颜填料对膨胀型防火涂料性能的影响

Influence of Pigments and Fillers on the Intumescent Flame-Retardant Performance of the Coatings

讨论了不同颜填料及用量对涂料防火性能的影响,采用XRD和FT-IR对涂层燃烧后的产物进行表征。结果表明:添加TiO2和可膨胀石墨后,涂层的防火性能得到明显的改善;且当TiO2和可膨胀石墨添加量分别为7.5%和4%时,炭化层的强度明显增加,涂层的防火性能最好。

The influence of pigments and fillers on the intumescent flame - retardant performance of the coatings was discussed in detail in the article. And the burned products was characterized by use of XRD and FT - IR. It is shown that the flame - retardant performance of the coatings is improved with incorporation TiO2 and expandable graphite. When the TiO2 and expandable graphite in the system is 7.5 percent and d percent respectively, the intensity of char - layer is increased and the coatings shows the best flame - retardant performance.
