Technical Field
The invention relates to the field of cleaning agents in the mechanical industry, in particular to a phosphorus-free antirust metal cleaning agent and a preparation method thereof.
Background
At present, cleaning agents used for cleaning metal materials at home and abroad mainly comprise three types. The first category is solvent cleaning agents, such as solvents of gasoline, kerosene, diesel oil and the like, but the cleaning agents are gradually eliminated due to the waste of energy sources, flammability and explosiveness, insecurity and the like. The second category is halogenated alkane cleaning agents, such as 1-1-1 trichloroethane, which have high cleaning cost and are uneconomical, thus limiting the popularization range. The third class is water-based cleaning agent, and the cleaning agents commonly used at present have the defects of corrosion to the metal surface, poor rust resistance, poor bleaching property, poor biodegradability, toxicity, over-standard phosphorus content and the like, and can not well meet the requirements in the production process.
However, the metallic aluminum material needs to be cleaned before being processed, and generally, the cleaned metallic aluminum material needs to be processed and prepared into elements such as general machine parts and precision components. Because aluminium itself is more active, current cleaner, for the cleaning effect is obvious, adopts the very high cleaning solution of acidity or basicity more, and the in-process of wasing like this is great to the aluminium product corrosivity, has caused the loss of aluminium product to a certain extent. Moreover, the cleaning effect of the existing cleaning agent is not ideal, and especially for metal parts with heavy oil stains, the cleaned aluminum material is easy to have a black surface layer, which brings troubles to subsequent processing and especially causes confusion to the processing of precise components. In addition, the existing cleaning agent has strong corrosion to equipment, and the equipment cost is increased. Meanwhile, these cleaning agents have a long cleaning time, require a cleaning time of 10 to 30 minutes, and have poor rinsing properties. Therefore, the development of a metal cleaner remains one of the problems to be solved in the art.
