Abstract
A method of recycling rubber includes pre-treating vulcanized ground rubber to prevent the vulcanized ground rubber from encountering significant additional crosslinking during co-vulcanization with fresh rubber compound, and promoting better bonding between the vulcanized ground rubber and the fresh rubber compound. The ground vulcanized rubber can be coated with a layer of non-vulcanized rubber that includes cure inhibitors or other ingredients dispersed within the layer to aid in the coating process and/or co-vulcanization of the vulcanized ground rubber and fresh rubber compound. The vulcanized ground rubber can also be pre-treated with a mixture of at least one chemical curing agent inhibitor and a solvent capable of solubilizing the chemical curing agent inhibitor and dispersing the curing agent inhibitor within the vulcanized ground rubber.
