摘要
采用硬脂酸钠为处理剂对碳酸钙晶须和硼酸铝晶须进行了表面处理,通过测定活化指数、红外谱图及偏光显微观察对晶须的处理效果进行了表征,研究了处理剂的用量、处理温度和处理时间等工艺因素对表面处理的影响。结果表明:硬脂酸钠对两种晶须的处理效果均较好,活化指数分别可达到96.5%和97.3%。其中,碳酸钙晶须的最佳处理条件:处理剂用量为45%,处理时间为50 min,处理温度为40℃;硼酸铝晶须的最佳处理条件:处理剂用量为30%,处理时间为40 min,处理温度为40℃。
The sodium stearate was used for the surface modification of calcium carbonate whiskers and aluminum borate whiskers.The modified whiskers were characterized with activation index,IR spectrum analysis and POM.The influence factors such as surfactant dosages,treated temperature and time were investigated.The results indicated that the sodium stearate has well effect on surface modification of calcium carbonate whiskers and aluminum borate whiskers.The activation index can achieve 96.5% and 97.3% respectively.The optimal treatment conditions of calcium carbonate whiskers uas fouowing： the content of the coupling agent was 45%,the treatment time was 50 min and the treatment temperature was 40 ℃.
