| 摘 要： | 以MgCl2.6H2O、磷酸三聚氰胺硼酸盐(MPB)为原料,NaOH为沉淀剂,通过原位生成法制备了膨胀型纳米复合阻燃剂nano-MH/MPB。通过IR、EDAX、XRD对其进行了表征。研究了反应温度、反应时间对MH/MPB晶粒尺寸及mMH/mMPB对MH/MPB阻燃性能的影响。反应温度低于75℃、反应时间为30 min时,MH/MPB晶粒尺寸较小,通过谢乐公式计算,MH达到纳米级;mMH/mMPB为0.25时,MH/MPB阻燃性能最好。并通过热重分析(TG)以及nano-MH/MPB/EP燃烧炭渣的红外分析,初步探讨了阻燃机理。

| Abstract: | Magnesium hydroxide/melamine phosphate borate(nano MH/MPB),a novel nano-composition intumescent flame retardant,was synthesized with the in-situ reaction method from MgCl2·6H2O sodium hydroxide(NaOH) and melamine phosphate borate(MPB) in the absence of H2O.The structure of the product was confirmed by EDAX IR and XRD.The effects of reaction temperature and time on the dimension of magnesium hydroxide were observed.The effects of mass ratio of magnesium hydroxide to MPB on the flame retardancy of nano-MH/MPB/EP were examined with the limiting oxygen test.The results show that the optimal condition of synthesis of MH/MPB is mMH/mMPB=0.25,reacting under 75 ℃ for 30 minutes.Finally,the mechanism for flame retardancy of nano-MH/MPB/EP was pilot studied by means of IR of char layer and TG of MH/MPB. |
