Water-based complete-synthesis cutting liquid for steel grit die-casting aluminum material as well as preparation method and using method thereof

Abstract

The invention discloses water-based complete-synthesis cutting liquid for a steel grit die-casting aluminum material as well as a preparation method and a using method thereof. The cutting liquid comprises the following raw materials: a benzotriazole derivative agent, a non-ionic emulsifier, a water-based extreme-pressure lubricant, boric acid, glycerol, triethanolamine, a dicarboxylate-based composite antirust agent, an n-caprylic acid coupling agent, a hard water resistant agent, a defoaming agent and the balance of pure water, wherein the total amount is 100 percent. The cutting liquid prepared by the method can be used after being diluted by adding water according to the ratio of the cutting liquid to the water of 1:(10-30); the diluent has excellent lubricating property, antirust property and settling property, and has a good protective effect special for steel grit. All the indexes of the 5% diluent reach or exceed the related indexes of GB6144-2010. The cutting liquid has long service life, does not contain harmful substances such as formaldehyde and nitrite, reduces emission, avoids environmental pollution and saves economic cost.

Description

technical field [0001] The invention relates to a cutting fluid for machining, a preparation method and a use method thereof, in particular to a water-based fully synthetic cutting fluid for steel sand die-casting aluminum materials, a preparation method and a use method thereof. Background technique [0002] Sand blasting is to use compressed air to spray sand directly on the surface of the workpiece, and use the strong collision of the sand to remove the surface defects and dirt of the workpiece to achieve the purpose of cleaning and modification. Among the current aluminum die castings, sand blasting is the most widely used post-processing process for those with strict appearance requirements. However, the die-casting aluminum after sandblasting, when cutting, using traditional water-based aluminum cutting fluid, the surface of the workpiece is prone to oxidation such as blackening, darkening and long white hair, resulting in unqualified or even scrapped products.
