Abstract
The invention discloses a cleaning agent for aluminum alloy, and a preparation method and application thereof. A cleaning agent for aluminum alloys, comprising the following components or a reaction product of the following components: softening water, antirust agent, defoamer, alkali number maintaining agent, surfactant, cleaning auxiliary agent, aluminum corrosion inhibitor and bactericide. The cleaning agent for aluminum alloy has the advantages of environmental protection and high oil washing rate, and can effectively prevent corrosion in the aluminum cleaning process and prevent machine tools from rusting.
Description
Technical Field
The invention relates to the field of metal processing, in particular to a cleaning agent for aluminum alloy, and a preparation method and application thereof.
Background
Aluminum is a silvery white reactive light metal and is ductile. The chemical property of the metal oxide film is active, and a layer of compact oxide film can be quickly formed in dry air, so that the metal is prevented from being continuously oxidized and corroded. Aluminum is easy to process, has strong durability, and has a superior weight-to-strength ratio, so it was first applied to the construction field. In the world today, aluminum is used in its broad field: in daily life, almost every household has aluminum foil used for cooking; in the construction field, door frames and window frames in houses and apartment blocks constructed may be made of aluminum; in the field of aircraft manufacturing, aluminum is an ideal material for manufacturing aircraft because of its low density and high strength; in the automobile manufacturing industry, the weight of the automobile body and parts made of metal aluminum can be reduced, so that the oil consumption is reduced, and the application of aluminum in the automobile manufacturing industry becomes more commercial prospect.
Unlike metals such as iron, steel, copper, etc., aluminum is an amphoteric metal that can react with not only acids but also bases. Meanwhile, the chemical property of the metal cleaning agent is active, so that the metal cleaning agent has high requirements on the metal cleaning agent used in the processing process.
CN108570680a discloses an aluminum cleaning agent with stable oil removal and simple process and a preparation method thereof, wherein the weight percentage of the formula is that A, stearic acid is 2-4%, silicone-ethylene glycol copolymer is 1-2%, propylene glycol methyl ether is 3-6%; B. 1-2% of triethanolamine and 26-41.8% of water; C. 11-13% of silicon dioxide and 0.2-1% of methanol cellulose ether; D. 30.2 to 55.8 percent of water. The patent prepares an aluminum cleaning agent, but the preparation method is more complicated and requires a larger number of blending kettles. Meanwhile, the production process needs to be heated to more than 80 ℃ and has high energy consumption.
CN106835169a discloses an aluminum cleaning agent and a preparation method thereof, which consists of the following raw materials: 2-6% of potassium hydroxide, 2-10% of glycerol butyl ether, 1-5% of sodium metasilicate, 1-5% of boric acid, 1-7% of sodium polyacrylate, 1-5% of sorbitol solution, 0.4-1.2% of sodium chloride, 0.1-0,5% of dimethyl siloxane, 1-8% of anionic surfactant, 1-8% of nonionic surfactant and the balance of water. The formula of the invention does not contain substances harmful to human bodies and the environment, such as phosphate, heavy metals and the like, has no pollution to the environment and is safe and reliable to use. However, the potassium hydroxide used in the formula is strong alkali, so that the danger of corrosion to workers in the production and use processes can be caused, and meanwhile, the rust inhibitor is absent in the formula, so that the corrosion of production equipment can be caused.
CN106947979a discloses a cleaning agent for magnesium-aluminum alloy, which comprises weakly alkaline substances, a surfactant, a cleaning auxiliary agent, a corrosion inhibitor, an environment-friendly solvent and water. The surfactant comprises easily purchased alcohol ether and alkyl glycoside, has good cleaning effect, is slightly alkaline, has low corrosiveness to magnesium-aluminum alloy, and is easy to biodegrade. However, the formulation contains diethanolamine, a material which is listed as a limiting material for metal working fluids and presents a certain risk to both humans and the environment.
In the prior art, the water-based metal cleaning agent needs to be used as a raw material which is corrosive or not friendly to human bodies and environment, or has higher requirements on production equipment. Therefore, developing a cleaning agent which has mild production conditions, no corrosive raw materials and is special for cleaning aluminum alloy and is friendly to human bodies and environment has important significance.
Disclosure of Invention
One of the technical problems to be solved by the invention is that the existing cleaning agent contains raw materials which are strong in corrosiveness and harmful to human bodies and environment. The invention provides a novel water-based cleaning agent for cleaning aluminum alloy, which has the advantages of environmental protection and high oil washing rate, and can effectively prevent corrosion in the aluminum cleaning process and prevent machine tools from rusting.
The second technical problem to be solved by the invention is to provide a preparation method of the cleaning agent for aluminum alloy.

Comparative examples 7 and 8 satisfy the requirements of rust resistance, corrosion resistance and oil washing ability, but have problems of foam accumulation or odor generation during use.
It can be seen that the water-based cleaning agent special for aluminum alloy in examples 1-9, 12-13, 15, 18-19 and 21-22, which have the dosages within the dosage range defined by the invention, has mild process conditions in the preparation process, does not contain additive such as diethanolamine which is limited in use, has excellent aluminum corrosion inhibition performance and higher oil washing capability, and has certain antirust performance. The cleaning device can ensure that the equipment is not threatened by rust while meeting the cleaning operation requirement of the aluminum alloy workpiece, has good technical effect, and can be used in the application of the aluminum alloy cleaning process. When the amounts of the substances used in examples 10 to 11, 14, 16 to 17, 20, and 23 to 24 were out of the range defined in the present invention, there were problems of poor rust inhibitive performance, corrosion to aluminum, degradation of corrosion inhibitive performance of aluminum, and deterioration of cleaning ability, and it was found that the substances and the specific amounts of the substances used in the present invention had synergistic effects and had better effects.
What has been described above is merely a preferred example of the present invention. It should be noted that other equivalent modifications and improvements will occur to those skilled in the art, and are intended to be within the scope of the present invention, as a matter of common general knowledge in the art, in light of the technical teaching provided by the present invention.
