description The invention relates to a high-flatness aluminized coating. The high-flatness aluminized coating is prepared from the following raw materials in percentage by weight: 10 to 15 percent of inorganic cellulose, 1 to 3 percent of organic coupling agent, 15 to 25 percent of dispersing agent, 17 to 25 percent of aluminum powder, 0.5 to 0.8 percent of ammonium chloride, 0.2 to 0.4 percent of sodium fluoride and 25 to 44 percent of aluminum oxide powder. The invention further relates to a preparation method of the high-flatness aluminizing coating. The high-flatness aluminizing coating provided by the invention can solve the problems that in the existing aluminizing technology, the agglomeration effect between molten aluminum atoms is still not controlled in the aluminizing process, so that the agglomeration of the molten aluminum atoms is not controlled in the aluminizing process; and aluminum atoms are mutually agglomerated due to high-temperature thermal diffusion, so that the flatness of the prepared aluminized
