METHOD OF PRODUCING AUTOCLAVE WALL MATERIALS WITH COMPOSITE PROTECTIVE-DECORATIVE COATINGS Russian patent published in 2016 - IPC C04B41/50 B28B11/06 

FIELD: technological processes.

SUBSTANCE: invention relates to production of autoclave wall materials with composite protective-decorative coatings and can be used in manufacturing construction materials. Method of producing autoclave wall materials with composite protective-decorative coatings includes semi-dry pressing, autoclave treatment, sputtering of non-ferrous metals using a plasmatron. Prior to plasma sputtering, face surface of autoclave wall materials is coated with 20-40 % aqueous solution of liquid glass, and then plasma sputtering of glass granules pre-coated with fine powder of non-ferrous metals, at power of plasmatron operation of 6 kW and rate of passage of plasma burner on face surface of autoclave wall materials of 0.35 m/s.

EFFECT: high strength of adhesion with base, shorter time for producing autoclave wall materials with composite protective-decorative coatings and reduced power consumption.
