The present invention discloses a manufacturing method of a color decorative plate for an integral bathroom. Firstly, a decorative fiber cloth is immersed and a surfacing material is prepared, wherein the steps include: adding various auxiliaries to an unsaturated polyester resin; uniformly mixing to form a resin paste, wherein the auxiliaries contain an initiator, a mold discharging agent, an accelerator, a coupling agent, a crosslinking monomer and cinnamene; uniformly coating the above resin paste on the decorative fiber cloth; precuring and drying at 105° C. to 130° C. to produce the surfacing material; then compression moulding; feeding a sheet molding compound (SMC) into a mould; and laying the surfacing material on the SMC in the mould for integral compression moulding. In the compression moulding process, a mold cavity is at an upper part and a mold core is at a lower part to prevent decorative patterns from deforming because the decorative fiber cloth is stretched due to the flow of the SMC and to avoid wrinkling the decorative fiber cloth. The SMC is used as a structural layer, and the surfacing material is attached to a surface of the structural layer. The patterns on the surface of a finished product have high clarity and brightness. |
