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.
Claims20
A method for preparing a polymeric matrix, comprising:
- combining vulcanized rubber particles, a complementary polymer, and an organometallic compound into a mixture, so as to disrupt sulfidic linkages, and so as to induce crosslinking of the complementary polymer into the polymeric matrix;
- and
- reestablishing dislocated sulfidic linkages to establish within the matrix sulfur bridge cross linked, re-aligned laminates.
