Problems solved by technology

[0002] After the parts are processed by machining such as cutting and grinding, a large amount of iron filings, iron powder, oil stains, etc. will remain. These dirt are closely attached to the parts by physical adsorption or electrostatic adsorption, which is difficult to remove
Although the existing cleaning agent can be used for cleaning, the existing cleaning agent has the following problems: 1. After cleaning, the oil on the surface of the metal parts is basically removed, but a large amount of fine particles such as iron powder remain; 2. Some residues are caused by the cleaning agent. 3. Rust in a short period of time after cleaning
The main reason for the above problems is that most of the existing metal cleaning agents are cleaning agents with inorganic substances and hydrophilic surfactants as the main components. Very weak and does not meet the cleaning requirements

Embodiment 1

[0026] A kind of deashing cleaning antirust agent, its raw material composition, concentration and weight percent scope are respectively:

[0027] Tetrasodium edetate: content 99% ratio 8%

[0028] Sodium polyacrylate: content 30% ratio 3%

[0029] Propylene glycol methyl ether: content 95% ratio 5%

[0030] Isomerized alcohol ether: content 60% ratio 6%

[0031] AEO-3: content 99% ratio 1.5%

[0032] Fungicide: content 90% ratio 1%

[0033] Water: Mixing ratio 75.5%

[0034] Its preparation method is as follows:

[0035] (1) Add 50kg of water into the reaction kettle, add tetrasodium ethylenediaminetetraacetic acid at 40°C, and stir to dissolve it.

[0036] (2) Keep the temperature at 40°C, add AEO-3 while stirring, and stir for 45 minutes until uniform;

[0037] (3) After the temperature drops below 30°C, add propylene glycol methyl ether, sodium polyacrylate, and isomeric alcohol ether, and stir for 25 minutes until they are uniformly dissolved;

[0038] (4) Slowly ...

Abstract

The invention relates to a dusting cleaning antirusting agent and a preparation method thereof. The dusting cleaning antirusting agent comprises the following components in percentage by weight: 4.5 to 10 percent of tetrasodium ethylenediamine tetraacetate, 1 to 4.5 percent of sodium polyacrylate, 2.5 to 7.5 percent of heterogeneous alcohol ether, 0.8 to 3 percent of fatty alcohol-polyoxyethyleneether (AEO)-3, 2.5 to 12 percent of propylene glycol monomethyl ether, 0.8 to 3 percent of triazine bacteriacide and the balance of water. The dusting cleaning antirusting agent is suitable for spraying and ultrasonic cleaning; parts processed by the dusting cleaning antirusting agent are not needed to be rinsed and are high in cleanness, the surfaces of the parts do not have granule residues andwhite dirt residues, and the brightness of the parts can be increased; and the dusting cleaning antirusting agent has long service life and low concentration, and the antirusting period is 5 to 10 days. The dusting cleaning antirusting agent is safe, environment-friendly and low in cost, made of widely and readily available raw material, and is suitable for large-scale production.

Description

technical field [0001] The invention relates to the fields of chemical cleaning and antirust, and relates to an antirust agent, in particular to an antirust agent for ash removal and cleaning with excellent ash removal performance and a preparation method thereof. Background technique [0002] After the parts are processed by machining such as cutting and grinding, a large amount of iron filings, iron powder, oil stains, etc. will remain. These dirt are closely attached to the parts by physical adsorption or electrostatic adsorption, which is difficult to remove. Although the existing cleaning agent can be used for cleaning, the existing cleaning agent has the following problems: 1. After cleaning, the oil on the surface of the metal parts is basically removed, but a large amount of fine particles such as iron powder remain; 2. Some residues are caused by the cleaning agent. 3.
