Description
Technical field
The present invention relates to Recombinant Wood environmental protection application field, in particular to a kind of environment-friendly type Recombinant Wood wood skin veneered plywood and
Preparation method.
Background technique
Recombinant Wood is using common fast growing wood as raw material, using bionics principle, by carrying out respectively to common fast growing wood
A kind of more superior wooden new decorative material of performance for the materializing strategies preparations such as kind is modified, dyes, recombinates.With natural material phase
Than Recombinant Wood has the characteristics that no stammerer, various colors, texture can design, material is stable, wood comprehensive utilization rate is high.Therefore,
By obtained after Recombinant Wood flitch slicing Recombinant Wood wood skin be used for artificial board (such as glued board, core-board) incrustation it is more next
More liked by manufacturing enterprise and designer.
However, Recombinant Wood generally requires to apply adhesive at normal temperature between multilayered wood veneer during the manufacturing
Extrusion forming, the Recombinant Wood of industrialized production mainly first prepares the biggish flitch of specification, since Recombinant Wood flitch specification is larger,
Without the image of Buddha, individual wood-based plate equally carries out hot pressing in forming process, be generally cold-pressed with room temperature based on, adhesive mainly uses often
The cured Lauxite of temperature, Lauxite is not due to by high temperature hot pressing, and product Form aldehyde release after molding is comparatively more
It is serious.Therefore, a kind of Form aldehyde release method of reduction Recombinant Wood wood skin face artificial board is researched and developed to solve Recombinant Wood wood skin dress
Bring formaldehyde pollution problem is adornd, there is realistic meaning to environment protecting green decorative material is developed.
Summary of the invention
To solve the above-mentioned problems of the prior art, the purpose of the present invention is to provide a kind of environment-friendly type Recombinant Wood wood skins
Veneered plywood and preparation method thereof, is effectively reduced the Form aldehyde release of Recombinant Wood wood skin decorative layer, to improve the whole of glued board
