[Method] This work combined CA with paraffin wax emulsion to treat wood samples, and basic properties of the compound system, such as stability （storage stability and centrifugal stability）, particle size and pH val-ue, and water repel ency （water absorption, shrinkage and swel ing） of treated sam-ples were investigated. [Result and Conclusion] 1） the compound systems of CA and paraffin latex had a favorable miscibility and stability; 2） compared with untreated wood, CA-treated samples showed poor water repel ing properties, whereas samples treated with the compound systems indicated an obvious reduction in water absorp-tion, and the shrinkage and swel ing of them were improved as wel .展开更多

[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.展开更多
