Abstract
Crumb rubber obtained from recycled tires is subjected to an interlinked substitution process. The process utilizes a reactive component that interferes with sulfur bonds. The resulting treated rubber exhibits properties similar to those of the virgin composite rubber structure prior to being granulated, and is suitable for use in fabricating new tires, engineered rubber articles, and asphalt rubber for use in waterproofing and paving applications.
Claims26
A polymeric matrix comprising a crosslinked network of end-of-life tire-derived rubber and at least one auxiliary polymer, wherein a reactive moiety of the auxiliary polymer is reacted with a polycyclic aromatic hydrocarbon so as to form a chemical bond, whereby the polymeric matrix sequesters the polycyclic aromatic hydrocarbon.
