“…The heatproof properties of non-deteriorated lignin appear to be superior to those reported previously for a lignin-based heatproof filler, for which only a small increase in decomposition temperature was achieved even when several tens w/w lignin derivative was added 54 57 . Furthermore, lignin-based heatproof fillers previously required modification with metal 54,55 , phosphorus, and/or nitrogen 56,57 . This nondeteriorated lignin did not require addition of supporting inorganic, halogen, or phosphorus compounds.…”

“…As families of polymeric flame retardant, polyphosphoramides are highly desirable by virtue of their good thermal stability and more importantly inherent synergistic effect between phosphorus and nitrogen [3][4]. In comparison with polyphosphate, polyphosphoramides exhibit higher hydrolytic stability than polyphosphates due to the partly hydrolysable P-O-C bond substituted by P-N bond .…”

Abstract.A novel self-intumescent flame retardant of branched polyphosphoramide (BPCDC), was synthesized by the solution polymerization. The chemical structure of BPCDC has been demonstrated by fourier transform infrared spectroscopy (FTIR), and the flame-retardant properties of EP/BPCDC composites was investigated by vertical burning (UL-94), limiting oxygen index (LOI), and the cone calorimeter (CONE) test. The results rereveal that the BPCDC could effectively improve the flame-retardant performance of EP, When the 15 wt % BPCDC loading, the EP composite reached an LOI value of 32.9 % and a V-0 rating in the UL-94 test, and the peak of heat release rate and total heat release value was decreased by 54.8 % and 42.7%, respectively. The flame retardancy properties of EP/BPCDC composites with APP was also investigated, and the test results rereveal that BPCDC have a synergistic effect with APP in flame-retardant epoxy resins.

Influence of expandable graphite on flame retardancy and mechanical properties of organic-inorganic hybrid material based on sodium silicate and polyisocyanate has been investigated. The results of mechanical measurement show that adding expandable graphite decreases the maximum of the compressive strength from 5.98 to 1.49 MPa. The thermal property is evaluated by thermal conductivity test, thermogravimetric analysis. The results indicate that adding the expandable graphite increases thermal conductivity of composite and lowers maximum heat release rate. The material with expandable graphite has better flame retardancy than original material with an obvious decrease in heat release rate, fire spread and thermal decomposition rate. What is more, intumescent graphite has the obvious effect to suppress flame and prevent the composite from fire. Scanning electron microscope shows that many large particles and gaps appear after compression deformation.
