The present invention provides a non-halogen-based flame retardant composition and flame retardant resin composition wherein a small amount of addition achieves an excellent flame retardancy, an amount of elution of a flame retardant from the thermoplastic resin is extremely small even under high temperature and high humidity, and it has water-resistant property. A phosphate ester amide compound of general formula (I), a nitrogen-containing compound having a 1,3,5-triazine structure or 1,3,5-triazine fused ring structure, and optionally, a metal oxide or metal salt are used together. Further optionally, a dripping inhibitor is blended.
wherein, R1, R2, R3 and R4 are each independently hydrogen or C1-3 alkyl, R11, R12, R13 and R14 are each independently C1-3 alkylene, R15 is C1-6 alkylene, and R5 and R6 are each independently hydrogen or C1-6 alkyl.
本发明提供了一种非卤素基阻燃剂组合物和阻燃树脂组合物,在这种组合物和树脂中,只需添加少量的阻燃剂即可获得优异的阻燃性,即使在高温和高湿条件下,阻燃剂从热塑性树脂中的洗脱量也极少,并且具有防水性能。通式(I)的磷酸酯酰胺化合物、1,3,5-三嗪结构或 1,3,5-三嗪熔环结构的含氮化合物和金属氧化物或金属盐一起使用。此外,还可选择混合一种滴落抑制剂。
其中,R1、R2、R3 和 R4 各自独立地为氢或 C1-3 烷基,R11、R12、R13 和 R14 各自独立地为 C1-3 亚烷基,R15 为 C1-6 亚烷基,R5 和 R6 各自独立地为氢或 C1-6 烷基。
