Abstract
Crumb rubber obtained from recycled tires is subjected to a process involving phase reticulation induced sulfidic metathesis. The process utilizes a reactive component that interferes with sulfur bonds, assisted by exposure to a pulsed magnetic field. The resulting rubber, subjected to interlinked substitution, exhibits properties similar to those of the virgin composite rubber structure prior to being granulated, or other polymeric materials, 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 recycled rubber-based elastomer, comprising:
- applying compression to a mixture comprising vulcanized rubber particles and an organometallic compound, where the mixture subject to compression is exposed to a pulsed magnetic field, whereby a recycled rubber-based elastomer is obtained.
A reactor for producing a recycled rubber-based elastomer, comprising:
- a pair of cooperating pinch rollers;
- and
- at least one electromagnet configured to expose a mixture of an organometallic compound and ground tire rubber particles to a pulsed magnetic field as it passes between the pair of cooperating pinch rollers.
