Description
[technical field]
The invention belongs to print technical field of ink, and in particular to a kind of tetra- color ink of LED of intaglio printing and its preparation
Method.
[background technique]
With the development of the social economy, people require higher and higher to energy-saving and environment-friendly, 19 big propose that conservation cultures are built
If past some backwardnesss influence big business and relevant item therefore by great to environmental protection with Green Development road
Challenge, the nearest enterprise for gradually shutting down many pollutions for 2 years of environmental protection supervise and examine, and our intaglio printings are exactly the dirt to stand in the breach
Metachromia industry contains largely wave here because before this, a large amount of solvent-based intaglio ink is applied in production
Hair property solvent, such as toluene, formaldehyde, the toxic and harmful gas such as methanol.
Traditional solvent-based intaglio ink is usually to be made of resin, pigment, solvent, auxiliary agent and filler etc..In solvent
In resin, Chang Hanyou volatile organic compounds (VOC), such as toluene, trimethylbenzene, formaldehyde, methanol etc., they largely have
Partial solvent will be also added in poison, and the solvent content in solvent-based intaglio ink is generally more than the 65% of total ink, when use
It is adjusted viscosity；The organic solvent overwhelming majority is not involved in reaction and is discharged into air when printing construction, pollutes, to ring
Border pollution is huge.In addition to solvent volatilization, printing layer of ink in work progress also needs infrared heating that could dry, and consumes big energy；
Simultaneously since the volatilization of solvent will also result in collapsing for printing net-point in construction printing process, so making high-precision pattern
There are certain difficulties.
UV UV-curing technology is to form the prepolymer rapid polymerization with reactive group by the irradiation of ultraviolet light
A kind of smooth processing technology of film, the essence to react are the cross-linking reactions that prepolymer resin and monomer occur.With economy
The development of society, requirement of the people to environmental protection and energy saving is higher and higher, and radiation curing replaces traditional heat cure that will become as one kind
Gesture.
Four color ink print speed printing speed 180-200m/min of conventional solvent intaglio plate, the infrared drying tunnel energy of use are not less than
70KW, UV ink generally require 1 second, and UV solidification energy probably needs 24KW；Although UV curing technology intaglio printing industry
Through starting to apply, but due in UV mercury lamp emission energy, about 45% is UV light, other about 55% are long-wave band light,
These long-wave band light carry a large amount of heat, will lead to irradiated object surface and are heated and deform, and generate certain xanthochromia, especially
Intaglio printing ground largely using some the film classes being easily deformed, such as PVC film, OPP film etc., is easy to make after being subjected to UV light
At film breakage, this in the intaglio plate industry of continuous printing be it is nonlicet absolutely, so traditional UV base gravure ink is also difficult always to promote
It opens, also there is technical staff making great efforts the completely new single-range LED technology of low energy consumption being applied to intaglio printing row in industry at present
In industry, but since base gravure ink viscosity is extremely low, print speed printing speed is exceedingly fast, and printing material diversification causes substrate poor adhesive force, surface
Flexibility or hardness are inadequate, need to add especially for reduction ink viscosity and in the case where not adding solvent a large amount of
Monomer, the low then layer of ink crosslink density of resin content are difficult to improve, so the dry speed of LED intaglio plate layer of ink on substrate surface
The requirements such as degree, adhesive force, flexibility, chemical resistance are difficult to reach requirement.
