In seeking for the useful reclaiming agents for conventional mechano-chemical procedure organic sulfur and their amine compounds which are usually employed as an accelerator for vulcanization were tried on a crushed tire scrap of passenger cars.
Consequently, 2-rnercaptobenzothiazolea nd its cyclohexylamines alt were found to be the most effective reclaiming agents for conventional inechano-chernical procedure.The Mooney viscosity of the reclaimed rubbers treated with these agents showed the considerably low value of 36 and 22, respectively.Thereclaimed rubbers could be revulcanized with the use of a conventional sulfur-accelerator vulcanizing system and the tensile properties of the vulcanizates obtained were superior to those of a commercially reclaimed one.
