Abstract
The invention relates to a benzene-free alcohol-resistant PET (polyethylene terephthalate) thermoshrinkable film plastic printing ink which is prepared from 50-75 wt% of solvent, 10-20 wt% of resin, 10-35 wt% of pigment and 1-5 wt% of assistant, wherein the solvent adopts a composite solvent, and is a mixture of ethyl acetate, n-propyl acetate, n-butyl acetate and butanone; the resin is a ternary vinyl chloride-vinyl acetate resin; the pigment adopts a synthetic pigment; and the assistant comprises gas-phase silicon dioxide as an anti-settling agent and polyethylene wax as a lubricating agent. The invention provides a special benzene-free plastic printing ink for a PET thermoshrinkable film. After the ink is matched with the PET thermoshrinkable film for printing, the printing product satisfies the requirement for environmental protection, is safe and nontoxic, can be recycled, has strong alcohol resistance, and well solves the problem of skin packaging in cleaning supplies, cosmetics and other alcohol-containing products.
Description
Technical field
The invention belongs to the plastic printing ink technical field, relate to a kind of with skin packaging material PET (polyester) Shrink Film being PET heat-shrinkable film plastic printing ink of the printing of printed material the anti-alcohol of no benzene that very strong anti-pure ability is arranged and preparation method thereof.
Background technology
Polyester (PET) Shrink Film is a kind of novel Shrink Package material; It has be easy to reclaim, characteristics such as nontoxic, tasteless, good mechanical property, compliance with environmental protection requirements; Its highest percent thermal shrinkage of PET film after the modification by copolymerization can be up to more than 70%; See by skin packaging Development of Materials trend; PET (polyester), OPS environment-friendly materials such as (oriented polystyrene) will progressively replace PVC (SE) heat-shrinkable film in recent years, become the main flow of environmental protection package, be the ideal substitute that replaces the PVC Shrink Film.
The characteristics of PET Shrink Film: it is stable at normal temperatures, shrinks during heating, and is the thermal contraction that takes place in one direction more than 70%.The advantage of heat shrinkable polyester film packing is: 1. fit transparent, embody commodity image.2. tightly restraint packing material, anti-scattered property is good.3. rainproof, moistureproof, mildew-resistant.4. do not have stability, certain antiforge function is arranged.It is its topmost Application Areas that heat shrinkable polyester film is usually used in ready-to-eat, beverage market, electronic apparatus, metal products, particularly shrink label.Because along with the fast development of PET carafe, all need the supporting with it heat-sealing label of doing of PET heat-shrinkable film like carafes such as cola, Sprite, various fruit juice, they belong to polyester, are environment-friendly materials, are easy to the reclaiming utilization.
Aspect printing-ink, there is printing ink manufacturer to produce the special-purpose printing-ink of Shrink Film specially in the market, however the right PVC Shrink Film that is printed on of the basic only limitation of printing ink, and for benzene dissolves printing ink, not enough environmental protection.In addition; Contain in the product skin packaging of pure constituents at some cleaning supplies, makeup etc.; Because the resin of general heat-shrinkable film printing-ink is main with vinyl resin, its anti-pure ability, the product that contains alcohols can dissolve the printing ink on the printed label; Like this, on packing, there is serious defective.Ink product of the present invention is the containing benezene solvent not; Be the special-purpose printing-ink of PET (polyester) Shrink Film; Also fit and be printed on PVC (SE) heat-shrinkable film, adopt the ternary vinyl chloride-vinyl acetate resin simultaneously, overcome the not defective of anti-alcohol of common product as ink vehicle; Printing is soaked in alcohol and was not occurred the printing ink dissolution phenomena in 48 hours, has solved the skin packaging problem of products such as the cleaning supplies that contain pure constituents, makeup well.
Summary of the invention
In order to overcome the above-mentioned shortcoming of prior art
,The present invention provides a kind of PET heat-shrinkable film plastic printing ink that does not have the anti-alcohol of benzene and preparation method thereof
The technical solution adopted for the present invention to solve the technical problems is: a kind of PET heat-shrinkable film plastic printing ink that does not have the anti-alcohol of benzene; Its component comprises solvent, resin, pigment and auxiliary agent; Said solvent adopts combination solvent; This combination solvent is the mixture of vinyl acetic monomer, n-propyl acetate, n-butyl acetate and butanone, and it accounts for the ratio 50～75 of prescription gross weight; Said resin is the ternary vinyl chloride-vinyl acetate resin, and it accounts for the ratio 10～20 of prescription gross weight; Said pigment adopts synthetic dyestuff, and it accounts for the ratio 10～35 of prescription gross weight; As slipping agent, auxiliary agent accounts for the ratio 1～5 of prescription gross weight to said auxiliary agent employing aerosil as anti-settling agent, employing polyethylene wax.
The weight proportion of said combination solvent is that vinyl acetic monomer is 5～15, n-propyl acetate 10～30, n-butyl acetate 15～25, butanone 10～20.
The weight proportion of said auxiliary agent is anti-settling agent 0～3, slipping agent 1～3.
A kind of method for preparing the PET heat-shrinkable film plastic printing ink of the anti-alcohol of above-mentioned no benzene, its process step is:
The first step: earlier vinyl acetic monomer, n-propyl acetate, n-butyl acetate, butanone combination solvent are dropped in the mixing kettle by the prescription requirement; The ternary vinyl chloride-vinyl acetate resin is put in the combination solvent of mixing kettle; Low speed mixing stirred 15～25 minutes through stirrer elder generation; Make material become uniform admixture, high speed dispersion 25～35 minutes to resin dissolves fully again, processes resin liquid;
Second step: pigment, anti-settling agent, slipping agent are put in the resin liquid of mixing kettle, high speed dispersion 25～35 minutes makes pigment, auxiliary agent and resin liquid thorough mixing, processes mill base again;
The 3rd goes on foot: mill base is dropped in the sand mill grind;
The 4th step: mixing colours according to client's color requirement, after quality inspection is qualified, refilter, pack, process product through the mill base that grinds and reach quality standards.
During said high speed dispersion, the stirrer rotating speed is that PM 900～1200 changes.
During said low speed mixing, the stirrer rotating speed is that PM 200～400 changes.
Positively effect of the present invention is: be a kind of special-purpose plastic printing ink of PET heat-shrinkable film that does not have benzene; Printing ink with the supporting printing of PET heat-shrinkable film after; Its printing compliance with environmental protection requirements, safety non-toxic, recyclable; Printing has very strong anti-pure ability, has solved the skin packaging problem of products such as the cleaning supplies that contain pure constituents, makeup well.
