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.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a ceramic anti-corrosion and wear-resistant two-component epoxy resin coating, in particular to a coating applied to oil pipelines and ship decks requiring anti-corrosion and wear resistance. Background technique [0002] Coatings are an important metal protection measure. General coatings are composed of resins, fillers, additives, and solvents. Special coatings can be made into powder coatings without solvents. But no matter what type of coating, the most important properties of the coating are resin and filler. This means that changing the resin and filler can change the properties of the coating. [0003] With the change of the use environment, there are more requirements for the performance of the coating, which not only requires the coating to have a general anti-corrosion protection effect on the metal, but also requires some special functions. For example...
