The invention discloses a thin type half-covered TV (Television)
metal backboard. The thin type half-covered TV
metal backboard comprises a galvanized steel sheet substrate, wherein the galvanized steel sheet substrate is arranged at the rear side of a TV; a
coating layer is laminated on the rear side surface of the galvanized steel sheet substrate; a
polyurethane adhesive layer, a film covering layer and a hardened protective
coating layer are sequentially laminated on the upper part of the rear side surface of the
coating layer; an anti-
corrosion anti-
fouling coating layer is laminated on the lower part of the rear side surface of the coating layer; the coating layer and the anti-
corrosion anti-
fouling coating layer are sequentially laminated on the front side surface of the galvanized steel sheet substrate; the coating layer is a film prepared from
chromic acid chemical pretreatment solution. According to the thin type half-covered TV
metal backboard disclosed by the invention, the structure advantages and the function advantages are integrated, ultrathin appearance attractiveness and good physical and mechanical properties of electric and
thermal conductivity,
corrosion resistance,
fouling resistance,
impact resistance and the like are integrated, the
hardness is high, the protectiveness is strong, manufacturing materials are saved, and the technology complexity is reduced.
