金属铁酸盐对聚乳酸复合材料阻燃性和热稳定性的作用研究
Influence of Ferrite Compound on Fire Retardance and Thermal Stability of PLA Composite
摘要
通过水热法合成3种不同的金属铁酸盐纳米化合物(MFe2O4,其中M代表Ni,Zn,Co),并与聚磷酸铵/可膨胀石墨(APP/EG)结合以制备聚乳酸(PLA)纳米复合材料,对复合材料的阻燃性和热稳定性进行研究。结果表明:1%(质量分数,下同)MFe2O4和12%APP/EG添加量的PLA复合材料可以达到UL-94测试的V0级别;微尺度燃烧量热测试(MCC)和热重分析(TGA)表明,PLA复合材料的阻燃性和热稳定性显著提高;材料的力学性能也得到改善;MFe2O4和APP/EG在PLA中的作用机理为基于凝聚相的促进作用。
