Title:
WOOD/INORGANIC LAMINATE COMPOSITE MATERIAL
Document Type and Number:
WIPO Patent Application WO/2019/031859
Kind Code:
A1
Abstract:
The present invention relates to a wood/inorganic laminate composite material and a method for manufacturing the same, wherein wood veneers and inorganic boards are laminated alternately so as to improve the physical and mechanical characteristics of the inorganic boards while retaining the advantages of natural wood materials. The wood/inorganic laminate composite material according to the present invention has thin veneers (normally 5mm or less) attached to both surfaces of an inorganic board (plaster board), or has inorganic boards and wood veneers laminated alternately between wood veneers, thereby compensating for the drawbacks of inorganic boards (bending strength, resistance to water, impact strength, heat insulation, and sound-absorbing property), and improving the dimension stability. In addition, according to the present invention, veneers are attached to both surfaces of an inorganic board (plaster board), thereby preventing exposure of the inorganic board to moisture and humidity to the largest extent, and substantially improving the weak screw nail retention power of the plaster board. The present invention employs thin veneers such that, without having to vacuum-pressurizing and injecting a fire-retardant agent, fire retardation and quasi-nonflammability can be provided solely by simple application, thereby simplifying the operation process and reducing the processing time and cost. The laminate complex material according to the present invention can be regarded as a wood product when the ratio of wood veneers is 50% or higher, and thus can be widely applied to existing places finished with plaster boards, ceiling materials, wall materials, and the like.
