Efficient heavy oil dirt cleaning agent, preparation method thereof and heavy oil dirt cleaning method

Abstract

The invention relates to an efficient heavy oil dirt cleaning agent, a preparation method thereof and a heavy oil dirt cleaning method. The efficient heavy oil dirt cleaning agent is composed of, by weight percentage, 1-1.5% of phosphate, 1-20% of surfactant, 0.1-5% of complexing agent, 0.1-5% of organic alkali, 0.1-2% of buffering agent, 4-10% of organic solvent and water as balance. The invention also provides the preparation method of the efficient heavy oil dirt cleaning agent. The invention also provides the heavy oil dirt cleaning method. The heavy oil dirt cleaning method applies the efficient heavy oil dirt cleaning agent to cleaning heavy oil dirt in a wiping or soaking manner. The efficient heavy oil cleaning agent is a low-phosphorous environment friendly cleaning agent, which can control the phosphorous content to a low level and meanwhile achieve efficient cleaning performance; meanwhile, the efficient heavy oil cleaning agent has the advantages of being high in biodegradability, free from metal carrion, toxicity and influent on paint surface and the like.

Description

technical field [0001] The invention relates to the technical field of oil stain cleaning agents, in particular to an efficient heavy oil stain cleaning agent for cleaning metal materials, a preparation method thereof and a heavy oil stain cleaning method. Background technique [0002] At present, the cleaning agents used to clean metal materials at home and abroad mainly include three categories: the first category is solvent cleaning agents, such as gasoline, kerosene, diesel and other solvents, but such cleaning agents are wasteful of energy, flammable and explosive, Unsafe and other reasons have been gradually eliminated; the second category is halogenated alkane cleaning agents, such as 1-1-1 trichloroethane, etc., because of high cleaning costs and uneconomical cleaning, this type of cleaning agent has limited its promotion scope; The third category is water-based cleaning agents. The cleaning agents commonly used at present all have shortcomings such as corrosion to m...

AI Technical Summary

Problems solved by technology

Because aluminum itself is relatively active, in order to have a good cleaning effect, most of the existing cleaning agents use acidic or highly alkaline cleaning solutions, which are more corrosive to aluminum during the cleaning process, causing the loss of aluminum to a certain extent

Moreover, the cleaning effect of the existing cleaning agents is not very satisfactory, especially for metal parts with heavy oil stains, the aluminum material after cleaning is prone to black surface layer, which brings troubles to subsequent processing, especially for the processing of precision components cause confusion

In addition, the existing cleaning agent is highly corrosive to the equipment, which increases the cost of the equipment

At the same time, these cleaning agents have a long cleaning time, requiring 10 to 30 minutes of cleaning time, and have poor rinsing properties
