No-clean copper-aluminum sheet stamping oil

Abstract

The invention provides no-clean copper-aluminum sheet stamping oil, and relates to the technical field of stamping oil compositions.On the basis of preparation of traditional no-clean copper-aluminum sheet stamping oil, by arranging an antistatic additive, the conductivity and moisture absorption performance of the stamping oil can be improved, electrostatic leakage can be accelerated, electrostatic aggregation can be reduced, and electrostatic hazards can be eliminated; compared with the prior art, the stamping oil composition provided by the invention has the advantages that the stamping oil composition adopts the isomerized alkane solvents, so that the stamping oil composition is high in purity, extremely low in residual quantity, more than 99.8% in volatilizable solvent base oil and better in environmental protection property as compared with a common alkane solvent, and the situation that the stamping oil generates higher voltage in a high-speed flowing process is avoided, so that the use safety of the stamping oil is ensured. By selecting the lubricant with better extreme pressure property, the stamping oil has excellent lubricity, and meanwhile, under the action of additives such as the metal deactivator, the stamping oil also has excellent metal protectiveness.

Description

technical field [0001] The invention relates to the technical field of punching oil compositions, in particular to a no-cleaning punching oil for copper and aluminum flakes. Background technique [0002] Stamping oil is a metal processing oil formulated from vulcanized lard as the main agent, adding various additives such as refined oily agents and rust inhibitors. It is especially suitable for high-intensity operations such as punching, stamping, tapping, and tapping. At the same time, it is also very suitable for plastic forming processing, has good lubricity and extreme pressure, and has good protection performance for molds. [0003] At present, there are many oils used for stamping copper and aluminum parts of electronic products on the market. The common problem of these oils is that there will always be a small amount of oil components on the surface of the workpiece after stamping. At this time, people need to add additional cleaning.

[0003] At present, there are many oils used for stamping copper and aluminum parts of electronic products on the market. The common problem of these oils is that there will always be a small amount of oil components on the surface of the workpiece after stamping. At this time, people need to add additional cleaning. Equipment and technology can completely remove the oil, the cleaning equipment used increases the production cost, and the used cleaning agent is also likely to cause environmental pollution, and in the process of using the stamping oil, the faster the oil flow rate, the more intense the friction, The higher the static voltage is, at the same time, in a dry air environment, static electricity is not easy to eliminate from the air, which will also lead to an increase in voltage. When the oil contains water during transmission, the voltage generated by the oil is several times higher than that without water. times to dozens of times, although people currently eliminate static electricity by grounding the equipment, there are still some hidden dangers of static electricity, which reduces the safety of stamping oil
