Background technology
Aluminium alloy has been widely used in daily life, such as aluminium alloy plate picture, full aluminium family product and aluminium alloy
Decorative plate etc., forms the weight that in bright gay color, air is beautiful pattern is increasingly subject to each research and development institution in aluminum alloy surface for this
Depending on.Chinese Patent Application No. 201210157750.0 discloses a kind of aluminium sheet caloric transfer printing technology, by aluminium sheet oil removing, applies transfer Jie
The processes such as matter, baking, thermal transfer make, but product can not highlight the metallic luster and texture of aluminium alloy itself, and pattern office
It is limited to wood grain, stone pattern effect.
The content of the invention
In view of this, it is an object of the invention to provide a kind of aluminium sheet caloric transfer printing technology, the processing step is succinct, can measure
To change, the product produced using the technique can highlight aluminium alloy its own metal texture, and with anti-corrosion, wear-resisting, painted
Feature.
To reach above-mentioned purpose, the present invention provides following technical solution:A kind of aluminium sheet caloric transfer printing technology, mainly including step
A) surface of aluminum plate pre-treatment, the drying of step b) aluminium plate oxidations, step c) prepare transfer paper, step d) transfers;Further include step e)
Sealing pores and step f) white pickings;
Step e) the sealing pores:First the plate formed on aluminium sheet after transfer is drawn and carries out cold seal hole, then carries out high temperature envelope
Hole;Cold seal hole process parameter control is:Ni2+Mass concentration is 0.8g/L~1.3g/L, and temperature is 25 DEG C~35 DEG C, the time
For 15min;The high temperature hole sealing process parameter control is:Ni2+Mass concentration is 2g/L~2.5g/L, and temperature is 92 DEG C~98
℃;Time is 30min;
Step f) the white pickings:Plate after step e) sealing pores is drawn and carries out pickling, pickling solution is
The mixed solution of 0.5% (volume) glacial acetic acid and 0.7% (volume) sulfuric acid.
Further, the step a), first carries out acid etching to aluminium sheet, then carries out alkaline etching processing, removes surface of aluminum plate
Scrape and injure rolling lines.
Further, the step b), aoxidizes the aluminium sheet after step a) processing, rear drying.
Further, pre-prepared pattern, is printed upon by the step c) using ink-jet printer with heat sublimation type ink
On thermal dye sublimation transfer printing paper.
Further, the step d), transfer paper is attached on the aluminium sheet after oxidation, and carrying out heat sublimation using transfer interpreter turns
Print, wherein, hot pressing temperature is 190 DEG C~200 DEG C, time 10min.
The beneficial effects of the present invention are:The technique uses Al electrochemical film forming mechanism completely, and finished product is without ink, resin etc.
Protective layer, can more highlight the metallic luster of aluminium sheet;Has no concave-convex sense between pattern and matrix, hand touches no embossing feeling, and plate face is more
It is smooth;Using dual hole-sealing technology, can effectively avoid makes the empty flower of pattern during sealing of hole;Pattern color is bright-coloured, multiple color
Be integrally formed, absolutely not ghost image phenomena such as.Integrated artistic is succinct, easily controllable, can be widely applied in aluminium alloy decoration plate.
