| 摘 要： | 采用3-氨丙基三乙氧基硅烷（APTES）、3-巯丙基三乙氧基硅烷（MPTES）、3-甲基丙烯酰氧基丙基三甲氧基硅烷（KH570）3种硅烷偶联剂，对纳米碳酸钙进行表面改性，制备了具有表面疏水性能的纳米碳酸钙。采用红外光谱仪器与接触角测定仪对玫性前后的纳米碳酸钙进行了表征与比较，结果表明：硅烷偶联剂能成功连接到纳米碳酸钙表面；3种硅烷改性剂中，KH570改性后的接触角最大，改性效果最好；表面疏水改性有助于提高纳米碳酸钙在亲油相和在有机相中的分散性能。

| Abstract: | Nanoscale calcium carbonate powder is a very important engineering material used for packaging and polymer-based composite additive. The surface hydrophobic modification of nanoscale calcium carbonate is achieved by three silane coupling agents of APTES, MPTES and KH570, respectively. The Fourier Transform Infrared Spectrometry (FT-IR) is used to confirm the surface chemical coupling variations, and the contact angle instrument to determine its hydrophobicity. After KH570 modification, the sample of nanopowder shows the best hydrophobicity of a contact angle of 107 °. The findings are of significance to enhance its dispersity and compatibility in organic media. |
