Abstract
The invention discloses gravure printing ink for a poly(ethylene terephthalate) (PET) base material and a preparation method for the gravure printing ink, and aims to provide ink having the advantages of good fluidity, high adhesion, high gloss, simple and feasible preparation method, safe use and environment friendliness, and a preparation method thereof. The ink comprises the following components: an organic pigment or an inorganic pigment, resin, an adhesion promoter, a dispersing agent and the balance of organic mixed solvent. The ink is prepared by the following steps of: mixing dimethyl carbonate, ethyl acetate and n-propyl alcohol to obtain a mixed solvent, and dissolving the resin; and mixing with the organic pigment or the inorganic pigment, stirring and dispersing to obtain a semi-finished product of color paste, fully grinding on a sand mill, adding the adhesion promoter and the dispersing agent, fully stirring, and filtering off components of which the fineness is more than 15mu m by using a filtering machine to obtain the gravure printing ink for the PET base material.
Description
Technical field
The present invention relates to a kind of printing ink and preparation method thereof, particularly a kind of the recessed of PET base material that be used for
Painting plate ink and preparation method thereof.
Background technology
At present, people not only have been confined to its aesthetic property to the pursuit of commodity outer packaging, but more and more pay attention to the safety performance and the environmental-protecting performance of its packing.Present stage commodity outer packaging mostly uses is PET film composite print; The printing ink solvent that uses deleterious benzene kind solvents such as the benzene,toluene,xylenes etc. of adopting, the printing ink solvent residual quantity of using this solvent more greatly, benzene class content overproof especially.This toxic solvents of the long-term contact of people can be to human body, and particularly neural system causes very big injury.China in the light industry standards QB/T2929-2008 forth in benzene, toluene, xylene residual sum of ≤ 3 ?
, solvent residue sum ≤ 10
.Therefore, a kind of technical scheme that can substitute or reduce the benzene kind solvent use of research is necessary.
Summary of the invention
The objective of the invention is to avoid the use of benzene kind solvent, provide that a kind of good fluidity, strong adhesion, glossiness are high, the preparation method is simple and gravure printing ink and method of manufacture thereof safe in utilization, environmentally friendly, that be widely used in the PET base material.
The present invention adopts following technical proposals: a kind of gravure printing ink that is used for the PET base material; Contain ink by weight than being 9.5%～11.5% pigment dyestuff or 28%～32% mineral dye; 28%～43% resin; 9%～13% adhesion promoter; 0.5%～1% dispersion agent, all the other are organic mixed solvent.
Above-mentioned organic mixed solvent be in methylcarbonate, ethyl acetate, the n-propyl alcohol a kind of or its bonded any one.Adopt this kind mixed solvent not only to reduce the printing ink production cost, and can effectively reduce the environmental pollution that causes because of traditional benzene kind solvent volatilization.Organic mixed solvent can be that 35%～60% methylcarbonate, 25%～47% ethyl acetate, 14%～18% n-propyl alcohol are formed by weight ratio also.
Above-mentioned resin adopts polyurethane solution, and resin solid content accounts for 28%～43% of total ink.
For improving the adhesive ability of printing ink to the PET material, need in printing ink, add adhesion promoter, above-mentioned adhesion promoter adopts vinyl chloride-vinyl acetate resin, claims E-wax again.
Above-mentioned dispersion agent is that polyethylene wax (claiming PE wax, 3620 again) is a kind of special have concurrently wetting and additive dissemination; It can reduce pigment and the surface tension that is connected between material; Improve their wetting ability; Can strengthen the grinding effect of printing ink; Reduce jitter time; Particularly carbon black, phthalocyanine blue there are outstanding dispersion effect, keep printing ink well mobile.
According to the different above-mentioned pigment dyestuff of required ink color can select in phthalocyanine blue, bright red 57:1, diarylide yellow, the 99R import carbon black any or several.Mineral dye can be selected titanium dioxide for use, produces the gravure printing ink that is used for the PET base material of corresponding color.。
The present invention also provides a kind of preparation method of gravure printing ink of the PET of being used for base material: (1) is mixed and made into mixed solvent with methylcarbonate, ethyl acetate and n-propyl alcohol.(2) with above-mentioned mixed solvent dissolving resin, process the resin diluent.(3) pigment dyestuff or mineral dye are mixed with above-mentioned resin diluent, dispersed with stirring makes the work in-process mill base.(4) use the fully grinding on sand mill of work in-process mill base.(5) to wherein adding adhesion promoter and dispersion agent, fully stir.(6) above-mentioned printing ink is filtered on filter, behind the composition of filtering fineness greater than 15 μ m, promptly get the gravure printing ink finished product that is used for the PET base material.
In sum, adopt above-mentioned material proportion and making method, the present invention has following effect: owing to adopted the toxic organic solvent substituted benzene solvent that do not have that raw material is easy to get, make the use and the production safety, environmentally friendly of printing ink; Owing to adopted vinyl chloride-vinyl acetate resin, improved the adhesive ability of printing ink to the PET material; Have concurrently wetting and additive polyethylene wax dissemination owing to adopt; Improved the wetting ability of printing ink; Strengthened the grinding effect of printing ink; Reduce jitter time; Particularly carbon black, phthalocyanine blue there is outstanding dispersion effect; Keep printing ink well mobile, make the ink degree of producing high.Be applicable to the PET material to be that the intaglio printing and its preparation method of carrier is simple.
