摘要：In this study, honokiol epoxy resin was directly functionalized by bio-based material honokiol, which was combined with furfuryl alcohol-derived flame retardant by Diels-Alder reaction to prepare bio-based epoxy cross- linking system. After curing with 4,4 '-diaminodiphenyl '-diaminodiphenyl methane, HE1/FP0.5/DDM 1 /FP 0.5 /DDM (121.37 degrees C) offered higher glass transition temperature than EP/DDM (91.75 degrees C). Meanwhile, the HE1/FP0.5/DDM 1 /FP 0.5 /DDM exhibited excellent thermal stability and flame retardancy compared to EP/DDM. The char residue of HE1/FP0.5/DDM 1 /FP 0.5 /DDM was obviously increased from 12.8% (EP/DDM) to 35.6% at 700 degrees C. Notably, the HE1/FP0.5/DDM 1 /FP 0.5 /DDM achieved a limiting oxygen index value of 37.4% and UL-94 V-0 rating. Cone calorimeter demonstrated that the peak heat release rate, total heat release and fire growth rate of HE1/FP0.5/DDM 1 /FP 0.5 /DDM were 400.29 kW/m2, 2 , 33.45 MJ/m2 2 and 4.40 kW/m2 & sdot;s, 2 & sdot;s, reduced by 57.47%, 63.39% and 41.1% compared with EP/DDM, respectively. The satisfactory flame retardancy and smoke suppression were attributed to the flame-retardant function of FP in the condensed and gas phases. Thus, this work not only provided a simple but also eco-friendly approach to achieve flame retardant thermosets from honokiol to replace bisphenol A epoxy.
