| description | The invention provides a rubber antioxidant and application thereof and solution-polymerized styrene butadiene rubber and a preparation method thereof. The preparation method of the solution-polymerized styrene butadiene rubber comprises the following steps: in the presence of an organolithium initiator, styrene and butadiene undergo polymerization in an organic solvent; after completion of the polymerization, a coupling reaction and a termination reaction are successively carried out; and an antioxidant is then added. The antioxidant is a rubber antioxidant containing a compound as shown in the formula (1) and a compound as shown in the formula (2). The molar ratio of the compound as shown in the formula (1) to the compound as shown in the formula (2) is (0.02-2): 1. In the formula (1), R1-R6 is respectively and separately a C1-C6 alkyl group, and n is an integer of 1-10. In the formula (2), R1-R3 is respectively and separately a C1-C6 alkyl group, and R4-R7 is respectively and separately a C10-C15 alkoxy gr |
