Abstract
The invention provides a preparation method of EO level veneer decoration faced board, key point of which is employing a aldehyde-free high glueyness sequestering agent when daubing sequestering agent on basal plate and a EO level urea-formaldehyde resin adhesive when gluing, and separating the production place from production and stacking place of common faced board to create production environment of free or less aldehyde. The invention is compatible with production facility and process flow of existing environment-friendly type veneer decoration faced plate. Compared with E2 level environment-friendly type veneer decoration faced plate, the EO level veneer decoration faced plate prepared by this invention has excellence of that surface bonding strength is higher above 50 %, release quantity of formaldehyde is low to 0.3 mg/L and come up to the standard of EO level requirement, and the problem for high release quality of formaldehyde is ulteriorly resolved.
Description
Technical field
The present invention relates to a kind of veneer decoration veneer, particularly a kind of E of ultra-low formaldehyde burst size
0The production method of level veneer decoration veneer.
Background technology
The manufacture craft of existing veneer decoration veneer generally be with rounding become veneer drying, assembly, gluing, cold pressing, hot pressing, sanding promptly becomes glued board.This glued board will be as the substrate of veneer decoration veneer.Rare tree log slicing then that wood grain and color and luster is attractive in appearance becomes veneer, with guillotine the burr of veneer is dismissed, and forms the specification veneer of different in width.Then, on substrate, smear masking agent, use glue spreader coating adhesive on substrate after the drying, again by manually veneer fitly being pasted on substrate successively, form the veneer blanket, deliver to cold press and cold pressing, to accelerate the tentatively bonding of veneer and substrate, generally after 1-2 hour, can send and carry out cold sand,, also need afterwards to handle through artificial inspection so that handle the artificial lap seam that produces in the veneer overlay, further repair the piece defective that occurs in veneer and the sanding, just send hot pressing process blanket then, blanket is carried out pressing and stoving, so that the glue heat cure with hot press, reach the bonding strength of standard, at this moment blanket has promptly become the decoration veneer finished product.Owing to when producing, adopted traditional urea-formaldehyde resin adhesive, so have higher burst size of methanal with the decoration veneer of said method production.
Along with The development in society and economy, environmental quality is all more and more paid attention in countries in the world, China is no exception, at formaldehyde having a strong impact on to environment and health, strict regulation has been made to the burst size of methanal among the artifical plate product by country, issued that on January 1st, 2002 " formaldehyde discharges and limits the quantity of in indoor decorating material wood-based plate and the goods thereof " GB18580-2001 forces standard, stops to sell the product that does not meet national standard from July 1st, 2002 on the market.Formaldehyde limit the quantity of branch two standards, i.e. E
1, E
2, E
1Level requires; The E2 level requires.The appearance of this standard and compulsory execution, the product that high formaldehyde is discharged will progressively be withdrawn from the market.Even but E up to standard
1, E
2Formaldehyde among the level artifical plate product discharges and also can affect to health.Therefore developed countries such as Japan, Europe propose and carry out higher standard E
0Level (promptly≤0.5mg/L).And the wood-based plate of this grade is because technology content is higher, manufacture difficulty is bigger, so at present domestic also do not have product to emerge.
Summary of the invention
The purpose of this invention is to provide a kind of ultra-low formaldehyde burst size (E promptly≤0.5mg/L)
0Level veneer decoration veneer and production method thereof.
The present invention is achieved in that and adopts the high adhesivity masking agent of a kind of no aldehyde type when smearing masking agent on substrate, adopt a kind of E when gluing
0Grade urea-formaldehyde resin adhesive, and the production of production place and common thick china, stack the place and isolate is created no aldehyde, aldehyde production environment less.The production equipment of the present invention and existing environment-friendly veneer decorative plate coversheeting plate and process flow system compatibility are according to the E of production method making of the present invention
0Level veneer decoration veneer and E
2Level environment-friendly veneer decoration veneer is compared, and surperficial bonding strength is high more than 50%, and burst size of methanal is low to 0.3mg/L, reaches E
0The grade standard requirement has further solved the high problem of thick china burst size of methanal.E
0Level veneer decoration veneer is a kind of Green environmental-protection building ornament materials, it applies to reducing formaldehyde harm people healthy, build the green health household, create the healthy living environment, improve people's quality of life crucial meaning is all arranged, it is the renewal product of the common veneer decoration veneer of widespread production, use in the market, and market prospects are wide.
Description of drawings
Fig. 1, be production process flow chart of the present invention.
The specific embodiment
In conjunction with Fig. 1 with common thick china production, stack under the situation that the place isolates, coat E after rounding is become veneer drying, assembly
0The grade urea-formaldehyde resin adhesive.This kind adhesive is to be main component with the Lauxite, adds the ultra-low formaldehyde burst size adhesive of melamine, thiocarbamide, the multiple modifier formation of ethylene urea again.Cold pressing then, hot pressing, sanding promptly becomes glued board.This glued board will be as the substrate of veneer decoration veneer.Rare tree log slicing after hydrothermal treatment consists meanwhile that wood grain and color and luster is attractive in appearance becomes veneer, with guillotine the burr of veneer is dismissed, and forms the specification veneer of different in width.Then, on the glued board substrate, smear the high adhesivity masking agent of no aldehyde type, cover the aberration of substrate surface.(refer to three layers of conventional veneer that face veneer pastes) because the used slicing veneer thickness of thick china 0.1-0.2mm, if use the common then wherein contained formaldehyde of aldehyde masking agent that contains to discharge and be easy to, therefore, masking agent will be used no aldehyde type.The component of the no aldehyde type of this kind masking agent mainly is by milky white adhesive 20-35%, titanium dioxide 2-10%, and lithopone 15-25%, calcium carbonate 10-15%, pigment 0.5-2% and an amount of water constitute.Treat to use glue spreader on substrate, to coat E after the masking agent drying
0The grade urea-formaldehyde resin adhesive, its consumption is about 65-75g/m
2Again by manually veneer fitly being pasted on substrate successively, form the veneer blanket, delivering to cold press colds pressing, to accelerate the tentatively bonding of veneer and substrate, generally after 1-2 hour, can send and carry out cold sand, so that the artificial lap seam that produces in the processing veneer overlay, also need afterwards to handle, further repair the piece defective that occurs in veneer and the sanding, just send hot pressing process blanket then through artificial inspection, with hot press blanket is carried out pressing and stoving, so that the glue heat cure, reach the bonding strength of standard, at this moment blanket promptly becomes E
0The decorative faced board finished product of level veneer.
