Synergistic Flame Retardant

Recently, widespread concern has been aroused on environmentally friendly materials. In this article, barium phytate (Pa-Ba) was prepared by the reaction of phytic acid with barium carbonate in deionized water, which was used to blend with intumescent flame retardant (IFR) as a flame retardant and was added to epoxy resin (EP). Afterward, the chemical structure and thermal stability of Pa-Ba were characterized by Fourier transform infrared (FTIR) spectroscopy and thermogravimetric analysis (TGA), respectively. On this basis, the flammability and flame retardancy of EP composites were researched. It is shown that EP/14IFR/2Ba composite has the highest limiting oxygen index (LOI) value of 30.7%. Moreover, the peak heat release rate (PHRR) of EP/14IFR/2Ba decreases by 69.13% compared with pure EP. SEM and Raman spectra reveal the carbonization quality of EP/14IFR/2Ba is better than that of other composites. The results prove that Pa-Ba can cooperate with IFR to improve the flame retardancy of EP, reducing the addition amount of IFR in EP, thus expanding the application range of EP. In conclusion, adding Pa-Ba to IFR is a more environmentally friendly and efficient method compared with others.

The cheaper phosphoric acid was uesd to replace the phosphorus oxychloride, starch was used to replace pentaerythritol and water as solvent to synthesize a new low-cost intumescent flame retardant (IFR)—starch phosphate ethylenediamine salts. The structure of the IFR was characterized with infrared spectroscopy. The IFR was used to impart flame retardancy to the Epoxy self-leveling floor (Epoxy Resin, EP) to get the fireproof Epoxy self-leveling floor. The results of test showed that 20% of IFR limit oxygen index of EP/IFR composite reach 31.0%. The results show that flame retardant catalyze the pyrolysis of epoxy resin into charcoal; Vertical burning passed UL94 V-0 rating.

Degradation Behaviour

The effect of intumescent flame retardant (IFR) contained microencapsulated red phosphorus on the flame retardance of E-44 epoxy resin (EP) was studied. The test results indicated that good flame retardancy can be realized when epoxy resin treated with 30% IFR. Thermogravimetric analysis showed that the charring amount at high temperature of EP can increase substantially when IFR was incorporated. In order to further explain this phenomenon, Dolye integration method of thermal degradation dynamics was employed to study the thermal degradation process of EP treated with IFR based on the microencapsulated red phosphrous according to the thermal gravimetry analysis results.The activation energy and reactor order of different thermal degradation stages were obtained. The results of thermal degradation dynamics implied the intumescent flame retardants can improve the flame retardance of the epoxy resin through decrease the degradation speed and increase the activation energy of the second thermal degradation stage.
