Problems solved by technology

However, lubricating oil compositions used for a long time tend to cause disadvantages such as degradation of performance due to oxidation and precipitation of sludge accompanying oxidation.
The precipitated sludge may cause, for example, damage to the bearing due to adhesion to the bearing of the rotating body and heat generation, clogging of the filter installed in the circulation line, malfunction of the control system due to accumulation on the control valve, etc. question

Abstract

The invention discloses a high anti-oxidation minimal lubrication cutting oil and its preparation method and application, comprising the following components in parts by weight: 75-95 parts of base oil; 1-6 parts of antioxidant; 1 part of spreading agent -3 parts; 1-3 parts of extreme pressure antiwear agent; 0.5-1.5 parts of anti-fog agent; 1-2 parts of rust inhibitor; wherein, the base oil is a mixture of alkane oil and additives, and the antioxidant consists of It is compounded by shielding phenolic antioxidant, aromatic amine antioxidant and phenolic amine antioxidant. The cutting oil uses a specific antioxidant, and realizes the long-term recycling of the cutting oil through the mutual synergistic effect of the components in the cutting oil with a specific ratio. Compared with traditional cutting oils, the MQL cutting oil of the present invention not only has excellent oxidation resistance, but also maintains good oxidation stability even in long-term high and low temperature environments, has excellent service life, and is environmentally friendly , the preparation is simple, and industrialized production can be realized.

Description

technical field [0001] The invention relates to the technical field of lubricating oil, and more specifically, relates to a high-oxidation-resistant micro-lubricating cutting oil and a preparation method and application thereof. Background technique [0002] Lubricating oil is a liquid or semi-solid lubricant used in various types of automobiles and mechanical equipment to reduce friction and protect machinery and processed parts. It mainly plays the role of lubrication, auxiliary cooling, rust prevention and cleaning. However, a lubricating oil composition used for a long time tends to cause disadvantages such as degradation of performance due to oxidation, precipitation of sludge accompanying oxidation, and the like. The precipitated sludge may cause, for example, damage to the bearing due to adhesion to the bearing of the rotating body and heat generation, clogging of the filter installed in the circulation line, malfunction of the control system due to accumulation on th...
