陶土的表面改性及其在塑料中的应用

SURFACE MODIFICATION OF KAOLIN AND ITS APPLICATION IN PLASTICS

本文研究了陶土对十二烷基磺酸钠的吸附等温线和吸附动力学曲线，测定了改性陶土的比表面、接触角、粘度和红外光谱，并讨论了其在聚丙烯中的填充效果．

The adsorption isotherm and adsorption kinetic curve of SDS on Kaolin were studied,the specific surface area,contact angle,viscosity and IR of modified kaolin were determined,and its filling efficiency in polypropylene was discussed.
