一种微胶囊化氮－磷膨胀型阻燃剂的生产方法
摘要：
本发明公开了一种微胶囊化氮－磷膨胀型阻燃剂的生产方法,将氮－磷膨胀型阻燃剂粉碎至粒度大于400目,然后与不饱和聚酯树脂一起分散在惰性溶剂中,加入引发剂,升温到80℃～100℃,使不饱和聚酯树脂发生固化反应,从而得到以氮－磷膨胀型阻燃剂微粒为晶核,在其表面形成一层非常薄的树脂膜的产品,即微胶囊化氮－磷膨胀型阻燃剂。该产品与IFR－2000相比,其水溶性由原来20℃时的0.11%、100℃时的0.22%降至20℃时的0.04%、100℃时的0.07%。
摘要（英）：

A micro-encapsulated expansion-type N-P flame-retarding agent is prepared through pulverizing the expansion-type N-P flame-retarding agent by a granularity larger than 400 meshes, then dispersing it along with unsaturated polyester resin in inertial solvent, adding trigger, heating to 80-100 deg.C and solidifying reaction of unsaturated polyester resin so to obtain the said flame-retarding agent micro-grains as crystal nucleus with a verythin layer of resin film on it, that is the required product. Its advantage is lower water solubility.
