The effect of nano-ZnO,at concentrations of 2.0,10.0,20.0,and 40.0 g·kg~(-1),on mold resistance and flame retardance of Pinus massoniana was studied.Results showed that both drug loading and mold resistance improved as the concentration of nano-ZnO increased with the time to mold initiation for the treated P.massoniana being 3-4 weeks longer than the untreated.The time to ignition(TTI) of P.massoniana treated by nano-ZnO at 2.0 g·kg~(-1) was 7 s later than the untreated sample,and the total smoke release(TSR) with 20.0 g·kg~(-1) was lower than the untreated.The treated P.massoniana differed slightly from the untreated in heat release rate(HRR),total heat release(THR),mass loss rate (MLR),and effective heat of combustion(EHC).
