The flame retardancy of the mixture of hexa(N-hydroxymethyl)amidocyclotriphosphazene and partially methylated melamine formaldehyde resin (HHMATP/PMMM) in paper was proposed by limiting oxygen index measurement (LOI), the vertical burning test and cone calorimetry test (CCT). In our research, the LOI of washed FR-paper could still be up to 33.5%; the after flame time , and burning time were reduced to 4.8 s & 0 s, and the char length was only 12.0 mm. While the results of CCT imply that compared with non-flame retarded paper, the heat release rate (HRR) of FR-paper with HHMAPT/PMMM increases gently; the mass loss becomes significantly slow, and the prolonged maximum heat release rate (PHRR), average heat release rate (MHRR), average effective heat of combustion (MEHC) and total heat release (THR) drop greatly. According to the experimental results, HHMATP/PMMM has not only excellent flame retardancy in paper but also good water resistance, with HHMATP/PMMM playing a flame retardant role mainly by means of the condensed phase mechanism.

Badano zmniejszenie palności papieru stosując mieszaninę hexa(N-hydroxymethyl)amidocyclotriphosphazene i częściowo zmetylowanej żywicy melamine formaldehyde (HHMATP/PMMM) poprzez indeks tlenowy (LOI), test pionowego palenia i test kalorymetru stożkowego (CCT). Eksperymenty wykazały, że HHMATP/PMMM ma nie tylko dobry wpływ na ograniczenie palności papieru, ale również na jego odporność na działanie wody.
