Abstract

The invention relates to the field of lubricating oil, in particular to ashless high-performance vacuum pump oil. The ashless high-performance vacuum pump oil is prepared from the following componentsin percentage by mass: 0.6-3% of an ashless anti-wear agent, 0.05-1% of an ashless metal passivator, 0.01-0.5% of an ashless antifoaming agent, 0.5-2% of an ashless antioxygen, and the balance of base oil used for supplementing to 100%. The ashless high-performance vacuum pump oil obtained through optimized combination of all optimal additives has excellent comprehensive performance, high limit vacuum degree, and long service life. The antioxygen and the base oil are optimized to establish a long-life cycle use system, and emission of waste oil is significantly reduced; and by optimizing theantifoaming agent, the base oil and the anti-wear agent, operation of a pump body is ensured, and the fault probability of the pump body is decreased.

Description

technical field [0001] The invention relates to the field of lubricating oil, in particular to an ashless high-performance vacuum pump oil. Background technique [0002] With the continuous development of modern industrial technology, the electric vacuum industry, vacuum metallurgy, vacuum coating, distillation industry, and food industry have increasingly stringent requirements for equipment. Products of Edwards, German Pusch, German Richelle and other companies. After the introduction of foreign vacuum equipment, vacuum oil used in conjunction with it is required. However, my country’s vacuum technology field started relatively late, and related technologies have not kept up with the pace of vacuum technology in Germany and Japan. , American West Iron and other brands, the price is high, so the market urgently needs domestic high-performance vacuum pump oil. Contents of the invention [0003] The technical problem to be solved by the invention is to provide a kind of a...
