Description
Technical field
The present invention relates to aqueous aluminum foil ink and preparation method thereof, especially relate to a kind of aqueous aluminum foil ink take pure-acrylic emulsion as base-material and preparation method thereof.
Background technology
Since reform and opening-up, growing along with China's Printing industry, the quantity of ink of domestic needs is increasing, and the printing ink kind is more and more, and quality scale is more and more higher, and environmental consciousness is more and more stronger.At present, printing industry is constantly to high-grade packages printing and environmental printing future development.But at present in China, in printing process, a large amount of printing ink that use are solvent type ink basically, and the organic volatile of these solvent type inks is not processed, and directly enters in workshop air, not only production environment is affected, also great harm will be arranged to workman's health.This is because these solvent type inks contain the volatile organic content of 50-60%, in addition, also usually add in the production process of reality and raise the required thinner of ink viscosity, when printing was dry, the total content of the volatile constituent that printing ink comes out was even up to 70-80% so.
Water color ink is referred to as ink, it is mainly formed through abrasive machining by water soluble resin, pigment dyestuff, solvent and relevant auxiliary agent, and water color ink is specially adapted to the strict Packaging Printing Products of health conditions requiring such as cigarette, wine, food, beverage, medicine, toy for children.Water color ink is take water (45%-50%) as solvent, and VOC content is extremely low, and environmental pollution is little; Solvent type ink is take organic solvent (toluene, dimethylbenzene, industrial spirit etc.) as solvent.At Flexible-Packaging Industry, be main mode because solvent type ink all adopts the volatility drying, the boiling point of solvent is lower, just more volatile and discharge the toxic gas contaminate environment, also there is residual toxic substance on its surface after being completed for printing, and the solvent that water color ink uses is water and the ethanol got rid of from the VOC list etc., can greatly reduce the discharging of VOC.
The base-material that water color ink is commonly used is aqueous solutions of polymers and polymer emulsion.Available polymers soln has the aqueous solution of the materials such as starch, treated starch, dextrin, cellulose family, polyvinyl alcohol.Because water-soluble polymers has molecular weight lower, viscosity is large, solid content is little, water-resistance property of coating is poor, the defectives such as mechanical property and weather resistance are unsatisfactory, so the higher water color ink binder used of class mostly is polymer emulsion at present, as pure-acrylic emulsion, benzene emulsion, vinyl acetate emulsion, carboxylic styrene butadiene latex, polyaminoester emulsion, EVA emulsion, epoxy resin microemulsion, Synolac microemulsion etc.Wherein pure-acrylic emulsion has the excellent properties such as film adhesive is large, glossiness is high, look shallow, transparency is high, good weatherability.
In above production and Application Areas, problem has very real meaning to the printing ink produced of the present invention to solving in sum.
Summary of the invention
Technical problem underlying solved by the invention is to provide a kind of environment-friendly type aqueous aluminum foil printing ink take pure-acrylic emulsion as base-material and preparation method thereof, it have nontoxic, pollution-free, do not fire, not quick-fried, safety in utilization good, stable performance, printing adaptability are good, printed matter do after without hazard residue material, nondiscoloration, fade, the characteristics such as cheap for manufacturing cost.Its system's component is filled a prescription as follows by mass percentage:
Above-mentioned wetting agent refers to one or more in sodium laurylsulfonate, polyether modified siloxane, polyether-modified polydimethylsiloxane, natural alcohols wetting agent, and the moisture-resistant that adds wetting agent can improve pigment dyestuff in the consistency, printing ink of pigment and emulsion is wiped and dry rub resistance.
Above-mentioned defoamer refers to organic silicon modified by polyether, and it has froth breaking rapid, the advantage such as press down long and safety non-toxic of bubble time, high temperature resistant, strong basicity resisting is strong.
Above-mentioned flow agent refers to the used for water color ink flow agents such as organosilicon, esters of acrylic acid or organically-modified polydimethylsiloxane solution, product belongs to high reactivity, surfactivity soluble in water, can effectively reduce the surface tension of water-based system, improve the spread ability, enhancement levelling, mobility reach the wettability to ground, prevent the generation of shrinkage cavity, eliminate hand brush trace, improve anti-adhibit quality.
Above-mentioned film coalescence aid refers to monoesters class organic compound, high-carbon alcohol ester organic compound, 2,2,4-trimethylammonium-1,3-pentanediol mono isobutyrate etc., this auxiliary agent can be attracted on emulsion particle, polymerization effectively, the softening emulsion particle that merges, be lowered into film temperature, have good stability to hydrolysis, low zero pour, suitable volatilization efficient, coalescence efficiency efficiently.
Above-mentioned adhesion promoter refers to take titanate coupling agent as main, the water-borne coatings, the water color ink special adhesion promoter that are aided with multiple additives, it can improve water-borne coatings, water color ink to the agglutinating value(of coal) of various base materials, can improve the multiple physicals, vividness, wear resistance of water-borne coatings, water color ink etc. simultaneously.
Above-mentioned pH adjusting agent refers to ammoniacal liquor, can regulate the pH value of water color ink by the addition of ammoniacal liquor, and the pH value of described water color ink can be controlled between 7.0-8.5.
