Description
Technical field
The present invention relates to a kind of wood-based plate and manufacturing methods, in particular to one kind can surface decorated solid wood directional structure board and manufacture
Method.
Background technique
Traditional wood oriented structure chipboard (abbreviation OSB) is by one kind with small dimension wood, thinnings, wooden core, slab, branch
The timber such as fork material are raw material, flaking are processed into along grain direction by dedicated planing equipment, through drying, sizing and Special spreading
Equipment is by after the criss-cross orienting spreading of watch core layer flaking, then a kind of wood-based plate through hot press molding.
Patent application CN102198684A discloses a kind of oriented wood chipboard and preparation process, during plywood production
Remaining rotary cut venner leftover bits and pieces is raw material, instead of path dimension stock, oriented wood chipboard is manufactured, to save a large amount of wood
Material, reduced production cost.
Above-mentioned oriented wood chipboard there is rough surface, uneven, appearance is not exquisite, cannot directly be adornd with facing paper etc.
Face.
Patent application CN101332614A discloses burnishing surface wood oriented structure chipboard and its Manufacturing approach and use.
Burnishing surface wood oriented structure chipboard, by surface layer, sandwich layer, bottom is viscous and forms, and surface layer and bottom are wooden fines layers.It is smooth
Face wood oriented structure chipboard core manufacturing process be OSB mat formation production line leading portion and most back segment respectively increases by a section and mats formation
Machine, surface layer and bottom before OSB is unformed increase by one layer of fines, and then through hot pressing and plain plate processing, surfacing light is made
Sliding particieboard.
Patent application CN104626292B discloses one kind can facing oriented wood chipboard and its preparation process.Its sandwich layer uses
Rotary cut venner waste material is raw material, and surface layer in the building board production process such as integrated timber, core-board, particieboard, medium density fiberboard using producing
The waste materials such as raw sawdust, wood shavings, useless fiber, sanding powder are raw material, improve the utilization rate of timber, save timber resources, raw material
It is at low cost.
Existing burnishing surface or can facing oriented wood chipboard there are the shortcomings that: upper and lower surfaces fines laminate base, it is big with core plate
Piece wood shavings laminate base, mat formation it is integral mat formation into can facing oriented wood chipboard slab, primary hot-forming, this manufacturer's legal system
Made of making can plaque oriented wood chipboard because sandwich layer stress is larger be easy to become arc, twisted shape etc., and due to flake
In practical manufacturing process, form is inconsistent, and actually pavement process wood shavings arrangement is mixed and disorderly, causes various defects, such as large hole
Hole, bark, the serious wood chip of mildew, special thickness batten, cannot repair, actually affect can facing oriented wood chipboard quality.
Summary of the invention
The purpose of the present invention is: it is relatively rough to solve oriented shaving plate surface, uneven, cannot directly facing ask
Topic, but solve it is existing can facing oriented wood chipboard be easily deformed, sandwich layer defect cannot repair, and influence can facing oriented wood chipboard
The problem of quality, and providing one kind can surface decorated solid wood directional structure board and manufacturing method.
The technical scheme is that
One kind can surface decorated solid wood directional structure board, including sandwich layer and upper and lower surface layer, it is characterised in that surface layer is wooden fines
Or wood fibre, sandwich layer be solid wood directional structure board, sandwich layer solid wood directional structure board with surface wood fines or wood fibre
To have passed through hot-forming solid wood directional structure board before assembly, the wooden fines or wood fibre on upper and lower surface layer are in group of mating formation
For the wooden fines without hot pressing or cold moudling containing adhesive or containing the wood fibre of adhesive when base, upper and lower surface layer with
Sandwich layer becomes by hot pressing or cold pressing can surface decorated solid wood directional structure board.

Oriented wood chipboard with the oriented wood chipboard that rotary cut venner waste material is raw material or has part wood shavings machine direction and vertical, horizontal to press from both sides
Oriented wood chipboard or wafer board of the angle less than 80 °；Core concentration is 0.25g/cm3~0.95g/cm3；
B) it screens: by deformation sorting out greatly, it is small or undeformed as sandwich layer wood oriented structure to leave deformation
Plate is used；
C) the wood oriented structure plate as sandwich layer is screened, the bark big to defect such as hole, serious mildew can
To be repaired；
D) be used as the wood oriented structure plate of sandwich layer, can be select it is coarse rough；It is also possible to select warp
Cross sanding become it is relatively smooth it is a kind of can surface decorated solid wood directional structure board manufacturing method；
4. can the adhesive that uses of surface decorated solid wood directional structure board be environment-friendly urea-formaldehyde resin or phenolic resin or melamine
The modified resin or isocyanates adhesive or MDI of one of amine-formaldehyde resins or these three resins or formaldehydeless natural plant gum
Stick or formaldehydeless chemical adhesive；Can surface decorated solid wood directional structure board, adhesive used in upper and lower surface layer and sandwich layer can be
With type adhesive, it is also possible to variety classes adhesive；
(2) middle section is to mat formation
A) mating formation on production line containing the wooden fines of adhesive or wood fibre containing adhesive by leading portion is ready；
B) leading portion is ready by hot-forming good wood oriented structure plate, mated formation according to product requirement and is placed on
In layer；
C) by leading portion it is ready containing the wooden fines of adhesive or wood fibre containing adhesive to have paved sandwich layer wooden
Above directional structure board and periphery is mated formation upper epidermis；
D) mated formation the slab of upper and lower surface layer and sandwich layer, it can be with precompressed, saw side；
(3) back segment is into plate, compacting post-processing stages:
A) it can be carried out transporting slab according to the requirement of press device and slab is sent into press；
B) slab is suppressed after entering press device, can be hot-forming with hot press, can also be with cold moudling；Compacting
