Abstract:
      Nitrile butadiene rubber(NBR) with good air tightness, was expected to become the ideal of inner liner raw rubber material of all steel radial tire. In order to obtain good performance of air barrier materials, the modified asphalt was selected as a two-phase compatibilizers and the relationship between the microstructure and the properties of nitrile butadiene rubber/brominized butyl rubber(BIIR) blends were investigated. Results show that the BIIR/NBR blends with compatilizer are dispersed phase small and uniform and have good processing performance and mechanical properties and its gas barrier property is equal to pure BIIR; the fatigue resistance performance is better and the best blend ratio is 80/20; resistant to ozone aging performance greatly improves after adding compatilizer.
