【摘要】 研究了油品芳烃含量为５１％～９０％时，充油１，２－聚丁二烯橡胶（１，２－ＢＲ）的流变性、门尼粘度ＭＬ１００℃（１＋４）、抗湿滑性和力学性能的变化规律。结果表明，在同一剪切速率γｗ下，高芳烃含量的充油１，２－ＢＲ与低芳烃含量的相比，表观粘度ηａ增大，流变曲线斜率小，非牛顿性较强。充油１，２－ＢＲ的ＭＬ１００℃（１＋４）、抗湿滑性及拉伸强度随油品芳烃含量的增高而增大。在相同γｗ下，充油１，２－ＢＲ的ηａ随温度的升高而下降，１３０℃时的ηａ比７０℃的下降约半个数量级。更多还原

【Abstract】 The effects of the oil with 51% ～90%(mass) of aromatic content on the rheology,Mooney viscosity, wet-Skid resistance and mechanical properties of 1,2-polybutadiene rubber (1,2-BR) were studied. The experimental results showed that the apparent viscosity ηa of oil extended 1,2-BR was greater, the slope of rheological cure was less and the non-Newtonian property became greater than those of the pure one at the same shear rate γw. The Mooney viscosity increased with increasing the aromatic content of oil, and ηa decreased with increasing the temperature at the same γw. The wet-skid resistance and tensile strength increased with increasing the aromatic content.更多还原
