Temporary protective coating applied to ocean engineering equipment transportation and preparation method

The invention provides a temporary protective coating applied to ocean engineering equipment transportation and a preparation method thereof, and according to the preparation method of the protective coating for welding spatter, SK (Ss-04) aliphatic radix asparagi manual polyurea is used as a matrix, and a multifunctional antirust lubricant, zinc phosphate and a PU reactive diluent PEC are added to prepare the protective coating. Compared with traditional manual polyurea, the peelable protective paint has the advantages that the peeling strength of a coating is moderate, and the peeling strength of the coating can be adjusted according to requirements; compared with traditional manual polyurea, the peelable protective paint has moderate tear strength, and the coating can be completely peeled off from the surface of a workpiece in a continuous and non-fracture form, so that the peelable protective paint is suitable for temporary protection of the workpiece; compared with traditional anti-rust oil, the peelable
