为提高竹材定向刨花板（OSB）制品的耐腐性能，将竹材用碱性季铵铜（ACQ）和唑铜（CA）溶液浸渍，再用酚醛树脂粘合成两种不同规格的OSB板材，即：具有100%经处理的股线的面板和仅在面层中具有经处理的股线的面板。结果表明，经表面处理后的板材耐腐蚀性能得到了有效的提高。经处理后的板材物理力学性能均超过LY/T 1580-2010标准中OSB/4或OSB/3类的要求。统计数据分析表明，ACQ和CA预处理没有对本研究中调查的负荷水平下的面板的总体物理和机械性能产生有害影响。仅在面层中具有预处理股线的面板具有与具有100%处理股线的面板相当的耐腐蚀性和整体性能。结果表明，预处理是引入水性ACQ和CA对竹材定向刨花板进行保护的有效途径。
To enhance the decay resistance of bamboo oriented strand board (OSB) products, the strands were dipped in solutions of alkaline copper quat (ACQ) and copper azole (CA) and bonded with phenol formaldehyde resin into two types of OSB panels, i.e., panels with 100% treated strands and those with treated strands only in the face layers. The results indicated that the decay resistance of treated panels was effectively enhanced. The physical and mechanical properties of all treated panels exceeded the requirements specified for category OSB/4 or OSB/3 in the standard LY/T 1580-2010. Statistical data analysis showed that pretreatment with ACQ and CA did not have detrimental effects on the overall physical and mechanical properties of panels at the loading levels investigated in this study. Panels with pretreated strands only in the face layers had strong decay resistance and comparable overall properties as those with 100% treated strands. The results suggest that pretreatment is a promising way to introduce waterborne ACQ and CA to protect bamboo OSB.
