炭黑N330填充型粉末NR密炼机塑炼工艺的研究

Mastication conditions of black N330-filled powdered NR using internal mixer

采用Brabender转矩流变仪研究炭黑N330填充型粉末NR[P(NR/N330)]的密炼机塑炼工艺特性。结果表明,P(NR/N330)的塑炼温度低于块状NR;P(NR/N330)适宜的塑炼工艺条件为:温度90℃,转子转速70r.min-1,时间5min。

The mastication conditions of black N330-filled powdered NR[-P（NR/N330）] in internal mixer were investigated by using Brabender torque rheometer. The results showed that the mastication temperature of P（NR/N330） was lower than that of block NR;the suitable mastication conditions of P（NR/N330） were as follows.mastication temperature at 90 ℃ ,rotor speed at 70 r · min^-1 ,and mastication time of 5 rain.
