Description
Technical field
The present invention relates to a kind of preparation method of wooden core plate, more particularly to a kind of preparation of reinforced wooden core plate in the same direction
Method.
Background technology
Wooden core plate has many kinds, and wooden core plate in the same direction refers to be superimposed what is formed by suppressing using multiple wood based panels, existing
With the presence of wooden core plate cracking in the same direction, insufficient strength, the problems such as formaldehyde have a strong impact on product quality, low quality
What is brought is low value-added and trees wastes, is badly in need of innovation.
The content of the invention
In order to solve problem present in current techniques, it is an object of the invention to provide the reinforced wooden core in the same direction of one kind
Plate.
To reach above-mentioned purpose, the technology used in the present invention means are：A kind of reinforced wooden core plate in the same direction, including under
State step：
First, preliminary working：Plate core wood chip is chosen in sorting, and plate core wood chip is persistently dried to plate core wood chip in 145~155 DEG C of environment
It is aqueous 6~8%；
2nd, connecting plate core：Plate core wood chip is connected into several whole plates by hot melt wire；
3rd, brush coating：Single or double brush coating water is carried out to the whole plate that step 2 is generated, glue is made up of wood glue and flour mixing；
4th, assembly：Multiple whole plates are superimposed in a step-wise manner；
5th, it is cold-pressed：Forcing press, normal temperature compacting are sent into after superposition assembly；
6th, hot pressing：Raw material feeding hot press hot pressing after cold pressing；
7th, health：Semi-finished product feeding after hot pressing is dried into ventilation to place naturally；
8th, bar is opened：Bar is cut into according to the requirement of client's size, you can packaging.
Further, in the step 5, pressing pressure sets 3Mpa, 25~35min of press time.
Further, in the step 6, the pressure of hot pressing sets 14Mpa, 120 DEG C of design temperature, the walking per 2min
1cm。
Further, in the step 7, the time placed naturally is no less than 10d.
Further, in the step 4, ladder width 1cm.
Further, in the step 3, every square metre of amount using glue of one side is 420~470g.
The beneficial effects of the present invention are：Finished product content of formaldehyde meets USA and Europe standard, and density is up to 530~560Kg/m3, by force
Degree is high, and steady quality, no problems of crack, product quality is superior, and added value is much larger than prior art products.
Embodiment
Embodiment 1
A kind of reinforced wooden core plate in the same direction, comprises the steps：
First, preliminary working：Plate core wood chip is chosen in sorting, and plate core wood chip is persistently dried to plate core wood chip in 145~155 DEG C of environment
It is aqueous 6~8%；
2nd, connecting plate core：Plate core wood chip is connected into several whole plates by hot melt wire；
3rd, brush coating：Single or double brush coating water is carried out to the whole plate that step 2 is generated, glue is made up of wood glue and flour mixing；
4th, assembly：Multiple whole plates are superimposed in a step-wise manner；
5th, it is cold-pressed：Forcing press, normal temperature compacting are sent into after superposition assembly；
6th, hot pressing：Raw material feeding hot press hot pressing after cold pressing；
7th, health：Semi-finished product feeding after hot pressing is dried into ventilation to place naturally；
8th, bar is opened：Bar is cut into according to the requirement of client's size, you can packaging.
Embodiment 2
It is preferred as one kind of embodiment 1, in the step 4, ladder width 1cm.
In the step 5, pressing pressure sets 3Mpa, 25~35min of press time.
In the step 6, the pressure of hot pressing sets 14Mpa, 120 DEG C of design temperature, the walking 1cm per 2min.
By be cold-pressed and two steps of hot pressing and pressure, time and temperature control, ensure finished product density up to 530~
560Kg/m3While, it is ensured that the intensity of finished product, and ensure that finished product will not ftracture.
Embodiment 3
Preferred as one kind of embodiment 1, in the step 3, wood glue is mixed in mass ratio with flour.
In the step 3, every square metre of amount using glue of one side is 420~470g.
The control of above-mentioned parameter, together with the control of the moisture of step one, the co- controlling content of formaldehyde so that in finished product
Content of formaldehyde meets U.S.'s P2 standards, and national standard E0.
Being used in conjunction with of wood glue and flour improves bonding capacity, allows more closely knit between layers, prevents cracking.
Embodiment 4
As the further preferred of embodiment 2, in the step 7, the time placed naturally is no less than 10d.
After hot-pressing, semi-finished product are placed in the environment for spontaneously drying ventilation, placed more than 10 days, the plank allowed after extruding
Between clear-cutting forestland and final molding, cutting bar open, it is ensured that while intensity, the problems such as coming unglued will not be produced, adapting to completely
