Description
Technical field
The present invention relates to a kind of aluminium shape surface process for producing technique, particularly relate to a kind of aluminium section bar stereo wood pattern production technology.
Background technology
Along with expanding economy, the raising of people's living standard, people have higher requirement to the door and window in living environment, floor etc.: not only durable in use, and elegant in appearance.The aluminium section bar with stereo wood pattern has the advantage of aluminium section bar light durable, the decorate properties of the three dimensional designs of wood grain concrete high-quality again.
The wood grain production technology of prior art does zero diopter process to aluminium shape surface, and surface effect is uneven; And adopt the surface effect of the spraying coating process of Thermal-printing Technology larger by the impact of background color spraying.Background color adopts pressed powder to occur pin hole, shallow hole etc., has had a strong impact on the surface effect of stereo wood pattern aluminium section bar.
Summary of the invention
Instant invention overcomes the shortcoming of prior art, provide a kind of aluminium section bar stereo wood pattern production technology, while raising aluminium shape surface mechanical performance, increase the decorative effect of stereo wood pattern.Technical scheme of the present invention is as follows:
A kind of aluminium section bar stereo wood pattern production technology, is characterized in that comprising step:
Step one: aluminium section bar pretreatment.
Step 2: will the pattern electrostatic spraying of powder according to wood texture be solidified at aluminium shape surface.
Step 3: the aluminium section bar through step 2 process is carried out alkaline etching, forms three-dimensional texture at aluminium shape surface; Subsequently aluminium section bar is carried out acid degreasing and remove the solidification powder covering aluminium shape surface.
Step 4: Ultrasonic Cleaning is carried out to the aluminium section bar through step 3 process.Hyperacoustic molecular vibration effect is conducive to the acid residue in aluminium shape surface hole to shake out.
Step 5: inflating stirring process is carried out to the aluminium section bar through step 4 process.In inflating stirring process, add the flowing of cleaning liquid, be conducive to the acid dirt of remnants to take away aluminium shape surface.
Step 6: by polyester/TGIC powder coating electrostatic spraying through step 5 process aluminium shape surface and be cured.Solid powder paint has good ornamental, protectiveness and higher coating efficiency.
Step 7: adopt vacuum wood grain film coating technique wood grain heat to be transferred in the dusty spray of aluminium shape surface.Vacuumize the transfer printing of overlay film Post RDBMS, transfer printing grain pattern is out clear, fidelity is high.
As preferably, in described step 2, spray gun technological parameter is: air pressure 50 ~ 150Kpa, electrostatic potential 60 ~ 70KV.Under the double action of electrostatic force and carrier gas, powder forms uniform bisque at aluminium shape surface equably.
As preferably, the work sound intensity 1.41W/cm of ultrasonic drilling machine described in described step 4
2.Under high ultrasonic intensity, residual acid molecule obtains higher energy, and motion is more violent, more easily leaves aluminium shape surface.
As preferably, in described step 4, Ultrasonic Cleaning process duration is 5min.Continue the long-time ultrasonic wave of 5min, make to ensure that as far as possible many residual acid molecules obtain enough energy and leave aluminium shape surface.
As preferably, the process for preparation of polyester described in described step 6/TGIC coating powder: prepare 90 ~ 95 parts, mylar, isocyanuric acid three-glycidyl ester 5 ~ 10 parts by weight; The raw material prepared are mixed; Melt extrude; Compressing tablet meal is pure; Abrasive dust fine powder is broken; Sieve and obtain diameter to be granular size the be polyester/TGIC powder of 20 ~ 80 μm.Powder diameter is less, and thermal capacity is low, and during solidification, melt stage required time is short, accelerates solid particles agglomerate levelling film forming and obtains desirable film coated surface effect; Powder diameter large melting levelling required time is longer, and film easily produces orange peel, pin hole etc.; But the too small meeting of powder diameter causes powder flowbility, charging property poor, the powder ball gathered in use procedure easily blocks up rifle, tells powder; .Powder diameter size is controlled can obtain desirable film coated surface effect at 20 ~ 80 μm, the mobility that powder is desirable and charging property can be ensured again, reduce stifled rifle and the generation of telling powder phenomenon.
As preferably, in described step 6, spray gun technological parameter is: air pressure 400 ~ 500Kpa, electrostatic potential 60 ~ 80KV.The too high meeting of air pressure causes decorative pattern poor definition; The too high meeting of electrostatic potential makes the powder generation rebound phenomena being attached to aluminium shape surface occur pockmark, and levelling is not good enough.
As preferably, in described step 6, hardening time is 30min, wherein temperature rise period 8min, holding stage 20min, cooling stage 2min; Holding stage melt temperature is 200 DEG C.Temperature rise period keeps 8min, guarantees powder particle melting, levelling.Holding stage 20min, ensures sufficient hardening time, avoids solidifying not enough phenomenon.
As preferably, the described solidification powder in described step one adopts polyurethane powder; Described polyurethane powder granular size is 70 ~ 100 μm.Be conducive to forming obvious decorative pattern and larger decorative pattern.
A kind of aluminium section bar stereo wood pattern production technology disclosed by the invention has following beneficial effect: described step 4 and step 5 carry out ultrasonic wave and inflating stirring cleaning to the aluminium section bar after overcuring respectively, cleaning fully ensures that in step 6, on solid powder paint, powder is even, powder craft parameter and hardening time on strict control pressed powder, improve sprayed surface effect, ensure that the wood grain after hot transfer printing is more fine and smooth true to nature.
