An Investigation of the thermal degradation of the intumescent coating containing MoO3 and Fe2O3

Intumescence: Tradition versus novelty. A comprehensive review

“…The time to reach PHRR for coatings with microencapsulated ingredients was retarded by 30 and 50s in comparison with a coating with the same loading level of APP/PER mixture. MoO 3 and Fe 2 O 3 were effective modifiers in improving the thermal stability of intumescent coating [340]. Molybdenum disilicide (MoSi 2 ) and EG were used to improve the performances of intumescent coating [341].…”

Study on intumescent flame retarded polystyrene composites with improved flame retardancy

“…By the sequence of esterification, carbonization, expansion and solidification, the intumescent char generated from the IFR will cover the underlying material to protect it from the heat or flame and slow the mass transfer [1] and [2]. Over the past decade, inorganic nanofillers (montmorillonite clay [3] and [4], carbon nanotubes, [5] zirconium phosphate [6]), metallic oxides [7], [8], [9] and [10] (MoO3, Fe2O3, TiO2, La2O3) and catalysts [11] have been added to the IFR to improve its flame retardant efficiency and thermal stability. As expected, the synergistic or catalytic effect induced by the addition will modify the chemical and/or physical behavior of the char and impart superior flame retardancy to polymeric materials, compared to those containing IFR alone.…”

Effects of organo-clay and sodium dodecyl sulfonate intercalated layered double hydroxide on thermal and flame behaviour of intumescent flame retarded polypropylene

“…4B) and left a char residue of 31 wt% at 600 C, indicating its high capacity of char-formation, and which has been discussed in the literature [27,28]. Typically, mass loss at lower temperature was due to the release of gaseous products created by decomposition of small molecules; the elimination of ammonia and water caused by intramolecular reactions of IFR took place in the range of 250-350 C. Based on the above reactions, the development of intumescent substances occurred, and carbonaceous species were gradually accumulated (350-450 C).…”
