摘　　要：[Objective] The aim was to develop the compound system of paraffin emulsion and CA based on natural surfactants to improve the properties of anti- mould and anti-blue stain. [Method] The paraffin wax emulsion with different con- centrations of 0.5%, 1.0% and 2.0% was added into CA （0.3% and 0.5%） to obtain six groups of compound systems. The full-cell process was applied to treat the sapwood of Pinus spp. at size of 50 mm （L）×20 mm （R）×5 mm （T）. Anti-mould and anti-blue stain tests were conducted using Botryodiplodia theobromae Pat., Spergi/lus niger V. Tiegh and Trichoderma viride Pers.ex Fr. according to the GB/T18261-200. [Result] Both paraffin wax emulsion and CA-B could prevent wood against mould and blue stain. However, within a certain range, anti-mould and anti-blue stain ef- fects of wood samples treated by the compound systems reduced slightly as the concentration of paraffin wax emulsion increased. [Conclusion] The research provides references for advancing use of wood biomass resources in a more efficient and more environment-friendly way.[目的]该研究基于天然表面活性剂开发出了石蜡防水剂与铜唑(CA-B型)防腐剂的复配体系,考察了复配体系处理材的防霉防蓝变性能。[方法]采用0.3%和0.5%2种浓度的CA-B和0.5%、1.0%、2.0%3种浓度的石蜡乳液制备复配体系,利用满细胞法浸注处理50 mm(L)×20 mm×5 mm的南方松(Pinus spp.)试材,根据国标GB/T18261-2000针对蓝变菌可可球二孢(Botryodiplodia theobromae Pat.)和霉菌黑曲霉(Aspergillus niger V.Tiegh)、绿色木霉(Trichoderma viride Pers.ex Fr.)对复配处理材进行抗蓝变和抗霉变试验。[结果]石蜡乳液和CA-B均能改善木材的抗霉变和抗蓝变效果,但在一定范围内,石蜡乳液浓度增加对抗霉变和抗蓝变效果略有负面影响。[结论]以期促进木质生物质资源的高附加值利用,推动行业向更高效、更环保的方向发展。
