Two-body automobile rear windowsill flat plate capable of purifying air

A back window ledge flat plate of a two-carriage automobile which can purify air belongs to the technical field of gas purification. The back window ledge flat plate is composed of a baseplate 1, an adhesive layer A2, an activated carbon fiber adsorption layer 3, an adhesive layer B4 and a surface layer 5, wherein the activated carbon fiber adsorption layer is attached to the surface of the baseplate. The back window ledge flat plate is characterized in that the activated carbon fiber adsorption layer can be 1, an activated carbon fiber cloth and an activated carbon fiber felt; 2, an activated carbon fiber cloth and an activated carbon fiber felt in composite materials; or 3, an activated carbon fiber flocking. Because the back window ledge flat plate is provided with the activated carbon fiber adsorption layer and activated carbon fiber is a well-known efficient adsorbing material, the back window ledge flat plate can adsorb pollutants in peripheral air without the need of power, thereby purifying the air in
