Problems solved by technology

After oil stains appear on the metal surface, the traditional method is to wash and dry them with water-based cleaning agents. If an oxide layer appears, the workpiece often needs to be reworked for secondary sandblasting or cleaning with concentrated acid, which will inevitably lead to a great increase in cost; at present, domestic The process of removing surface oil stains on metal parts, many units use two processes: one is to use organic solvents such as gasoline, trichlorethylene, etc. to remove mineral oils; the other is to use sodium hydroxide, sodium carbonate, sodium phosphate, The mixture of silicic acid (water glass) mainly removes animal and vegetable oils
When this method uses organic toxic solvents to remove oil, it is difficult, costly, labor-intensive, and prone to accidents. The anti-rust period of traditional cleaning agents on the market is short, generally about one month

preparation example Construction

[0016] This embodiment also discloses a preparation method of the die-casting sandblasted aluminum alloy surface cleaning agent, which includes the following steps:

[0017] a. Preparation of the mixed bag: according to parts by weight, the brightener, rust inhibitor, film-forming agent, and other functional additives are mixed and fully stirred until uniform and transparent, to obtain a mixed bag;

[0018] b. Add the mixed bag to the solvent oil and stir again until it is uniform and transparent; a functional cleaning agent is prepared.

[0019] The invention also discloses a method for using the surface cleaning agent for die-casting sandblasting aluminum alloy. The finished metal workpiece of the casting is soaked in the multifunctional cleaning agent for 5-10 seconds; the soaking moment slightly swings to facilitate thorough cleaning and cleaning Short time and high efficiency.

Embodiment 1

[0022] The surface cleaning agent for die-casting sandblasted aluminum alloy of this embodiment includes the following components in parts by weight: 70 parts solvent oil, 5 parts brightener, 10 parts rust inhibitor, 5 parts film-forming agent, 10 parts masking agent Flavoring agent

[0023] In this embodiment, the solvent oil is D40, and other volatile solvent oils with similar physical and chemical properties are used instead of D40 solvent oil, which has no obvious impact on the performance of the product; the brightener is nonylphenol polyoxyethylene ether, which adopts physical and chemical properties Other similar brighteners have no obvious effect on the performance of the product; the dicarboxylic acid salt-based compound rust inhibitor with similar properties is the dicarboxylic acid triethanolamine salt-based compound, and other rust inhibitors commonly used in machining fluids are used Instead of dicarboxylic acid triethanolamine salt-based compound, there is no obviou...

Embodiment 2

[0030] The surface cleaning agent for die-casting sandblasted aluminum alloy of this embodiment includes the following components in parts by weight: 65 parts of solvent oil, 3 parts of brightener, 12 parts of rust inhibitor, 10 parts of film-forming agent, 9 parts of anti-corrosion Oxygen agent

[0031] In this example, the mineral spirit is D30, and other volatile mineral spirits with similar physical and chemical properties are used instead of D30 mineral spirits, which has no obvious effect on the performance of the product; the brightener is benzalacetone, and other brighteners with similar physical and chemical properties are used. It has no obvious effect on the performance of the product; the dicarboxylic acid salt-based compound rust inhibitor with similar properties is the dicarboxylic acid triethanolamine salt-based compound, and other rust inhibitors commonly used in machining fluids are used instead of dicarboxylic acid There is no obvious difference in the performan...

Abstract

The invention discloses a preparation method and a using method of a die-casting sandblasting aluminum alloy surface cleaning agent. The cleaning agent mainly comprises volatile solvent oil, a brightener, a preservative and a film-forming agent. The cleaning agent is convenient, safe and environment-friendly to use, has no pungent odor, is free of heavy metallic salt, is mainly used for die-casting metal, particularly die-casting sandblasting aluminum alloy surface preservative treatment, and exerts preservative and brightening effects on a metal surface. With the adoption of the cleaning agent, the surface reject rate of a workpiece can be reduced well; the reworking is reduced; and the trouble that sandblasting is required again due to surface finish is solved.

Description

Technical field [0001] The invention relates to the technical field of industrial cleaning, in particular to a die-casting sandblasted aluminum alloy surface cleaning agent that not only has a cleaning function, but also can protect metal surfaces and improve the aesthetics of workpieces, a preparation method and a use method. Background technique [0002] Die casting refers to a casting method in which molten alloy is filled into the mold cavity under high pressure and high speed conditions, and is cooled to form under high pressure. It is one of the most widely used and fastest developing metal hot forming process methods in the casting process. As an advanced non-ferrous alloy precision parts forming technology, die-casting meets the requirements of product complexity, precision, light weight, energy saving, and greenness in modern manufacturing, and its application fields are continuously expanding. Commonly used die-casting alloys include zinc alloy, aluminum alloy, magnesiu...
