Abstract
The invention discloses a preparation method of a melamine veneer-pasted wooden board, which comprises a wooden board base material, wherein melamine veneer pastes are symmetrically bonded on the upper surface and the lower surface of the wooden board base material, and the melamine veneer pastes are solid wooden veneers which are impregnated by melamine and have different colors or textures; the preparation method comprises the following steps: the solid wood veneer is dipped into colorless and transparent melamine resin, melamine sizing materials are uniformly permeated into the solid wood veneer through dipping, then the solid wood veneer is dried, moisture and solvent volatilization are removed, and then heating and pressurizing are carried out or a cold-hot-cold hot pressing process is adopted for pressurizing and laminating. According to the invention, the natural veneer is directly used for replacing the printed wood grain paper, so that the surface of the plate has solid wood surface stripes, the pollution of formaldehyde in the environment is reduced, and the veneer paste is not easy to fall off, high in wear-resisting strength and lower in cost.
Description
Technical field
The present invention relates to a kind of preparation method of wooden boards, specifically, relating to is the preparation method that a kind of melamine wood skin pastes wooden boards.
Background technology
Lumber core (being commonly called as core-board, woodwork plate) is the glued board with solid wood plate core, and it cuts slivering with log, is spliced into core, and outer veneer material processes, and its vertical (moving towards to distinguish with coreboard) intensity difference is pressed in bending resistance, but laterally bending resistance pressure degree is higher.Plane materiel can be divided into three-ply board, five-ply board etc. by the number of plies; Can be divided into Liu An by seeds; Beech, teak etc., the measured core-board panel surface of matter is smooth smooth, is difficult for buckling deformation; And can sheet material is divided into one side light and please both parties two types according to the sanding surface situation, the sheet material of pleasing both parties can be used as the ornament materials of critical positions such as furniture panel, door and window cover frame.
Multi-layer sheet is three-ply board and three-ply board again, and the different calls of the number of plies are different.What use in the house ornamentation now mainly is the facing three-ply board, promptly in factory, extremely thin solid wood facing is attached on the three-ply board.The facing three-ply board is easy to use, and price is also cheap.
In the prior art, wooden boards has the wooden skin of employing subsides to produce, but complex manufacturing also need be carried out follow-up paint step, is unfavorable for environmental protection, and wearability is also bad.The facing plate has the natural texture and the color and luster of various timber, is widely used in the facing decoration of family and public space.Traditional melamine-impregnated bond paper facing particieboard; The paper that will have different colours or texture is exactly put into the melamine resin adehsive stick and is soaked; Dry solidification mats formation it at surface of chipboard then, the decorative panel that forms through hot pressing; Though this plate low price, humidity, life-span are not low.Some producer was attached to melamine impregnated paper on multi-layer sheet or the lumber core (core-board) in recent years, but relatively the time, the woodgrained paper that prints can be easier to distinguish, and is attractive in appearance inadequately.
Find one Chinese patent application number through retrieval: 200910098824.6, the applying date: 2009-05-15; Denomination of invention: paint-free abrasion resistant veneer and preparation technology thereof; This patent readme is: " paint-free abrasion resistant veneer includes substrate layer, and the one side of substrate layer is fitted with the first surface layer; the first surface layer is the first glued membrane uncoated paper, and first alumina layer that the first glued membrane uncoated paper is coated with dry solidification constitutes first bond paper.Paint-free abrasion resistant veneer preparation technology; Comprise table and layer making step: select the wood grain look of serial pattern, serial ecological natural and the facing paper of plain color for use; Select for use melamine resin adehsive or cyanurotriamide modified urea resin as adhesive; Facing paper forms the glued membrane uncoated paper after adhesive soaks, glued membrane uncoated paper outside spray aluminum oxide forms superficial layer and forms bond paper; Base material is selected step: selected glued board or woodwork plate; Join base applying step: the butt joint of bond paper inner face is fitted selected glued board simultaneously; Or, form and join base facing plate respectively with two selected glued board two sides of bond paper inner face butt joint applying; High temperature overlays step; The deburring decoration step." still, still there is above-mentioned problem, attractive in appearance inadequately.
Summary of the invention
The objective of the invention is to solve above-mentioned deficiency of the prior art, the preparation method who provides a kind of melamine wood skin to paste wooden boards can keep the wood surface striped, reduces formaldehyde pollution in the environment, and difficult drop-off, and scuff resistance is high.
For realizing above-mentioned purpose; The invention provides the preparation method that a kind of melamine wood skin pastes wooden boards; Said sheet material comprises the wooden boards base material, and the upper and lower surperficial symmetry of said wooden boards base material is bonded with melamine wood skin and pastes, and said melamine wood skin pastes the solid wood wood skin that has different colours or texture that is meant through melamine-impregnated; It is characterized in that; The preparation method comprises the steps: solid wood wood skin is impregnated in the water white melmac, through dipping the melamine sizing material is penetrated in the solid wood wood skin equably and goes, then solid wood wood skin is carried out drying; Get rid of moisture and solvent evaporates, carry out heating and pressurizing again or adopt cold-hot-cold heat pressing process to carry out pressurizing attaching to the wooden boards base material and get.
Preferably, after the said drying, solid wood wood skin is placed in the constant-temperature constant-humidity environment with the plastic sheeting sealing and preserves, and temperature is 20 degrees centigrade, and humidity is 50-60%.
Preferably, said heating and pressurizing is in hot press, to carry out heating and pressurizing, and heating-up temperature is 135-150 degree centigrade, working pressure 6-8MPa.
Preferably, said cold-hot-cold heat pressing process pressurizes, and hot plate temperature was lower than 50 degrees centigrade when promptly slab got into press; In order to avoid the resin local solidification, the pressurization that heats up then reduces pressure when before release, earlier hot pressing temperature being reduced to 50 degrees centigrade; Open hot plate, working pressure 6-8MPa.
Preferably, said melamine wood skin pastes, and its surperficial melamine is transparent.
Preferably, said wooden boards base material, its inner core is spliced by little batten, and the slit between the little batten is smaller or equal to 5 millimeters.
Preferably, said wooden boards base material has zigzag tenon mouth to be connected mutually between the little batten of its inner core.
Preferably, said wooden boards is lumber core or multi-layer sheet.
The present invention directly replaces the woodgrained paper that prints out with natural wooden skin on the basis of existing technology, gives pure natural and pure and fresh naturally sensation, has avoided the defective of the wooden skin of simple subsides on wooden boards again, and cost is also lower, also possesses following advantage:
1, avoided brush paint, save both labour and money;
2, the plate surface scratch-resistant, corrosion-resistant, wear-resisting, anti-calcination;
3, sheet material gives the consumer so that the sensation of solid wood to be arranged;
4, the sheet material non-deformability is stronger, and anti-crack ability is better than solid wood.
