Abstract
The invention relates to water-based gravure pearly lustre varnish and a preparation method thereof. The water-based gravure pearly lustre varnish is prepared from the following main raw materials: ethyl alcohol, acrylic resin, ethanol amine, styrene-acrylic copolymer emulsion, a defoaming agent and isopropyl alcohol. The water-based gravure pearly lustre varnish has the advantages that different components are added in different sequences, high-speed dispersion is carried out, the varnish has good dispersion performance, viscosity of the pearly lustre varnish is reasonably controlled, adhesion is good, and the varnish has good flowability; meanwhile, ethanol amine and isopropyl alcohol are utilized for controlling the viscosity of the varnish, so that the water-based gravure pearly lustre varnish is not layered in pearlescent printing ink when being used, pearly lustre and glossiness are improved, and stability is good; during printing, diluent release property is good, and printing product residue is extremely low, so that the water-based gravure pearly lustre varnish can be widely applied to printing by virtue of a cast coating cardboard, glass copper plate paper, ivory board, copper plate paper, gold and silver cards and hologram paper printing, and the VOC requirement during cigarette packaging can be met; and meanwhile, cost is low, less smell is produced, and no harm is done to human beings.
Description
Technical field
The present invention relates to a kind of water-based gravure pearly-lustre stand linseed oil, that be specifically related to a kind of environmental protection, that a kind of applicable highspeed gravure prints water-based gravure pearly-lustre stand linseed oil and preparation method thereof.
Background technology
Sheet package printing batch is large, require high, take intaglio printing mode in a large number, printing-ink is in press primarily of stand linseed oil and the glossiness blending oil composition of tool, stand linseed oil vegetables oil is aggregated to certain viscosity or adds synthetic resins wherein, be modulated into the ink with suitable viscosity, for printing.Pearl ink is that one of three large optical interference ink all can print in paper material and plastic material, some high-grade cigarettes, Wine packaging often adopt this specialty inks printing, pearl ink mainly adopts pearly pigment, and forms thin layer on printed layers surface, forms pearly-lustre phenomenon by light.In the adjustment of pearl ink, stand linseed oil just has vital role, and the conventional ester molten vinylformic acid solvent-borne type pearly-lustre stand linseed oil that uses prints, but its stickiness is high, and mobility is less, can not meet the floatability requirement of pearly pigment.Simultaneously along with the national development of low-carbon environment-friendly needs and the proposition of packaging industry VOC and softening agent index request, solvent type photogravure pearly-lustre stand linseed oil more and more can not adapt to above requirement, the water-based stand linseed oil of environment-friendly type will replace solvent-borne type stand linseed oil.
Publication number is the production method that the Chinese invention patent of CN104073058B discloses a kind of plastic flexible package aqueous intaglio printing ink, the stand linseed oil wherein adopted mainly consists of water-base resin liquid, NeoCeylA-1120 ACRYLIC EMULSION, NeoPacE-200 polyurethane acroleic acid, propylene glycol monomethyl ether, Monoethanolamine MEA BASF, W-18 aqueous dispersant, NeoRezR-650 aliphatic polyurethane dispersion liquid, W-0506 defoamer, deionized water, ethylene glycol, its preparation method is dropped in Scattered Kettle by each material to be uniformly dispersed and to get final product.Use polyurethane acrylic resin, rate of drying is slow, and be not suitable for paper printing, on paper, transfer effect is bad.
Summary of the invention
The present invention proposes water-based gravure pearly-lustre stand linseed oil, this pearly-lustre stand linseed oil, when modulating pearl ink, makes ink have good pearly-lustre and stability, and connect high adhesive ability, pearl effect is good, and glossiness is good, and not network blocking, print speed is fast.
Invention further provides a kind of preparation method of water-based gravure pearly-lustre stand linseed oil, adopt the different order of different piece to add, high speed dispersion, can make stand linseed oil dispersing property good, carries out conservative control to the viscosity of pearl ink, and mobility is large, and tack is good.
A kind of water-based gravure pearly-lustre stand linseed oil, it is primarily of following A, B, C tri-part material composition:
A: water 13-17%, ethanol 9-12%, Virahol 3-5%, acrylic resin 23-30%, thanomin 5.5-7.5%;
B: latex of copolymer in cinnamic acrylic ester 15-30%, defoamer 0.3%, thanomin 0.2%;
C: water 8-10%, ethanol 6-9%, thanomin 0.2%.
Water soluble acrylic resin described above is thermoplastic propene's acid esters class, and molecular weight is 180000-200000, has good photostabilization and resistance of aging.
Latex of copolymer in cinnamic acrylic ester in above-mentioned part B is a high score prose style free from parallelism, and have the emulsion of high viscosity, high thixotropic, particle diameter is fine, and cohesive force is strong, and ageing resistance is excellent, good stability.Do not add thixotropic agent, namely have certain thixotropy, there is excellent water tolerance, alkali resistance and wear resistance.Described defoamer is polyether silicone copolymerized polymer.
A preparation method for water-based gravure pearly-lustre stand linseed oil, comprises the following steps:
(1), prepare burden pre-dispersed: by the water of part A, ethanol, Virahol, water soluble acrylic resin, thanomin mixing, drop into high speed dispersor, adjusting rotary speed and time dissolve;
(2) by part B latex of copolymer in cinnamic acrylic ester, defoamer, thanomin drops into high speed dispersor, and adjusting rotary speed and time disperse;
(3), stand linseed oil adjustment: C part thanomin is added and adjusts between pH value to 8.0-9.0, add ethanol, water solvent adjusting viscosity, obtained pearly-lustre stand linseed oil finished product.
Further, when carrying out first dispersion, redispersion in described step (1), wherein arranging rotating speed in high speed dispersor is 1100-1300 rev/min, and jitter time is 50-90 minute.
Further, when carrying out first dispersion, redispersion in described step (1), wherein arranging rotating speed in high speed dispersor is 1200 revs/min, and jitter time is 60 minutes.
Further, in described step (2), during dispersion, high speed dispersor rotating speed is set to 700-800 rev/min, and jitter time is 25-40 minute.
Further, in described step (2), during dispersion, high speed dispersor rotating speed is set to 700 revs/min, and jitter time is 30 minutes.
Further, in described step (3), during dispersion, high speed dispersor rotating speed is 700 revs/min, and jitter time is 30 minutes.
Further, in described step (3), during dispersion, high speed dispersor rotating speed is 700 revs/min, and jitter time is 30 minutes.Regulate viscosity to the viscosity of standard-required, being usually adjusted to No. 4 flow cup elution times of coating controls at 20-25 second (at 25 DEG C), and the too low golden ink print unfairness of viscosity, glossiness is low, metal sense is poor; The black poor adhesion of the too high gold of viscosity, hachure transfer difference easily breaks.Under this viscosity, blending oil can better and oily matter merge, the gold ink glossiness simultaneously adjusted and metal sense good.
A kind of water-based gravure of the present invention pearly-lustre stand linseed oil and preparation method thereof, its beneficial effect is:
