Description

Technical Field

[0001] The present invention relates to the field of chemical industry, and in particular to a normal-temperature immersion type butter cleaning agent and a preparation method thereof. Background Art

[0002] Cleaning mechanical equipment is an essential process during the processing, assembly, storage, and maintenance of these components. Grease and oil deposits adhering to mechanical surfaces can cause and accelerate metal corrosion, reduce product quality, and shorten service life. In the cleaning industry, professionals are required to consider not only cleaning performance but also safety and environmental friendliness when selecting cleaning agents, minimizing environmental pollution and preventing the agents from harming the health of operators. Currently, strong alkaline cleaning agents and organic solvents (such as petroleum solvents and halogenated hydrocarbon solvents) are still widely used for cleaning in industrial production. Strong alkaline cleaning agents, whose main ingredients are NaOH, Na2CO3, Na2SiO3, Na3PO4, and STPP, have poor cleaning performance and can easily rust parts after cleaning. They are typically used to clean mild oil stains and inorganic salts from ferrous metal surfaces. While solvent cleaners have strong cleaning capabilities and can easily remove grease stains from metal surfaces, most are flammable and volatile, wasting significant energy and causing environmental pollution. They are also highly irritating to the human central nervous system, and long-term exposure can cause neurasthenia, dry skin, and other illnesses. Water-based cleaners, which are primarily based on surfactants, produce large amounts of foam that is difficult to remove and hinders subsequent operations.

[0003] Chinese patent application number CN201811542408.6 discloses a metal surface cleaning agent for heavy oil stains. The cleaning agent is prepared from the following raw materials in percentage by weight: 15%-25% emulsifier; 4%-10% penetrant; 6%-12% oil softener; 1%-4% alkaline additive; 0.2-2% corrosion inhibitor; and the balance is water. The metal surface cleaning agent of the present invention has a rational formula and is effective in cleaning heavy oil stains such as heavy motor oil and butter on metal surfaces. It has good performance, strong degreasing performance, low production cost, no toxic side effects, and is phosphorus-free, pollution-free, and residue-free, meeting environmentally friendly discharge requirements for the three wastes. Chinese patent application number CN201610213083.1 discloses a metal cleaning agent comprising the following components: an ultra-low interfacial tension surfactant, lactic acid, an emulsifier, an acidic cleaning agent, an acidic corrosion inhibitor, a penetrant, coconut oil fatty acid diethanolamide, isothiazolinone, tea oil and tea seed powder, an organic solvent, and sorbitol. The present invention provides a weak acid cleaning agent that has excellent cleaning effectiveness and is foam-free. It can easily remove thick oil stains such as animal oil, mineral oil, heavy engine oil, and butter from metal surfaces, forming a continuous water film on the workpiece after cleaning. It is phosphorus-free, pollution-free, and residue-free, meeting environmental requirements for the discharge of three wastes. It also has strong solubility, will not delaminate or precipitate after long-term storage, and is a highly stable metal cleaning agent. While these inventions offer excellent cleaning effectiveness and are pollution-free and residue-free, they lack a strong emulsifying effect on butter and oil stains, resulting in a short emulsification time and a long cleaning process. Summary of the Invention

[0004] In response to the deficiencies in the prior art, the present invention provides a room-temperature immersion butter cleaner and a preparation method thereof. The agent adopts unique compound raw materials, has excellent emulsification and dispersion effects on butter, utilizes the high content of imported pearl alkali to achieve a certain saponification effect, and at the same time assists the chelating agent in chelating and separating metal ions, thereby being able to clean butter and oil stains at room temperature.
