(57) [Abstract] [Purpose] Artificial marble with a matte surface manufactured using conventional ground glass as a molding frame has poor releasability, easily breaks the glass, and the molded product also has a feeling of rough rubbing and is heavy. And the delicate feeling is spoiled. The present invention solves this problem and provides a low cost and easy manufacturing method. [Structure] Sheet glass is spaced apart from each other, and the periphery thereof is sealed except for the injection section to form a molding frame, and the undiluted solution of artificial marble is injected into the injection section and cured, and then the molding frame is peeled off and removed. In the method for producing an artificial marble, the plate glass is formed by forming a rough surface on at least the inner surface side by mechanical grinding means in advance, and then performing chemical etching to form a rough uneven surface. |
