dc.description.abstract |
A novel intumescent additive was synthesized by neutralizing 3,5-diaminobenzoic acid hydrochloride salt with ammonium dihydrogen phosphate. This compound, which melts at 257 C, decomposes concurrently to release carbon dioxide gas. The flame retardant performance of this compound as a primary fire retardant and in combination with expandable graphite (EG) was evaluated by cone calorimetry. Cone calorimeter results showed that addition of 10 wt % EG alone lowers peak heat release rate (pHRR) of carbon black-pigmented polyethylene from 7106109 to 342615 kW m22, whereas addition of 27 wt % of the novel intumescent lowered it to 400616 kW m22. Combinations of these two additives were able to decrease the pHRR even further. Furthermore, the novel intumescent additive reduced the flame out time from 7736307 to 537669 s although all other EG containing samples increased it. VC 2014 Wiley Periodicals, Inc. J. Appl. Polym.
