含膦共聚酰胺/纳米蒙脱土阻燃复合材料及其制备方法
摘要：
本发明涉及一种含膦共聚酰胺/纳米蒙脱土阻燃复合材料及其制备方法。本发明主要是解决现有阻燃聚酰胺存在的无机阻燃剂用量大、易迁出、阻燃效果差、聚酰胺力学性能低和卤系阻燃聚酰胺燃烧时易造成环境污染的技术难点。本发明的含膦共聚酰胺/纳米蒙脱土阻燃复合材料，其有机蒙脱土以纳米粒子分散于由含膦预聚物和尼龙66盐聚合成的含膦共聚酰胺中。本发明的制备方法是：a)制备己二胺乙醇溶液；b)制备尼龙66盐；c)制备含膦预聚物；d)制备含膦共聚酰胺/纳米蒙脱土阻燃复合材料。本发明具有阻燃剂用量少、阻燃效率高、力学性能高、燃烧后不产生有毒、有害气体和不污染环境等优点。
摘要（英）：

The invention relates to phosphoric copolyamide/nano-meter montmorillonite flame-retardant composite material and a method for preparing the same. The invention mainly aims at solving the technical problems that the prior flame-retardant polyamide uses more inorganic flame retardant, is easy to precipitate and has poor flame-retardant effect and low mechanical property, and the halogenated flame retardant polyamide is easy to pollute the environment during combustion. The organic montmorillonite is dispersed in the form of nano-particles in phosphoric copolyamide formed by the polymerization of phosphoric prepolymer and nylon 66 salt. The method for preparing the phosphoric copolyamide/nano-meter montmorillonite flame-retardant composite material comprises the steps of preparing the solution of ethanol in hexamethylene diamine, preparing the nylon 66 salt, preparing the phosphoric prepolymer and preparing the phosphoric copolyamide/nano-meter montmorillonite flame-retardant composite material. The phosphoric copolyamide/nano-meter montmorillonite flame-retardant composite material needs less flame retardant, has high flame-retardant efficiency and high mechanical property and causes no poisonous and harmful gas during combustion to pollute the environment.
