As a limitation of the utility model, the thickness of each layer of single plate is 3.0 mm.
As another limitation of the present invention, the fiber direction of both the upper decorative panel and the lower decorative panel is coincident with the length direction of the core panel.
As a further limitation of the utility model, the thicknesses of the upper decorative panel and the lower decorative panel are both 0.1-0.15 mm.
As a third limitation of the present invention, the flame retardant adhesive is formed by mixing a melamine formaldehyde resin adhesive and a flame retardant.
As a further limitation of the present invention, the core panel is formed by assembling and gluing aldehyde-free thermoplastic resin adhesive films between the plurality of single sheets.
Due to the adoption of the technical scheme, compared with the prior art, the utility model has the following beneficial effects:
(1) the thickness of each layer of single plate in the core plate can reach 2.7-3.2 mm, and compared with the single plate with the thickness of 1.0-2.0 mm in the prior art, the core plate has better deformation resistance. In addition, when the core board is actually manufactured, the number of the layers of the veneers needing to be overlapped and assembled is relatively less, the processing is simpler, and the plywood manufactured by the core board has stronger integral layering and better aesthetic property.
(2) The utility model adopts the single plates with the thickness of 3.0 to manufacture the core plate, reduces the number of layers of the single plate superposed assembly, and simultaneously correspondingly reduces the glue consumption. In addition, the veneer is glued and fixed by the formaldehyde-free thermoplastic adhesive film, and compared with the formaldehyde-free adhesive used in the prior art, the manufactured veneer is green and formaldehyde-free, and is more environment-friendly and healthy.
(3) The utility model adopts the surface flame-retardant technology, utilizes independently developed flame-retardant glue to bond and fix the decorative panel on the core plate, and can ensure that the plywood can meet the requirements of national standard flame-retardant standard only by using the flame-retardant glue on the surface layer, and has excellent flame-retardant performance.
(4) The fiber directions of every two adjacent veneers in the core board are mutually vertical, so that the anisotropic characteristic of the natural wood can be effectively improved, and the plywood has uniform characteristic and stable shape; the fiber directions of the upper decorative veneer and the lower decorative veneer are consistent with the length direction of the core plate, so that the surface layer of the finally formed plywood can have certain flexibility, and the texture of the surface of the plywood is more natural and beautiful.
In conclusion, the utility model has the advantages of stable structure, strong layering, high bonding strength and good flame retardant property, and is suitable for the fields of furniture manufacture, interior decoration, ship manufacture, light industrial products, packaging and the like.
