Abstract: The effect of crystal water on coordination crosslinking reaction of acrylonitrile-butadiene rubber(NBR) filled with copper sulfate particles containing pentahydrate(CuSO4·5H2O) was investigated in this paper. The NBR could be crosslinked in the existence of CuSO4 during heat pressing, without addition of any other crosslinking agents. The coordination crosslinking reaction is influenced by many factors, such as the temperature and time of heat pressing, the kind and content of metal salts and etc.. In addition, dynamic mechanical analysis(DMA), differential scanning calorimetry(DSC), scanning electron microscope(SEM), equilibrium swelling method and tensile test were performed for a comparison of coordination crosslinking behavior between CuSO4·5H2O/NBR and CuSO4/NBR. The results show that the crystal water in CuSO4·5H2O can accelerate the coordination crosslinking reaction between CuSO4 and NBR.
