Flame retardant-DOPO - ChemBK
Introduction. 9,10-dihydro -9-oxa -10-phosphazene -10-oxide is also called 9,10-dihydro -9-oxa -10-phosphazene -10-oxide (DOPO), which is an important new reactive phosphorus-containing flame retardant. The flame retardants synthesized by DOPO and its derivatives have the characteristics of high efficiency, halogen-free, smokeless, non-toxic

- What are reactive Dopo based flame retardants for epoxy resins?
- This review focuses on recent advances in reactive DOPO–based flame retardants for epoxy resins, including reactive monomers, curing agents and hybrid structures. There are also highlighted fire retardant mechanisms of the DOPO derivatives and thermal and mechanical features of the epoxy systems.
- What is dopamine modified Dopo da for flame retardant thermosetting epoxy resins?
- The flame retardant mechanism of flame retardant was analyzed. DOPO-DA promotes the curing process and improves the mechanical properties. In this work, we synthesized a 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide (DOPO) derivative flame retardant dopamine modified DOPO (DOPO-DA) for flame retardant thermosetting epoxy resins (EP).
- Is Dopo a flame retardant?
- DOPO contains a reactive hydrogen bond which reacts easily with epoxy resins, aldehydes, acrylates, activated double bonds of benzoquinone, making it either a good flame retardant additive precursor or an integrative flame retardant . Hence, hydrogen phosphinates or phosphonates may be attached directly to an epoxy resin.
- Are phosphorous oxidation states a flame retardant for epoxy resins?
- In conclusion, three kinds of DOPO-based derivatives with multiple phosphorous oxidation states were synthesized and applied as flame retardants for epoxy resins. FTIR and NMR spectra confirmed the successful synthesis of these DOPO-based derivatives.
- What is a reactive flame retardant (BPD) for epoxy resin?
- Huo et al. synthesized a reactive flame retardant (BPD) for epoxy resin (EP) through a 1–pot reaction (Fig. 7). BPD contained phosphorus, nitrogen and sulfur and was used as co–curing agent for DGEBA together with DDM (Table 2). Fig. 7. Synthesis of BPD (yield 85 %) . Table 2. Composition of the cured EP systems .
- Are epoxy resins flammable?
- Unfortunately, epoxy resins have the disadvantage of being highly flammable and thus require suitable modifications with reactive or non-reactive flame retardant additives. Recent literature have shown that the derivatives 9,10–dihydro–9–oxa–10–phosphaphenanthrene–10–oxide (DOPO) are the most researched flame retardants for epoxy resins.
