Abstract: The environment-friendly rubber plasticizer A1220 derived from vacuum distillates of naphthenic base was prepared through hydrodeacidification -furfural refining combined process, and its application performance in SBR and radial tire tread rubber was evaluated. The results showed that the rubber plasticizer A1220 prepared met the requirements of national specification GB/T 33322-2016, and the index of SBR1763 filled with rubber plasticizer A1220 was similar to that of traditional SBR1712, which met the quality requirements of SBR superior grade. The rubber plasticizer A1220 was applied well in radial tire tread rubber and the indexes were similar to foreign TDAE products. The application performance of rubber plasticizerA1220 met the requirements of radial tire tread rubber.
