Aluminum alloy plate water-soluble stamping oil

Abstract

The invention relates to an aluminum alloy plate water-soluble stamping oil, which comprises the following raw material components by weight: 3-8% of pentaerythritol monooleate, 2-5% of an extreme pressure agent, 5-12% of sodium petroleum sulfonate, 4-10% of an emulsifier, 0.5-4% of an anti-rust agent, 0.5-2.0% of a non-ionic surfactant, 1-5% of fatty alcohol polyoxyethylene ether, 0.2-1.5% of anamine neutralized phosphate aluminum corrosion inhibitor, 0.03-0.1% of a defoaming agent, 0.5-1.5% of preservative MBM, and the balance of base oil. According to the present invention, the aluminum alloy plate water-soluble stamping oil is finely blended from the highly-refined paraffin base oil and the additives such as the emulsifier, the extreme pressure agent, the synthetic ester oily agent, the surfactant, the defoaming agent, the bactericide, the anti-rust agent and the like, has advantages of low odor, excellent extreme pressure property, excellent corrosion resistance and excellent lubricity, and is suitable for the stamping, the drawing, the punching and other processing processes of aluminum alloy plates.

Description

technical field [0001] The invention belongs to the field of chemical products, in particular to a water-soluble stamping oil for aluminum alloy plates. Background technique [0002] With the increasing contradiction between energy supply and social demand, major automobile manufacturers in the world have increased their efforts in research and development of energy-saving and consumption-reducing products. Aluminum alloy plates are light in weight and high in specific strength, and are increasingly becoming the favored object of automobile panels. The light weight of automobile panels has become one of the most direct measures to solve this contradiction. However, the aluminum alloy plate has poor plasticity, and the new metal formed during forming has strong surface activity, is easy to adhere to the mold, and is easily oxidized into a hard and brittle wear-resistant layer. This is closely related to the friction and lubrication state of the aluminum alloy sheet during fo...

Problems solved by technology

[0003] At present, there are very few water-soluble stamping oils for aluminum alloy sheets in the domestic market, and there are problems such as the surface of the workpiece is easily corroded and discolored after stamping is completed, and the color is dark.
