摘要
以月桂酰氯为改性剂对电气石的表面进行改性,以活化指数和接触角为参数考察了反应条件对电气石改性效果的影响。结果表明,当质量比为1∶1的电气石与月桂酰氯在DMF溶剂中80℃下反应5 h时,改性电气石的活化指数可达96%,所得改性电气石表面具有良好的疏水性;结构分析表明,电气石表面接枝上了疏水性的烷基,但没有影响电气石的晶体结构。
The surface modification of tourmaline powder with lauroyl chloride was studied in this paper,and the influence of reaction conditions on modified effect in terms of parameters of activation index and contact angle was also discussed.Results showed that the activation index of modified tourmaline powder reached to 96 % when tourmaline powder reacted with equiponderant lauroyl chloride for 5 h at 80 ℃ in DMF,and the modified tourmaline had excellent hydrophobic property.Structural analysis revealed that hydrophobic alkyl was attached to the surface of tourmaline powder,but it had no effect on the crystal configuration of tourmaline powder.
