Abstract To promote the application of silicone rubber in the electronics industry, it is urgent to improve its thermal stability and flame retardancy. In this work, iron oxide nanoparticle in-situ decorated boron nitride nanosheet (FeBN) was fabricated via sol-gel method and then incorporated into addition-cure liquid silicone rubber (ALSR). It was found that FeBN uniformly dispersed in polymer and effectively improved the thermal stability and flame retardancy of ALSR. With only 2.0 phr FeBN, the T10 and LOI of ALSR were increased to 438.2 oC and 28.5%, respectively, which was attributed to the synergism of free-radical quenching capability and layer barrier effect.

用于阻燃硅橡胶的氧化铁纳米颗粒修饰氮化硼纳米片的制备

摘要 为促进硅橡胶在电子行业的应用，迫切需要提高其热稳定性和阻燃性。在这项工作中，氧化铁纳米颗粒原位装饰氮化硼纳米片（FeBN）通过溶胶-凝胶法制备，然后加入到加成固化液体硅橡胶（ALSR）中。结果表明，FeBN均匀分散在聚合物中，有效提高了ALSR的热稳定性和阻燃性。仅使用 2.0 phr FeBN，ALSR 的 T10 和 LOI 分别增加到 438.2 oC 和 28.5%，这归因于自由基淬火能力和层阻挡效应的协同作用。
