Abstract
The present invention is the manufacture method of vertical wood plywood, and it utilizes wood machining residues, the branch bifurcation waste material section of being cut into to make sandwich layer, spreads the middle plate with gluing respectively on the two sides of this sandwich layer, repaves with dash board, backboard in middle plate outside, through hot pressing or cold pressing and form.The wood wool of this kind vertical wood plywood core material is vertical with dash board, and its thickness stability is big.Produce glued board by this law, need not add inside casing wood in advance, can be made into the plate of large format, the time spent can cut arbitrarily, and it is few that its surface can be decorated material this law equipment investment such as various micro veneers again, and abundant raw material is with low cost.
Description
The invention belongs to the manufacture method of glued board.
At present domestic and international existing core-board is to make core with the timber side of being sawn into bar, wide, fillet or plate, two layers of veneer that each multiple wood grain of two sides intersects, and glue laminated forms.In short supply along with timber resources, the material price that can be sawn into above-mentioned core bar up to specification, pellet becomes expensive, thereby the output of this kind core-board reduces gradually.By prior art, wood machining residues and branch bifurcation etc. can not be made the core bar or the plate of core-board, and this class resource is very abundant at present, but never uses.
Purpose of the present invention utilizes waste materials such as wood machining residues and branch bifurcation to make vertical wood plywood exactly, and this technology is abundant raw material not only, and small investment, and is with low cost.
The manufacture method of vertical wood plywood of the present invention is as follows:
1, according to the thickness of desire system vertical wood plywood, and consider that the thickness of coverlay material and compression, wear extent make the length standard that core material should block, press this length standard with raw material, be wood machining residues or branch bifurcation along becoming segment with the vertical direction sawing of wood wool, on supporting plate, it is arranged in intensive chip again, and makes the wood wool of core material vertical with supporting plate.The original profile that the material of this kind chip can leave tree branch shown in Fig. 1-a, also can be to have the cuboid of necessarily deciding thickness (Fig. 1-b) or equilateral hexagonal cylindricality (Fig. 1-c).
2, the middle plate with gluing is tiled on the chip that sequences, the topped again backboard of going up, carbide alloy aluminium sheet on the pad, upset is 180 ° on panel turnover machine, removes supporting plate, spreads the middle plate of one deck gluing more thereon, last topped dash board and the aluminium backing plate gone up, with hot pressing or cold press pressurization, treat to unload after the adhesive curing, promptly become vertical wood plywood of the present invention through cutting edge, sanding.Here used adhesive can be a urea-formaldehyde resin adhesive, also can be phenolic resin glue etc.
Described hot pressing temperature is 105-185 ℃, and pressure is 8-15Kg/Cm
2, described colding pressing, its temperature is 15-35 ℃, pressure still is 8-15Kg/Cm
2Table described here, backboard can adopt veneer, thin glued board, the braided material that approaches particieboard, bamboo mat and rattan seat etc. and various ornamental veneers etc.
Embodiment 1: the paulownia wood branch (moisture content 11%) that 16.5mm is long, setting is arranged in Demountable metallic frame on the supporting plate, and (the interior dead size of frame is in 2030 * 1030 * 14mm), plate (the long 1050mm of thick 1mm) in the paulownia wood of elder generation's lay one deck gluing, the thick area of topped again one deck 1mm is the paulownia plank lagging of 2050 * 1050mm and then the carbide alloy aluminium sheet that covers one page 2100 * 1100 * 2mm, upset is 180 ° on panel turnover machine, after removing supporting plate, put the middle plate of one deck gluing equally earlier, put the high-quality wood grain dash board of 2050 * a 1050 * 7mm again, aluminium sheet one page that loam cake is same is at 125 ℃ and 12Kg/cm
2Under the condition of pressure, hot pressing 10 minutes, release was dismissed burr after 3 hours, promptly became the vertical wood plywood of 2000 * 1000 * 20mm after the sanding, and product is as shown in Figure 2.Through actual measurement, the heavy 326Kg/m of volume
3, water logging (17 ℃) was not come unstuck in 24 hours, 24 hours expansion rate of water absorption average 5.82 ‰ of water logging (17 ℃).Adhesive used herein is to be made into by 1000 aqueous ammonium chloride solutions that restrain pollopas fat and 30 grams 20%.
Implement 2: except that adopting certain thickness cuboid core material, all the other are all identical with embodiment 1, this core material adopts wood machining residues, earlier that its edge and wood wool is vertical direction sawing becomes the high segment of 16.5mm, sawing becomes the rectangular block of 25 * 75mm again, and the length of this rectangle and wide can the variation according to the material situation are decided.Product as shown in Figure 3.
Embodiment 3: except that adopting equilateral hexagon prism core material, all the other are identical with embodiment 1.This kind core material is selected thicker branch bifurcation or wood machining residues for use, earlier that its edge and wood wool is vertical direction sawing becomes the high section of 16.5mm, be die-cut into equilateral hexagonal cylindricality with particular manufacturing craft again, the hexagonal length of side such as its hexagon such as grade is 20mm, and this length of side can be according to the change of every batch of material situation.Product as shown in Figure 4.
Produce glued board by manufacture method of the present invention, need not add in advance inside casing wood, its compression strength, plane tensile strength and generally core-board is similar, the laterally bent strength similarity silently of its MOR and core-board. Because vertical bulking factor of timber is extremely low, so the stability of vertical wood plywood thickness of the present invention is far superior to particieboard and similar wood-based plate. Produce plywood by method of the present invention, thickness is bigger, and cost is lower, and the meaning of joint wood is bigger. Because the equipment investment of this law is few, the tissue that is easy to gather materials on the spot is produced, and its product can be made into the plate of large format, and arbitrarily sawing of time spent is very convenient.
Vertical wood plywood of the present invention can also be made thick plate, decorates in its surface the ornament materials such as micro veneer of various senior textures after fixed thick sanding again, can be widely used as upholstery and the plate fitment of car, ship and building aspect.
Claims (2)
1, a kind of method of making wood-based plate, it is characterized in that making raw material with various wood machining residues or branch bifurcation, through blocking or the mould stamp, its wood wool is erect be arranged in sandwich layer, each spreads the middle plate with gluing respectively on the two sides of this sandwich layer, plate is spread outward with dash board in one deck, and plate is spread outward with backboard in another, carries out hot pressing or cold pressing treatment at last.
2, the method for manufacturing wood-based plate as claimed in claim 1 is characterized in that described glue is urine aldehyde glue or phenol glue etc., and described hot pressing condition temperature is 105-185 ℃ and pressure 8-15Kg/cm
