在上述的一种润滑油添加剂的制备方法与工艺中,所述的苯骈三氮唑脂肪酸胺盐通过邻苯三胺与亚硝酸钠反应而得。将邻苯二胺加入50℃水中溶解,再加入冰醋酸,降温至5℃,加入亚硝酸钠搅拌反应,反应物渐渐变成暗绿色,温度升至70-80℃,溶液变为桔红色,于室温放置2h,冷却,滤出结晶,用冰水洗涤,干燥得粗品,将粗品减压蒸馏,收集201-204℃(2.0kPa)的馏分,再用苯重结晶,可得熔点为96-97℃的产品,产率80%左右。
在上述的一种润滑油添加剂的制备方法与工艺中,所述的合成酯为选自元醇酯、单酯、双酯中的一种或几种的混合物,所述双酯为己二酸二辛酯、壬二酸二辛酯、癸二酸二辛酯、已二酸二癸酯、壬二酸二异癸酯、癸二酸二异癸酯、丁二酸二异辛酯、丁二酸二异癸酯、乙二醇月桂酸酯、丙二醇油酸酯中的一种或几种的混合物。
在上述的一种润滑油添加剂的制备方法与工艺中,所述的高三值环烷酸钙通过将环烷酸加入反应锅,加等量的水,搅拌升温至90-100℃,慢慢加入10-20%氢氧化钠溶液进行皂化反应,至溶液透明,pH值在7.5-9时,得环烷酸钠溶液。然后用钙盐溶液与环烷酸钠溶液进行复分解反应,再用120#汽油洗涤,将杂质去掉,再脱水、脱油、加入200#汽油调稀后得成品。
在上述的一种润滑油添加剂的制备方法与工艺中,所述的新型润滑油制备方便:将基础油、丙烯酸与醚共聚物、苯骈三氮唑脂肪酸胺盐、乙丙共聚物、合成酯、高三值环烷酸钙依次放入反应釜进行搅拌,加热至50摄氏度,搅拌40到80分钟,自然冷却至室温即可。
