The invention discloses a preparation process for producing engineering inner tube reclaimed rubber by using waste rubber, which comprises the following steps: S1, treating waste materials, S2, preparing auxiliary materials, S3, refining treatment: taking 200 parts of rubber powder obtained in the S1 according to a ratio, stirring and mixing the rubber powder with 20 parts of silicon dioxide nanoparticles to obtain mixed powder, drying the mixed powder at 150-180 DEG C to obtain dry powder, and performing extrusion molding on the dry powder to obtain the engineering inner tube reclaimed rubber. Adding the dry powder into a reaction kettle, and adding 5 parts of hexanethiol at the same time; 5 parts of dithiothreitol; 15 parts of paraffin oil; the temperature in the reaction kettle is 130-180 DEG C, and the reaction time is 3-5 hours. The method comprises the following steps: adding hexanethiol in the processing process of the waste rubber; a dithiothreitol; paraffin oil; methyl gallate; propyl gallate; aromatic oil; silica nanoparticles; zinc oxide; stearic acid; the plasticity and processing strength of the obtained reclaimed rubber are suitable for engineering inner tubes, and the reclaimed rubber is good in mechanical strength.
