摘　　要：以微胶囊化技术改性的次磷酸铝(E-AlHP)为阻燃剂对玻纤增强PA6进行无卤阻燃研究,采用垂直燃烧实验、拉伸冲击试验、热失重分析以及扫描电镜分析,考察了E-AlHP及其复配体系对玻纤增强PA6阻燃性能、力学性能、热性能以及炭层形貌的影响。结果表明,E-AlHP的加入有效提高玻纤增强PA6的阻燃性能,且对材料力学性能影响较小,添加量为20%时,材料达到UL94 V-0级(3.2 mm),拉伸强度、断裂伸长率、拉伸弹性模量以及缺口冲击强度分别达到121.57 MPa、3.43%、5.23 GPa及6.1 kJ/m^2。Microcapsulation technology modified aluminum hypophosphite （E-A1HP） halogen-free flame retardant glass fiber reinforced PA6 was studied by vertical burning test, tensile impact test, thermogravimetric analysis and scanning electron microscopy analysis. The effect of E-A1HP and its compounding system on the flame retardancy, mechanical properties, thermal behaviors and char morphology of flame retardant glass fiber reinforced PA6 were investigated. The results showed that the addition of E-A1HP effectively improved the flame retardancy and slightly affects the mechanical properties of glass fiber reinforced PA6. At 20 wt% loading of E-A1HP, flame retartant material achieves UL94 V-0 3.2 ram, and tensile strength, elongation at break and notched impact strength was 121.57 MPa, 3.43% , 5.23 GPa and 6. 1 kJ/m2, respectively.
