PURPOSE:To obtain easily a resin molded piece having a solid-looking stone- work pattern layer by applying or injecting casting resin to a mold box or a mold box having a clear resin layer and then scattering colored mica. CONSTITUTION:As casting resin, is applied casting resin that cures at ordinary and low temperatures such as unsaturated polyester resin, polyurethane resin, methacrylic resin, etc. When resin is used, curing catalyst, accelerator, hardener, etc. are mixed. Colored mica must be scattered in order to stick the mica to the resin before the casting resin applied or injected into the mold box touches the mica and dries. Scattering should be executed excessively, the mica that did not stick to the resin is sucked, removed and collected. In order to prevent the scattered mica from being peeled from the resin, resin is scattered or injected again on the mica. In this manner, a resin molded piece having a high grade stone- work and solid-looking pattern layer can be prepared easily. |
