Abstract
The invention discloses an acid dye gravure printing ink, which comprises the following components and weight percentages: acid dye 15 to 20 percent, bonding material 20 to 30 percent, solvent 50 to 64 percent, defoaming agent 0.3 to 0.5 percent, and leveling agent 0.3 to 0.5 percent. The preparation steps comprise dye pre-dispersing, color paste grinding and ink preparation. The invention has the advantages that: 1. because the invention uses ethanol with strong polarity as solvent, the ink has good adaptability with PET film and BOPP film; 2. the invention is not only the high quality gravure printing inks, but also the acid dye printed on the PET film or BOPP film has best transferring performance in hygrometric state, so the invention is suitable for wet cold transfer printing process; 3. the invention realizes to transfer printing without paper, so that the frost is protect, large amount of paper used for transferring the printing is avoided, and wood consumption is reduced, and also waste water generated in making paper is reduced; 4. the invention is in simple preparation method and low cost.
Description
Technical field
The present invention relates to a kind of with the matching stain be the gravure printing ink of tinting material, especially this ink printing in the PET film or after above the BOPP film, can under the wet method state, shift at real silk, on nylon or the wool fabric.
Background technology
Transfer printing all uses dispersed dye to pass through the characteristics that distil when high temperature at present, is used for hydrophobic fibers such as terylene.Because the technology that transfer printing combines with printing in textiles for printing, resulting colored type is meticulous, can print photograph effect pattern, and non-common stamp mode can obtain.In addition, the transfer printing less investment, technology controlling and process is simple, and three waste discharge is few, is environmental protection technology.So it is the research focus that transfer printing is applied to wool, real silk, corium and nylon facing material always.And prior art all is confined to handle for carry out graft modification with upper fabric in order to finish the transfer printing of above fiber, again by the hot transfer printing of 200 degree.Yet, after handling through modification, all lost original water-wet behavior, particularly corium and nylon facing material can not bear high temperature with upper fabric.
Summary of the invention:
Goal of the invention: the objective of the invention is at the deficiencies in the prior art, provide a kind of and can realize protein fibre and the employed acid dye intaglio printing ink of nylon fiber transfer printing smoothly.
Another object of the present invention provides a kind of method for preparing above-mentioned acid dye intaglio printing ink.
Technical scheme: acid dye intaglio printing ink of the present invention is characterized in that it comprises following component and weight ratio: matching stain 15-20%, be connected material 20-30%, solvent 50-64%, defoamer 0.3-0.5%, flow agent 0.3-0.5%.
The present invention is the preparation of acid dye intaglio printing ink, be that the matching stain that will go up fibers such as dyeing silk, wool, corium and nylon is made the printing ink of intaglio printing, by gravure printing machine with this ink printing on PET or BOPP film, shift seal by wet method again, with design transfer on the lining of undertaking the printing of.
Wherein matching stain is a dyestuff of making a general reference can print and dye protein and nylon fiber under acidic conditions, and it comprises strongly-acid dyestuff, weak acid dye, neutral dye, acidic complex dye, acid mordant dye.
The present invention selects for use solid-state polyamide resin as connecting material, and the molecular weight of polyamide resin is to be formed by dimerization vegetable fatty acids and the polycondensation of polyethylene polyamine class between 500-9000, and this type of polyamide resin is non-reacted thermoplastic resin.
Solvent of the present invention is mainly selected nontoxic ethanol for use, and ratio is according to temperature height, seasonal variation and difference.Add a small amount of low toxicity methylethylketone, or diacetone alcohol is regulated the rate of drying of printing ink.
Defoamer can be a silicone antifoam agent.Such as organopolysiloxane, effect is: can reduce the surface tension of liquid effectively, have excellent defoaming effect.
Flow agent can be the organosilicon flow agent.Such as polyether-modified organopolysiloxane, effect is: the surface tension that can obviously reduce coating system, thereby improve the wettability of printing ink, have significant levelling, enhanced shine and smooth preferably effect, can eliminate the lacquer disease of types such as shrinkage cavity, pinprick, crater ground.
The preparation method of acid dye intaglio printing ink of the present invention may further comprise the steps:
1, dyestuff is pre-dispersed: solvent (as ethanol) is placed agitator, at temperature 45-55 degree, slowly add linking agent (as polyamide resin) during stirring at low speed, dissolve fully until linking agent, add flow agent, defoamer again, stir (approximately 5-10 minute), slowly add matching stain again, (stirring velocity is brought up to about 1200-1500 rev/min in stirring, 30-45 minute), the test color slurry viscosity replenishes adding solvent (as ethanol), regulate viscosity to moderate (approximately 1300-1500 centipoise, i.e. 40 degree).
2, mill base grinds: the mill base that step 1 is prepared, place grinding in ball grinder, and keep grinding about 48-72 hour, make the mill base fineness be less than or equal to 1 micron.
3, configuration printing ink: step 2 gained printing ink is emitted, regulate viscosity to moderate (about 50 seconds, i.e. Zan Shi 2# cup, 25 spend) with the mixture of ethanol or ethanol and methylethylketone or diacetone alcohol.
Beneficial effect: the present invention compared with prior art, its remarkable advantage is: 1 owing to mainly adopted strong polar ethanol to make solvent, makes that printing ink and PET film and BOPP film printing adaptability are good.2, the present invention is not only high-quality gravure ink, and the matching stain that is printed on PET film or the BOPP film has splendid transitivity when hygrometric state, is adapted to the cold transfer printing process of wet method.3, realize no paper transfer printing, conserved forests, avoided a large amount of paper of traditional transfer printing, effectively reduced lumber consumption, reduced the waste water that produces because of papermaking in a large number simultaneously.4, preparation is simple, and cost is lower.
