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.
Claims24
A method for preparing a modified rubber, comprising:
- introducing an aqueous slurry comprising vulcanized rubber particles and an organometallic compound into an electromechanical reactor configured to generate a phase space environment with cavitation, so as to induce delamination of a rubber matrix within the vulcanized rubber particles as coordinated with disrupting sulfidic linkages.
A method for preparing a modified rubber, comprising:
- introducing into a progressive cavity pump, a screw pump, an extruder, or a turbo integrator a mixture comprising vulcanized rubber particles and an organometallic compound under pressure, so as to induce delamination of a rubber matrix within the vulcanized rubber particles as coordinated with disrupting sulfidic linkages.
