| Alumina was modified by different coupling agents via wet method,and the modified alumina/BR composite was prepared.The physical properties and thermal conductivity of the composite were investigated.The results showed that,the best physical properties of composites were achieved with alumina modified by silane coupling agent KH-550,and the best thermal conductivity of composites were achieved with alumina modified by stearic acid(SA).As the increase of the addition level of alumina modified by SA via dry method,the hardness,elongation at break,and heat conduction coefficient were increased distinctly.Futhermore,with addition of black N330 into the composite with SA modified alumina via dry method,the physical properties were improved,while the thermal conductivity almost unchanged. |
