摘要
采用兼具阻燃和成炭作用的笼状磷酸酯三(1-氧代-1-磷杂-2,6,7-三氧杂双环[2.2.2]辛烷-4-亚甲基磷酸酯)(trimer)和微胶囊红磷(MRP)复配阻燃聚甲醛(POM)。采用垂直燃烧试验、极限氧指数和热重分析研究复配阻燃体系对POM的阻燃性能,并对阻燃POM的力学性能进行分析。结果表明,trimer和MRP有很好的协同阻燃性能;trimer/MRP/ME的添加量为23%时,阻燃聚甲醛达到UL 94 V-0,极限氧指数最高达29.4%。
A novel char agent and flame retardant, caged-phosphate （trimer） was compounded with microcapsulated red phosphorus （MRP） and melamine （ME） as intumescent flame retardant （IFR）, which was used to prepare flame-retarded polyoxymethylene （POM）. The flame retardancy was studied through vertical burning experiment, limit oxygen index, and thermal gravimetric analysis （TGA）. Char residue collected after vertical burning was characterized by Fourier transform infrared spectroscopy （FTIR）. And the mechanical properties of FR-POM were also studied. The results showed that there was a good synergistic effect between trimer and MRP. The trimer/MRP/ME flame-retarded POM achieves UL 94 V-0 rating, and limit oxygen index was up to 29.4 % with the loading of 23%.
