| 中文摘要: |
| 用偶联剂A151对吸波填料羰基铁粉（CI）进行表面处理，研究偶联剂A151用量对CI/甲基乙烯基硅橡胶（MVQ）吸波复合材料性能的影响。结果表明：偶联剂A151改善了CI与MVQ的相容性，提高了复合材料的加工性能，但对硫化速度有一定影响；添加偶联剂A151的复合材料硬度和拉伸强度增大，偶联剂A151/CI用量比为2%的复合材料综合物理性能较好；复合材料的内部损耗主要为磁损耗，偶联剂A151对复合材料吸波性能的影响很小。 |
| 英文摘要: |
| In this paper，the electromagnetic wave absorbing carbonyl iron (CI) powder was pre-treated by coupling agent A151，and then the influence of A151 on the properties of CI/methyl vinyl silicone rubber(MVQ) absorbing composites was investigated.The experimental results showed that，with the pre-treatment of CI by coupling agent A151，the compatibility between CI and MVQ was improved，and the processing property of the composites was also improved，but the curing speed was affected.The hardness and tensile strength of the composites increased with A151 treatment，and the best performance of the composites was obtained when CI was treated by 2%wt of A151.It was found that the internal loss of the composites was mainly magnetic loss and addition of A151 showed little influence on the electromagnetic wave absorbing properties of the composites. |
