Abstract

In order to improve the fire resistance of wood,a novel phosphonitrile branched flame retardantHT was synthesized by using hexachlorocyclophosphazeneHCCP and tris 2-hydroxyethyl isocyanurateTHEIC),and a wood fire retardant coating was prepared by HT and isocyanatopropyltriethoxysilaneIPTS)。The transparencythermal stabilityhardness and flame retardancy of the coating were investigated. The results showed that the coating was highly transparentthe pencil hardness reached 3Hthe oxygen index increased by 30%and the vertical combustion UL-94 test reached V-0 level. The results of cone calorimetry showed that the maximum heat release rate and total heat release of the coating-treated wood were reduced by 25. 5% and 53. 2%respectivelycompared with pure wood. Meanwhilethe coating could make the generated char denser and more intactand it could effectively block heat and combustible gasesso the fire resistance of the wood can be improved.
