1 (a) to 1 (e) are schematic views for explaining a color board for an architectural interior material according to an embodiment of the present invention. The color board 100 for a building interior material according to the present invention is produced by injecting 50 parts by weight of the mixture 200 into the mold 10, laminating the mesh net 300 thereon, And then injecting 50 parts by weight of the curing agent 200 to cure it.

Here, the mixture 200 may be a mixture of 80 to 95 parts by weight of the composition and 5 to 20 parts by weight of the additive. Here, the composition can be prepared by mixing a fiber-reinforced plastic hardener, a solidifying agent, a stone powder sludge and a ceramic powder mixture (for example, a weight ratio of 1: 1: 1: 1).

In this case, the powder is discharged in the form of powder during the cutting process of the raw stones. In order to prevent the cutting saw from overheating, water is sprayed and discharged in a wet state. Through the precipitation process, sludge containing not more than 0.8 mm .

At this time, the fiber-reinforced plastic curing agent may include 90 parts by weight of a polyester resin, 7 parts by weight of a curing agent, 2 parts by weight of a DMA curing accelerator, and 1 part by weight of a polyurethane diluent. In addition, the mixture of stone dust and sludge may include 50 parts by weight of the powder of abrasive powder, 20 parts by weight of the carbon material and 30 parts by weight of the polyol solvent.

In this case, the polyol solvent refers to a substance having two or more OH groups in the molecule. Preferably, the polyol solvent is selected from ethylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, dipropylene glycol and polyethylene glycol May be used. The organic material is not particularly limited as long as it is an organic material having two or more hydroxyl groups (-OH) in the molecule.

Also, the solidifying agent may include 10 to 200 parts by weight of high calcium slag dust having a calcium oxide (CaO) content of 40 to 80% with respect to 100 parts by weight of a paper sludge incineration ash having a calcium oxide (CaO) content of 35 to 70% .
