Study of flame‐retarded silicone rubber with ceramifiable property
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.
