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 and a kind ofly to take the printing that skin packaging material PET (polyester) heat-shrinkable film is printed material, the heat-shrinkable film of the PET without the anti-alcohol of benzene plastic printing ink of very strong anti-pure ability and preparation method thereof is arranged.
Background technology
Polyester (PET) heat-shrinkable film is a kind of Novel hot shrink wrap material, it has and is easy to reclaim, nontoxic, tasteless, good mechanical property, meets the characteristics such as environmental requirement, its the highest percent thermal shrinkage of PET film after modification by copolymerization can be up to more than 70%, development trend by the skin packaging material is seen, the PET(polyester), the environment-friendly materials such as OPS (oriented polystyrene) in recent years by replacing PVC(polyvinyl chloride) heat-shrinkable film, becoming the main flow of environmental protection package, is the ideal substitute that replaces the PVC heat-shrinkable film.
The characteristics of PET heat-shrinkable film: it is stable at normal temperatures, shrinks during heating, and is the thermal contraction occurred 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. without Restoration, 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 beverage bottle, as the beverage bottles such as cola, Sprite, various fruit juice all need the PET heat-shrinkable film supporting heat-sealing label of doing with it, they belong to polyester, are environment-friendly materials, are easy to the reclaiming utilization.
Aspect printing-ink, have in the market Printing ink producing producer to produce specially the printing-ink of heat-shrinkable film special use, yet printing ink substantially only limits to printability in the PVC heat-shrinkable film, and be the molten printing ink of benzene, environmental protection not.In addition, in the product skin packaging that contains pure constituents at some cleaning supplies, makeup etc., because the resin of general heat-shrinkable film printing-ink be take acrylic resin as main, its anti-pure ability, product containing alcohols can dissolve the printing ink on printed label, there is like this, on the packaging serious defect.Ink product of the present invention is the containing benezene solvent not, for the PET(polyester) the special-purpose printing-ink of heat-shrinkable film, also printability is in the PVC(polyvinyl chloride) heat-shrinkable film, adopt the ternary vinyl chloride-vinyl acetate resin as ink vehicle simultaneously, overcome the not defect of anti-alcohol of common product, printing is soaked and the printing ink dissolution phenomena within 48 hours, do not occurred in alcohol, has solved well the skin packaging problem of the products such as the cleaning supplies that contain pure constituents, makeup.
Summary of the invention
In order to overcome the above-mentioned shortcoming of prior art
,the invention provides a kind of heat-shrinkable film of the PET without the anti-alcohol of benzene plastic printing ink and preparation method thereof
The technical solution adopted for the present invention to solve the technical problems is: a kind of heat-shrinkable film of the PET without the anti-alcohol of benzene plastic printing ink, its component comprises solvent, resin, pigment and auxiliary agent, described 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 formula gross weight; Described resin is the ternary vinyl chloride-vinyl acetate resin, and it accounts for the ratio 10～20 of formula gross weight; Described pigment adopts synthetic dyestuff, and it accounts for the ratio 10～35 of formula gross weight; Described auxiliary agent employing aerosil is as anti-settling agent, employing polyethylene wax as slipping agent, and auxiliary agent accounts for the ratio 1～5 of formula gross weight.
The weight proportion of described combination solvent is that vinyl acetic monomer is 5～15, n-propyl acetate 10～30, n-butyl acetate 15～25, butanone 10～20.
