摘要：

The surface of superfine magnesium hydroxide was modified with Trimethoxy[3-(phenylamino)propyl]silane. The modification mechanism was analyzed by SEM, TGA-DSC and FT-IR. The results showed that the siloxane structure grafted onto the surface of magnesium hydroxide. The modification effect was evaluated by oil absorbing rate, sedimentation time and suspension viscosity of magnesium hydroxide in liquid paraffin. The optimal dosage of silane was 1.5wt%. As a result, both of the dispersivity and lipophilicity of modified magnesium hydroxide improved remarkably.
