PROCESS FOR REGENERATING A MONOLITHIC, MACRO-STRUCTURAL, INTER-PENETRATING ELASTOMER NETWORK MORPHOLOGY FROM GROUND TIRE RUBBER PARTICLES
20200190297 · 2020-06-18 ·

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.

METHOD FOR PRODUCING RECYCLED THERMOPLASTIC RUBBER MASTERBATCH WITH IMPROVED GREEN STRENGTH AND TACK
20200181372 · 2020-06-11 · ·

The embodiments of the invention relate to recycled rubber masterbatch which exhibits a sufficient level of green strength and tack. The devulcanization of thermoset rubber is provided by reactive mixing of pulverized rubber, thermoplastic matrix, main-chain backbone antidegradant and green strength enhancer in the presence of a devulcanizing promoter. The embodiments of the invention also provide a thermoplastic dynamically post-vulcanized rubber which comprises at least one devulcanized rubber masterbatch and a polymer, wherein the rubber component is dispersed as a domain in a continuous resin phase and is selectively crosslinked during melt mixing with a molten thermoplastic.
