Application of intercalated compound of montmorillonite
To extend the lifetime of rubber materials, the intercalated compound consisting of N, N′-diphenyl-p-phenylenediamine (DPD) as guest molecule and montmorillonite as host layer was added to chloroprene rubber (CR) and acrylonitrile-butadiene rubber (NBR). These rubber samples were either immersed in a mixture of isooctane and toluene or kept at 140°C in air, and subjected to ozone aging tests.
