摘要
综述了磷系阻燃剂在阻燃机理及新型磷系阻燃剂的开发方面的进展。磷系阻燃剂以三种阻燃机理同时参与聚合物的阻燃作用,因此具有很高的阻燃效果。聚合物分子中含氧元素及燃烧时容易炭化的聚合物被阻燃效果最好。磷系阻燃剂与含氮、卤素等其他阻燃元素的复合阻燃剂是磷系阻燃剂发展方向之一。
The development of phosphorus flame retardant according to the mechanism of retarding flame and the tendency of a new flame retardant of phosphorus was summarized. The phosphorus flame retardant was actually the function of retarding flame by three kinds of retarding flame mechanism mixed reaction with polymer, as a result, it has much higher effect. When molecules of the polymer mixed with oxygon and burning, the polymer which can easily be charcoal has best passive effect of retarding flame, so it is believed that the study on complex flame retardant including DNX and other elements of retarding flame was one of the developments for phosphorus flame retardant.
