چکیده انگلیسی
A novel mono-component intumescent flame retardant, named as hyper-branched triazine-piperazine pyrophosphate (HTPPP), is synthesized by using cyanuric chloride, 1-boc-piperazine and phosphoric acid. Chemical structures of HTPPP are characterized by fourier transform infrared (FTIR) spectra, 31P nuclear magnetic resonance (NMR), solid-state 13C NMR, elemental analysis (EA) and inductively coupled plasma mass spectrometer (ICP-MS). The resulting HTPPP is used alone as an intumescent flame retardant for polypropylene (PP). PP/HTPPP composite can achieve a limiting oxygen index (LOI) value of 30.5% and the vertical burning test (UL-94) V-0 rating at 25â¯wt% HTPPP loading. Besides, HTPPP is thermally stable with initial decompose temperature as high as 275â¯Â°C in air atmosphere. The flame retardant mechanism is concluded based on the analysis of the char residue.
