The technical problem to be solved: de-for being easily generated during the infrared radiation coating use of preparation at present
Fall, the problem such as fracture, and along with the rising of temperature, the infrared radiation property decay of coating is serious, the problem that service life is shorter,
Provide a kind of by by after ceramic powders ball milling, by the way of ball milling intercalation, under potassium acetate effect, destroy mixed-powder
Internal hydrogen bond so that it is during preparing coating, organically combines with organic solvent so that it is in use, not with temperature
Change so that it is not occurring with material matrix to peel off and depart from, the infrared radiation coating effectively solving preparation at present used
Journey is easily generated come off, the problem such as fracture, and along with the rising of temperature, the infrared radiation property decay of coating is serious, uses the longevity
Order shorter problem.
