Embodiment 1

[0061] The decorative board described in this embodiment adopts eucalyptus small-diameter log as the raw material of the finger-jointed board base material, and directly selects the log for slotting and drying, and refers to image 3 Saw and cut the material in the same way, by finger-joining the end and side splicing of the obtained cuboid wood chips 100 of equal thickness, the substrate finger-jointed board is prepared, and then press a layer on the substrate with the same grain direction as the substrate. The vertical veneer is finally pasted with a veneer paper 300 on the outermost layer to make a decorative board.

[0062] The specific preparation steps of the decorative board are:

[0063] 1) Material selection: Select fast-growing small-diameter eucalyptus round wood for the preparation of decorative board substrates according to requirements.

[0064] 2) Cutting and rounding: the diameter of the log is 6.5 cm to 8.5 cm, the cut length is 600 mm to 800 mm, and the diam...

[0076] The specific preparation steps of the decorative board are:

[0077] 1) Material selection: Select fast-growing small diameter eucalyptus round wood for the preparation of decorative board substrates according to requirements

[0078] 2) Cutting and rounding: the diameter of the log is 8.5 cm to 10.5 cm, the length of the cutoff is 800 mm to 1000 mm, and the diameter of the rounded wood is 8 cm to 10 cm.

[0079] 3) Stress release grooves 110 are formed: draw stress release grooves 110 at both ends of the base material small-diameter round material with a length of 8% of the length of the round material, the longest of which is no more than 20 cm, and the stress release grooves 110 are perpendicular to the core of the pith , with a depth equal to the radius of the log and a width of 3 mm.

[0080] 4) Drying: Choose a place with good ventilation and no sunlight exposure to dry the logs naturally to a moisture content of 35% to 55%; then stack the logs into a drying kiln...

[0090] The specific preparation steps of the decorative board are:

[0091] 1) Material selection: Select fast-growing small-diameter eucalyptus round wood for the preparation of decorative board substrates according to requirements.

[0092] 2) Cutting and rounding: the diameter of the log is 10.5 cm to 12.5 cm, the cut length is 1000 mm to 1200 mm, and the diameter of the rounded wood is 10 cm to 12 cm.

[0093] 3) Stress release grooves 110 are formed: draw stress release grooves 110 at both ends of the base material small-diameter round material with a length of 10% of the length of the round material, the longest of which is not more than 20 cm, and the stress release grooves 110 are perpendicular to the marrow , with a depth equal to the radius of the log and a width of 4 mm.

[0094] 4) Drying: Choose a place with good ventilation and no sunlight exposure to dry the logs naturally to a moisture content of 35% to 55%; then stack the logs into a drying kiln at a temperat...

Abstract

The invention discloses a decorative sheet structure and a manufacturing method. The decorative sheet structure is formed by a finger joint sheet, veneers and facing paper in a composite mode; the finger joint sheet is formed by splicing a plurality of wood sheets with finger type teeth and stress relief grooves, wherein the finger type teeth and the stress relief grooves are located at the ends of the wood sheets; the finger joint sheet is connected through the finger type teeth for being longitudinally spliced and is fixed through glue for being transversely spliced. The manufacturing method mainly comprises the steps of cutting, rounding, stress groove forming and manufacturing, drying, board cutting, comb tooth treating, length jointing and width splicing, repairing, sanding, veneer gluing, paper gluing and sheet cutting. The decorative sheet structure has the advantages of being high in strength and good in stability. The manufacturing method of the decorative sheet structure has the advantages that the outturn percentage is high, the production technology is simple, the production efficiency is high, the labor intensity is low and the production cost is low, and the technical problems that the utilization rate of wood is low, the strength of decorative sheets is low and the stability is poor in the existingmanufacturing technology of the decorative sheets are well solved.

Description

technical field [0001] The invention relates to the field of log processing, in particular to a structure of a decorative board and a manufacturing method thereof. Background technique [0002] Due to the deformation of the base material in a humid or dry environment in traditional decorative panels, a series of problems such as loose veneer bonding, peeling of the adhesive layer, and bending of the panel are caused. One of the main reasons is that standard board squares are used for drying in the raw material preparation stage for the production of decorative board base materials. This method has a low yield and is prone to drying defects such as warping, twisting, and cracking. [0003] Patent document CN2608607Y discloses a "heat-resistant and waterproof solid wood composite floor". The glued interface, so degumming will occur. The patent document CN201179674Y discloses a "wooden composite decorative board". The decorative board includes a bottom board, a core board, a ...
