Problems solved by technology

[0006] In recent years, the metal cleaning agent industry has achieved rapid development, and there are many types, but the solid metal cleaning agent has poor solubility, and the cleaning effect at room temperature is not ideal. It needs to be cleaned at elevated temperatures, and this type of metal cleaning agent is often alkaline Strong, easy to cause damage to the metal surface
At present, many water-based metal cleaning agents have come out, but there are still many problems that need to be improved in terms of cleaning temperature, anti-corrosion, anti-rust, high efficiency and environmental protection, and cannot completely replace solvent-based metal cleaning agents. limit

Abstract

The invention provides residual oil cleaning agent for metallic equipment and a preparation method thereof. The residual oil cleaning agent comprises the following ingredients: octylphenol polyoxyethylene ether, polyoxyethylene fatty alcohol sodium sulfate, sodium polyacrylate, polyphosphate, sodium nitrilotriacetate, tributyl phosphate, hexamethylene tetramine, benzyl trimethyl ammonium chloride, sulfonamic acid, ethylene glycol butyl ester, dimethylaminoethyl acrylate, allyl trimethylammonium chloride, a corrosion inhibitor and deionized water. The preparation method comprises the following steps: adding the octylphenol polyoxyethylene ether, polyoxyethylene fatty alcohol sodium sulfate, sodium polyacrylate and polyphosphate into the deionized water to obtain a mixture I; mixing the sodium nitrilotriacetate, tributyl phosphate, hexamethylene tetramine, benzyltrimethylammonium chloride, sulfonamic acid and the ethylene glycol butyl ester to obtain a mixture II; adding the rest of the ingredients into the compound of the mixture I and the mixture II to obtain the residual oil cleaning agent. The residual oil cleaning agent is a low-foaming type cleaning agent, and is excellent in cleaning capacity, rustproof capacity, anti-corrosion performance and high-low temperature stability.

Description

technical field [0001] The invention belongs to the technical field of metal cleaning agents, and in particular relates to a residual oil cleaning agent for metal equipment and a preparation method thereof. Background technique [0002] In modern production and life, metals are widely used in various important sectors such as construction, machinery, metallurgy, electronics, packaging, automobiles and high technology. They are not only functional materials but also structural materials, penetrating into various fields. [0003] In industrial production, even if metal parts do not undergo post-processing such as plating and other surface treatments, oil stains must be removed at a certain stage of production. After a certain period of operation in oil and gas transportation pipelines, fuel nozzles, and oil refining units, a certain amount of residual oil and dirt will often accumulate. It is easy to cause equipment accidents and safety accidents, which will bury hidden dange...
