Abstract: |
In this paper,two kinds of silane coupling agents and four kinds of titanate coupling agents were used to prepare magnetic nitrile rubber(NBR),and the influence of coupling agents on the magnetic properties of magnetic NBR was investigated.The results showed that the magnetic properties of the compounds with titanate coupling agents were better than those with silane coupling agents,among which the magnetic properties of the compound added with titanate coupling agent A13 were the best.With the increase of the dosage of coupling agent A13,remanence(Br),intrinsic coercivity(HCJ) and maximum magnetic energy product (BH)max increased first and then decreased,while coercivity(HCB) had no obvious change pattern.When the dosage of coupling agent A13 was 1% of the dosage of magnetic powder,the compound had the optimal magnetic properties:Br 0.224 T,HCB 165 kA·m-1,HCJJ 279 kA·m-1,(BH)max 9.7 kJ·m-3. |
