Mechanical, morphological and thermally behaviors of natural rubber/aluminum powder composites
Different content of aluminum powder was mixed into natural rubber.Aluminum powder was modified by different coupling agents via wet method,and the modified aluminum filler/NR composite was prepared.The mechanical properties,thermal conductivity and thermogravimetric analysis of the composites was investigated.The results showed that the best physical properties and thermal conductivity of composites were achieved with saline coupling agent Si-69,and Thermo decomposing temperature of 3%TM-38S matching composites improved evidently.SEM test indicated that boundary surface of aluminium fillers and rubber was obviously improved when aluminum powder was modified by coupling agent,which would result in preferable mechanical property.The result of Thermogravimetric analysis showed that after aluminum powder filler was modified by three coupling agents,thermo decomposing temperature and hot lost weight of composites rose obviously.With the increase of A1 powder content the thermal conductivity improved greatly,Thermal conductivity of Al/NR composites lay between 0.25 and 0.47 W·m-1 ·K-1.
