Various silanes, amino silane, vinyl silane, sulfur silane (TESPD), and ZS (TESPD/zinc soap complex), are added into
chlorinated isobutylene-isoprene copolymer (CIIR)/soft clay/carbon black (CB) and CIIR/hard clay/CB compounds and they
are investigated with respect to the vulcanization characteristics, the processability, and the mechanical properties. Comparing
hard clay and soft clay filled compounds, hard clay (Suprex) filled system shows a higher die C tear than the soft clay (GK)
filled one. The other properties (Mooney, extrusion torque/pressure, torque rise (MH-ML), modulus at 300%) are close to each
other. Among various silanes, the ZS treated hard clay (Suprex) compound shows the highest mechanical property following
hard clay(S)/vinyl silane(V) and soft clay(GK)/vinyl silane(V) compounds. The TESPD and the ZS effectively helps a
formation of a strong 3-dimensional network structure between silica and CIIR via coupling reaction due to bifunctional
nature of TESPD. In addition to that, the ZS added compounds show both a better processability and mechanical properties
compared to the S2 ones at low concentration due to improved compatibility between zinc soap and CIIR matrix. Only the ZS
added compound shows both improved processabilities (Mooney, Extrusion torque-& pressure) and improved mechanical
properties (degree of crosslinking, elongation modulus, tear, and fatigue to failure counts) on both CIIR/hard clay/CB and
CIIR/soft clay/CB compounds.
