摘要:采用5因素4水平的正交试验，研究废橡胶再生的精炼补充工艺，探讨智能精炼机各参数对于进一步提高废橡胶再生性能的影响，并确定最佳精炼补充工艺参数。结果表明：精炼补充工艺对提高废橡胶再生性能效果显著，对于采用低温力化学再生技术制备的再生胶，最佳精炼补充工艺条件为辊距0.2mm，辊速30 r·min-1，速比1∶1.25，炼胶温度70℃，炼胶时间7 min。经过精炼补充，拉伸强度上升9.6%，拉断伸长率提高11.6%，撕裂强度提升3.6%，门尼黏度降低1.1%。

Abstract: By using five factors and four levels orthogonal experiment, the researchers have studied the waste rubber regeneration replenish process, and explored the parameters of intelligent refiner to further increase the impact of the reclaimed rubber′s performance, and determined the best complementary refining process parameters. The results show that the regeneration replenish process has a significant effect on improve the performance of waste rubber. For the reclaimed rubber by using low-temperature regenerative equipment and technology, the optimum conditions of the regeneration replenish process are: roller pitch is 0.2 mm, rolling speed is 30 r·min-1, rolling speed ratio is 1∶1.25, mixing temperature is 70 ℃, mixing time is 7 min, after refining supplement, tensile strength increased by 9.6%, the elongation at break increased by 11.6% and the tear strength increased by 3.6%, processing performance Mooney viscosity decrease of 1.1%.
