Elastomeric Compositions Comprising Reclaimed Vulcanized Elastomer Particles of Broad Size Distribution and Chemically Modified Vulcanized Elastomer Particles

Номер: US20120316283A1

Автор: Charles Rosenmayer, Frank Papp

Принадлежит: Individual

Elastomer compositions comprising uncured elastomer and reclaimed elastomer are described. In one embodiment, the compositions comprise reclaimed elastomer material (micronized rubber powder) of broad particle size distribution, which is less expensive than traditional reclaimed elastomer material with narrow particle size distribution. Further, compositions comprising reclaimed elastomer materials with broad particle size distribution perform comparably to those comprising reclaimed elastomer materials with narrow particle size distribution. In other embodiments, the compositions comprise both vulcanized and devulcanized elastomer materials. Advantageously, by using a combination of vulcanized and devulcanized material, it is possible to incorporate a greater percentage by weight of reclaimed material in to an elastomer composition, thus providing additional cost savings while maintaining high levels of mechanical properties. Further, the use of the reclaimed material reduces landfill waste resulting in a more environmentally friendly product.

A method of recycling rubber includes pre-treating vulcanized ground rubber to prevent the vulcanized ground rubber from encountering significant additional crosslinking during co-vulcanization with fresh rubber compound, and promoting better bonding between the vulcanized ground rubber and the fresh rubber compound. The ground vulcanized rubber can be coated with a layer of non-vulcanized rubber that includes cure inhibitors or other ingredients dispersed within the layer to aid in the coating process and/or co-vulcanization of the vulcanized ground rubber and fresh rubber compound. The vulcanized ground rubber can also be pre-treated with a mixture of at least one chemical curing agent inhibitor and a solvent capable of solubilizing the chemical curing agent inhibitor and dispersing the curing agent inhibitor within the vulcanized ground rubber.
