Special colorless ink of a kind of washing aluminium high temperature protection and preparation method thereof
Technical field
The invention belongs to printing-ink technical field, be specifically related to special colorless ink of a kind of washing aluminium high temperature protection and preparation method thereof.
Background technology
Along with Flexible Package Market constantly innovation and development, a kind of novel package one is washed aluminium packaging and is arisen at the historic moment, this type of packaging is domestic and even print request is the highest in the world at present, one of packaging that design effect is the most exquisite, improve grade most, be widely used in the outer packaging in the fields such as food, tobacco bale, gift, daily-use chemical industry, electronics, medicine, makeup, apply more in the world, domestic existing minority scale color printing enterprise applies this new production line.
What is called washes aluminium packaging, its technique be by print after color film carry out full version and aluminize, wash off by the aluminium lamination clear water of design requirements by subregion again, and then with other base material compounds, general product structure is VMPET//BOPA//LDPE, PET//BOPA//LDPE or other structures.Compared with common packaging of aluminizing, there is obvious superiority: the common whole bag surface of packaging of aluminizing has aluminium lamination to hide, content cannot be shown very well, wash aluminium packaging and then in the region needing to set off with aluminium lamination printed patterns gloss, luster effect can be reached, also can design transparent visual effect region, therefore, wash aluminium packaging to make through special technique, have outstanding outward appearance and necessarily false proof double effects, market application widely.
The mode of washing aluminium is more, but the most applicable enterprise batch production and the higher mode of production efficiency is that clear water washes aluminium method.The concrete production technique of washing aluminium packaging is as follows: print (printing environment-friendly polyurethane ink, the special colorless ink of inked areas printing washing aluminium high temperature protection, part inked areas or void region printing water-based wash aluminium dumb light ink), aluminize, wash aluminium, compound, slaking, bag.
Due to the singularity of its production technique, fed back by market survey, at present, there is following limitation in the high temperature protection gloss oil that domestic several ink enterprises produce:
(1) do not mate with printing-ink above, add the production cost of color printing enterprise and reduce production efficiency.Require during printing to add a certain amount of solidifying agent in each color ink, and the amount of printing surface larger interpolation solidifying agent is larger, finishes printing the color film of rear requirement and just can aluminize after the curing chamber of 35 ~ 45 DEG C arranges 24 ~ 46h.
(2) be not easy to accurate chromatography, version printing have to be expired, and easily play printing wire-drawing.
(3) ink is corroded in evaporate process.Color film is after vacuum aluminum-coated, and ink layer is destroyed blackening, does not have metalluster.
(4) with ink film forming face affinity and poor with aluminium lamination interface compatibility, after causing compound, sack peeling force is low, generally≤0.4N/15mm (GB/T10004-2008 " composite packing film, bag dry laminating, extrude compound " standard-required >=0.6N/15mm), the easy aliquation of sack, condemnation factor is very high.
(5) have in document and mention the water-based that ink company invented and wash aluminium protection gloss oil; its water-base resin used requires ability complete drying under 150 DEG C of conditions; existing printing equipment and printed substrate all can not meet, and therefore it does not have general applicability.
