abstract="A novel multifunctional organic-inorganic hybrid was designed and prepared based on ammonium polyphosphate (APP) by cation exchange with diethylenetriamine (DETA), shorted as DETA-APP. Then DETA-APP was used as flame-retardant curing agent for epoxy resin (EP). Curing behavior, including the curing kinetic parameters, was investigated by differential scanning calorimetry (DSC) and X-ray photoelectron spectroscopy (XPS). Flame retardance and burning behaviour of DETA-APP cured EP was also evaluated. The limiting oxygen index (LOI) value of DETA-APP/EP enhanced to 30.5 % with only 15 wt% of DETA-APP incorporated; and UL-94 V-0 rating could be easily passed through with only 10 wt% of the hybrid. Compared with DETA/EP, peak-heat release rate (PHRR), total heat release (THR), total smoke production (TSP) and peak-smoke production release (SPR) of DETA-APP/EP (15 wt% addition), obtained from cone calorimetry, were dropped by 68.3, 79.3, 79.0 and 30.0 %, respectively, suggesting excellent flame-retardant and smoke suppression efficiency. Flame-retardant mechanism of DETA-APP/EP has been investigated comprehensively. The results of all the aforementioned studies distinctly confirmed that DETA-APP was an effective flame-retardant curing agent for EP.<p /> <p>Language: en</p>",
