别提高45.2%、9.3%、22.2%和7.8%。The oil-proof agent for paper was synthesized by using fluoroacrylate as the main monomer, and it was characterized by FT-IR and laser diffraction particle size analyzer. The effect of oil-proof agent dosage, the cationic starch dosage and PVA dosage on oil-proof properties of the surface sized paper were studied, the physical performance of the paper was also discussed. The paper was characterized by SEM and using Oil Kit Test-TAPPI557, the results showed that the oil repellent grade was 9 when the oil-proof agent dosage is 0.6%, the cationic starch dosage is 1.0%, and PVA dosage is 0.8%. The paper surface strength, tensile strength, folding endurance and burst index were increased by 45.2% ,9.3% ,22.2% and 7.8% respectively.
