Abstract:

Facing the smoldering phenomenon of calcium alginate, the flame retardant composite was prepared by blending flame retardant polyester (FR-PET) and calcium alginate fiber (Ca-Alg) with a standard fiber dissociator. The flame-retardancy, thermal stability and morphology of the residue after conic calorimetry were characterized. The results show that when the mass ratio of FR-PET to Ca-Alg is 40∶60, the smoldering time of the composite is less than 1 s and the damage length is 12 mm. In the process of combustion, the melted FR-PET covers the surface of Ca-Alg fiber, which not only avoids the melting drop of FR-PET but also isolates the contact between Ca-Alg and air, thus inhibiting the smoldering of Ca-Alg. Furthermore, the composite has lower total heat release and total smoke production compared with FR-PET. In the third stage of mass loss of composites (350-600 ℃), the results of thermogravimetric analysis show that the intermediate products of thermal decomposition of Ca-Alg avoid the rapid decomposition of FR-PET, improves the stability of the composites and promotes the formation of residual carbon.
