Novel styrene butadiene rubber and vulcanized rubber and application thereof

The novel butadiene styrene rubber is prepared according to the following method steps: a, taking SBR1502 steam stripping latex, then adding an anti-aging agent EPPD and a vulcanization accelerator dodecyl dimethyl benzyl ammonium chloride, and uniformly stirring to prepare latex; in the step, based on dry glue, the addition amount of the anti-aging agent EPPD is 0.2-0.4% of that of the styrene-butadiene rubber, and the addition amount of the vulcanization accelerator dodecyl dimethyl benzyl ammonium chloride is 0.02-0.04% of that of the styrene-butadiene rubber; b, hot water is taken, a coagulant aid CA solution and a sulfuric acid solution are added, a stirrer is started, the latex prepared in the step a is uniformly added, the latex is coagulated into particles with the uniform size, residues are washed away with warm water, and colloidal particles are prepared; and c, drying the colloidal particles prepared in the step b to obtain dry colloidal particles. The styrene-butadiene rubber is prepared by adopti
