摘要	本实验采用乳胶共混法在硅烷偶联剂改性二氧化硅的制备中通过乳化分散二氧化硅，并与硅烷偶联剂溶液共混反应，通过化学键合的方式与二氧化硅表面形成稳定的连接，成功将硅烷偶联剂接枝到二氧化硅表面，实现了二氧化硅的改性。通过傅里叶变换红外光谱（FTIR）分析，证实了硅烷偶联剂成功接枝到二氧化硅表面，并且改性后的二氧化硅在乳胶体系中展现了良好的分散性，阻止了基团团聚的倾向。APTS的引入显著增强了改性二氧化硅与聚丙烯（PP）的相容性和界面结合力，增强了PP工程塑料的力学性能。
Abstract	In the preparation of silane coupling agent modified nano silicon dioxide, the emulsion blending method adopted in this study disperses nano silicon dioxide by emulsification, and blends with silane coupling agent solution to form a stable connection with the surface of nano silicon dioxide by chemical bonding, and successfully grafts silane coupling agent to the surface of nano silicon dioxide, thus achieving the modification of nano silicon dioxide. By Fourier transform infrared spectroscopy (FTIR) analysis, it was confirmed that the silane coupling agent was successfully grafted to the surface of nano silica, and the modified nano silica showed good dispersion in the latex system, preventing the tendency of group agglomeration. The introduction of APTS significantly enhanced the compatibility and interfacial binding force of modified nano-silica and polypropylene (PP), and enhanced the mechanical properties of PP engineering plastics.
