摘　　要：采用酚醛树脂和密胺树脂包覆的红磷阻燃剂,分别制备了两种阻燃增强尼龙66(PA66)材料。测试了材料的外观、气味、吸水率,对金属腐蚀性能、力学性能、阻燃性、灼热丝温度和漏电起痕指数。结果表明,酚醛树脂包覆材料的气味较小,吸水率较低,冲击强度更高,而密胺树脂包覆材料的外观和对金属腐蚀性能更好,拉伸强度、弯曲强度更高。两种材料均可以达到1.6 mm V-0等级阻燃,灼热丝起燃温度775℃,漏电起痕指数都在450 V以上。Two kinds of flame retardant polyamide 66(PA66)were prepared by using phenolic resin and melamine resin encapsulated red phosphorus.The appearance,smell,water absorption,metal corrosion resistance,mechanical properties,flame retardancy,glow wire temperature and leakage tracking index of the material were tested.The test results show that the flame retardant PA66 with phenolic resin encapsulated red phosphorus has low odor,low water absorption and higher impact strength,while the flame retardant PA66 with melamine resin encapsulated red phosphorus has better appearance and metal corrosion resistance,higher tensile strength and bending strength.The ignition temperature of glow wire is 775℃,and the tracking index is above 450 V.
