中文摘要:
      目的 利用电晕处理、 磷酸/硅烷偶联剂 (KH550) 溶液及二者结合的方式对竹材中竹青、 竹黄进行表面改性, 研究其表面润湿性能、 化学成分变化, 以及对所制备环保代木包装材料性能的改善。方法以水和甘油为测试液, 采用切线法测量接触角变化和进行红外光谱分析; 将经3种处理方式处理后的竹纤维与木纤维以质量比1∶1混合, 加入7%(占纤维绝干量的比例)大豆基胶粘剂后制备环保代木包装材料, 测试其物理力学性能, 并与同类材料的性能进行比较。结果 经电晕处理、 磷酸/硅烷偶联剂(KH550)溶液处理和联合处理后, 制备的环保代木包装材料的静曲强度分别为24.8, 13.1, 17.1 MPa;内结合强度分别为 1.73, 1.46, 1.68 MPa; 吸水厚度膨胀率分别为 4.9%, 6.9%和 5.9%; 密度分别为0.788,0.690和0.769 g/cm3。与未处理后所制备的环保代木包装材料相比, 经过处理后制备的环保代木包装材料在物理力学性能上均有提高。结论 3种表面处理方法改性竹青、 竹黄表面, 对竹青、 竹黄表面润湿性能的影响和环保代木包装材料性能的改善以电晕处理最为显著。
英文摘要:
      This study aimed to investigate the surface wettability and chemical composition of bamboo green and bamboo yellow that were modified by corona treatment, phosphoric acid/KH550 treatment and joint treatment. The performance of wood substitute packaging materials was also analyzed. The tangent method and IR spectra analysis were employed to study the surface wettability and chemical composition change, and the test solution were water and glycerine. Our results showed that the contact angle of bamboo green and bamboo yellow was 46.0° and 36.6° , 32.1° and 41.1° by corona treatment; 27.4° and 35.8°,4.1° and 39.3° by phosphoric acid/KH550 treatment; 39.1° and 19.1°,17.9° and 40.7° by joint treatment. In addition, the hydrogen bond (-OH) and SiO2 were broken. The MOR of the wood substitute packaging materials was 24.8 MPa, 13.1 MPa, and 17.1 MPa; the IB was 1.73 MPa, 1.46 MPa, and 1.68 MPa; the TS was 4.9%, 6.9%, and 5.9%. The density was 0.788,0.690 and 0.769 g/cm3. Compared with the untreated wood packaging materials prepared by the environment protection, the physical and mechanical properties of the performance of wood substitute packaging materials were improved after different treatments. Take together, the surface wettability of Bamboo Green and Bamboo Yellow and the performance of wood substitute packaging materials were significantly improved after treated by corona, followed by joint treatment and the phosphoric acid/KH550 treatment.
