    Abstract: The invention belongs to the field of rubber tire processing, and particularly discloses an application of a lignin in preparing a radial tire, wherein the lignin is capable of completely or partially replacing resorcinol, and meanwhile, the lignin is also capable of completely or partially replacing an anti-aging agent. Compared with the prior art, the resorcinol is replaced or partially replaced by a biomass-derived lignin or a modified lignin in the invention, so that requirements of cost reduction, environmental protection and no toxicity are satisfied. Especially, the lignin modified by demethylation according to the invention is capable of effectively enhancing various properties of rubber.
