The invention belongs to the technical field of fine chemical engineering, and relates to a temporary protective coating, in particular to a temporary protective coating for the surface of a nuclear fuel rod and a preparation method of the temporary protective coating. Comprising the following raw material components: acrylic acid-2-ethylhexyl acrylate, methyl methacrylate, acrylic acid, alkylphenol polyoxyethylene ether, lauryl sodium sulfate, ammonium persulfate, sodium bicarbonate, ammonia water, deionized water, dimethylethanolamine, quartz sand and the like. The developed coating has excellent scratch resistance, so that the surface of the nuclear fuel rod can be prevented from being in direct contact with a spring piece and a bulge on a spacer grid to the greatest extent in the assembly process, and the zero-damage target of the nuclear fuel rod is achieved. The water-soluble lubricating oil has excellent water solubility, can be directly cleaned with hot water after being assembled ...
