改性纳米硫酸钡在NR/BR并用胶中的应用

研究改性纳米硫酸钡对NR/BR并用胶性能的影响。试验结果表明，采用改性纳米硫酸钡部分替代炭黑，NR/BR并用胶的焦烧时间和正硫化时间延长，加工性能和耐热空气老化性能良好，耐屈挠性能优异，滞后损失和生热较低。;The effects of modified nano-barium sulfate on the properties of NR/BR blend were investigated.The test results showed that，by partly replacing carbon black with modified nano-barium sulfate，the NR/BR blend possessed longer scorch time and optimum curing time，better processibility and hot air aging resistance，excellent flex fatigue property，lower hysteresis loss and heat build-up
