In the process of molding a lightweight composite plate, a pattern transfer film 1 in which a plastic film or paper is pre-coated with a paint is laid on the surface of the metal form plate 7, or a powder thermosetting resin or a liquid synthetic resin is used. A decorative layer 6 having a surface pattern is formed by spraying or applying a mixture of an inorganic powder, an inorganic pigment and an inorganic filler, and further, a thermosetting resin powder, an inorganic powder and a reinforcing fiber are formed on the decorative layer 6. Surface layer 2
And a core layer 4 composed of a powder thermosetting resin, an inorganic powder and an inorganic lightweight aggregate, and a back surface layer 5 composed of the powder thermosetting resin, an inorganic powder and a reinforcing fiber, which are laminated in order to form a sandwich structure. None, by heating and pressurizing with a heat press machine 9, the raw material powder is solidified, and at the same time the surface decorative layer is firmly adhered, forming a durable, beautiful and lightweight composite plate with various patterns integrally it can. The patterned transfer film 1 coated with the pigments used in the present invention is not particularly limited as long as it has excellent releasability and heat resistance as a base film, but polyester, polyethylene, polypropylene,
Nylon-based plastic films and paper sheets are used. Further, the pattern of the patterned transfer film 1 coated with pigments has various patterns such as wood grain, stone tone, abstraction, and pattern. The powder thermosetting resin used in the present invention is a phenol resin,
Any material such as urea resin, melamine resin, or epoxy resin which is powdery at room temperature and melts and cures when heated and pressed may be used. The inorganic powder used in the present invention includes fly ash, shirasu balloon, calcium carbonate, aluminum hydroxide, powdered glass and the like, which are used alone or as a mixture. It is preferable to use a material having a particle size in the range of 0.05 to 0.5 mm so that the inorganic lightweight aggregate can be densely laminated without being broken by the molding pressure. The inorganic lightweight aggregate used in the present invention is pumice stone, volcanic rubble, perlite, etc., and preferably has a particle size in the range of 1 to 5 mm.
It varies depending on the combination with the inorganic powder in order to reduce the weight of the composite plate. The reinforcing fiber used in the present invention is an inorganic fiber chopped strand such as glass fiber, carbon fiber, rock wool, and metal fiber, and its length is 25 to 25.
35 mm is good in terms of dispersion and strength. The inorganic pigment used in the present invention includes titanium oxide, chromium oxide, red iron oxide, cobalt and the like. In particular, when an unsaturated polyester resin is used, care must be taken because the inorganic pigment may hinder the curing. The inorganic filler used in the present invention is a lump aggregate or limestone, mica, quartz, sand or the like obtained by crushing natural stone such as cold water stone, marble, granite, serpentine, etc., alone or in a mixture. To use as. In terms of cosmetic properties, it is relatively favorable when the particles having a particle size of 0.05 to 1 mm and the particles having a particle size of 1 to 3 mm are mixed at a ratio of 1: 1 to 1: 2.

As is clear from the above description, the present invention, when manufacturing a lightweight composite plate, by integrally molding the step of solidifying the laminate of the powder mixture by heating and pressing and the step of surface cosmetic coating, It eliminates the painting process and enables efficient production of various patterns. The effects of the invention described in claim 1 are as follows. Since it is laminated on the transfer film, the process is simple and the manufacturing cost is low. In addition, since the transfer film pattern becomes a surface decorative pattern, it is possible to fabricate a lightweight composite board having the same pattern such as woodgrain and pattern. The effects of the invention described in claim 2 are as follows. By using a transparent transfer film, a wide variety of surface decorative patterns can be applied by overlapping with the decorative layer pattern of the base surface. The effects of the invention described in claim 3 are as follows. By changing the combination of the inorganic pigment and the inorganic filler in the decorative layer, it is possible to combine the color and the particle size, and various stone patterns can be applied. The effects of the invention described in claim 4 are as follows. By using liquid synthetic resin,
Viscosity is imparted, and spray coating method can be used in addition to spraying method. In addition, the surface decorative pattern becomes transparent and glossy as if it had been UV-painted. The effects of the invention described in claim 5 are as follows. By applying a decorative pattern on both sides of the lightweight composite board, for example, one side has a stone pattern,
It is possible to have two types of patterns with one plate, such as having the other surface have a woodgrain pattern. Further, the lightweight composite board having a double-sided decorative pattern can be used as a member such as a partition board.
