目的 研究硅烷基聚合物改性的纳米氧化铝悬浮体系的制备工艺。 方法 以纳米氧化铝悬浮体系中 Al2O3 的含量为考核指标,考核不同改性剂、改性剂用量、改性时间、悬浮溶剂的选择对悬浮体系的影响。 结果 确定了最优制备工艺,改性剂用量为 0. 010 mL/ g(Al2O3 ),改性时间为 30 min,悬浮溶剂为 PMA,在该工艺条件下,制备的纳米氧化铝悬浮体系中 Al2O3 的质量浓度最高可达 0. 4915 g/ mL。 结论 硅烷基聚合物可有效包覆在纳米氧化铝的表面上,实现对纳米氧化铝的改性,改性后的纳米氧化铝可制备成稳定的悬浮体系。 |

Objective To study the preparation process of siloxane-based polymer modified nano-Al2O3 suspension. Methods The nano-Al2O3 content in its suspension was used as the indicator to assess the effect of different modifiers, dosages of modifiers, modification time, and suspending solvents on the suspension. Results Optimal conditions for preparation process were determined as follows: dosage of modifiers 0. 010 mL/ g(Al2O3), modification time 30 min, and the suspension solvent was PMA. Under these conditions, the maximum content of nano-Al2O3 in its suspension was up to 0. 4915 g/ mL. Conclusion Siloxane-based polymer can modify nano-Al2O3 effectively by coating the surface,and modified nano-Al2O3 suspension is stable. |
