碳酸钙的表面辐照处理──丙烯酰胺在碳酸钙粉末上的接枝聚合

Surface Modification of CaCO_3 Filler by Radiation──Graft Copolymerization of Acrylamide on CaCO_3 Powder by Electron Beam Preirradiation

本文采用电子束预辐照方法，将丙烯酰胶接枝到碳酸钙粉末填料上，用傅里叶红外光谱（ＦＴＩＲ）、顺磁共振（ＥＳＲ）、扫描电镜（ＳＥＭ）及接触角测定等手段对其表面结构和性质进行了研究．最后探讨了碳酸钙表面辐照接枝反应的机理．

Electron beam preirradiation method has been used to graft acrylamide onto calcium cabonate (CaCO3) powder. The surface structure and properties of modified CaCO3 are studied by FTIR, ESR, SEM and determination of contact angle. The suiface modification mechanism of CaCO3 by radiation is also discussed.
