摘　　要：以慈竹为原料,酚醛树脂(PF)为胶黏剂,硼酸锌(ZB)、硼硼合剂(SBX)为防霉剂,五氯酚钠(Na-PCP)为对照药剂制备慈竹重组材,研究添加ZB和SBX对重组竹的物理力学性能及防霉性能的影响。结果表明:ZB和SBX对蓝变菌的防治效力很差。ZB和SBX的添加会削弱板材的物理力学性能,但防霉性能显著提高。研究范围内,这2种药剂的防霉变合理使用量分别为0.70%(ZB)和0.49%(SBX)。This study investigated the effects of zinc borate （ZB）and sodiumborate/boric acid （SBX）on the physical, mechanical and mold-resistant properties of bamboo scrimber bonded with PF, and Na-PCP was taken as the control. The results showed that the effects of ZB and SBX on the blue stain-resistant efficacy were very poor. Adding ZB and SBX would undermine the physical and mechanical properties of bamboo scrimber, but highly improve mold-resistant performances of the panels. The reasonable loading levels preventing mildew for ZB and SBX were 0.70% and 0.49% ,respectively.
