(NH_4)_2SO_4在热塑性塑料中的阻燃应用研究

THE STUDY ON THE FIRE RETARDANCY OF (NH_ 4)_2SO_4 IN THERMOPLASTICS

通过测定氧指数、垂直燃烧性能 ,评价了 ( NH4 ) 2 SO4 这一新型无机阻燃剂在 ABS、LDPE、PVC等热塑性塑料中的阻燃效果。结果表明 ( NH4 ) 2 SO4 是一种高效无机阻燃剂 ,在相同的用量时( NH4 ) 2 SO4 对热塑性塑料的阻燃效果优于 Al( OH) 3、Mg( OH) 2

In this paper,(NH 4) 2SO 4 was used as a new kind of inorganic flame retaardant.Fire retardancy of (NH 4) 2SO 4 in ABS、LDPE、PVC were tested by Oxygen Index and Vertical flammability.The result was that (NH 4) 2SO 4 was an effective flame retardant.Its fire retardanc was higher than that of some other inorganic flame retardant agents i.e.Al(OH) 3 and Mg(OH) 2.
