Abstract
A kind of production technology that is applicable to the photosensitive decorative board of furniture or interior decoration is characterized in adopting photocureable coating to spray by pouring paint machine on the decorative panel surface, makes through ultraviolet ray irradiation dry solidification behind the spray again.This decorative panel has advantages such as paint film is plentiful, clean, bright, rub resistance, resistance to chemical attack, high temperature resistance steady quality, and it is simple also to have technology, characteristics such as production efficiency height.
Description
The present invention relates to the preparation method that a kind of wood-based plate secondary operations covers jewelry.
At present, people to the requirement of furniture item and interior decoration from color also but more and more higher from the style.Just occurred multiplely with regard to decorating wood-based plate on the market, wherein the application with printed decoration paper facing plate is comparatively extensive.On the market printed decoration paper facing plate modal a kind of be plastic-faced plywood, this plastic-faced plywood is to adopt unsaturated-resin as surface coating, major advantage is that cost is lower.But, when using unsaturated-resin, needs to carry out oxygen barrier and solidify, and with the height of dacron membrane surface brightness, therefore the quality that will directly influence decorative panel just requires often to change dacron membrane (present this film is still by import) with mylar.And plate of every processing, will modulate once (adding curing agent) coating again, stress quality with regard to this point is not easy control very much.Because the employing machine roll extrusion while is extruded air with artificial auxiliary way again, so the very difficult assurance of film thickness evenly, and the coating that is extruded (containing curing agent) can only be lost, and is so the utilization rate of coating is lower, general only about 70%.The cure cycle of plastic-faced plywood generally needs ability sclerosis in 15 minutes under the condition of 25 ℃ of room temperatures, parching needs 2 hours ability demouldings.Therefore use unsaturated-resin except above-mentioned shortcoming, it is low also to exist brightness, and floor space is big, and needs a large amount of big dacron membranes.
The object of the present invention is to provide a kind of new technology of printed decoration paper facing plate, to solve the deficiency that existing technique for manufacturing decorative boards exists.
The object of the present invention is achieved like this, it includes base material polishing, the sticker printed decoration paper of raw material plate, the hot-pressing drying typing, cooling deburring etc., to cool off decorative panel surface after the deburring again through the leaching paint photocureable coating, enter behind the spray that hothouse carries out the ultraviolet ray irradiation if dry curing and the photosensitive decorative board made.
The present invention has been owing to adopted leaching coating process, thereby overcome spraying, irregular shortcoming is covered with paint, lacquer, colour wash, etc. in roller coating.On coating, adopted photocureable coating, adopted modern advanced reciprocating type UV-irradiation technology on the drying means, thereby make coating both obtain the radiation of ultraviolet light and avoided the influence of high-temperature infrared ray filming, make coating light, cleaning after the curing, do not have defectives such as bubble Zou skin.Shorten the film curing time simultaneously, solidified 80～100g/m originally
2Coating needs 3.5～5.8 minutes, and only needs 1～2 minute now.Therefore, photosensitive decorative board has that paint film is plentiful, bright, rub resistance, resistance to chemical attack, and it is simple that the high temperature resistance steady quality also has technology, characteristics such as production efficiency height.
Below in conjunction with flow chart specific embodiments of the present invention is described further.
Fig. 1 is technological process of production figure of the present invention.
Referring to Fig. 1, good for facing plate and substrate (comprising glued board, fiber and various artificial board) are pasted, substrate surface requires polishing to reach level and smooth (base material that has polished can polish separately) degree, and the moisture content of base material is advisable with 6～8; Then the no mimeograph brush decorations paper (also available other facing paper) of choosing pattern being carried out sticker with base material, during the facing paper facing, is to adopt polyvinyl acetate glue to be applied on the substrate surface the about 80～100g/m of glue-spread
2Carry out the hot-pressing drying typing then; After the decorative panel drying, cool off, deburring; Facing plate after the finishing enters pouring paint machine and carries out leaching paint, enter hothouse after the leaching paint again and carry out ultraviolet ray irradiation drying, this section process will be carried out under ashless condition, room temperature is controlled at 15～25 ℃, the coating temperature is controlled at about 25 ℃, makes its viscosity reach 25～27 seconds (with being coated with 4
#Viscosity agent).Work speed can require to adjust according to film thickness, also can increase the leaching paint number of times as required, and coating content is controlled at 70～200g/m
2In the scope; Dry back sheet material cools off a little, just can check, pack, put in storage preservation.The physical detection performance of photosensitive decorative board sees the following form:
| Sequence number | Project | High grade paint face standard-required value | Measured value |
| 1 | Heatproof | 85 ℃/15min paint film no change | No change |
| 2 | Water-fast | 80h paint film no change | No change |
| 3 | Acidproof | 12h (30%HCl) no change | No change |
| 4 | Alkaline-resisting | 6h(10%Na 2CO 3) no change | No change |
| 5 | Glossiness | 90％ | 109％ |
| 6 | Hold power | 90% paint film does not come off | Paint film does not come off on 90% |
| 7 | Abrasion resistance | Do not show money or valuables one carries unintentionally for 4000 times | Do not show money or valuables one carries unintentionally |
In addition, we have also done heat-resisting cold-resistant cyclic test, and the photosensitive plate test specimen is put into-20 ℃ refrigerator 1 hour, and 45 ℃ insulating box 1 hour, ten times so repeatedly, face coat no change are put in the observation after the taking-up again.Also done cigarette simultaneously and burnt test, the cigarette of sorption is lain in photosensitive plate surface 5 minutes, paint film never degenerates.Therefore, from the result of above-mentioned physics and chemistry test as can be seen, the photosensitive decorative board facing has reached country-level product standard, and it is low to have remedied the original brightness of printing paper facing plate, the defective that wears no resistance.
