中文摘要: |
采用熔融共混法制备氧化铝/甲基乙烯基硅橡胶(MVQ)导热复合材料,研究氧化铝导热网络结构和MVQ交联网络结构对复合材料导热性能和物理性能的影响。结果表明,在氧化铝导热网络开始形成至网络结构遍布整个复合材料的过程中,复合材料的导热性能随氧化铝用量的增大而提高的幅度最大;MVQ交联密度对复合材料的导热性能影响不显著,但MVQ交联密度过小会导致复合材料的导热性能略有下降。 |
英文摘要: |
The effects of Al2O3 thermal conductive network structure and MVQ crosslinking network structure on the thermal conductivity and physical properties of Al2O3/MVQ thermal conductive composite prepared by melt blending were investigated.The results showed that the thermal conductivity of composite was raised most obviously with increasing Al2O3 loading level during the evolution course from local filler-network structure to full-scale one;MVQ crosslinking density had little influence on the thermal conductivity,but when MVQ crosslinking density was very low,the thermal conductivity would be decreased slightly. |
