  • Patent number: 11434353
    Abstract: A method, and product thereof, for modifying the surface of recycled sulfur-cured rubber via surface devulcanization that minimizes alteration of the network structure of the recycled sulfur-cured rubber, while generating strong tack between mixed recycled rubber and fresh rubber for optimal adhesion upon subsequent co-curing. In one embodiment, the surface of recycled rubber is devulcanized by treating recycled rubber with a thiol and a base dissolved in a solvent that does not effectively penetrate and only minimally swells vulcanized rubbers.

  • Patent number: 10519301
    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.

  • Publication number: 20070155861
    Abstract: Methods are provided for making solution masterbatches containing a diene elastomer in an organic solvent and a silica filler, having a first average particle size, that is ground in an organic solvent to form a silica having a reduced second average particle size. Grinding of the silica in the organic solvent, with or without other ingredients including the elastomer, produces a solution masterbatch in which the silica is mixed with and well dispersed in the elastomer. The use of such desolventized solution masterbatches in vulcanizable rubber compounds results in excellent processing characteristics allowing for the reduced use of processing aids such as oil. The compound also demonstrates improved properties, including reduced hysteresis.
