摘　　要：采用偶联剂与叶蜡石共磨的工艺方法，使叶蜡石的粉磨与改性同时进行。实验表明：共磨时，偶联剂具有明显的助磨效果，且粉体表面完全憎水化，不同偶联剂具有不同的改性效果。Pyrophyllite's surface was modified when pyrophyllite was grinded with coupling agent. It was found that coupling agent was helpful for the grinding of pyrophyllite and the surface of pyrophyllite powder showed hydrophobic nature. It was also found that the grinding efficiency was different with different coupling agent.
