Title:
PRODUCTION OF DECORATIVE LAMINATED BOARD HAVING SURFACE WITH METALIC GLOSS
Document Type and Number:
Japanese Patent JPS5597921
Kind Code:
A
Abstract:

PURPOSE: To produce a metalic-tone decorative laminated board of high quality rich in taste by utilizing an accepted plastic injection molding technique employing a mold obtained from the vacuum molding of a thermoplastic resin sheet.

CONSTITUTION: A thermoplastic resin sheet such as polyethylene is used to form a casting type mold having a tongued and grooved surface by a vacuum molding. A separately prepared solution of a polymerizing oligomer (consecutively polymerizing oligomer such as epoxy system), a polymerizing hardening agent, an accelerator and the like are added to by one kind of metal (e.g. powdered copper and brass) as an essential component and optionally by other powdered metal smaller in the specific gravity than the essential powdered metal, coloring agent, filler and the like to make a mixture. The mixture is injected into the mold, polymerized, hardened and then, released from the mold. The tongued and grooved surface thereof is polished. For example, the mixture uses the blending of unsaturated polyester resin 100pts., methyle ethyl ketone peroxide 1pt., cobalt naphthenate 1pt., powdered electrolyte copper 50pts. and black iron oxide 50pts.
