JOURNAL OF POLYMER ENGINEERING VOLUME 19:1, 1999, page 13 ABSTRACT
This study presents the results of our investigation of modifying and co-accelerating effects of oligoamide phosphate (OAPh) and its ammonium derivative (NAD) in the dibenzothiazolyl disulphide (MBTS)-accelerated sulphur vulcanizates of natural rubber (NR). It is established that both OAPh and its NAD are very effective anti-fatigue agents: The cycle number at break of the compounds containing OAPh or NAD increases by one order or more as compared with the control compound (without OAPh or NAD). NAD also demonstrates an additional accelerating effect, which is better ex-pressed when added in the second preparation stage. With respect to the cure characteristics, the use of NAD is preferred. KEYWORDS NR compounds. DBTD-accelerated, OAPh and NAD, modifying effect. fatigue resistance |
