Electrolyte pollution resistant coating for lithium battery soft package aluminum plastic film as well as preparation method and application of electrolyte pollution resistant coating

The invention discloses an electrolyte pollution resistant coating for a lithium battery soft package aluminum plastic film and a preparation method and application of the electrolyte pollution resistant coating. Waterborne polyester modified organic silicon resin with excellent solvent resistance and acid corrosion resistance is matched with waterborne alkyd resin capable of rapidly drying a coating to form a main body of a medicament formula; the water-based isocyanate curing agent is matched to improve the curing capacity, the baking temperature of an electrolyte pollution resistant coating formed by coating is reduced, and meanwhile, the water-based auxiliary agent is matched to improve the leveling effect when the agent is coated. The coating disclosed by the invention can be used for preparing an electrolyte pollution resistant coating for replacing a PET (Polyethylene Terephthalate) film, so that the yield of the soft-package aluminum-plastic film for the lithium battery after being filled with electro
