Description
技术领域
本发明属于润滑油技术领域，具体涉及一种离心式空气压缩机润滑油组合物。
背景技术
离心式空气压缩机体积小，重量轻，结构紧凑，零部件少，维护简单，并且冷却性好，效率高，气体输送平稳，因此在压缩机设备领域应用广泛，尤其是在食品、药品、纺织、矿山等行业，离心式空气压缩机的市场占比上升趋势明显。为了进一步提升离心式空气压缩机的工作效率，降低维护成本，扩大使用范围，近些年来，离心式空气压缩机正朝着简单化、紧凑化以及轻量化等方向快速发展，同时设备压力、温度、级压比、排气量等条件不断提高，工况更加苛刻，相应的对离心式空气压缩机润滑油的使用寿命、抗氧化、防锈、抗腐蚀等性能要求也越来越高。
现阶段的离心式空气压缩机润滑油虽然能够在一定程度上改善离心式空气压缩机润滑油的各性能(例如，抗氧化性、防锈性、抗腐蚀性、抗乳化性和抗泡性等性能)，但是其对离心式空气压缩机润滑油各性能的改善程度依然有限，使得离心式空气压缩机润滑油的各性能还有进一步改善的空间，尤其是离心式空气压缩机润滑油的防锈性还有进一步改善的空间。因此，亟需提供一种兼具更为优异的抗氧化性、锈性、抗腐蚀性、抗乳化性、抗泡性的离心式空气压缩机润滑油组合物。
发明内容
本发明的目的是提供一种离心式空气压缩机润滑油组合物，该离组合物兼具较为优良的抗氧化性、防锈性、抗腐蚀性、抗乳化性、抗泡性，可以满足苛刻工况下的离心式空气压缩机的润滑需求。
本发明所采用的技术方案是，一种离心式空气压缩机润滑油组合物，按照质量百分数包括以下组分：离子液体0.5-5％；抗氧剂0.1-1％；防锈剂0.1-1％；金属钝化剂0.05-0.5％；破乳剂0.01-0.1％；抗泡剂0.005-0.05％；余量为基础油。
本发明的特点还在于，
组合物按照质量百分数包括以下组分：离子液体2-4％；抗氧剂0.5-1％；防锈剂0.5-1％；金属钝化剂0.1-0.3％；破乳剂0.02-0.05％；抗泡剂0.01-0.03％；余量为基础油。
离子液体的结构式为：
抗氧剂为二辛基二苯胺、二壬基二苯胺、苯乙烯基辛基二苯胺、辛基丁基二苯胺、辛基戊基二苯胺、壬基丁基二苯胺和4,4’-亚甲基双(2,6-二叔丁基苯酚)中的至少一种。
防锈剂为二壬基萘磺酸钙、十二烯基丁二酸、异壬基苯氧基乙酸、十二烯基丁二酸半酯和十二烯基丁二酸单酯中的至少一种。
