Silicone rubber (SR), as one kind of highly valuable rubber material, has been widely used in many fields, e.g., construction, transportation, the electronics industry, automobiles, aviation, and biology, owing to its attractive properties, including high- and low-temperature resistance, weathering resistance, chemical stability, and electrical isolation, as well as transparency. Unfortunately, the inherent flammability of SR largely restricts its practical application in many fields that have high standard requirements for flame retardancy. Throughout the last decade, a series of flame-retardant strategies have been adopted which enhance the flame retardancy of SR and even enhance its other key properties, such as mechanical properties and thermal stability. This comprehensive review systematically reviewed the recent research advances in flame-retarded SR materials and summarized and introduced the up-to-date design of different types of flame retardants and their effects on flame-retardant properties and other performances of SR. In addition, the related flame-retardant mechanisms of the as-prepared flame-retardant SR materials are analyzed and presented. Moreover, key challenges associated with these various types of FRs are discussed, and future development directions are also proposed.
硅橡胶（SR）作为一种极具价值的橡胶材料，因其具有诸如耐高低温、耐候性、化学稳定性、电绝缘性以及透明度等吸引人的特性，已被广泛应用于许多领域，如建筑、交通、电子工业、汽车、航空和生物领域。不幸的是，SR固有的可燃性在很大程度上限制了其在许多对阻燃性有高标准要求的领域中的实际应用。在过去十年中，人们采用了一系列阻燃策略，这些策略不仅提高了SR的阻燃性，甚至还增强了其其他关键性能，如机械性能和热稳定性。这篇综述系统地回顾了阻燃SR材料的最新研究进展，总结并介绍了不同类型阻燃剂的最新设计及其对SR阻燃性能和其他性能的影响。此外，还分析并阐述了所制备的阻燃SR材料的相关阻燃机理。此外，还讨论了与这些各类阻燃剂相关的关键挑战，并提出了未来的发展方向。
