摘要(Abstract)：

采用硬脂酸对包覆磷酸钙的氧化铁黄颜料(钙铁黄)表面进行疏水改性.采用红外光谱、XRD等技术对改性前后的钙铁黄进行表征,讨论改性剂用量、改性时间和温度对改性效果的影响.XRD测试结果表明,改性后钙铁黄的晶体结构没有改变.红外光谱分析表明,钙铁黄与硬脂酸之间存在化学吸附.采用活化指数和吸油量评价改性前后钙铁黄的疏水效果,得出最佳的改性条件:硬脂酸用量为钙铁黄质量的5%,改性时间为60 min,改性温度为150℃.此条件下钙铁黄的吸油量为30.06%,活化指数为65%.亲油性实验结果表明,通过硬脂酸改性后,钙铁黄颜料表面由亲水性变为疏水亲油性.

关键词(KeyWords)： 氧化铁黄颜料;硬脂酸;表面改性;疏水性
