An adhesive, comprising (A) a polymeric MDI, (B) modified polyvinyl acetate emulsion, (C) aqueous polyvinyl alcohol solution, and (D) a filler. Preferably, a mass ratio of A:B:C:D is 30:(60&#x2013;160):(50&#x2013;160):(10&#x2013;140) provided that the aqueous polyvinyl alcohol solution (C) is in a concentration of 10% by mass.

Adhesives

In production of a decorative board with overlaid wood pieces used for surface covering of various furniture, building materials and car interior decoration, wood pieces supplied from an overhead hopper by gravity are dispersed on a flat feeder by application of vibration and are transferred in a dispersed state onto base boards successively supplied by a transfer conveyor in a horizontal direction. Almost no need for manual operation raises production efficiency and dispersion by mechanical vibration assures high degree of uniformity of patterns on the products. Fully automatic processing enables reproduction of patterns with commerically acceptable fidelity.

Automatic method and apparatus for scattering wood pieces in production

In production of a planar wooden decorative article used for surface covering of furnitures and home interior decorations, a resin prepregnated sheet is prepared by impregnating a material sheet with hardenable resin solution and plurality of resin prepregnated sheets are combined with small wooden pieces to form a laminated composite which is then hardened by heating under pressure. The product has a rich woody impression due to inclusion of the small wooden pieces predominant in the surface region and high toughness coming from the laminated construction.
