Description
技术领域
本发明属于润滑油领域,具体涉及一种抗氧化的民用润滑油及其制备方法。
背景技术
润滑油基础油主要分矿物基础油、合成基础油以及生物基础油三大类。矿物基础油应用广泛,用量很大(约95%以上),但有些应用场合则必须使用合成基础油和生物油基础油调配的产品,因而使这两种基础油得到迅速发展。
植物油基的润滑油是一种环境友好的润滑油,如豆油、玉米油、菜籽油、棉籽油等,其中最早进入市场的是德国用菜籽油(含油量35~40)合成的润滑油。但菜籽油凝点较高,低温时容易凝固,酯化后低温性能不理想。菜籽油的氧化稳定性较差,在高温时容易形成油泥和沉淀物。因此,能否以植物油为基础制备出合适的润滑油,是值得研究的课题。
发明内容
针对上述问题,本发明要解决的技术问题是提供一种抗氧化的民用润滑油及其制备方法。
为实现上述目的,本发明的技术方案为:一种抗氧化的民用润滑油,按照重量份包括以下组分:植物油10~30份、油酸三乙醇胺10~12份、α-烯烃聚合物5~10份、聚己二酸丙二醇酯 10~15份、二丙二醇二苯甲酸酯 5~10份、氯化石蜡3~6份、有机硅氧烷2~10份、硼酸3~8份、抗乳化剂3~6份、三乙醇胺5~10份、有机钼1.5~7.5份、烷基二苯胺3~6份、添加剂0.3~2.5份。
进一步地,植物油10份、油酸三乙醇胺10份、α-烯烃聚合物5份、聚己二酸丙二醇酯10份、二丙二醇二苯甲酸酯 5份、氯化石蜡3份、有机硅氧烷2份、硼酸3份、抗乳化剂3份、三乙醇胺5份、有机钼1.5份、烷基二苯胺3份、添加剂0.3份。
进一步地,所述的α-烯烃聚合物包括C10~C500的聚丙烯、C10~C500的聚1-丁烯和C10~C500的聚异丁烯。
进一步地,所述有机硅氧烷包括液态二甲基硅氧烷、甲基乙基硅氧烷中的一种或者它们的混合物。
进一步地,所述抗氧剂选自2,4,6-三叔丁基苯酚、2,6-二叔丁基-4-壬基酚、2,6-二叔丁基对甲酚、异辛基-3-丙酸酯、β-丙酸异辛醇酯、β-丙酸正十八碳醇酯中三种或三种以上的混合物,其中,必含有2,6-二叔丁基对甲酚、β-丙酸异辛醇酯和β-丙酸正十八碳醇酯。
进一步地,所述添加剂由以下原料为组分制成:烷基苯磺酸盐10~60份,β-丙酸异辛酯20~40份,亚甲基-双-烷基二硫代氨基甲酸酯10~30份,硫磷氮型极压剂10~30份,硫化酚钙型高温清净剂5~20份。
一种抗氧化的民用润滑油的制备方法,主要包括以下步骤:
步骤1:添加剂的制备,将所需重量的烷基苯磺酸盐、β-丙酸异辛酯、亚甲基-双-烷基二硫代氨基甲酸酯加入反应釜内,混匀加热至完全熔融状态,加入硫磷氮型极压剂和硫化酚钙型高温清净剂,继续加热至120~135℃保温20~40min,混匀降温至80~90℃保温备用;
步骤2:将所需重量的油酸三乙醇胺、α-烯烃聚合物、聚己二酸丙二醇酯、二丙二醇二苯甲酸酯 加入到植物油中去,加热升温至熔化,再加入氯化石蜡,反应50~70min,降温至60℃以下,加入硼酸,继续反应20~30min,保温10~15min;
步骤3:继续对步骤2中的混合溶液进行加热至80~90℃加入有机硅氧烷,继续加热至100℃,边搅拌,边保温1~2h后冷却至40~50℃,加入抗乳化剂、三乙醇胺、有机钼、烷基二苯胺,混合均匀后冷却至室温得到所需抗氧化民用润滑油。
进一步地,所述步骤3中的室温为20~27℃。
本发明的有益效果在于:本发明提供一种抗氧化的民用润滑油及其制备方法,该润滑油防锈性、抗氧性、抗磨性能都极佳,具有良好的抑泡、消泡性能及良好的化学惰性,不与不同酸碱度、不同温度下的被消泡的介质发生化学反应;该润滑剂加入抗乳化剂,不易被发泡体系中存在的表面活性剂所增溶,化学性质稳定,用量少;抗氧化耐高温,广泛适用于民用润滑油,在酸性介质中是高效的,且特别适宜含有高碱值磺酸盐、环烷酸盐、硫化烷基酚盐的润滑油体系。本发明使用烯烃聚合物作为润滑油的主要成分之一,烯烃聚合物密度小,具有优良的耐低温性能,还能够使得润滑油具有一定的耐低温性,可以使得润滑油在低温条件下不凝结,保持原有性能。
