Description
Technical field
The present invention relates to technical field of ink, more particularly to it is a kind of be adapted to ultrahigh speed printing environment-friendly polyurethane it is compound
Ink composite and its manufacture method.
Background technology
With the development of Chinese society economic and cultural undertakings, the printing press and packing business growth momentum are swift and violent, especially
It is that the domestic demand to flexible packaging printing ink sharply increases, flexible package ink usage in China's remains 25% year by year according to statistics
Rate of rise, this also means that the dosage of resin for printing ink binder is also growing at top speed.Weight of the resin binder as ink
The part wanted, the properties such as the viscosity of ink, viscosity, drying property, mobility have been largely fixed it.The ink of high-quality
The ink of high-quality could be brought up with resin.The main of China's gravure food packing plastics printing industry uses chlorination poly- third at present
The ink of alkene system, it has good adhesive force to PE, PP ground, but the adhesive force to grounds such as PET, NY is not to manage very much
Think, while the system ink is most makees solvent using benzene class aromatic hydrocarbon and ketone and these solvent penetrating odors are larger,
Air is easily polluted during use, long-term suction can influence brain centres nerve, and the health of human body is caused greatly to endanger.With
Environmental Protection in China consciousness reinforcement and《New the law of food safety》A series of sound and announcement etc. safe and healthy regulations is carried out, and China is soft
Ink product is packed for just to develop rapidly towards environmentally friendly, hygienic direction.Using ester alcohol class environmentally friendly solvent polyurethane ink due to
Its modified product is more, has a wide range of application, and temperature tolerance, water resistance are good, and print gloss is high, small toxicity, and development is extremely rapid, just
Gradually accelerate the paces of substitution chlorinated polypropylene ink.
With the horizontal raising of domestic consumption, the quickening of the rhythm of life of urban and rural residents, food consumption idea and mode are just
Quietly changing, digestion resistant food is with its long shelf-life, you can cold food also can warm-served food, easy to carry enjoy that consumer's is joyous
Meet, be commonly called as " foods packed in carton containers "." foods packed in carton containers " refers to use plastics and plastics or plastics and the compounded packaging bag of aluminium foil, such as
The transparent bags such as PET/CPP, NY/CPP, or OPP/ aluminum plated PETs, OPP/ aluminize the nontransparent bag containing aluminium foil such as CPP, PET/AL/PE.
And these packagings need technique by high temperature boiling or boiling, this just not only requires that a variety of base materials are amenable to that high temperature must be played and examined
Test, the packaging bag after more requirement printing is compound has higher combined strength bination.And existing common polyurethane resin humidity resistance
Difference, easily decomposed under high temperature, steam effect so as to reduce the bonding force with ground, this degradation speed when there is metal interface
It can more accelerate and be not suitable with the application requirement of these novel packages.
Meanwhile as the development of social economy and being growing more intense for market competition, each printing enterprise are competitively given birth to improving
Printing efficiency is produced to improve itself competitiveness, one of important method is exactly to improve print speed printing speed.Highspeed gravure at present
Starting up speed can reach 500-600 ms/min to printing machine in theory, but actually due to the limitation of ink performance, printing
Enterprise at most reaches 250-300 ms/min, and more than 350 ms/min of ultrahigh speed printing belongs to the property of experiment test manufacture substantially
Matter.Mainly there are two the problem of limitation superelevation print speed printing speed at present：One is due to the mesh given volume of gravure printing plate, ultrahigh speed
Printing necessarily causes the inking amount of identical printing plate to decline, and the combined strength bination of package compound ink and inking amount have direct ratio pass
System, improve print speed printing speed and but sacrifice combined strength bination, be that printing enterprise is unacceptable.This just needs ink to have higher answer
Close intensity.Second, the ink printing viscosity that ultrahigh speed printing needs is very low, solvent ratios can be many in compound oil ink, while big portion
Divide the evaporation rate of solvent certain, due to printing machine drying tunnel consistent length, ultrahigh speed printing necessarily causes solvent volatile ratio original
Slow, residual can be more than original, therefore dissolvent residual can be caused exceeded and easily return the problem of viscous with ink after print film winding.
This just needs ink to have more preferable solvent release.

Product take out, and peel off the PET film of covering, and whether observation ink layer returns the transparent PET film adhered in covering.Evaluation result is
1-5 points.1 point of area for ink layer more than 90%, which returns, to be adhered in transparent PET film, and 5 points are that ink layer 100% is not returned and adhered to
In transparent PET film.
4. combined strength bination is tested：The ink respectively prepared by embodiment 4-8 respectively on KPP proof presses with 150 lines on the spot
Version is drawn a design on plastic sheeting (PET, NY and OPP), using high alliance 2000S glue on proof press after the gluing of 100 line solids,
It is compound from the progress of different grounds respectively, pressed after 50 DEG C of curing 36h using XLW (PC) Intelligent electronic tensil testing machine (Jinan)
GB8808-1988, measure T-shaped (90 °) peel strength.
The test result of performance test is carried out see table 1 to embodiment 1-4 and control sample.
The embodiment 1-4 of table 1. and control sample performance comparision test result：
Note：Using the formula in embodiment 3, the polyurethane resin that difference is to use changes control sample 1 to be commonly non-
Property polyurethane resin；Control sample 2 is using the formula in embodiment 3, and difference is fine without addition acetate propionate in formula
Tie up plain resin liquid.
The present invention is described in detail according to embodiment and comparative example above, but the present invention is not limited to above-mentioned reality
Example and comparative example are applied, in the knowledge that those skilled in the art possess, the premise of present inventive concept can also not departed from
Under make a variety of changes.
