①阻燃效率高，能赋予复合材料良好的自熄性或难燃性；②具有良好的互容性，能与复合材料很好的相容且易分散；③具有适宜的分解温度，即在复合材料的加工温度下不分解，但是在复合材料受热分解时又能急速分解以发挥阻燃的效果；④无毒或低毒、无臭、不污染，在阻燃过程中不产生有毒气体；⑤与复合材料并用时，不降低复合材料的力学性能、电性能、耐候性及热变形温度等；⑥耐久性好，能长期保留在复合材料的制品中，发挥其阻燃作用；⑦来源广泛价格低廉。

The flame retardant efficiency is high, which can give the composite good self extinguishing or combustibility, and it has good compatibility and can be well compatible with the composite and easy to disperse; 3. It has a suitable decomposition temperature, that is, it is not decomposed at the processing temperature of the composite, but it can be rapidly decomposed to play in the heat decomposition of the composite. The effect of flame retardant; (4) non-toxic or low toxic, odorless, non polluting, no toxic gases in the flame retardant process; 5. When used with composite materials, the mechanical properties, electrical properties, weatherability and thermal deformation temperature are not reduced; (6) the durability is good and can be retained in the products of the compound material for a long time and play its flame retardancy. Use; the source is widely cheap.
