| 摘 要： | 采用化学方法对无机矿物填料表面进行包覆改性，制备出具有表面纳米化结构的复合矿物颗粒，有效地改善了原有颗粒的表面形貌，提高了比表面积，通过搅拌磨湿法研磨，讨论了包覆颗粒与基体的结合方式，初步证明了包覆颗粒与基体的结合方式为化学吸附而非物理吸附，两者结合牢固，包覆层不易脱落，包覆矿物颗粒在聚丙烯（PP）中填充，其复合材料的力学性能有较大的改善。

| Abstract: | Composite mineral particles with nano-structured surface, which effectively improve surface morphology of the originals and increase specific surface area, were successfully prepared by using a chemical method. By wet grinding in a stirring mill, the coalescence between coating particles and the base was discussed. The preliminary conclusion gained shows that the coating particles are not easy to be peeled off from the base because of chemical absorption. The mechanical properties of the composite are greatly improved, when the coated mineral particles filled in polypropylene. |
