Manufacturing method of color decorative plate for integral bathroom

A manufacturing method of a color decorative plate for an integral bathroom, comprising:

• 1) preparing a decorative fiber cloth;
• 2) immersing the decorative fiber cloth and preparing a surfacing material, wherein preparing the surfacing material comprises:
• 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 a cinnamene, wherein based on 100 parts by weight of the unsaturated polyester resin, a content of the initiator is 1 to 2 parts by weight, a content of the mold discharging agent is 3 to 5 parts by weight, a content of the accelerator is 1 to 2 parts by weight, a content of the coupling agent is 2 to 4 parts by weight, a content of the crosslinking monomer is 8 to 20 parts by weight, and a content of the cinnamene is 3 to 30 parts by weight;
• uniformly coating the above resin paste on the decorative fiber cloth;
• and
• precuring and drying at 105° C. to 130° C. to achieve 70%-90% of a curing degree of the resin paste to produce the surfacing material;
• and
• 3) conducting compression moulding, wherein conducting compression moulding comprises:
• feeding a sheet molding compound into a mould with a feeding area of 75%-95% of an orthographic projection area of a product;
• and
• laying the surfacing material on the sheet molding compound in the mould for an integral compression moulding,
• wherein 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 a flow of the sheet molding compound and to avoid wrinkling the decorative fiber cloth, and
• wherein the sheet molding compound is used as a structural layer, and the surfacing material is attached to a surface of the structural layer.
