Coating layer sealing material and preparation method and application thereof
The invention discloses a coating layer sealing material including an organic silicon resin hole sealing agent A, a micron-size talcum powder B, a mixture C, an auxiliary agent and an anhydrous ethanol solvent, the mass ratio of the organic silicon resin hole sealing agent A to the micron-size talcum powder B to the mixture C is 100 to (40-60) to (60-120), the auxiliary agent accounts for 5-7% of the total mass, and the mass ratio of the organic silicon resin hole sealing agent A to the anhydrous ethanol solvent is 1 to (1-1.3); the mixture C includes modified nano-size silicon dioxide and micron-size titanium dioxide, wherein the content of the modified nano-size silicon dioxide accounts for 50-100% of the total mass of the mixture C. The invention also discloses a preparation method of the coating layer sealing material, and a use of the coating layer sealing material for sealing treatment of a plasma sprayed ceramic coating layer. The coating layer after being sealed by the material has both excellent corrosion resistance and water biological adsorption resistance.
