With the increasing emphasis on environmental protection, the development of flame retardants for epoxy resin (EP) has tended to be non-toxic, efficient, multifunctional and systematic. Currently reported flame retardants have been capable of providing flame retardancy, heat resistance and thermal stability to EP. However, many aspects still need to be further improved. This paper reviews the development of EPs in halogen-free flame retardants, focusing on phosphorus flame retardants, carbon-based materials, silicon flame retardants, inorganic nanofillers, and metal-containing compounds. These flame retardants can be used on their own or in combination to achieve the desired results. The effects of these flame retardants on the thermal stability and flame retardancy of EPs were discussed. Despite the great progress on flame retardants for EP in recent years, further improvement of EP is needed to obtain numerous eco-friendly high-performance materials.
随着对环境保护的日益重视,环氧树脂(EP)阻燃剂的发展已趋向于无毒、高效、多功能和系统化。目前报道的阻燃剂已能够为EP提供阻燃性、耐热性和热稳定性。然而,许多方面仍需进一步改进。本文综述了EP在无卤阻燃剂方面的发展,重点关注磷系阻燃剂、碳基材料、硅系阻燃剂、无机纳米填料和含金属化合物。这些阻燃剂可以单独使用或组合使用以达到预期效果。讨论了这些阻燃剂对EP热稳定性和阻燃性的影响。尽管近年来EP阻燃剂取得了很大进展,但仍需要进一步改进EP以获得大量环保型高性能材料。
