Comparison of multi-component and mono-component intumescent flame retardants for thermoplastic polyurethane composites
Conventional intumescent flame retardant (IFR) is comprised of multiple components (acid, carbon, and gas source). In comparison, “all-in-one” design of mono-component IFR is effective to impart the homogeneity to functional sources in polymer matrix, which is significant to improve the synergy against combustion. In this work, a core-shell structured mono-component IFR (MAPP@FDS) are prepared with ammonium polyphosphate (APP) and furfural-derived Schiff base (FDS) and applied to modification of thermoplastic polyurethane (TPU). TPU composite with the as-prepared mono-component IFR (TPU/MAPP@FDS) exhibits V-0 rating in UL-94 test and a limiting oxygen index (LOI) value of 32.0%, with prominent bulkiness of carbonaceous layer. Cone calorimetry tests (CCTs) showed a significant reduction in total heat release (THR) and peak heat release rate (pHRR) for TPU/MAPP@FDS compared with the TPU composites with multi-component IFR. By analyzing the morphology and composition of residual char, the flame-retardant mechanism of TPU/MAPP@FDS is reasonably proposed. This work illustrates the superiority of the integration to prepare mono-component IFR and provides a potential method in developing TPU composites with remarkable flame retardancy.
Highlights
TPU/MAPP@FDS achieves a LOI value of 32.0% and UL-94 V-0 rating.
期刊介绍：
Journal of Vinyl and Additive Technology is a peer-reviewed technical publication for new work in the fields of polymer modifiers and additives, vinyl polymers and selected review papers. Over half of all papers in JVAT are based on technology of additives and modifiers for all classes of polymers: thermoset polymers and both condensation and addition thermoplastics. Papers on vinyl technology include PVC additives.
