| Summary: | The flammability of cellulosic material restricts its use in insulation and packaging applications. This study examined carbon-based additives to protect cellulose paper against thermal degradation. Carbon nanotubes (CNT) and expandable graphite (EG) were used to modify paper material. Thermal analysis was performed to examine the different modification systems. Our results showed consistently that the addition of EG resulted in an increased fire resistance in the mini fire tube (MFT) test, limited oxygen index (LOI) measurements, and mass loss calorimeter (MLC). In combination with CNT, the heat-release rate could be drastically reduced. Thermal analysis (DSC with TG analysis) revealed that EG had a longer resistance to thermal degradation. The developed composite material can be used, depending on the needs of the industry, as part of thin panel material, partition, or fireproof cladding in construction, railways, transport, automotive, and shipbuilding industries. |
