The market development of the current automobile industry tends to the production of new energy engines and accessories thereof by mechanical manufacturing companies, and as an emerging industry with upward trend, the delivery requirements of customers on the engines and accessories thereof are obviously improved, in particular to the surface cleanliness and the neatness of aluminum alloy shells. In order to remove burrs on the shell and thoroughly remove surface metal particles, nonmetallic particles, fibers and the like, most manufacturers use ultrahigh pressure spraying equipment, and the requirements for cleaning agents are comprehensively as follows: 1. the product has no foam under the spray pressure of 20-30 Mpa; 2. the product has aluminum corrosion resistance and is suitable for cleaning aluminum alloy; 3. the cleanliness requirement is that the longest fiber size is less than or equal to 4000 mu m, the maximum metal particle size is less than or equal to 600 mu m, and the maximum nonmetal particle size is less than or equal to 1000 mu m; 4. the product has antibacterial property, rust resistance and corrosion resistance; 5. the surface of the workpiece has no obvious residue after cleaning;
The existing high-pressure spray cleaning agent is mixed with emulsified oil stains which are easy to foam in the previous working procedure after being used for a period of time, and the low-foam surface active foam inhibition capability of the cleaning agent is insufficient for inhibiting oil stain foam, so that the working fluid foam is increased, and the use environment is polluted. The low-foam surface activity is poor in cleaning effect due to weak emulsifying, penetrating and wetting capabilities, a certain amount of inorganic salt cleaning auxiliary agent is generally added for improving the cleaning capability, and the inorganic salt can cause obvious white residues on the surface of a workpiece after cleaning, so that the appearance cleanliness is affected.
In addition to the foam requirement and the cleaning force requirement under the spray pressure of 30Mpa, the aluminum corrosion resistance of the cleaning agent required to be simultaneously possessed by the ultra-high pressure spray cleaning agent is often easily ignored. The aluminum corrosion inhibitors added in the aluminum part cleaning agent in the current market are silicon-containing compounds (such as silane, silicate and the like) and phosphorus-containing compounds (organic phosphonic acid, phosphate and the like), and silicon elements have great influence on the uniformity of the surface oxidation film of certain aluminum alloys because silicon is not dissolved in the oxidation process, other alloy elements are dissolved in the solution, and the silicon prevents the oxidation of aluminum in the alloy, so that the surface silicon-containing cast aluminum alloy anodic oxide film is uneven and incomplete. Because of environmental protection pressure, a large part of manufacturers require that the cleaning agent cannot contain phosphorus, so that the use of the phosphorus-containing aluminum corrosion inhibitor is greatly limited.

The composition table is shown in table 7 below:
Table 7 is a composition table of the cleaning agent in example 7
The cleaning agents obtained in examples 1 to 7 were subjected to the following experimental tests:
table 8 shows a plurality of sets of example test data
/>
Note that: the oil stain mixed with defoaming property is an emulsified oil groove liquid obtained from a cutting machining center of an automobile engine manufacturing plant.
The data in table 8 can be analyzed: the formulation of the embodiment 1-the embodiment 7 is used for preparing uniform liquid with strong stability and weak alkalinity, and the appearance and the stability of the uniform liquid are improved mainly by the acid-base reaction of organic carboxylic acid and water-soluble organic alcohol amine and the addition of aluminum corrosion inhibitor, surfactant, foam inhibitor and bacteriostat; various indexes of the foam-removing agent are detected through a GB/T35759-2017 experimental method, compared with the foam removing performance of the embodiment 3 without the oil stain, the foam-removing agent has good foam removing performance, and the foam-removing agent can be regarded as being free of foam; after the oil stains are added, the defoaming performance of the whole case is reduced, but the descending trend of the embodiment 2 is obvious; the corrosion performance test results show that LY12 aluminum of example 2, example 4, example 6 and example 7 respectively exhibit different degrees of corrosion, and the rust inhibitive performance test results show that Z30 cast iron of example 4 and example 5 are corroded, and LY12 aluminum of example 2, example 4, example 6 and example 7 are corroded; the rinse performance and high and low temperature stability of the 7 examples were acceptable as standard.
Comparing the indexes of the examples 1 to 7, wherein each index of the example 1 is qualified, and the examples 2 to 7 have different performance defects; the cleaning effect of analysis example 3 is best, but the defoaming performance without adding greasy dirt is poor, and the analysis reason is that the surfactant is matched with the foam inhibitor C12-C14 ethoxypropoxylated tertiary butylamine, the foam inhibition effect of the C12-C14 ethoxypropoxylated tertiary butylamine on EO/PO polyether is obvious, and the foam inhibition effect on fatty alcohol polyoxyethylene ether is poorer;
Example 2 has poor defoaming property after adding oil stains, and the analysis reasons are probably that the chelating property of sodium citrate is good, the oil stains are complexly dispersed, and the foam is raised due to fatty acid and polyether type easily foaming substances in the oil stains;
LY12 aluminum of example 2, example 4, example 6 and example 7 exhibited different degrees of corrosion and rust, respectively, and sodium citrate was used as an aluminum corrosion inhibitor in comparative analysis example 2, which was weaker than citric acid; the organic carboxylic acid used in example 4 is a combination of an amide carboxylic acid, boric acid and isooctanoic acid, and compared with a combination of a C11-C14 ternary mixed acid, boric acid and isooctanoic acid, the former has deeper corrosion degree to aluminum; the triethanolamine, the methyldiethylamine and the diethanolamine used in the example 6 are compounded, the triethanolamine, the isopropanolamine and the diethanolamine are compounded in the example 7, the pH values of the two examples are higher, and the corrosion degree to aluminum is obvious;
the Z30 cast iron of example 4 and example 5 is rusted, the comparative analysis is related to the compounding selection of organic carboxylic acid, and the C11-C14 ternary mixed acid, boric acid and isooctanoic acid are compounded, so that the use effect is optimal.
By comparing the examples 1-7, the experimental effects of defoaming property, corrosiveness and rust resistance of the analysis example 1 are better, the cleaning capacity is slightly poorer than that of the example 3, but the defoaming property under the high-pressure spraying use condition is comprehensively considered, the example 1 is finally selected, the carboxylate rust inhibitor obtained in the example 1 has a certain rust-proof effect on cleaning equipment through the acid-base fusion reaction of C11-C14 ternary mixed acid, boric acid and isooctanoic acid with triethanolamine, methyl diethylamine and diglycolamine, then the citric acid is compounded to serve as an aluminum corrosion inhibitor, the triazole is a copper corrosion inhibitor, and the nonferrous metal has excellent corrosion resistance, and the conventional EO/PO polyether and the C12-14 ethoxypropoxylated tertiary butylamine are compounded, so that the product has excellent cleaning capacity and defoaming property under the high-pressure spraying condition, and the benzisoxazolinone and morpholine derivatives are used for controlling bacterial growth.
In the embodiment 1, the on-site trial of the engine manufacturer of the new energy automobile is carried out for nearly one year, the cleaning equipment is a single-spindle tool-changing type numerical control high-pressure cleaning center produced by Shanghai Hefeng precision machinery limited company, the highest spraying pressure of the equipment is 50Mpa, the using pressure is controlled by an intelligent pressure regulating system, the on-line trial pressure is 20-30Mpa, and the cleaning pressure is regulated according to different cleaning positions of workpieces; the trial results meet the following requirements: 1. the product has no foam under the spray pressure of 20-30 Mpa; 2. the product has aluminum corrosion resistance, the aluminum alloy box body has no corrosion phenomenon in the cleaning process and the placing process after cleaning, and the aluminum alloy box body is suitable for cleaning aluminum alloy; 3. the cleanliness of the workpiece meets the requirements: the longest fiber size is less than or equal to 4000 mu m, the maximum metal particle size is less than or equal to 600 mu m, and the maximum nonmetal particle size is less than or equal to 1000 mu m; 4. the product has antibacterial property, the cleaning agent has a tank replacement period of 2 months, the use temperature is 30-40 ℃, and the bacteria breeding phenomenon of the tank liquor does not occur; the product has rust resistance, and the cleaning equipment does not have corrosion phenomenon during use; 5. the surface of the workpiece has no obvious residue after cleaning;
The practical application feasibility of the scheme can be finally determined through laboratory detection and on-site application, and the scheme has a certain antirust effect on cleaning equipment through the acid-base fusion reaction of C11-C14 ternary mixed acid, boric acid and isooctanoic acid, triethanolamine, methyldiethylamine and diglycolamine, and the obtained carboxylate antirust agent has an excellent anticorrosion capacity on nonferrous metals by compounding citric acid as an aluminum corrosion inhibitor and triazole as a copper corrosion inhibitor.
In addition, in the scheme, in order to ensure the cleaning force of the cleaning agent, a conventional polyether surfactant is used, and the C12-C14 ethoxyl propoxylated tertiary butylamine serving as a foam inhibitor is compounded, so that the foam requirement under the spraying pressure of 30Mpa can be met.
In the scheme, the full organic chemical components are adopted, and dangerous chemicals harmful to human bodies or environments, such as nitrite, sodium metasilicate, phosphorus-containing chemical substances and the like, are not contained, so that the cleaning agent provided by the scheme is more environment-friendly, is friendly to human bodies and environment, and is more suitable for the environment-friendly requirement in the current chemical manufacturing environment.
