摘　　要：采用均匀设计法,利用超临界CO2流体携带3-碘-2-丙炔基丁基氨基甲酸丁酯(IPBC)对木质材料进行防腐处理。通过高效液相色谱对处理材中IPBC的含量进行定量测定,分析处理工艺对IPBC的留着率的影响。结果表明,不同的试验材料,最佳的处理工艺也不同,对于杉木和刨花板,处理压力为14 MPa,处理温度41℃,处理时间50 min最佳,其平均留着率分别达到2.79 kg.m-3和2.09 kg.m-3;马尾松和中密度纤维板处理压力为29 MPa、处理温度44℃、处理时间为45min,平均留着率分别达到2.37 kg.m-3和2.17 kg.m-3。Using uniform design, wood and wood-based composites were treated with 3-iodo-2-propynyl butylcarbamate carried by supercritical CO2. The quantities of IPBC in wood and wood-based composites treated were measured by HPLC. The effects of the preservative treatment techniques on biocide average retentions were studied. The results indicated that the best treatment technique was 14 MPa/41℃/50 min for Chinese fir and particleboard,29 MPa/44℃/45 min for pine masson and medium density fiberboard.
