Abstract: In the process of producing cold-rolled sheet, the properties of rolling oil,such as lubrication,and emulsion stability are essential factors. This study selected pentaerythrite oleate and mineral from LiaoHe as the base oil. Then adding in diffrernt kinds of nonionic complex emulsifying agent, EP-antiwear additive, antirusting agent, foam suppressor and preservative to the water of 90%~95%, and emulsifying. This experiment used our current industry standard for the reasearch on emulsion stability. The results show that the stability of cold rolling emulsion of the esters and ethers nonionic emulsifier to the base oil is better than a single species of esters or ethers compound system; Final products meet requirements of the emulsion industry standard: After 24 h, 5% emulsion oil separating soap volume is 1.0 mL, 2% emulsion oil the bubbles are completely eliminated in 5 min.

摘要： 在薄板冷轧过程中，轧制油的润滑性、稳定性是影响薄板质量的重要因素。辽河油田减侧线油与合成酯以质量比为７∶３的比例调合作为基础油，按一定比例加入不同种类的非离子复配乳化剂、极压抗磨剂、防锈剂、消泡剂和防腐剂，并加入体积分数为９５％的水进行乳化，制备冷轧油乳化液。以我国现行乳化液使用行业标准为依据，着重考察非离子乳化剂中的酯类与醚类复配的乳化剂对冷轧油乳化稳定性的影响。结果表明，对于同一种基础油，酯类和醚类的非离子复配乳化剂的乳化稳定性比单一种类的酯类或醚类复配体系要好；最终产品符合乳化液行业使用标准。
