摘要
采用氧指数和水平燃烧两种测定方法,研究了4种氯代磷酸酯阻燃剂在软质聚氨酯泡沫塑料(PUFF)中的阻燃作用,讨论了其阻燃机理和对材料力学性能的影响,通过加速热老化实验,研究了氯代磷酸酯阻燃PUFF材料的热老化稳定性。
The flame retarding activity of four types of chloro-phosphate flame retardantsto pikyurethane flexible foams (PUFF) were investigated in this study by the oxygen indexmeasurement and the horizontal burning test. The flame ratarding mechanism and the influ-ence of the flame retardants on the mechanical properties of polymer materials are dis-cussed. The thermal ageing stability of the resultant flame retarding PUFF was also investi-gated by the accelerated thermal ageing test.
