摘　　要：为研究膨胀型阻燃剂的合成及发泡剂的制备,以及在聚己二酰己二胺中的应用,采用碳化剂季戊四醇、碳化促进剂多聚磷酸铵与发泡剂三聚氰胺等来制备膨胀型阻燃体系,并按不同配比与聚己二酰己二胺进行复配,测定该塑料的阻燃性能和力学性能。实验结果表明:阻燃剂用量对塑料的强度和阻燃性能产生了较大的影响,氧指数随阻燃剂的增加而增大,当阻燃剂达到30%以上时,氧指数增大的趋势减弱;平均燃烧时间和烟密度则随着阻燃剂用量的增加而减小。In order to study the synthesis of intumescent flame retardant and the preparation of foaming agent,as well as its application in polyadipylhexanediamine,the carbonization agent pentaerythritol,the carbonization accelerator ammonium polyphosphate and the foaming agent melamine were used to prepare the intumescent flame retardant system,and the flame retardant properties and mechanical properties of the plastic were measureded by mixing the system with polyadipylhexanediamine in different proportions.The experimental results show that the amount of flame retardant has a great effect on the strength and flame retardant property of plastics.The oxygen index increases with the increase of flame retardant.When the flame retardant reaches more than 30%,the increasing trend of oxygen index decreases.The average combustion time and smoke density decreased with the increase of flame retardant dosage.
