一种合成空气压缩机润滑油组合物及其制备方法
摘要：
本发明提供了一种合成空气压缩机润滑油组合物，包含：0.1wt%~10wt%的增粘剂；2wt%~7wt%的抗氧剂；0.05wt%~1wt%的抗腐蚀剂；1wt%~8wt%的极压抗磨剂；0.0001wt%~0.05wt%的消泡剂；余量的酯类油，所述酯类油具有式（I）结构，R1、R3独立选自碳原子数为5~20的烷基，R2选自碳原子数为5~18的亚烷基。所述酯类油具有特殊的分子结构，使得所述合成空气压缩机润滑油组合物独具优异的结焦物清洗功能，能将压缩机系统原有的油泥和结焦物清洗携带出来；同时，所述合成空气压缩机润滑油组合物的抗结焦性较好。本发明还提供了一种合成空气压缩机润滑油组合物的制备方法。
摘要（英）：

The invention provides a synthetic lubricating oil composition for an air compressor. The synthetic lubricating oil composition comprises 0.1 to 10wt% of tackifier, 2 to 7wt% of antioxygen, 0.05 to 1wt% of corrosion inhibitor, 1 to 8wt% of extreme pressure anti-wear agent, 0.0001 to 0.05wt% of antifoaming agent, and the balance of ester oil. The ester oil is provided with a structure shown as formula (I), wherein R1 and R3 are independently selected from alkyl with 5 to 20 carbon atoms; and R2 is the alkylene with 5 to 18 carbon atoms. The ester oil is provided with a special molecular structure, so that the synthetic lubricating oil composition for the air compressor is excellent in function of cleaning the coking material, and original oil sludge and coking matter of the compressor system can be cleaned and carried out; and the synthetic lubricating oil composition for the air compressor is higher in coking resistance. The invention also provides a preparation method of the synthetic lubricating oil composition for the air compressor.
