摘　　要：合成纤维混杂成纸时,纤维间因相容性不佳往往引起界面结合强度的不稳定,而应用相容剂是改善合成纤维和浆粕之间相容比例的有效措施.当添加一定的相容剂,在优化热压条件下,可对纸张的力学和电学性能具有较好地提高.以芳纶(PMIA)浆粕/尼龙6(PA6)纤维成纸的机械强度和介电强度为主要研究参数,以马来酸酐为相容剂,优化了成纸的热压温度和热压时间.结果表明,添加反应性相容剂后,纸张的抗张指数提高了56.02%,介电强度提高了110.26%.The interfacial strength between synthetic fibers are often unstable as a result of poor compatibility in composite papers. Application of compatibilizer is an effective method to enhance the compatibility between the synthetic fiber and pulp.It can improve the mechanical strength and electrical strength of paper with the optimization of hot pressing conditions.In this present work,the mechanical strength and dielectric strength of paper with aramid（PMIA） pulp/nylon 6（PA6） fiber was mainly studied,and maleic anhydride was applied as compatibilizer,the hot pressing temperature and time were optimized.The results showed that the tensile strength of the paper increased by 56.02% and the dielectric strength increased by 110.26% at the aid of the reactive compatibilizer.
