PRODUCTION OF ARTIFICIAL MARBLE LAMINATED SHEET

PROBLEM TO BE SOLVED: To prevent the generation of a problem such as warpage and a crack caused by an environmental change of temp. or humidity and to impart excellent impact resistance by laminating artificial marble to a base material by using a web-shaped hot-melt adhesive. SOLUTION: The partial or entire surface of artificial marble 1 is heated by a hot air drying oven, a rod heater or a far infrared oven. Heating temp. is different by the laminating state of a base material 3 and the artificial marble 1 and, when the artificial marble 1 is laminated only to the surface of the base material 3, the heating temp. is set to the m.p. of a hot-melt adhesive 2 or higher and, when the artificial marble 1 is laminated to not only the surface of the base material 3 but also to the side surface thereof, the heating temp. is set to temp. higher than the m.p. of the hot-melt adhesive 2 and also higher than the thermal deformation temp. of the artificial marble 1. Subsequently, the web-shaped hot melt adhesive 2 is arranged to the surface of the base material 3 and the heated artificial marble 1 is arranged thereon. Thereafter, press molding is performed so as to be fitted to the inner shape of a female mold 6 to obtain an artificial marble laminated sheet.
