A glass fiber reinforced plastic exterior wall hanging board, the said exterior wall hanging board comprises a base board, a wood grain felt is arranged on the said base board, and an outer paint layer is arranged on the wood grain felt. The background color of the wood grain felt is provided with black textures. The production method includes printing the wood grain on the polyester felt with the color material A, and then compounding the polyester felt with the printed wood grain with the glass fiber felt to form a wood grain felt; using the pultrusion process to compound the wood grain felt on the surface of the substrate , produced according to the FRP pultrusion process, and then subjected to surface grinding treatment to obtain a composite product of wood grain felt and substrate, and then sprayed with paint and colorant B. In the present invention, black color paste is used to print wood grains on the polyester felt with only a base color, and only black wood grain pigments are printed on the felt, which has a small proportion and does not affect the penetration of the resin. In other places, the resin is not easy to penetrate, forming the effect of real wood grain. |
