This study focused on mould and fire resistance of Phyllostachys edulis and Pinus massoniana treated with a nano antibiotic agent, TiO2 doped-Ag, at different concentrations (10, 50, 100, 200 g·kg-1). Results showed that agent loading improved as the concentration of the nano antibiotic agent increased. Treatments were positive for mould resistance with initial mildew for treated bamboo appearing about 3 weeks later than the untreated and for treated Pinus massoniana about 4 weeks later than the untreated. In fire resistance, treated Phyllostachys edulis was about the same as untreated except for time to ignition (TTI) of treated Phyl-lostchys edulis which was 3-4 s longer. Also, treated Pinus massoniana was about the same as the untreated in effective heat of combustion (EHC) , mass loss rate (MLR) , and total smoke release (TSR) , but heat release rate (HRR) and total heat release (THR) of the treated Pinus massoniana were lower than the untreated. [Ch, 8 fig. 4 tab. 11 ref.]%采用不同质量分数(10,50,100,200 g·kg-1)的载银二氧化钛(TiO2)纳米抗菌剂分别对马尾松Pinus massoniana材和毛竹Phyllostachys edulis材进行浸渍处理,并对处理后试件的防霉性能和阻燃性能进行研究.结果表明:纳米抗菌剂处理的试件载药量随纳米抗菌剂质量分数提高而增加,处理后毛竹材的霉变时间比未处理材推迟3周左右,处理后马尾松材的霉变时间比未处理材推迟4周左右,防霉效果良好.纳米抗菌剂对毛竹材的燃烧性能无明显影响,处理材的点燃时间比未处理材延迟3～4 s.纳米抗菌剂处理的马尾松材的热释放速率和总热释放量降低,有效燃烧热(EHC)、平均质量损失率、总发烟量无明显变化.
