Abstract In this study, we investigated for synthetic hydrotalcite in chloroprene rubber
foam. Experiments were carried out to find the optimum content ratio by controlling the
contents of MgO and Hydrotalcite. Swelling test in toluene immersion was made to measure
the crosslinking density of CR foams, and the cure properties were investigated with
flat die rheometer and Mooney viscosity. The difference of hardness, tensile strength and
elongation at break were observed after immersing in 7% NaCl or 21% NaCl solutions for
a day and four days. In addition, the volume change and water content remaining in CR
foam were measured after immersing NaCl solution. As content of MgO increased, the
value of the cure torque tended to increase, but it was almost constant above 2phr of
MgO. However, the Mooney viscosity decreased with increasing MgO content. The
crosslinking density, determined by the swelling ratio, showed that the CR compound
without MgO showed a higher degree of swelling. When the content of hydrotalcite/MgO
was 3:2, it was the lowest volume change of CR form. Also, As the content of hydrotalcite
decreased, the difference of mechanical properties before and after immersion NaCl solution
increased. |
