Preparation and properties investigation of gadolinium arylate/hydrogenated nitrile-butadiene rubber composites

摘要

The gadolinium acrylate Gd(AA)_3/hydrogenated nitrile-butadiene rubber (HNBR) composites have been prepared by in-situ reaction with dicumyl peroxide(DCP) as vulcanizing agent. The original morphology of Gd(AA)3 and its dispersion state in un-vulcanized and vulcanized rubber compound have been analyzed by scanning electron microscopy (SEM). The results demonstrated that Gd(AA)3 dispersed uniform in the composite with smaller size and better interface bonding because of the in-situ reaction. The mechanical properties of Gd(AA)_3/HNBR reached the best when filled with 40 phr Gd(AA)3 and the X-ray shielding property increased with the increasing filling amount of Gd(AA)_3.
