Problems solved by technology

Although these rusts can be cleaned with existing cleaning agents, the existing cleaning agents have the following problems: 1. The oil stains on the surface of steel products after cleaning are basically removed, but a large number of fine particles such as dust and iron powder will remain; 2. For Steel products that have been rusted before cleaning have no rust removal effect; 3. Steel products will rust in a short period of time after cleaning

Abstract

The invention discloses a multifunctional alkaline cleaning agent. The raw material composition of the multifunctional alkaline cleaning agent comprises, by weight, 2-5 parts of potassium carbonate, 2-5 parts of sodium gluconate, 0.5-5 parts of cocoanut fatty acid diethanolamide, 2-5 parts of sodium dodecylbenzene sulfonate, 5-10 parts of monoethanolamine borate, 5-10 parts of dipropylene glycol methyl ether, 5-10 parts of penetrants, 0.5-5 parts of solubilizers, and 10-20 parts of HEDP-4Na, and water is used for complementing to 100 parts. A steel product treated through the cleaning agent has the high surface cleanliness, no oil dirt residue, and no scrap iron, rust deposit and dust particle residue are achieved, the steel product after being cleaned can still meet interprocess rust prevention, the surface brightness of the steel product can be increased, the using cycle is long, the using concentration is low, and the rust prevention period is up to 10-20 days; the safe and environmental protection effects are achieved, the multifunctional alkaline cleaning agent is harmless to a human body, raw materials are wide in sources and easy to obtain, the cost is low, and the multifunctional alkaline cleaning agent is suitable for mass production.

Description

technical field [0001] The invention belongs to the field of chemical cleaning and antirust, and relates to cleaning and antirust agents, in particular to a multifunctional alkaline cleaning agent and a preparation method thereof. The multifunctional alkaline cleaning agent can be used for dust removal and oil removal on the surface of steel products , Rust removal, anti-rust treatment. Background technique [0002] Steel is the earliest and most widely used basic material in modern industry. During various processing processes of steel products such as cutting and grinding, certain dirt such as oil, iron powder, and iron filings will remain. These dirt are closely attached to the metal through physical adsorption or electrostatic adsorption, which is difficult to remove. At the same time, the chemical properties of steel are relatively active, and when exposed to the air for a long time, it will undergo an oxidation reaction with oxygen, or be eroded by oxygen in water to...
