  • 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.
  • How does Dopo exhibit a flame retardant mechanism?
  • DOPO exhibits mainly gas phase flame retardant mechanism through the release of free radical scavangers generated during material combustion. It may also exhibit condensed phase by dehydration to form carbonaceous protective layers .
  • Which flame retardant is best for epoxy resins?
  • 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.
  • How do you make a flame retardant?
  • In a recent research, Wang et al. synthesized a flame retardant by reacting DOPO with p-dibenzaldehyde and 5-amino-2-benzimidazolinone (POBDBI) and co-cured the epoxy resin together with DDM. The sample with a loading of 1 % phosphorus (EP/POBDBI-1.0) achieved a V-0 rating and a 36.5 % LOI value.
  • How do flame retardants affect the flammability of epoxy resin?
  • The flame retardants with both phosphate and epoxy rings which formed chemical bonding with the modified epoxy resin led to the lowering of thermal degradation rate and temperature onset. The structure of the modifier also significantly influenced the flammability of the epoxy materials.
  • Can Diphenolic acid be used as a flame retardant thermoset?
  • The APP alone modified epoxy resins led to an opposite effect on Tgs. Diphenolic acid is a plant derivative regarded as a promising sustainable alternative to bisphenol A. The obtaining of high performance flame retardant bio–based epoxy thermosets containing diphenolic acid remains however a major challenge.
