Vacuum pump oil

The invention relates to the technical field of chemical industry, and concretely relates to vacuum pump oil. The vacuum pump oil consists of the following components by mass percentage: 97% to 99% base oil and 1% to 3% of an additive, wherein the additive is selected from the group consisting of an antioxidant, an antiwear agent, a metal passivator, a detergent dispersant, and a demulsifier. Thecomponents of the vacuum pump oil of the invention are not easy to react with related pollutants in an automobile glass manufacturing process; the oxidation of the oil in use can be effectively prevented, the reaction between an oxidation product and a glass pollutant can be reduced, and the oil product life and pollution resistance can be improved. 本发明涉及化工技术领域，具体要求保护种真空泵油，其由如下质量百分比的组分组成：97％-99％的基础油和1-3％的添加剂，所述添加剂选自抗氧剂、抗磨剂、金属钝化剂、清净分散剂和破乳剂。本发明的真空泵油各组分在汽车玻璃制造工艺中不易与相关污染物发生反应；可以有效阻止在用油的氧化，减少氧化产物与玻璃污染物反应，提高油品寿命及抗污染能力。
