The invention relates to the technical field of coatings, and provides a
coating composition and a preparation method and application thereof.The
coating composition comprises a
ceramic precursor and resin, and the
ceramic precursor is composed of a
polysilane compound and a
metal precursor; the
polysilane compound is selected from one or more of polycarbosilane, polyborosilazane and polysilicon-
boron-carbon-
nitrogen, and the
metal precursor is selected from one or more of a
zirconium precursor, an aluminum precursor and a
titanium precursor. According to the present invention, the copolymerization product obtained through the reaction of the
ceramic precursor and the resin is adopted as the main body resin of the
coating material, and the ceramic precursor comprises the specific
polysilane compound and the
metal precursor, such that the low adhesion performance of the material surface is achieved so as to effectively prevent the scale generation, improve the
corrosion resistance and reduce the
energy consumption.
