Adhikari, D. De et al. Reclamation and recycling of waste rubber. Progress in Polymer Science. 25, 2000. 909-948 and PCT patent application No. WO0129122. From the above reasoning it is clear that mechanical destruction only is not capable to provide y reclaimed rubber materials of appropriate quality.
Some traditional devulcanization methods use exposing cured rubber to elevated temperatures for an extended period of time, e.g. by applying superheated steam as disclosed in PCT patent application No. WO9920380. Also is known applying alkali and softeners as further disclosed in U.S. Pat. No. 4,161,464 and No. 5,798,394. However, this “digesting reclaim process” not only severs the sulfur bonds in the polymer matrix, but also breaks the polymer chains, causing a significant degradation of physical properties of the rubber. Due to questionable cost efficiency and environmental problems, thermal devulcanization is rarely used today.
Another technique uses prior swelling of cured material by solvents (mainly, butanol) in order to facilitate subsequent destruction of sulfide bonds as disclosed in U.S. Pat. Appl. No. US20020091167 and No. US20030225171. That technique requires removal of solvent and drying reclaimed material making entire process impractical.
Reclaimed materials based on rubber crumb with binders are also widely used for manufacturing simple articles (tiles, carpets, floors etc.).
