摘要
The effect of nano-ZnO,at concentrations of 2.0,10.0,20.0,and 40.0 g·kg<sup>-1</sup>,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<sup>-1</sup> was 7 s later than the untreated sample,and the total smoke release（TSR） with 20.0 g·kg<sup>-1</sup> 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）.
