Abstract:
A method for preparing artificial acrylic marble by use of an apparatus comprising a rotational body and a liquid resin feeder, the method comprising the steps of:introducing at least two liquid resins into the liquid resin feeder via at least two liquid resin inlets and partially intermixing the at least two liquid resins in the feeder, the liquid resins being different in color and viscosity from each other; discharging through a single liquid resin outlet the partially intermixed resins onto a mobile molding belt used for transferring and curing the discharged partially intermixed resin, wherein the single liquid resin outlet alternately moves from side to side along the width of the mobile molding belt, and wherein the partially intermixed resins on the mobile molding belt have a bottom surface and a top surface; and curing the discharged partially intermixed resins on the mobile molding belt while passing the discharged partially intermixed resins through a rotational body thereby forming a wave/wood pattern in the discharged partially intermixed resins, the rotational body having a rotating shaft with a plurality of spaced wings and rotating clockwise or counterclockwise in the discharged partially intermixed liquid resins on the mobile molding belt to form the wave/wood pattern therein while the discharged partially intermixed liquid resins are cured, the wings being fixed along the shaft of the rotating body and alternately approaching the bottom surface and the top surface of the discharged partially intermixed liquid resins on the mobile molding belt during the rotation of the rotating body.
