| 摘 要： | 通过采用羟基硅油对炭黑表面修饰, 改善炭黑与硅橡胶之间的相容性, 从而减小炭黑与硅橡胶界面热阻, 制备了高导热系数炭黑填充硅橡胶, 研究了炭黑填料与硅橡胶的相容性及炭黑/硅橡胶的导热系数。结果表明: 与原炭黑/硅橡胶体系相比, 经过羟基硅油修饰的炭黑与硅橡胶的相容性得到明显改善。当经表面修饰炭黑的质量分数为36.59%时, 表面修饰炭黑/硅橡胶的导热系数可达到0.591 W·(m·K)-1, 较同含量未修饰炭黑/硅橡胶的导热系数高38.7%。

| Abstract: | Carbon black(CB) was modified with hydroxyl silicone oil to improve the compatibility between CB and silicone rubber(SR),which resulted in diminishing the thermal interfacial resistance between CB and silicone rubber,for preparing CB/SR composites with high thermal conductivity.The compatibility between CB and SR,as well as the thermal conductivity of the CB/SR composites was investigated.The results show that the surface modified CB has a better compatibility with silicone rubber compared with the origin CB.When the loading of the modified CB was 36.59%,the thermal conductivity of the modified CB/SR composites can be as high as 0.591 W ·(m · K)-1,38.7% higher than that of the origin CB/SR composites with the same loading. |
