硅烷偶联剂处理竹粉化学结构变化及其反应路径OA北大核心CSCDCSTPCD
Chemical Structure and Reaction Scheme of Modified Bamboo Powder with Silane Coupling Agent
利用X射线光电子能谱(XPS)、X射线粉末衍射(XRD)和红外光谱(IR)研究硅烷偶联剂(KH-560)改性前后竹粉结构的变化,并推测硅烷偶联剂对竹粉表面改性的机理.实验结果表明,KH-560水解后,通过形成氢键和脱水缩合两个阶段结合到竹粉的表面.硅烷偶联剂改性后的竹粉结晶结构没有明显的变化,IR谱图出现了醚键的吸收,XPS在101.18 eV处出现了Si的发射峰,C1s分峰所对应的结合能由288.16 eV变为288.52 eV,氧原子在530…查看全部>>
The bamboo powder modified with the silane coupling agent of KH-560 (KB) was studied by X-ray photoelectron spec-troscopy (XPS) , X-ray diffraction (XRD) and Fourier transform infrared (FT-IR) spectroscope. The modified mechanism was also investigated in this work. Results showed that the hydrolysis of KH-560 was found to enhance the attachment on the surface of bamboo powder by the formation of hydrogen bond and dehydration condensation. XRD analysis indica…查看全部>>
