Background technology
The mid-90, Korea S printing enterprise is in factory of the middle Office of the State Council, and they bring a kind of ink for screen printing from Korea S, and this printing ink is understood wink-dry and formed a kind of minimum male and fomale(M﹠F) at print surface under ultraviolet irradiation, produces extremely strong stereoscopic sensation.Therefore plant printing ink at wink-dry, save production time and production site (originally printing ink need dry in the air and put drying) greatly, printing surface can play the effect of decoration again.Therefore this kind printing ink is widely used (cigarette-brand, wine mark, makeup outer packaging etc.) in printing industry.But the typography of this kind printing ink is along with the adjustment of national industry structure and environmental protection policy is sound, perfect, and the typography shortcoming of this kind printing ink highlights obviously all the more: (1) print speed slow (2500/h); (2) contain a large amount of volatile organic compoundss (ketone such as benzene series such as benzene, dimethylbenzene, butanone, acetone system, this type of material is big to human body harm, there is clear and definite limit standard in country to this kind solvent on packings such as food, makeup) in the printing ink; (3) ultraviolet ray meeting and air produce ozone, produce unpleasant gas.In order to address the aforementioned drawbacks, abroad, overtesting was once done by more domestic printing ink companies, on offset press or intaglio printing press, use the UV ink printing, but its shortcoming has also showed, print on offset press, speed has improved, but concave-convex effect does not have silk screen printing process strong, naked eyes are not seen concave-convex effect, produce ozone and can't eliminate yet; Print on intaglio printing press, speed is improved significantly, but scraper can not scrape printing ink totally, not needing to cause that dark seal is arranged on the printing surface, causes product rejection, and producing ozone can't eliminate.
Therefore, prior art has yet to be improved and developed.
Summary of the invention
In view of above-mentioned the deficiencies in the prior art, the object of the present invention is to provide a kind of gravure water-based frosted ink and preparation method thereof, be intended to solve existing problem in the prior art.
Technical scheme of the present invention is as follows:

The preparation method of described gravure water-based frosted ink, wherein, stirring velocity is 1000 commentaries on classics/min in the described whipping process.
Beneficial effect: gravure water-based frosted ink provided by the present invention is a water color ink, and major ingredient is an aqueous substance, can not work the mischief to human body; On intaglio printing press, print, speed be improved significantly (15000/h) and can wink-dry; Printing adaptability is good, scraper can not occur and scrape unclean phenomenon, has ensured quality product; Good operability is pressed the common ink printing operation, and the operative employee need not Special Training; The printing surface concave-convex effect reaches the silk-screen effect, and its effect can be regulated arbitrarily according to customer demand.
Embodiment
The invention provides a kind of gravure water-based frosted ink and preparation method thereof, clearer, clear and definite for making purpose of the present invention, technical scheme and effect, below the present invention is described in more detail.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
Gravure water-based frosted ink provided by the present invention, mainly by sand powder, pearlescence, water-borne acrylic resin, water-based wax emulsion, solvent composition, the weight percent of each component is as follows:
Sand powder (diameter<10um) 2% ~ 10%
Pearlescence (diameter<10um) 0.5%-5%
Water-borne acrylic resin 40%-80%
Water-based wax emulsion 10%-40%
Solvent 5%-30%.
In the above-mentioned prescription, the diameter of sand powder and pearlescence is all less than 10um.The sand powder is a kind of frosted wax; can make product surface that coarse sand sense is arranged; and play the wear-resisting and damage resistant of China ink layer below the protection, and it is 2%-10% that thin frosting powder adds limiting quantity, being less than 2% content does not have frosted finish effect; more than 10% printing heap version wire drawing easily; and ink flow is bad, and the existing frosted finish effect of moderate content also has good printability; the user selects in scope according to frosted finish effect.Pearlescence can make the printing ink face that metal effect is arranged, and it is 0.5%-5% that pearlescence adds limiting quantity, and amount does not have flicker effect very little, too many whole color meeting flavescence, and moderate content can guarantee certain flicker degree and the transparent effect of white.Water-borne acrylic resin plays the effect that connects solid material, and be dissolved in water, it is 40%-80% that water soluble acrylic acid adds limiting quantity, resin viscosity is too low and ink flow is bad very little, poor adhesive force, too high resin content viscosity is too high, does not have frosted finish effect after the dilution, moderate resin content promptly guarantees the sticking power of printing ink, and suitable viscosity is also arranged.Water-based wax emulsion is a kind of aqueous polyethylene wax, increases the slippery of frosted oil, plays attrition resistant effect, it is 10%-40% that water-based wax emulsion is added limiting quantity, content is not wear-resisting very little, and too many cost is high and mobile bad, and moderate content makes printing ink that certain wear resistance and flowability be arranged.Solvent plays the dissolved effect, and solvent is the mixture of organic solvent and pure water, and organic solvent is an alcoholic solvent, can be for one or more the mixture of alcohols, as Virahol, ethanol.The interpolation limiting quantity of solvent is 5%-30%, and viscosity height and solvability are bad very little, and too high viscosity is too low, and moderate content guarantees suitable viscosity.
Below be the preferable embodiment of gravure water-based frosted ink provided by the present invention:
Sand powder 5%
