METHOD OF MANUFACTURING A DECORATIVE BUILDING PANEL Russian patent published in 2019 - IPC B05D3/08 B05D7/14 E04F13/12 

FIELD: construction.

SUBSTANCE: invention relates to a method of producing a decorative building panel, comprising processing in desired conditions before printing reliefs by means of jet printing on metal substrate surface of metal facing material used in the field of construction materials. Described is a method of producing decorative building panel with metal facing material, comprising metal substrate, material of core and material of rear side. On the metal substrate there is a relief with depressions and protrusions, having a height difference of 0.5 mm or more, and an ink receiving layer formed from the resin composition is provided. Metal facing material is subjected to flame treatment by acting on metal facing material with flame with output power of 250 to 12,000 kJ/h per 10 mm width of outlet hole for a burner flame such that substrate surface temperature does not exceed 300 °C, followed by jet printing using curable by active ink rays.

EFFECT: technical result is providing a method of producing a decorative construction panel with high structural properties, which provides uniform spreading in moist condition of curable ink by ink during jet printing on metal facing material using said ink.
