Fire‐resistant ceramifiable silicone rubber composites with excellent comprehensive property were prepared in this paper. Silicone rubber was used as the base polymer, aluminum hydroxide, magnesium hydroxide, zinc borate, and glass frits were additives. The flammability and thermal stability properties, essentially focusing on the use of the limiting oxygen index and thermogravimetric analysis, were all studied. Besides, the ceramic residues were also studied by mechanical testing, scanning electron microscopy, and X‐ray diffraction. The ceramifying silicone rubber could achieve a limiting oxygen index value of 34.8%, and the flexural strength of ceramic residues formed at 800°C was 9.7 MPa. The residue of composites was approximately 58.6% at 700°C, which is significantly higher than that of neat silicone rubber. The scanning electron microscopy analysis depicted that a dense structure was formed as formed.

具有可陶瓷化性能的阻燃硅橡胶的研究

本文制备了具有优异综合性能的耐火陶瓷化硅橡胶复合材料。硅橡胶用作基础聚合物，氢氧化铝，氢氧化镁，硼酸锌和玻璃粉为添加剂。研究了可燃性和热稳定性，主要集中在极限氧指数的使用和热重分析上。此外，还通过机械测试，扫描电子显微镜和X射线衍射研究了陶瓷残留物。陶瓷化的硅橡胶的极限氧指数值为34.8％，在800℃下形成的陶瓷残余物的弯曲强度为9.7MPa。在700°C下，复合材料的残留量约为58.6％，大大高于纯硅橡胶的残留量。
