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.
Claims18
An end-of-life tire-derived rubber, comprising rubber and carbon black, wherein a portion of the carbon black is surface carbon black, and wherein polyaromatic hydrocarbons resident in the surface carbon black are sequestered in the rubber by a chemical bond-forming reaction.
