The invention relates to the technical field of new reclaimed rubber materials for tire manufacturing, in particular to bio-based compound modified liquid reclaimed rubber, a preparation method and application in tire preparation. The invention discloses bio-based compound modified liquid reclaimed rubber. The liquid reclaimed rubber is prepared from the following raw materials in parts by weight through high-temperature reaction: 100 parts of reclaimed rubber and/or rubber powder; 1.0 to 100 parts of lignin and/or lignin derivatives; and 0.05 to 5.0 parts of a peptizer. Lignin and/or lignin derivatives are/is adopted to modify the liquid reclaimed rubber, the liquid reclaimed rubber has phenolic hydroxyl groups, carbonyl groups, methoxyl groups, double bonds and carboxyl groups, and the liquid reclaimed rubber can replace tackifying resin, a softening agent and a plasticizer after being added into a rubber composition, so that the viscosity of a rubber semi-finished product is improved, the processing performance of a rubber material is improved, and the service life of the rubber material is prolonged. Meanwhile, the dispersion of the filler is facilitated, and the crosslinking density is improved, so that the performance of the rubber composition is improved, and the prepared tire has low heat generation performance.
