Abstract
The disclosure concerns a hard multi-ply laminate, at least two of the plies comprising primarily wood fibers compressed with a plastic, and an intermediate ply of a different chemical composition than the wood fiber plies, and top and bottom plies of substantially the same physical performances to avoid warping. An adhesive is applied between each of the plies and all the plies are compressed to form a hard laminate. An edge of the resulting board is shaped to form an artistic configuration, and the edges are coated with a moisture barrier. Thus the resulting hard laminate boards with a sculpted edge can be used directly for table and desk tops, shelving and the like without the addition of an edging strip.
Claims24
A flat sheet multi-ply panel board having parallel layers comprising:
- A) at least two layers of compressed wood fiber plastic board, each layer having fibers selected from the group consisting of wood chips, sawdust and cellulosic wood fibers,
- B) at least one layer intermediate said two wood fiber plastic board layers, said intermediate layer being selected from the group consisting of cloth, glass fibers, and plastics,
- C) a top and bottom layer selected from the group consisting of leather, fabric, veneer and high-pressure laminate of substantially similar physical properties to prevent warping,
- D) an adhesive between each of said layers,
- E) a shaped edge on said panel board, and
- F) a moisture barrier coating on at least the edges of said panel board.
A flat sheet multi-ply panel board comprising successively:
- a) a top layer of a high-pressure laminate,
- b) a pair of different compressed wood fiber plastic board layers, one of fine fibers and the other of longer fibers,
- c) at least one central layer selected from the group consisting of cloth, glass fibers, and plastics
- d) a second pair of different compressed wood fiber layers similar to the above said pair of different compressed wood fiber layers,
- e) a bottom layer of a high-pressure laminate of substantially similar physical properties as said top layer to avoid warping of said board,
- f) an adhesive between each of said layers,
- g) a shaped edge on said panel board, and
- h) a moisture-proof barrier coating on at least the edges of said panel board.
