Description
Technical Field
The invention belongs to the technical field of wood processing, and particularly relates to a method for manufacturing a recombined decorative material by using a high-frequency hot-pressing method.
Background
The recombined decorative material is made up by using single plates of basswood, poplar and Alnus through the processes of bleaching, dyeing, laminating, die pressing and glue-synthesizing and forming. In the gluing process, part of domestic manufacturers adopt a traditional hot pressing mode, for example, a hot pressing process with the pressure of 8.0MPa, the temperature of 145 ℃ and the time of 1.8min/mm is used for preparing 30cm recombined decorative materials as described in patent No. ZL200810104284.3, but in practical production application, if the hot pressing process is adopted, the thickness of a product is severely limited, because the heat transfer of the traditional contact type hot pressing is from the outside to the inside, the thickness of the recombined decorative material plate blank is at least more than 600mm, and thousands of glue layers are arranged among the plate blanks, the transfer path is very long, the phenomena that the surface layer of the plate blank is excessively cured and the core layer is not completely cured are easily generated, so that the density of the square surface and the core layer is not uniform, and the water content of the veneer on the surface layer is too low, thereby influencing the subsequent cutting quality.
In order to reduce energy consumption and ensure gluing quality, most manufacturers prepare recombined decorative materials by a cold-press gluing mode, for example, patent number ZL201410835789.2 describes a cold-press molding process of a technical batten, namely, the pressure is 9 ~ 11MPa, the period is 5 ~ 7 days, but the cold-press pressure in actual production is generally 15 ~ 18 MPa, even more than 20MPa, wood cells in a slab are easily crushed and damaged under the conditions of normal temperature and high pressure, so that the slab has the phenomena of fiber tearing, interlayer fracture and the like.
High frequency heating is receiving increasing attention in the wood industry because of its advantages of uniform, rapid and selective heating. In patent number ZL201410164118.8, a fast growing wood bundle is taken as a raw material, and recombined wood is produced by high-frequency microwave heating, the hot pressing time is only 12min, the production efficiency is greatly improved, but the patent method has the defects that: because press face temperature is low to influence the rising of slab surface temperature, the heat that produces in the heating process slab simultaneously can move to the top layer, forms vapor after the chance is cold and condenses on slab surface and clamp plate, leads to the adhesive solidification on slab surface incomplete, the surface is wet again soft, influences the bonding strength, if gather too much vapor on the clamp plate can produce strike a fire, the slab punctures and burns scheduling problem, threatens personal safety.
Disclosure of Invention
The invention provides a method for manufacturing a recombined decorative material by a high-frequency hot-pressing method, aiming at the problems in the existing recombined decorative material gluing process. The preparation method provided by the invention has the advantages of simple process, high production efficiency and good gluing quality of products. In order to achieve the purpose, the invention is realized by the following technical scheme:
a method for manufacturing a recombined decorative material by a high-frequency hot-pressing method comprises the following steps:
(1) peeling raw wood, rotary cutting, and cutting to obtain veneer A with thickness of 0.4 ~ 2.0.0 mm;
(2) after sorting the veneer A obtained in the step (1), bleaching, dyeing and drying to obtain a veneer B with the water content of 6-16%;
(3) patching, combining, double-sided gluing and assembling the single board B obtained in the step (2) according to design requirements of product texture, color and the like to obtain a board blank, wherein an adhesive used for gluing is urea-formaldehyde resin or melamine modified urea-formaldehyde resin, and the glue application amount during gluing is 200-300 g/m2. The glue application amount is more than that of the common hot pressing process, in the high-frequency hot pressing process, water molecules and adhesive molecules in the plate blank are acted by a high-frequency electric field and rotate and vibrate at a high speed along with the high-frequency electric field, so that severe friction and collision are generated, the dielectric loss of materials in the plate blank is increased sharply, and a lot of heat is generated instantly; the glue application amount is increased, so that the water content of the plate blank is increased, and the heating speed is increased.
(4) And (4) fixing the two plate blanks assembled in the step (3) together with respective dies, wrapping the two plate blanks by using a film, and stacking and placing the two plate blanks between an upper pressing plate and a lower pressing plate of the high-frequency hot press.
(5) And (3) starting a high-frequency generator, electrifying to preheat the metal plate for 5 ~ 10min, closing the press, wherein the hot pressing period is 4 ~ 6h, closing the press when the press reaches the time of 1/2 ~ 2/3, and continuously heating the two recombined decorative material plate blanks between the press plates after the positions of the two recombined decorative material plate blanks are vertically exchanged until the time of the whole hot pressing period is completed.
(6) And after hot pressing is finished, taking out the recombined decorative material plate blank after the recombined decorative material plate blank is cooled to room temperature, removing the film, and performing four-side saw cutting after stepwise pressure relief to obtain the recombined decorative material batten.
Preferably, the raw wood in the step (1) is basswood, alusis or poplar.
And (4) paying attention to the consistency of the elastic surface of each layer of single plate according to the principle of 'loose to loose and tight to tight' of the single plate group in the step (3), and eliminating the stress deformation difference inside the plate blank after the adhesive is cured.
The plate blank in the step (4) is fixed with a die through two flat steel plates by a screw, the pressure is directly applied by depending on the screwing degree of the screw and is 8 ~ 15MPa, and the film can be polyethylene, polypropylene, polystyrene or other resin materials.
The working frequency of the high-frequency hot press in the step (5) is 6.78MHz, the grid current is 0.3-0.5A, and the screen current is 1.2-2.5A. in the high-frequency hot press process, the electric field intensity can change along with the thickness change of the plate blank, and in order to ensure load matching, the ratio of the grid current to the screen current is 1:4 ~ 1: 5.
More preferably, when the log is basswood, the grid current is 0.3-0.4A, the screen current is 1.2 ~ 2.0.0A, when the log is poplar or amus, the grid current is 0.4 ~ 0.5.5A, the screen current is 1.6 ~ 2.5.5A, in actual production, the voltage is usually fixed and unchanged, because grease exists in the basswood, the resistance is larger than that of the poplar and the amus, and under the condition of ensuring the same electric field intensity, the current can be properly reduced.
Preferably, an insulating layer with the thickness of 10 ~ 20cm is arranged between the upper pressing plate and the lower pressing plate of the high-frequency hot press in the step (5) and the plate blank, the insulating layer is a phenolic resin laminated plate or an epoxy resin glass fiber laminated plate or a polytetrafluoroethylene plate, if a stainless steel plate fixed with the plate blank is in direct contact with the pole plate, the potential safety hazard of electric leakage exists, and water vapor can be condensed on the stainless steel plate when meeting cold due to the relatively low surface temperature of the plate blank, so that the phenomena of ignition and breakdown are generated, the safety of production personnel is threatened, the insulating layer is used for avoiding safety accidents on one hand, and is used for reducing the heat loss of the plate blank to the minimum on the other hand, and the production.
And (5) when the two plate blanks are exchanged up and down, the plate blanks do not turn over.
The distributed pressure relief in the step (6) is carried out once every 2 ~ 3min, the pressure is reduced by 1 ~ 3MPa every time until the pressure is reduced to 0, the distributed pressure relief is used for eliminating internal stress generated inside the plate blank due to the difference between the shrinkage degree of the single plate and the shrinkage degree of the adhesive after the adhesive is cured, and is used for ensuring that the thickness of the plate blank is within an allowable deviation range, because the steam pressure inside the plate blank is much higher than the external pressure along with the discharge of a large amount of water vapor after the film is removed, the thickness of the plate blank has certain resilience.
The invention has the beneficial effects that:
(1) according to the characteristics of a high-frequency heating process, all parts in the plate blank are heated simultaneously, the curing degree of the adhesive is uniform, the required hot-pressing pressure is smaller than that of a common gluing process, water vapor continuously moves from inside to outside in the hot-pressing process, and after the plate blank is softened after being cooked at high temperature, a natural transition texture pattern can be formed in the die pressing process, so that the die pressing quality is improved.
(2) The high-frequency hot pressing period is short, the heating rate is improved by increasing the glue application amount, the hot pressing time is only 4 ~ 6 hours, 2 recombined decorative wood battens can be molded at one time, a veneer maintenance procedure is not needed to be additionally added, and the production efficiency is high.
(3) At 1/2 ~ 2/3 of the hot pressing period, the upper and lower positions of the two slabs are exchanged, namely the positions of the lowest temperature region and the highest temperature region in the high-frequency electric field are exchanged, and the adhesive on the original surface layer of each slab is completely cured by secondary heating, so that the problem of incomplete curing of the surface layer adhesive caused by relatively low temperature of the surface layer of the slab is avoided.
(4) A layer of film is wrapped outside the plate blank and the die, and water vapor is sealed around the plate blank in the high-frequency hot-pressing process, so that the curing speed of the adhesive is slowed down, and the phenomenon that a core layer of the plate blank is hardened and embrittled due to too fast curing of the adhesive is avoided, so that the quality of a recombined decorative veneer in the subsequent slicing processing is influenced; meanwhile, after the slab is glued and molded, the batten is continuously cooked by using water vapor, on one hand, the moisture content of each part of the batten can be continuously adjusted to be uniform and stable, on the other hand, the batten can be softened, and the slicing quality is improved.
(5) The upper and lower polar plates are respectively provided with a layer of insulating and heat-insulating layer, so that the heat loss in the hot pressing process is reduced to the maximum extent, and meanwhile, the safety accidents of electric leakage, ignition, plate blank breakdown and the like caused by the direct contact of the stainless steel plate of the fixed plate blank and the mould with the polar plates are avoided.
