Technical field
The present invention relates to a kind of printing packaging already the intaglio plate composite inks for plastics, particularly a kind of composite alcohol water plastic printing ink and preparation method thereof of usefulness.
Background technology
In recent years, along with the packaging industry develop rapidly, plastic gravure printing ink market also constantly increases, current China is in the printing of plastics film, gravure has the incomparable distinctive feature in other printshop, particularly should have on food and medicine packing, gorgeous in the color that the food shelf in each emporium, supermarket are being put, packing is novel, a feast for the eyes various food all adopt is plastics intaglio printing packing, the packages printing of these plastics is inseparable with people's life.Simultaneously, because the raising of human consumer's environmental consciousness, they are to the security of packages printing, the feature of environmental protection is extremely paid close attention to, traditional plastic printing ink is oiliness and pure dissolubility, although dissolvent residual has been done strict demand, but also there are injury and the influence of seal back dissolvent residual peculiar smell and the security problems of food that HUMAN HEALTH is produced, receive the concern of country, country put into effect a GB/T10004-2008 standard and the food safety method disabled to the aromatic solvent of similar toluene in the food product pack printing, other developed countries also have relevant environmental protection law to control the release of volatile organic compounds; At present, abroad agricultural byproducts, the food pack printing ink to China's outlet has clear and definite regulation, directly requiring employed printing ink must be water-soluble printing ink, therefore, improve the packages printing quality and become the important channel that commodity improve the market competitiveness and improve added value, along with society more and more pays close attention to the security of food, agricultural-food and daily necessities packing, will be more and more higher also to the requirement of packing.For adapting to the social development demand,, will inevitably require to use " Green Packaging and green printing ink " to manage to reduce pollution and destruction to environment.
Summary of the invention
The objective of the invention is to provide a kind of and can reduce environmental pollution for the deficiency that solves above-mentioned technology, security is good, printability is good, composite alcohol water plastic printing ink of environmental protection and preparation method thereof.
In order to achieve the above object, a kind of composite alcohol water plastic printing ink provided by the invention, it comprises modified acroleic acid copolymer resins, modification aldehyde ketone resin, dispersion agent, pigment, modified polyester resin, adhesion promoter and ethanol, the weight part content that it is characterized in that each component is respectively 15 parts～45 parts of modified acroleic acid copolymer resinses, 2 parts～10 parts of modification aldehyde ketone resins, 2 parts～5 parts of dispersion agents, 8 parts～35 parts of pigment, 6 parts～10 parts of modified polyester resins, 1 part～4 parts of adhesion promoters, 20 parts～40 parts of ethanol.The molecular-weight average of described modified acroleic acid copolymer resins is 8000～100000, and described modified acroleic acid copolymer resins is the polyurethane-modified acrylic acid copolymer resins.Described modified polyester resin is an acrylic ester modified polyester resin.Described ethanol is the ethanol of content 95%; Described dispersion agent is BYK-220S; Described adhesion promoter is the high connection of titanic acid ester agent HW-801.
Selection of pigment of the present invention is an example with the Wuyuan of printing usefulness, white pigment can be selected the titanium dioxide of rutile-type for use, as C.I.Pigment White 6, black pigment can be selected carbon black for use, as C.I.Pigment Black 7, yellow ultramarine can be selected diarylide yellow for use, as C.I.Pigment Yellow 14, red pigment can select for use azo lake red, as C.I.PigmentRed 57:1, blue pigments can be selected phthalocyanine blue for use, as C.I.Pigment Blue 15:4.
A kind of preparation method according to above-mentioned described composite alcohol water plastic printing ink provided by the invention is characterized in that adopting following step:
A), pre-dispersed, modified acroleic acid copolymer resins, modification aldehyde ketone resin, modified polyester resin, dispersion agent, ethanol are joined respectively in the pre-mixing dispersion cylinder by the 1/3-2/3 of formula rate, starting dispersion machine stirs it, the pigment, the adhesion promoter that in whipping process, add formula ratio then gradually, the reinforced back that finishes is opened dispersion machine and is stirred, high speed dispersion is wetting fully so that pigment is carried out, and makes pre-dispersed mill base to be ground;
B), grind to disperse, pre-dispersed mill base is undertaken finely divided by grinding plant, the aggregate that separates pigment with external force makes it to become the fineness≤15 μ m that meet ink technique and require, thereby obtains dispersible pigment color paste;
C), allotment, modified acroleic acid copolymer resins liquid, modification aldehyde ketone resin liquid, modified polyester resin liquid, dispersion agent, the ethanol of remainder are joined in the dispersible pigment color paste, starting high speed dispersor stirs even with abundant dispersing and mixing, and then viscosity, the form and aspect of printing ink are adjusted, thereby reach predetermined specification of quality, make finished product printing ink;
D), purify packing, remove mechanical impurity and coarse grain by filter plant, then packing.
At this, described modified acroleic acid copolymer resins can be the polyurethane-modified acrylic acid copolymer resins, the production method of described polyurethane-modified acrylic acid copolymer resins is to utilize at first that polyether Glycols and vulcabond are synthetic to be had-base polyurethane prepolymer for use as of NCO group, its reaction process as the formula (1):
(n+1) OCN-R-NCO+nHO-R ’ Period H → OCN-(RNHCOOR ' OCONH) nR Tun CO
Utilize decompression that polyether Glycols is distilled, the base polyurethane prepolymer for use as that obtains further reacts with hydroxyl acrylic and generates two ends the end capped polyurethane acroleic acid performed polymer of vinylformic acid is all arranged, its reaction process as the formula (2):
OCN～NCO+2CH
2＝CHCOOCH
2CH(CH
3)OH→CH
2＝
CHCOOH
2CH(CH
