[0002] The current cleaning agents for rare earth cleaning are all strongly alkaline chemical compositions, including 20%-35% sodium hydroxide / potassium hydroxide, 5%-10% HEDP, 1%-5% sodium tripolyphosphate, The rest is water, the strong alkaline cleaning agent has a corrosive effect on the cleaned objects, the cleaning life is short, and the cleaned objects need to be rinsed with a large amount of water, wasting water resources
Especially in the high-priced rare earth production and processing industry, such as cleaning rare earth packaging or rare earth production tools, there will be residual components, which will pollute the rare earth body

The invention discloses a cleaning agent for cleaning rare earth and a preparation method of the cleaning agent. According to the mass percentage, 15 percent to 50 percent of animal and plant extractsand 5 percent to 10 percent of ethanol are uniformly mixed; and 30 percent to 75 percent of hydrocarbon solvent and 2 percent to 10 percent of surfactant are added and evenly mixed to prepare the cleaning agent for cleaning the rare earth. The cleaning agent for cleaning the rare earth is neutral and environment-friendly, greatly reduces influence on the health of human bodies in contact with thecleaning agent, has no corrosiveness to cleaned objects and cleaning tools, is easy to rinse, has less residues, and makes the produced rare earth purer in components.
Description
technical field [0001] The invention relates to the field of cleaning agents, in particular to a cleaning agent suitable for cleaning rare earths and a preparation method thereof. Background technique [0002] The current cleaning agents for rare earth cleaning are all strongly alkaline chemical compositions, including 20%-35% sodium hydroxide / potassium hydroxide, 5%-10% HEDP, 1%-5% sodium tripolyphosphate, The remainder is water, and this strongly alkaline cleaning agent has a corrosive effect on the object to be cleaned, and the cleaning life is short, and the object after cleaning must be rinsed with a large amount of water, which wastes water resources. Especially in the high-priced rare earth production and processing industry, such as cleaning rare earth packaging or rare earth production tools, there will be residual components, which will pollute the rare earth body. [0003] Therefore, it is necessary to provide an environmentally friendly, easy-to-rinse cleaning a...
