摘要

Influence of rubber composition on migration of N-phenyl-N'-isopropyl-p-phenylenediamine (IPPD),and N-phenyl-N'-(1,3-dimethylbutyl)-p-phenylenediamine (HPPD) to the surface in binary rubber-based vulcanizates of natural rubber (NR),styrene-butadiene rubber (SBR),and butadiene rubber (BR) was studied.Migration experiments were performed at 60 and 80 deg C for 21 days and outdoors for 4 months.Migration rates of IPPD and HPPD in the vulcanizates of SBR/NR and BR/NR blends outdors increased by decreasing the content of NR,and those in the vulcanizates of BR/SBR blends decreased with an increase of the content of BR.Migration behaviors of the antiozonants in the vulcanizates of SBR/NR and BR/NR blends at 60 and 80 deg C,on the whole,showed trends similar to the outdoor results.Migration rates of the antiozonants in the vulcanizates of BR/SBR blends at 60 and 80 deg C showed some differences.Variation of migration behaviors of the antiozoants in the binary rubber-based vulcanizates depending on rubber composition was explained by the interface between dissimilar rubbers and the intermolecular interactions between the matrices and the antiozonants.
