Abstract

The present application relates to rubber accelerators, and specifically disclosed are a bimetallic synergistic rubber accelerator, a preparation method thereof, and a rubber product. The preparation method of the accelerator includes the following steps: Step S1, preparing a pre-precursor powder by a sol-gel method; Step S2, performing microwave synthesis; the Step S1 specifically includes the following steps: Step S11: dissolving a cobalt salt and a manganese salt in water, adding polyethylene glycol and then stirring evenly, and adjusting the pH to 7.5-8 with an alkali solution to obtain an initial reaction solution; Step S12: reacting the initial reaction solution at 50-70° C., then drying to obtain a xerogel, and then pulverizing and screening to obtain the pre-precursor powder. The accelerator of the present application can be used to prepare rubber products. The accelerator has the advantages of shortening the vulcanization time and improving the overall performance of the rubber products.
