Trace lubricating oil and preparation method thereof

Abstract

The invention provides trace lubricating oil and a preparation method thereof, and relates to the technical field of lubricants, and the trace lubricating oil comprises the following components in parts by weight: 5-10 parts of an extreme pressure agent, 3-5 parts of vulcanized lard, 7-10 parts of super-alkali calcium sulfonate, 3-5 parts of an anti-wear agent, 0.3-0.6 part of an antioxidant additive, 0.5-0.6 part of a clearing agent, 0.02-0.1 part of a corrosion inhibitor, and the balance of non-drying oil. According to the trace lubricating oil, the extreme pressure agent is adopted as the additive, the additive contains high-activity sulfur and can provide good extreme pressure property, the super-base-number calcium sulfonate can provide the extreme pressure property and also has excellent anti-rust property, so that the trace lubricating oil has excellent anti-rust property, and finally through the added clearing agent, the trace lubricating oil has excellent anti-rust property. According to the present invention, the added corrosion inhibitor can effectively improve the detergency and the dispersibility, can strongly neutralize the corrosion of corrosive acid, can further improve the anti-rust performance, and in conclusion, has characteristics of high practicality and prominent creativity.

Description

technical field

[0001] The invention relates to the technical field of lubricants, in particular to a micro-quantity lubricating oil and a preparation method thereof. Background technique

[0002] Minimal quantity lubrication is also called minimum quantity lubrication. It is a kind of lubrication method for metal processing. Its semi-dry cutting refers to the gasification of compressed gas and a very small amount of lubricating oil to form nano-scale droplets, which are sprayed into the processing area for further processing. A cutting processing method for effective lubrication, the viscosity of the micro-quantity lubricant is lower, and the oil mist is smaller, which can eliminate the stress of the tool and the workpiece due to temperature changes, and the cooling effect is outstanding.
