Preparation and characterization of UiO-66-NH2 adsorbed triethyl phosphate: Flame retardancy and smoke suppression for epoxy resins
The zirconium-based metal–organic framework material (UiO-66-NH2) was synthesized by solvothermal method, and its excellent adsorption performance was used to combine it with the phosphorus-based flame retardant triethyl phosphate (TEP) and to improve the flame retardant and smoke suppression properties of epoxy resin (EP). The morphology, chemical composition, and structure of the synthesized flame retardant were analyzed by scanning electron microscope, energy dispersion spectrum, Fourier transform infrared spectroscopy, and x-ray diffractometer. The cone calorimeter measurement of EP composite materials shows that EP composite materials have good flame retardant and smoke suppression properties. Compared with EP, after the UiO-66-NH2 flame retardant which adsorbs TEP is added, the peak heat release rate, total heat release, peak smoke release rate, total smoke production, carbon monoxide release rate, and carbon dioxide release rate of EP composites have been reduced. From the results of thermal analysis and scanning electron microscope, it can be seen that the synthesized flame retardant can act both in the condensed phase and in the gas phase. Thereby, the combustion of the matrix and the diffusion of the toxic gas, smoke and heat generated during the combustion are inhibited, and the flame retardant and smoke suppression effects are achieved.
Highlights
Make full use of the excellent adsorption performance of MOF.
TEP was fully adsorbed in UiO-66-NH2 pores.
UiO-66-NH2 in synergy with TEP improves EP flame retardancy.
期刊介绍：
Journal of Vinyl and Additive Technology is a peer-reviewed technical publication for new work in the fields of polymer modifiers and additives, vinyl polymers and selected review papers. Over half of all papers in JVAT are based on technology of additives and modifiers for all classes of polymers: thermoset polymers and both condensation and addition thermoplastics. Papers on vinyl technology include PVC additives.
