KR950017149A - Manufacturing method of artificial marble plate - Google Patents

Abstract

In the present invention, in the preparation of artificial marble using a resin mixture, the synthetic resin film is laid on the upper part of the mold base plate before molding the resin mixture, and then the resin mixture is molded thereon, and then the synthetic resin film is applied thereon, followed by primary curing and It relates to a method of manufacturing artificial marble through a secondary curing step.

Unlike the conventional method, the present invention is characterized in that the artificial marble plate is manufactured by a continuous process using a horizontal mold. According to the production method according to the present invention, it is possible to shorten the time of the process and to significantly improve productivity, such as not requiring a separate surface polishing process.
