Preparation and characterization of high efficiency
Carbon black is used extensively as filler and reinforcing agent in tire manufacturing, a process in which elemental sulfur (S 8) plays a key role as the crosslinking agent for cis-1, 4-polyisoprene . In the presence of radical initiators, sulfur atoms form bridges between the allylic sites of the polymer backbone .
Usually, the rubber, filler and methylene acceptor are prepared at high temperature, and then the rubber adhesive RA is added with accelerator and sulfur in the final refining stage. The recommended proportion is 2-5 rubber adhesive RA for each 100 rubber, and 2-5 GLR-20 resins.
