Abstract
The utility model provides a laminated veneer lumber solid core board of bamboo veneer wainscot, including following component structure: 1) taking a bamboo veneer as an upper surface layer and a lower surface layer; 2) the laminated veneer lumber spliced at an angle of 45 degrees is used as a core layer board; the laminated veneer lumber solid plate veneered by the bamboo veneer has reasonable structure, the splicing of the laminated veneer lumber of the core layer simulates the half-chord radius lumber of the lumber, the strain difference on the thickness and the width is small, and the deformation of the product after the product is compounded is small. After the composite material is compounded with the bamboo veneer, the product has better dimensional stability and small structural stress, and the three-dimensional deformation size of the large-size plate can be better cooperated and restricted in the length, width and thickness directions. The product uses the bamboo veneer as a surface decorative material, so that the solid plate is not only ecological and environment-friendly, but also has good bending resistance and compression resistance. The solid plate has excellent structure and better product stability.
Description
The technical field is as follows:
the utility model relates to an wood-based plate technical field, concretely relates to laminated veneer lumber solid core board of bamboo veneer wainscot.
Background art:
with the rapid development of building decoration and furniture industry, the demand of wood is increased rapidly, and the development of artificial board industry is favorable for relieving the contradiction between supply and demand of wood, and is an important way for saving wood resources. The bamboo veneer has natural and beautiful texture and simple and elegant appearance, and is one of the main facing materials of high-grade decorative facing materials. In order to improve the application of the quality of low-grade fast-growing wood such as poplar on high-grade products, the development of the bamboo veneer facing wood composite material is more and more popular in the decoration field.
The laminated veneer lumber is an artificial lumber which takes small-diameter lumber and low-quality log as main raw materials, is cut into veneers in a rotary mode, is assembled into a blank along grains, is glued and is subjected to hot press molding, and the laminated veneer lumber has the advantages of uniform structure, high strength, good dimensional stability and the like compared with solid wood in a production mode, can meet the use requirements of wood structure buildings and furniture, and simultaneously relieves the shortage of log use. However, the existing laminated veneer lumber is longitudinally pressed, the longitudinal grains are parallel, and the strain in a single direction is overlarge, so that the stress and the deformation are accumulated. This application is for solving the big yielding shortcoming of veneer laminated lumber difference of vertical and horizontal strain, and the panel that will piece together is as decorating the core, and is compound with the bamboo veneer again, has developed a neotype bamboo veneer laminated lumber solid core board that satisfies the field needs of decorating.
The invention content is as follows:
this application is for solving the yielding shortcoming of veneer laminated timber, and veneer laminated timber lath concatenation is for decorating the core, and is compound with the bamboo veneer again, has developed a novel veneer laminated timber solid core board of bamboo veneer wainscot that satisfies the decoration demand. In order to achieve the above purpose, the utility model adopts the following technical scheme:
1. the utility model provides a veneer laminated wood solid core board of bamboo veneer wainscot which characterized in that: the laminated veneer lumber solid core plate sequentially comprises an upper surface layer (1), a core layer (2) and a lower surface layer (3) from top to bottom, wherein the upper surface layer (1) and the lower surface layer (3) are bamboo veneers with the thickness of 0.4-3.0 mm; the core layer (2) is an obliquely spliced laminated veneer lumber with the thickness of 11 +/-0.2 mm; phenolic resin adhesives are applied among the upper surface layer (1), the core layer (2) and the lower surface layer (3) to prepare the laminated veneer lumber solid core board with bamboo veneer veneers.
2. Furthermore, the core layer (2) is formed by splicing laminated veneer lumber strips which are arranged at an angle of 45 degrees, and the directions of the veneers of the adjacent strips are opposite.
3. Furthermore, a gap of 0.1-0.3 mm should be reserved in the length direction of the laminated veneer lumber batten in the core layer (2) during lengthening and splicing, and a gap of 0.5mm should be reserved in the width direction during widening and splicing.
4. Furthermore, the upper surface layer (1) and the lower surface layer (3) adopt bamboo veneers, which not only comprise bamboo veneers made of bamboo collecting materials and recombined bamboos, but also comprise bamboo veneers formed by rotary cutting of raw bamboos or bamboo veneers made of unfolded bamboo chips.
5. Furthermore, the upper surface layer (1) and the lower surface layer (3) are bamboo veneers with the thickness of 0.4-3.0 mm; the core layer (2) is an obliquely spliced laminated veneer lumber with the thickness of 11 +/-0.2 mm; phenolic resin adhesives are applied among the upper surface layer (1), the core layer (2) and the lower surface layer (3), and the solid veneer laminated wood board with bamboo veneer veneers is manufactured through assembly and hot press molding.
The utility model has the advantages that: the core layer laminated veneer lumber reduces the growth stress concentration of the fast growing wood, and the manufactured laminated veneer lumber structurally simulates the half-chord radius lumber of the wood, so that the strain difference on the thickness and the width is small, and the deformation of the product after compounding is small. The product has better dimensional stability and small structural stress, and the three-dimensional deformation dimension of the large-size plate can be better cooperated and restricted in the length, width and thickness directions.
Description of the drawings:
fig. 1 is a schematic structural diagram of the present invention.
The specific implementation mode is as follows:
example (b): the laminated veneer lumber solid board with bamboo veneer veneering has a finished product thickness of 12.5mm, is of a 3-layer structure, and sequentially comprises an upper surface layer (1), a core layer (2) and a lower surface layer (3) from top to bottom.
Step 1) upper surface layer (1) and lower surface layer (3): adopting a bamboo veneer with the thickness of 0.4-3.0 mm.
Step 2) core layer (2): the laminated veneer lumber is spliced obliquely with the thickness of 11 +/-0.2 mm. The included angle between the glue line direction of the spliced laminated veneer lumber strips and the horizontal direction of the width is 45 degrees +/-5 degrees.
And 3) coating phenolic resin adhesives on the surfaces of the upper surface layer (1), the core layer (2) and the lower surface layer (3), sequentially assembling to prepare a plate blank, and curing the plate blank for more than 48 hours to prepare the decorative laminated veneer lumber solid plate.
The present invention has been described in detail with reference to the specific embodiments, but the present invention is only by way of example and is not limited to the specific embodiments described above. Any equivalent modifications and substitutions to those skilled in the art are intended to be within the scope of the present invention. Accordingly, variations and modifications in equivalents may be made without departing from the spirit and scope of the invention, which is intended to be covered by the following claims.
