阻燃耐热聚酮的制备及其性能研究

Preparation and Properties Research of Flame Retardant and Heat Stabilized Polyketone

制备了系列阻燃聚酮材料并考察了材料的阻燃性能、机械性能、热稳定性和耐候性。结果表明,阻燃剂的引入提升了材料的阻燃性能,但是降低了材料的冲击强度和热稳定性能。通过添加热稳定剂和光稳定剂可以有效改善材料的热稳定性和耐候性能。

In this paper,flame retardant and heat stabilized polyketone was prepared.The flammability properties,mechanical properties,heat stability and weathering resistance of polyketone were investigated.The results show that the addition of flame retardant could improve the flame retardency,however,the impact strength and heat stability are decreased.The addition of heat stabilizers and light stabilizers could effectively improve the heat stability and weathering resistance.
