对混有炭黑、小料和混炼胶的废密炼机转子密封油（废机油）进行回收再利用，研究其在轮胎垫带胶中的应用。结果表明：废机油静置后分离出的上层澄清液体，以不大于4%的比例（质量含量）掺入芳烃油中，不影响芳烃油的正常使用；添加2份废机油中间层和下层分离产物，并调整加料顺序，试验配方胶料的加工性能和物理性能与生产配方相当，试验配方成品垫带的物理性能满足企业标准要求，停放后成品垫带表面无油污渗出，不变色，外观未出现异常现象。将废机油回收并用于芳烃油和垫带胶中，具有良好的经济效益和环保效应。

The waste sealing oil of mixer was recycled and applied in the tire lfap. The recycled oil contained carbon black, additives and some rubber compound. After allowed standing, the recycle oil was separated into clear oil in the upper layer and residue mixture in the middle and bottom layers. The upper layer clear oil was then added into aromatic oil and showed no negative effect on the normal use of the aromatic oil if the percentage of recycled oil did not exceed 4%. The residue mixture in the middle and bottom layers was applied in the tire lfap at the addition level of 2 phr. By adjusting the mixing process, the processing properties and physical properties of the rubber compound showed no change, and the performance of the ifnished lfap met the requirements of enterprise standard. The experimental results also showed that, there was no stain or oil bleed, no color change or appearance change after storage of the finished products. The application of recycled oil in the aromatic oil and the flap compound would deliver good economic and environmental beneifts.
