Due to growing restrictions on the use of halogenated flame retardant compounds, there is great research interest in the development of fillers that do not emit toxic compounds during thermal decomposition. Polymeric composite materials with reduced flammability are increasingly in demand. Here, we demonstrate that unmodified graphene and carbon nanotubes as well as basalt fibers or flakes can act as effective flame retardants in polymer composites. We also investigate the effects of mixtures of these carbon and mineral fillers on the thermal, mechanical, and rheological properties of EPDM rubber composites. The thermal properties of the EPDM vulcanizates were analyzed using the thermogravimetric method. Flammability was determined by pyrolysis combustion flow calorimetry (PCFC) and cone calorimetry.
由于对卤化阻燃化合物的使用限制日益增加，人们对开发在热分解过程中不释放有毒化合物的填料产生了浓厚的研究兴趣。对具有降低可燃性的聚合物复合材料的需求日益增长。在此，我们证明未改性的石墨烯、碳纳米管以及玄武岩纤维或薄片可作为聚合物复合材料中的有效阻燃剂。我们还研究了这些碳和矿物填料的混合物对三元乙丙橡胶（EPDM）复合材料的热性能、机械性能和流变性能的影响。使用热重分析法分析了EPDM硫化胶的热性能。通过热解燃烧流动量热法（PCFC）和锥形量热法测定可燃性。
