以4年生新伐毛竹为试材,以褐腐菌棉腐卧孔菌为试菌,对壳聚糖铜配合物(CCC)、壳聚糖锌配合物(CZC)及相应的金属盐(氯化锌)和铜铬硼(CCB)、ACQ处理材的耐腐性能、力学性能及胶接性能进行研究.结果表明:1) CCC处理的竹材对棉腐卧孔菌的耐腐性能不及CCB和ACQ处理材;但是,随着CCC处理浓度的增加,处理材耐褐腐性能明显增加,当处理材中金属离子保持量达到5.141 kg·m-3时,腐朽后质量损失低于6.1%.2) CZC处理毛竹试材的耐腐效果低于CCC、CCB和ACQ,略高于氯化锌处理材,当CZC中金属离子保持量高于5.091 kg·m-3时,处理材的质量损失在26.4%～29.0%之间.3) 同素材(未处理材)相比,经防腐剂处理后的竹材力学性能及胶接性能均有不同程度下降,尤其是CCB处理材.在所测指标中,抗弯弹性模量和抗弯强度下降最明显,横纹抗压强度和胶接强度除CCB外变化不大.

The mechanical strength, gluing performance and decay-resistance of 4-year-old bamboo wood treated with chitosan copper/zinc complexes (CCC and CZC),CCB(copper, chromium, boron composites),ACQ and zinc chloride were reported in this paper. Results showed as follows: 1) The decay resistance of CCC against Poria placenta was inferior to CCB and ACQ. But the ability of resisting yellow-rot fungi increased greatly with the increase of CCC concentration. When the metal ion retention in bamboo wood reached 5.141 kg·m-3, mass loss of the treated bamboo wood was below 6.1%. 2) The decay resistance of CZC against Poria placenta was evidently lower than that of CCC,CCB and ACQ , but slightly better than that of zinc chloride. When the metal ion retention in bamboo wood exceeded 5.091 kg·m-3, mass losses of the treated bamboo wood were between 26.4% and 29.0%. 3) The mechanical strength and gluing performance dropped at different degrees, especially for CCB preservative. Among the experimental indexes, the values of bending modulus and bending strength decreased the most, while the compression strength vertical to grain and the gluing strength had nearly no changes except for CCB.
