【 摘 要 】

Acrylonitrile butadiene styrene rubber (NBR) has been widely applied in the automotive industry. However, unfilled NBR has poor properties. The purpose of this publication was to study the effects of carbon black (CB) variations on the thermal degradation and swelling resistance of NBR blends. The CB used in this study were HAF, SRF, and the combination of HAF and SRF. NBR samples with different carbon black fillers were prepared by a two-roll mill. The thermal stability and swelling resistance were studied by TGA (heated in oxygen with heating rates of 10, 15, and 20 °C/min at 30-600 °C) and immersed by IRM 903 for 72 h. The degradation of NBR composites occurs in two stages. The kinetic parameters of the degradation process were studied by applying Coats and Redfern method. The filled NBR composites have better thermal and swelling resistance than unfilled NBR composite. The swelling percentage and percentage of mass decomposed at 600 °C were 6.3% and 53.34% for HAF-composite, 6.9% and 56.05% for SRF-composite, and 2.1% and 57.17% for HAF/SRF-composite. Unfilled NBR gives swelling percentage and percentage of mass decomposed of 27.1% and 78.56%. HAF is the proper filler for NBR composite to reach a good thermal and swelling resistance.
