微胶囊化红磷阻燃剂的研制及应用

Preparation and Application of Micro - encapsulated Red Phosphorus Retardant

论述了红磷包覆的必要性及包覆方法。分别采用酚醛树脂、脲醛树脂对红磷进行微胶囊化,检测了红磷包覆前后PH_3的释放量,研究微胶囊化红磷对MC-尼龙的阻燃性能。

The red phosphorus retardant is necessary to be encapsulated preliminarily in the application. The phenolic , urea - formaldehyde resins were used to be deposited onto the surface of the red phosphorus. The phosphine emission is compared with the encapsulated retardants to the bare red phosphorus. The flame resistance of the encapsulated retardants used in the MC - nylon products was discussed.
