Description

Surface treatment method before a kind of lacebark pine plank spray painting
Technical field
The invention belongs to sheet material processing technology field, and in particular to surface treatment method before a kind of lacebark pine plank spray painting.
Background technology
Lacebark pine is aiphyllium, originate in Shanxi Province, China, West Henan, Qinling Mountains in Shaanxi, SOUTH OF GANSU and sky and water Maiji mountain, The ground such as Northern Sichuan Province Jiang Youguanwushan and West of Hubei Province, because its timber is to process, decorative pattern is beautiful, and corrosion resistance is strong, is typically for For building and furniture, stationery are used, lacebark pine plank be finishing in it is excellent in choosing, in order to improve its aesthetic feeling and corrosion resistance Can, it usually needs carry out spray painting treatment to plank, it is poor that plank contact effect after spray painting with paint, in uneven thickness, easy Stick up, come off, influence attractive in appearance, in order to improve this situation, existing various methods are processed plank now, but through existing side Lacebark pine plank after method treatment paint ability and is still had much room for improvement.
The content of the invention
The purpose of the present invention is directed to existing problem, there is provided surface treatment method before a kind of lacebark pine plank spray painting.
The present invention is achieved by the following technical solutions：Surface treatment method before a kind of lacebark pine plank spray painting, including Following steps：
（1）Lacebark pine plank to be processed will be needed to be put into the aqueous solution of urea that mass concentration is 3-7%, soaked 6-8 hours, taken Go out；
（2）By weight, modified calcium lignosulphonate 4-7 parts, sassafras oil 1-3 parts, dimethyl fumarate 2-4 parts, 2- imidazoles are taken Alkanone 2-4 parts, 1-3 parts of l- alanine, semi-refined paraffin wax 0.6-1.5 parts, ammonium chloride 2.6-3.4 parts, dimethylbenzene 26-30 parts mixing After obtain maceration extract, the plank after above-mentioned treatment is transferred in the impregnating autoclave equipped with maceration extract, vacuumize, reach when vacuum- After 0.12~-0.08MPa, 65-70 DEG C is heated to, is kept for 2.5-3 hours, slowly contact internal pressure, after maceration extract is extracted out, taken out Plank；
（3）Plank after above-mentioned dipping is put into after being refrigerated 32-40 hours in 1-3 DEG C of refrigerating chamber, with the sand paper of 120-140 mesh Polishing board surface, is then placed in being soaked 3-4 hours in the aqueous solution that pH value is 5.6-6, is rushed with deionized water after the completion of immersion Wash 3 times；
（4）Dried in vacuum drying chamber, drying condition is 0.5-0.6MPa, temperature is 75-80 DEG C, and drying time is that 6-8 is small When, discharged after natural cooling, can conventionally be painted after discharging.
Used as further improvement of these options, the method for modifying of the modified calcium lignosulphonate is in Lignosite The middle hydrogen peroxide added equivalent to weight 6%, processes under conditions of being 75-80 DEG C in temperature and obtains for 3-4 hours.
Used as further improvement of these options, the temperature of the aqueous solution of urea is 45-50 DEG C.
As further improvement of these options, the step（4）In conventional method of lacquering first to prime, then apply Finish paint.
The present invention has advantages below compared to existing technology：Urea immersion treatment is utilized in the present invention, helps to improve wood The permeability of plate, moisture is uniformly distributed in plank in making the plank of impregnation process, suppresses the activity of enzyme in plank, puts only plank Cracking, while preventing plank after japanning from being damaged from inside, the surface polarity of plank changes, and helps to be combined closely with paint, makes The compactness of paint is improved, and uniformity is good, and paint will not fall off and warp in the good stability of board surface.
