The invention relates to a preparation method of a high-hydrophobicity leather coating agent. The acrylate leather coating agent has excellent film-forming property, light stability, weather resistance and binding property, but has some defects, such as poor water resistance, poor solvent resistance, lack of functionality and the like, due to the linear structure of the acrylate resin.
