| 摘要:采用不同用量的硅烷偶联剂（KH-550）对纳米Al2O3表面进行改性研究,采用红外光谱和粒度仪对改性前后纳米Al2O3进行表征；并考察了改性纳米Al2O3的用量对芳纶纸抗张强度、介电强度和紧度等性能的影响。结果表明,KH-550能够成功地对纳米Al2O3进行改性,并且有助于芳纶纸性能的增强。随着KH-550用量的增加,改性后的纳米Al2O3粒径有所减小；纳米Al2O3与KH-550最佳配比为5 g∶15 mL,改性纳米Al2O3用量为6%时,芳纶纸的抗张指数和介电强度分别提高了58.3%和37.0%,但纸张的紧度变化不明显。 |
| Abstract:Nano- Al2O3 particles were modified with four different amount of silicon coupling agent KH-550 and the modified nano- Al2O3 particle size was measured. At the same time, the effects of addition amount of modified nano- Al2O3 on tensile strength, dielectric strength, tightness properties of aramid paper were studied. The tensile strength and dielectric strength of the aramid paper before and after adding nano- Al2O3 were compared. The results showed that the nano- Al2O3 particle size was reduced after modification. When the ratio of nano- Al2O3 and silicon coupling agent KH-550 was 5 g∶15 mL, the amount of modified nano- Al2O3 was 6%, the tensile strength of the paper increased by 58.3%, the dielectric strength increased by 37.0%, the paper tightness did not change significantly. |
