The invention provides a preparation method of a rubber aid 1,6-bis(N,N-dibenzyl carbamyl disulfide) hexane. According to the method, 1,6-dimercaptohexane is used as a raw material and reacts with hydrogen peroxide to form 1,2-dithiocyclooctane, then the 1,2-dithiocyclooctane reacts with chlorine to form 1,6-secondary sulfonyl chloride octane, and the 1,6-secondary sulfonyl chloride octane reactswith dibenzyl dithiocarbamate to form a final product. The synthesis process is simple and easy to operate, the reaction time is shortened, and the production efficiency and the yield are improved. According to the method, no toxic and harmful substance formaldehyde is used, no 1,6-dithiosulfo hexane disodium salt hydrate is used, a large amount of organic wastewater containing inorganic salt is reduced, the used solvent can be reused after simple treatment, and the process is clean and environmentally friendly.
