| 摘 要： | 采用热化学酚化技术对竹粉进行液化,分离得到竹纤维素微粉(BCMP)。通过对比实验,测试了竹纤维酚化前后的结构和性能。实验结果表明,竹粉中的纤维素无定型组分和木质素组分完全被酚化,而未被酚化的残渣为具有高度结晶结构的纤维素纤维;BCMP纤维质量分数达97%以上,羟值126.8 mg KOH/g,热分解温度达300℃以上,并具有比竹粉更好的疏水性、耐热性、抗紫外老化性能和抑菌性能。

| Abstract: | Bamboo cellulose micro-powder(BCMP) was obtained by the thermo-chemistry selective liquefaction of bamboo powder.The structure and performance of bamboo powder before and after liquefaction was investigated with FTIR,WXRD,Optical microscope,UV-Vis absorption and TGA,respectively.Results showed the amorphous parts among bamboo cellulose and lignin were liquefied completely,while the cellulose with higher crystalline was non-liquefied;the resultant BCMP had lower hydroxyl value of 126.8 mg KOH/g,higher cellul... |
