采用12-羟基硬脂酸与碱液皂化生成稠化剂来稠化菜籽油与对苯二甲酸二辛酯(DOP)的复配物,制备一种机车轮缘用的菜籽油-DOP润滑脂.探讨其不同配比对润滑脂性能的影响,在较佳配比的基础上研究添加剂的加入对润滑脂性能的影响.研究结果表明:当菜籽油与邻苯二甲酸二辛脂(DOP)的配比为6∶4时润滑脂性能较好,其滴点为148℃,锥入度为31.41mm.当石油磺酸钡作为防锈剂时,产品的防锈性能较好,达到2c级别.最大无卡咬负荷PB值为647N,与外购产品相比,增大了50.11%.
Using 12-hydroxystearic acid and alkali saponification to produce thickener to thicken the compound of rapeseed oil and dioctyl terephthalate (DOP), to prepare a locomotive rim with rapeseed oil-DOP The influence of different proportion on the performance of grease was studied, and the effect of additives on the performance of grease was studied on the basis of better ratio.The results showed that when rapeseed oil and dioctyl phthalate (DOP) is 6: 4, the dropping point is 148 ℃ and the cone penetration is 31.41mm.When barium petroleum sulfonate is used as antirust agent, the antirust property of the product is better, Reached the level of 2c.The maximum card-free bite load PB value of 647N, compared with purchased products, an increase of 50.11%.
