Heterogeneous two-component hydrogenation catalyst, hydrogenated nitrile butadiene rubber, and preparation methods of heterogeneous two-component hydrogenation catalyst and hydrogenated nitrile butadiene rubber

The present invention relates to a heterogeneous two-component hydrogenation catalyst, a hydrogenated nitrile butadiene rubber, and preparation methods of the heterogeneous two-component hydrogenation catalyst and the hydrogenated nitrile butadiene rubber. The heterogeneous two-component hydrogenation catalyst preparation method specifically comprises: carrying out amino modification on a silica hollow microsphere carrier by using a coupling agent, loading an active component M1 and an auxiliary agent component M2 on the carrier, drying, and carrying out H2 reduction treatment to obtain the heterogeneous two-component hydrogenation catalyst, wherein the active component M1 is selected from Pd or Rh, preferably Pd, and the auxiliary agent component M2 is selected from Zr or Ti, preferably Zr. According to the present invention, the prepared heterogeneous two-component hydrogenation catalyst has advantages of high catalytic activity, high selectivity, good stability, relatively low preparation cost, mild hydrog
