A thin half-covered TV metal backplane

Abstract

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.

Description

technical field [0001] The invention relates to a film-coated metal plate, in particular to a metal backboard of a thin half-film-coated TV set, which belongs to the field of TV parts. Background technique [0002] At present, the back shell of an ordinary TV is mostly composed of two parts: due to its internal electrical conductivity, the inner material is a metal plate, which needs to be installed with a panel and a circuit board; the outside is a plastic cover to wrap the circuit board and protect it The role of the membrane. Therefore, this type of TV set is generally thicker, and has gradually been unable to meet the needs of consumers for ultra-thin TV sets. [0003] In the prior art, in order to prevent scratches and damages caused by bumps and scratches on the casings of household appliances, the commonly used solution is to paste PE protective films on their outer surfaces, but ordinary PE protective films have many disadvantages, such as : The hardness is not eno...

AI Technical Summary

Problems solved by technology

Therefore, the overall thickness of this type of TV has gradually failed to meet the needs of consumers for ultra-thin TVs.

[0003] In the prior art, in order to prevent scratches and damages caused by bumps and scratches on the casings of household appliances, the commonly used solution is to paste PE protective films on their outer surfaces, but ordinary PE protective films have many disadvantages, such as : The hardness is not enough; the adhesion between the protected product is not firm, and it is easy to fall off and the wings at both ends are lifted during use.
