“…Simultaneously, the thermal decomposition rates of composites with 2 wt.% and 6 wt.% SiC are essentially the same, but higher than those of composites with 4 wt.% SiC. However, in the temperature range of 500-650°C, the decomposition rate of the SR composites surpasses that of pure SR, and the weight loss can be ascribed to the breaking of Si-O-Si bonds [14]. The provided data indicates that the introduction of SiC enhances the thermal stability of silicone rubber by SiC's high melting point and thermal stability [15].…”

This study focuses on modifying silicone rubber using silicon carbide (SiC) to enhance the flame retardancy and thermal insulation properties of the composites. The study characterizes the thermal stability, mechanical properties, and flame retardancy of the composite materials. The results demonstrate the effective improvement in thermal stability achieved by incorporating SiC into the silicone rubber composites. At a SiC addition level of 6 wt.%, the composite material shows optimal thermal stability with an initial decomposition temperature of 487°C, which is 84°C higher compared to the pure matrix. Additionally, the SiC/SR composites system exhibits a char yield of 72.13% at 900°C, representing an approximately 9% increase compared to the pure SR matrix. Simultaneously, the incorporation of SiC significantly enhances the flame retardancy of silicone rubber. At a SiC addition level of 10 wt.%, the LOI (Limiting Oxygen Index) value increases by 10.5% to reach 30.4%, surpassing the non-additive sample. Moreover, the UL-94 classification of the composite material is V-0, meeting the standard for flame retardant materials.

“…Therefore, a reasonable flame-retardant mechanism for RPUF composites containing CS/PCM was proposed, as shown in Figure 14. From the perspective of the vapor flame-retardant mechanism, when the shell of CS/PCM is attacked by flames, a large number of non-flammable gases (water, carbon dioxide and nitrogen dioxide) will be released, which can dilute combustible gases and oxygen in the vapor phase, thus improving the flame-retardant performance of RPUF composites [33,34]. In terms of the condensed phase, chitosan can form a C-N bond, promote the formation of a protective carbon layer and reduce the generation and emission of smoke [35].…”

The flammability of rigid polyurethane foam (RPUF) limits its application. A new type of chitosan phase-change microcapsule (CS/PCM) was successfully prepared by the condensation method with chitosan and gum acacia as the wall material and paraffin as the core material. CS/PCM was introduced into RPUF composite material as filler to improve the thermal and flame-retardant properties of polyurethane. The morphology, structure, thermal properties and flame retardancy of the materials were characterized by scanning electron microscopy (SEM), X-ray diffractometer (XRD), thermogravimetric (TG) analysis, differential scanning calorimetry (DSC) and cone calorimetry. It is found that when the CS/PCM content is 30 wt%, the latent heat of phase transition of RPUF-30 is 12.308 J/g, the limiting oxygen index (LOI) is 26.1% and the fire risk is reduced. The flame-retardant mechanism shows that the barrier effect provided by chitosan plays an important role in effectively blocking the transfer of heat and combustible gas, and improving the flame-retardant property of the composite. This paper provides a new idea for the application of CS/PCM in RPUF.
