Abstract
The invention relates to the technical field of ink, in particular to flexographic food packaging ink and a preparation method thereof. The flexographic food packaging ink comprises the following components in percentage by weight: 25 to 55 percent of acrylic resin, 5 to 25 percent of alkali-soluble resin, 0.2 to 1 percent of defoaming agent, 1 to 8 percent of polyethylenewax, 0.1 to 1 percent of flatting agent and 10 to 25 percent of organic pigment and water. The flexographic food packaging ink has the advantages of simple preparation, low cost, environmental protection, nontoxicity, stable performance, light air pollution, and no residual toxic solvent, is favorable for safety production and environmental protection, particularly has good luster and wear resistance, and is not decolored after being soaked in 60 DEG C hot water for 2 hours.
Description
Technical field:
The present invention relates to technical field of ink, relate in particular to a kind of flexographic food packaging ink and preparation method thereof.
Background technology:
The Along with people's growth in the living standard is also had higher requirement to food product pack, and wherein the use of printing ink in packing is especially noticeable.Printing ink not only will satisfy and enrich beautiful attractive, decorative effect as printing material, but also will satisfy the requirement of various different qualities, like nontoxic, heat-resisting, cold-resistant, anti-solvent, oil resistant, rub resistance etc.Internationally recognized food printshop must be observed with printing ink does not have the principle that shifts; Must not use conventional printing ink during the printing of food packaging article internal surface; The solvent that manufacturer must guarantee to print in the printing ink of back of undertaking the printing of all volatilizees, and reaches the respective standard of application industry.
Benzene dissolubility Chlorinated Polypropylene III printing ink is the widest printing ink that is mainly used in the food product pack printing of current use face.Such printing ink is to make and use technology comparative maturity all, though good, the fast drying of the post-press finishing performance of this printing ink, but have a lot of deficiencies: the relative toxicity as owing to toluene is bigger, and the residual solvent value of printed matter is higher; Because the poor heat stability of Chlorinated Polypropylene III, produce with storage process in, be prone to discharge chlorine and form hydrogenchloride, make printing ink be stronger acidity, to the serious problems such as corrosion of printing plate cylinder generation; And the benzene soluble ink can damage the ozone layer, and in use also can work the mischief to workers'health and safety, and remain in the residue in the packing articles, can cause pollution to a certain degree to the food in packing under certain condition.So forbid or control the printing ink of use aromatic solvent in succession in European and some developed countries.Therefore, developing the printing ink that meets environmental protection and food sanitation requirement is problem anxious to be solved.
Require printing ink neither to pollute, operative employee author's health is not worked the mischief again, but also can not damage food in the packing environment.
These people have been carried out big quantity research, and water color ink is the printing ink that the gentle version of overwhelming majority packages printing is both at home and abroad at present adopted, and it is mainly processed through multiple grinding by water soluble resin, pigment dyestuff, solvent and relevant auxiliary agent.Water soluble resin is the low-melting ink vehicle of water color ink; The domestic water soluble propene's acid modified resin of often selecting for use is made low-melting ink vehicle; Its thermotolerance, weathering resistance, chemical resistant properties, anti-pollution and glossiness etc. all have significant advantage, and no matter directly dispersing and dissolving still is the synthetic macromolecule emulsion, all shows good performance; Water color ink does not contain volatile organic solvent; Not only can reduce the residual toxicity of printing, and can prevent to catch fire because of static contacts with flammable solvent, be a kind of novel " environmental protection " printing-ink; Wherein, The one Chinese patent application file; Application number is: 200510031669.8 file disclose a kind ofly be used for food product pack, medicine tablet, wine label packing goes up the aqueous aluminum foil ink of printing, it is formulated by aqueous polyurethane, tensio-active agent, aqueous color paste, skimmer, water; The one Chinese patent application file, application number is: 99116261.7 file also discloses a kind of base ink for intaglio printing on aluminium foil and preparation technology thereof of usefulness of the pure aluminum foil base material printing that is suitable on high speed intaglio process machine, doing the luxury food packing; It is by synthetic resins, and organic solvent adds pigment again after low-melting ink vehicle is fused in heating; Batchings such as auxiliary agent through disperseing, are ground; Color matching, packing, and make; But, still have unsettled deficiency under the comparatively high temps.
Summary of the invention:
One of the object of the invention is the deficiency to prior art, and discloses a kind of good glossiness that not only has, and environmental protection, especially can tolerate the flexographic food packaging ink of comparatively high temps.
Two of the object of the invention is to provide the preparation method of above-mentioned flexographic food packaging ink.
The objective of the invention is to be achieved through following method:
A kind of flexographic food packaging ink; Comprise following raw materials by weight percent:
Vinyl resin 25%～55%
Alkali soluble resins 5%～25%
Skimmer 0.2%～1%
Polyethylene wax 1%～8%
Flow agent 0.1%～1%
Pigment dyestuff 10%～25%
Water 20%～60%.
A kind of flexographic food packaging ink; Comprise following raw materials by weight percent:
Vinyl resin 35%～45%
Alkali soluble resins 10%～20%
Skimmer 0.2%～0.5%
Polyethylene wax 3%～5%
Flow agent 0.5%～1%
Pigment dyestuff 15%～20%
Water 45%～55%.
Wherein, described alkali soluble resins is a styrene acrylic resin.
Described skimmer is a mineral oil defoaming agent.
Described flow agent is the polyacrylic flow agent.
Described skimmer is a dimethylsilicone oil.
The preparation method of above-mentioned a kind of flexographic food packaging ink: alkali soluble resins, water, pigment dyestuff, skimmer, polyethylene wax and the flow agent with above-mentioned amount mixes earlier, gets mixture A; Use sand mill that mixture A is milled to the mix powder B that fineness is 2～10um again; Then add the vinyl resin of said amount, and stir, make product at last toward mix powder B.
Wherein, the fineness of described mix powder B is 4～6um.
Pigment dyestuff is mainly the one or more combination thing among Phthalocyanine Blue BGS, benzidine yellow G R, permanent yellow 2GS or the solid forever pink FBB.
The invention has the beneficial effects as follows, the present invention includes vinyl resin, alkali soluble resins, skimmer, polyethylene wax, flow agent, pigment dyestuff and water; The present invention is primary solvent with water; Not only excellent, pliable and tough good, printing soft and smooth property of good, the sliding property of print gloss and the penetrating light of color, and it is good to have good glossiness and resistance to abrasion, especially resistance toheat; Can anti-60 ℃ of hot water 2h nondiscolorations, can satisfy the requirement of high-grade printing; The present invention prepares simply, cost is lower, environment-protecting asepsis, stable performance, residual to low, the no noxious solvent of topsoil, help safety in production and environment protection.
