The present invention discloses a thick paste film forming ceramic corrosion-resistant wear-resistant coating composition. The composition consists of a component A and a component B by mass, wherein A:B=(5 to 8):1. The component A comprises the following components by mass percentage: mixed epoxy resin 30-65%, mixed ceramic powder 25-60%, a mixed auxiliary agent 1-5%, and a silane coupling agent 1-5%; The component B is a mixture of a pyridine derivative and an imidazole derivative, and the mass ratio of the pyridine derivative to the imidazole derivative is 1:1. The composition provided by the present invention is readily available in raw material, relatively inexpensive, simple in preparation process, and easy in operation; and the obtained coating has features such as being excellent in physical and chemical properties and being good in corrosion resistance and wear resistance, and has a market prospect of wide promotion and application. The present invention also discloses a preparation method for the thick paste film forming ceramic corrosion-resistant wear-resistant coating composition.
