Description
技术领域
本发明涉及一种润滑油组合物，特别涉及一种超高真空泵油组合物。
背景技术
真空泵是从真空室中抽除气体分子，降低真空室内的气体压力，实质达到要求的真空度。真空泵油是真空泵最重要的原料之一，其油品质量直接影响设备达到的极限压力，抽气速率，背压和返油率等。按照泵的性能特点和用途，泵分为以下几类：
| 种类 | 极限压强/Pa | 主要泵的类型 |
| 真空泵 | ＜1.33 | 单级旋片泵、往复式真空泵等 |
| 中真空泵 | 0.33--0.01 | 双级旋片泵、油增压泵、水蒸汽喷射泵等 |
| 高真空泵 | 0.01--10-6 | 低温泵、溅射离子泵等 |
| 超高真空泵 | ＞10-6 | 分子泵、扩散泵等 |
分子泵就是利用泵体内高速旋转的转子，给予被撞击的气体以动能，将其驱使到高压端，由前级泵抽走；其转速越高，泵的极限真空就越高；其转子转速可高达10000-60000r/min。因此分子泵通常选用超高真空泵油，要求油品更低的饱和蒸气压、更油泥的分水性能，良好的热氧化安定性等。
专利CN106753721B公开了一种抗氧抗磨型真空泵油组合物及其制备方法，采用矿物基础油、低挥发磷酸酯和低挥发酚类抗氧剂及腐蚀抑制剂组成，具有较好的热稳定性、高真空度和抗磨性。
专利CN109666529A公开了一种合成油为主的食品级真空泵组合物，采用食品级添加剂和食品级基础油复配，满足使用要求，适用于食品加工等领域的真空泵设备。
上述专利文献中均未涉及真空泵油中离子液体类添加剂组合物中的应用，未涉及满足超高真空泵设备的油品，也未见相关报道。
