Abstract

In order to improve the fire resistance of wood，a novel phosphonitrile branched flame retardant（HT） was synthesized by using hexachlorocyclophosphazene（HCCP） and tris （2-hydroxyethyl） isocyanurate（THEIC），and a wood fire retardant coating was prepared by HT and isocyanatopropyltriethoxysilane（IPTS）。The transparency，thermal stability，hardness and flame retardancy of the coating were investigated. The results showed that the coating was highly transparent，the pencil hardness reached 3H，the 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%，respectively，compared with pure wood. Meanwhile，the coating could make the generated char denser and more intact，and it could effectively block heat and combustible gases，so the fire resistance of the wood can be improved. 

Key words： phosphonitrile branched flame retardant; fire retardant coating; wood; transparency; fire resistance
