| Using ferroferric oxide modified by polyethylene glycol 6000 as magnetic filler,the ferroferric oxide/NR/EPDM magnetic rubbers were prepared,and their microstructure,aging property,acid and alkali resistance,oil resistance and low temperature brittleness were investigated.The results showed that,the heat aging property,ozone resistance,acid and alkali resistance,oil resistance of modified ferroferric oxide/NR/EPDM magnetic rubber were better than those of ferroferric oxide/NR magnetic rubber,and the matrix rubber type had little influence on the low temperature brittleness of magnetic rubber. |
