The method comprises the following specific steps: laminating multiple single wood plates with a laminator; symmetrically paving the plates according to the tension surface by taking the grain direction as the length direction of the plates, and assembling; pressing the plates into laminated plates by using a hot press, wherein the thickness of each laminated plate is 5-14 mm, and the moisture content of each laminated plate is 2-10%; performing single-sided or double-sided lamination on 3-9 laminated plates or sandwiching double-sided laminated single plates among the laminated plates, and vertically superposing; and performing hot pressing or cold pressing to obtain the solid wood door plate. The method provided by the invention well solves the deformation problem of the door plate, controls the bending and buckling deformation of the door plate on the premise of not increasing the production cost, shortens the processing time, improves the production efficiency, prolongs the service life of the solid wood door, and improves the yield and quality of the solid wood door.
Description
Technical field
The present invention relates to a kind of timber processing, specifically a kind of processing and fabricating method of Solid Door sheet material.
Background technology
The structure kind of the Solid Door sheet material that existing building is used (being called for short " door-plate ") is more, has with the centre to make sandwich layer for dredging cloth or densely covered batten, two sides coating panel; The double-deck core-board of employing or density board, particieboard, integrated timber etc. are arranged, form by cementation laminated; Certainly also comprise some other known version.But up to the present, not occurring whole door-plate as yet all is by the bonding Solid Door that forms of the superimposed lamination of multilayer Wooden veneer.This be because, if the mode of production according to existing glued board, be about to the words of the thick door-plate of the once superimposed lamination bonding one-tenth standard 40mm of multilayer Wooden veneer, owing to all contain more water at each veneer itself and in a large amount of binding agents that use, thereby in manufacturing process, need to carry out the hot pressing draining with considerable time, to reduce the moisture content in the sheet forming, this just makes the production cycle of door-plate prolong greatly, and production efficiency is had a strong impact on.If shorten hot pressing time or do not carry out the hot pressing draining, in the door-plate too high moisture content can make Solid Door produce or use in deform, quality problems such as bulge or cracking.And higher moisture content also can make the flatness, flexibility of door-plate etc. become to be difficult to control.
Summary of the invention
Purpose of the present invention just provides a kind of processing and fabricating method of Solid Door sheet material, and is long with the production cycle that solves the overlapping layers pressing plate, moisture content is high and the problem of existing defective such as yielding, easy to crack.
The present invention is achieved in that a kind of processing and fabricating method of Solid Door sheet material, earlier with several Wooden veneers, after gluing machine is crossed glue, as the length direction of sheet material, carry out assembly by degree of tightness in the face of claiming to lay, to be pressed into thickness be the thick and moisture content of 5 ~ 14mm at 2 ~ 10% laminate by hot press with the rift grain direction; After again 3 ~ 9 described laminates being adopted single, double to cross glue or sandwich the two-sided veneer of crossing glue therebetween, superimposed up and down, carry out hot pressing or the back of colding pressing Solid Door sheet material.
The drying shrinkage value of timber after being peeled into veneer, with vertical minimum, radially placed in the middle, tangential maximum, so, with the rift grain direction (vertically) of veneer length direction as sheet material, its advantage is the intensity the when intensity of the whole rift grain bondings of veneer is obviously intersected bonding mode greater than rift grain with vertical line; And, because rift grain belongs to the vertical of veneer, its drying shrinkage or bulking factor minimum, so can guarantee the flexibility minimum of plate length direction, distortion is easy to control.Because the thickness of made laminate is less relatively, so each laminate keeps identical or close controlling and guarantee than being easier to than low-water-content; Again that it is superimposed when being pressed into whole door-plate, the distribution situation of its moisture is stronger than the controllability that all veneers are directly once hot-forming, coherence request to the temperature of the upper and lower pressure bag of hot press reduces relatively, therefore, the possibility of door-plate distortion reduces thereupon greatly, in whole process of production, to the door-plate Deformation Control also with regard to corresponding simplification, and the efficient height, cost is low.
On result of use, owing to be the rift grain bonding between the veneer, the various stress of vertical, horizontal (as temperature stress, moisture expansion and drying shrinkage stress etc.) are much smaller when intersecting moulding than rift grain with vertical line between adjacent veneer, almost nil, therefore, be not prone in the door-plate end in the future and come unglued or finning, can on the big face of door-plate, not occur the phenomenon of cup shake yet, so the result of use with the made Solid Door of this composite board is even more ideal, the life-span is longer.
One of key of processing method of the present invention is to adopt unique pre-hot pressing cooked mode of laminate, all is the length direction of sheet material with the rift grain direction by the multilayer veneer promptly, carries out being hot pressed into laminate behind the assembly in the face of claiming to lay by degree of tightness; Rather than adopt that such rift grain of similar glued board and vertical line intersect mutually, the conventional processing mode of superimposed lamination.The processing mode of this first making layer plywood, because the wood grain lines of each layer veneer is unanimous between the higher and lower levels, therefore when superimposed lamination, between the plate face, will form the mutual embedding of certain texture, the symmetrical laying that is aided with veneer degree of tightness face, can make the combination between the veneer plate face more firm, and avoid phenomenons such as the flexural deformation of made laminate and interlayer cracking.
Two of the key of processing method of the present invention is the cooked modes that adopt stitching by step by step, promptly earlier veneer rift grain assembly gummed is hot pressed into thinner thickness, the ultralow laminate of moisture content; Then, again with the superimposed hot pressing of made laminate or be cold-pressed into the whole sheet material of coincidence gate plate thickness.The processing and fabricating mode of this stitching by step by step because therefore the veneer negligible amounts of each pressing is easier to remove the moisture in the veneer, descends the moisture content in the made laminate fast, thereby satisfies follow-up processing request.Be in the process of Solid Door sheet material with the pressing of several layers plywood, because the quantity of used laminate still less, the moisture that is increased when crossing glue can not considered its outside release, to be laminated finish and reach water balance after, only otherwise can surpass 10 ~ 13% the moisture content that should control gets final product.The door-plate cooked mode of this stitching by step by step has shortened pressing time, and the distortion of door-plate also can be controlled preferably.
The present invention utilizes multilayer veneer, the made sheet material of stitching by step by step to replace the solid wood door-plate, can solve the problem on deformation of door-plate well, make under the prerequisite that does not increase production cost, control the bending and the buckling deformation of door-plate, and shortened process time, improved production efficiency; In use, can avoid Solid Door coming unglued or cracking phenomena of crooked and buckling deformation and Men Bian or plate face to occur, prolong the service life of Solid Door, improve the yield rate and the quality of Solid Door.
The specific embodiment
With 5 ~ 8 layers veneers all with the length direction of rift grain direction as door-plate, after gluing machine is crossed glue, to carry out assembly in the face of claiming the principle of laying, in the temperature range of 120 ~ 180 ℃ of hot presses by degree of tightness, it is pressed into the thick laminate of 5 ~ 14mm, and the moisture content when controlling its time machine is 2 ~ 10%; Just down the laminate of machines is superimposed fast after gluing machine is crossed glue with 3 ~ 9 then, carries out whole hot pressing again or colds pressing, and can be processed into the Solid Door sheet material with standard gate plate thickness.
The glue mode of crossing of laminate has two kinds: a kind of is that the laminate that will just descend machine carries out single or double and crosses glue; Another kind be with veneer is two-sided cross glue after, folder advances between two laminates, to carry out integral body superimposed with laminate.The latter's advantage was to be difficult for too early dried glue behind the glue, helped operation.
