New trends in the circular economy and sustainability are pointing towards the gradual elimination of standard flame retardants such as phosphorus compounds or halogenated compounds. New solutions are therefore being sought in this area and ceramizable composites could be an interesting alternative. Weak rheological properties are one of the main disadvantages of ceramizable composites. This study tested ceramizable composites composed of styrene-butadiene rubber (SBR) as a polymer matrix and mica as a mineral filler and aimed to improve the viscoelastic properties of silicone oil as a plasticizer. To characterize this composite's mechanical properties before and after ceramization, the viscoelastic properties were tested with a dynamic oscillating rheometer and the thermal behavior with a cone calorimeter. This paper also provides results showing differences (via the abovementioned properties) between vulcanization with sulfur and that with peroxide for the ceramizable composites based on SBR. The presented results, showing changes in mechanical properties, dynamic viscosity or flammability, among others, allow a better understanding of elastomeric composites with ceramizable flame-retardant systems. Such composites can find a wide range of applications, from lagging for electrical cables to building elements such as floor coverings and fire barriers.
循环经济和可持续发展的新趋势正指向逐步淘汰磷化合物或卤化化合物等标准阻燃剂。因此，人们正在该领域寻找新的解决方案，而可陶瓷化复合材料可能是一个有趣的替代方案。流变性能较弱是可陶瓷化复合材料的主要缺点之一。本研究测试了以丁苯橡胶（SBR）为聚合物基体、云母为矿物填料组成的可陶瓷化复合材料，并旨在改善作为增塑剂的硅油的粘弹性。为了表征该复合材料在陶瓷化前后的力学性能，用动态振荡流变仪测试了其粘弹性性能，并用锥形量热仪测试了其热行为。本文还给出了基于SBR的可陶瓷化复合材料在硫磺硫化和过氧化物硫化之间（通过上述性能）的差异结果。所呈现的结果，包括力学性能、动态粘度或可燃性等方面的变化，有助于更好地理解具有可陶瓷化阻燃体系的弹性体复合材料。这类复合材料可找到广泛的应用，从电缆护套到诸如地板覆盖物和防火屏障等建筑构件。
