A reactive flame-retardant co-monomer (DHP) containing phosphorus in two different oxidation states (+3 and +5) was synthesized and combined with modified diatomite to prepare flame-retardant vinyl ester resin (VER) composites. At a DHP loading of 30%, the composite achieved a limiting oxygen index (LOI) of 27.1% and passed the UL-94 V-0 vertical burning test. Replacing 5% DHP with 5% modified diatomite maintained the V-0 rating and raised the LOI to 27.3%, while the peak heat release rate and total heat release decreased by 35.8% and 42.0%, respectively, compared with neat VER. The study proposes a synergistic flame-retardant strategy combining a dual-valence phosphorus-containing co-monomer with modified diatomite.
