| 摘 要： | 采用MoO3、可膨胀石墨(EG)和MoO3/EG对APP/PER/MEL膨胀防火涂料进行改性,制备成改性涂料,运用隔热性能分析和热重分析(TGA)测试改性涂料的耐火极限和残碳率.结合扫描电镜分析结果,探讨MoO.EG和MoO3/EG对涂料耐火性能提高的途径分别为MoO3通过与APP/PER/MEL涂料体系作用提高了涂料残碳率;EG通过自身膨胀产生"蠕虫"结构显著改善了碳层结构;而MoO3/EG则通过MoO3和EG各自的作用,产生了明显的协同增效效果. |

| Abstract: | MoO_3,expandable graphite(EG) and MoO_3/EG were added to APP/PER/MEL coating to get MoO_3,EG and MoO_3/EG modified flame retardant coatings.The fire endurance and the char formation rate of the modified coatings are studied by the insulation and thermo-gravimetric analysis(TGA).Combined with SEM analysis,the results obtained from insulation and TGA indicated that the causes of prolongation of fire endurance after adding MoO_3,EG,MoO_3/EG in APP/PER/MEL coating were that MoO_3 increased the char formation rate through reacting with APP/PER/MEL coating,EG improved the microcosmic structure of residual char through expanding and forming worm-like structure by itself,and MoO_3/EG got good synergistic effect through respective function of MoO_3 and EG. |
