Problems solved by technology

[0005] After decontamination, the oil stain is dispersed in the form of fine particles in the cleaning agent with a high content, and forms a stable emulsion, which not only reduces the cleaning and reuse ability of the cleaning agent, but also brings pollution to the discharge of waste liquid. great pressure on environmental protection

Embodiment 1

[0024] Add 2 g of sodium nitrilotriacetate, 4 g of sodium benzoate, and 6 g of trisodium phosphate into 57 g of water one by one. The number of carbon atoms is 7g of alkyl dimethyl aminoacetic acid betaine 7g, while adding, stir, and finally add 20g of water, until the above two components are completely dissolved and even, to obtain the required 100g of this anti-emulsifying water base metal cleaner.

Embodiment 2

[0026] Add 2g of sodium citrate, 4g of sodium nitrite, and 6g of sodium metasilicate to 56g of water one by one. Add 6g of betaine, stir while adding, and finally add 20g of water until the above two components are completely dissolved and evenly, to obtain the required 100g of this anti-emulsifying water-based metal cleaning agent.

Embodiment 3

[0028] Add 2g of tetrasodium edetate, 4g of long carbon chain carboxylic acid amine with 10 carbon atoms in long carbon chain, and 6g of sodium carbonate into 58g of water one by one. After dissolving evenly, slowly add the addition of ethylene oxide. Number is 9 fatty alcohol polyoxyethylene ether ammonium sulfate 5g, cocamidopropyl betaine 5g, stirs while adding, finally adds the water of 20g, gets final product until above-mentioned two components dissolve completely, obtains required 100g of this anti-emulsifying water-based metal cleaner.

Abstract

The invention relates to an anti-emulsification water-soluble metal washing agent. Every 100 parts of the anti-emulsification water-soluble metal washing agent include the following components according to parts by weight: 3-7 non-ionic surfactant, 3-7 bi-ion active agent, 1-5 chelator, 1-5 rust preventive, 5-10 inorganic builder and the balance water, wherein the non-ionic surfactant is any one of fatty amine polyoxypropylene ether, alkylphenol ether and fatty amine polyoxyethylene alkyl ether ammonium sulfate, the bi-ion active agent is any one of alkyl dimethylin acetic acid betaine, lauramidopropyl betaine and cocamidopropyl betaine, the chelator is any one of sodium citrate, ethylenediaminetetraacetic acid tetrasodium salt and nitrilotriacetic acid sodium salt, the rust preventive is any one of sodium borate, sodium nitrite, sodium benzoate and long carbon chain carboxylic acid amine, and the inorganic builder is any one of trisodium phosphate, sodium metasillcate, sodium carbonate, sodium bicarbonate and sodium hydroxide. The anti-emulsification water-soluble metal washing agent has the advantage of higher cleaning capacity and reutilization capacity.

Description

technical field [0001] The present invention relates to an anti-emulsification type water-based metal cleaner for cleaning metal. Background technique [0002] During the manufacturing and processing of mechanical parts, a large amount of oily medium is often used for lubrication, cooling or anti-rust treatment. These oily media include cutting oil, quenching oil, rolling oil, anti-rust oil, etc. In order to ensure the processing quality of parts, after the completion of each processing procedure, the above-mentioned medium should basically be cleaned, and water-based metal cleaning agents are widely used. [0003] When cleaning, the alkali salts, surfactants and oil stains in the cleaning agent react chemically or physically, and the decontamination effect is realized by means of the wetting, penetrating, emulsifying, dispersing, and solubilizing properties of the surfactant. [0004] The decontamination process can be roughly divided into the following two steps: 1. The c...
