Development of an epoxy-based self-intumescent fire protective coating containing an appropriate mass ratio of APP and Cu2O
Researchers have developed a novel epoxy-based self-intumescent fire protection coating using ammonium polyphosphate (APP) and copper (I) oxide (Cu2O) in epoxy resin (EP). The optimal composition (EP/24APP/16Cu2O) with an APP/Cu2O mass ratio of 6/4 leads to significantly better fire safety, as demonstrated in a lab-scale simulation large field test and cone calorimetry. The research provides a reference for the development of intumescent fire protection coatings with high fire safety.
