摘要

The flammability and brittleness are two major shortages of epoxy resin (EP). Normally, adding flame retardants can deteriorate the mechanical property of EP. Herein, in this work, a reactive flame retardant (DPPO-TES) containing both Si and P was synthesized and incorporated into EP. When the content of P is only 1.0 wt%, the LOI of the modified EP (DPPO-TES/EP) reaches to 33.2%, UL-94 passes V0, THR and pk-HRR are 377.6 kw/m(2) and 103.5 MJ/m(2), respectively, which is attributed to the high flame-retardant efficiency in both condense phase and gas phase. In addition, the flexible Si-O-Si chains in the structure can significantly improve the impact strength of DPPO-TES/EP. Therefore, as a bifunctional modifier, DPPO-TES has a wide application prospect for EP materials.
