Description
Technical Field
The invention relates to the technical field of fine chemical engineering, in particular to ink for tipping paper printing and a preparation method thereof.
Background
Tipping paper, also known as tipping paper, is an important wrapper on cigarettes for connecting the cigarette to the filter portion, and the surface of tipping paper usually requires printing, stamping, perforating and other processing steps, with the printing process providing a personalized pattern on the surface of tipping paper.
In the prior art, a large amount of pigment components are usually added into the ink for printing on the surface of tipping paper, so that the ink has good color fullness and coverage, and the printing attractiveness is improved, but more pigments can greatly increase the cost of the ink on one hand, and meanwhile, the pigment can reduce the fluidity of the ink, so that the difficulty of gravure printing is improved, and especially when the cost of the pigment is relatively large for some ink adopting customized colors, the pigment consumption can bring more influence on the whole cost of the ink.
In order to reduce the difficulty of gravure printing and simultaneously reduce the cost ratio of pigment parts, there is a need for an ink for tipping paper printing which has a small pigment usage and good color fullness and hiding power.
Disclosure of Invention
In view of the above, the present invention provides an ink for tipping paper printing and a preparation method thereof, which aims to reduce the pigment usage ratio and maintain good color fullness and hiding power.
The technical scheme of the invention is realized as follows: the invention provides tipping paper printing ink which is characterized by comprising the following raw materials in parts by weight: 20-25 parts of aqueous acrylic resin, 2-3 parts of diisobutyrate dioxide, 1-2 parts of nonpolar pigment and 2-2.5 parts of emulsifier.
In the conventional printing ink, the pigment content is usually 15-40% of the total mass of the ink, and some of the pigment content is even more than 50% of the total mass of the ink, which brings great challenges to the gravure printing ink on the surface of tipping paper, and the printability can be improved by directly reducing the pigment content, but the printing color effect is reduced due to the reduced covering power of the pigment after the pigment content is reduced in an ink dispersion system, and the main reason is that the pigment particles with too high solvent content in the dispersion system are not uniformly distributed on the printing surface, however, the pigment is sufficiently spread on the whole printing surface from the practical use amount, and the main reason for the reduced covering power is that the pigment is unevenly distributed at different positions along the direction perpendicular to the printing surface, the partial pigment is not excessively distributed, and the partial pigment is little in the partial region, so that the covering power is met, and the problem can only be solved by integrally improving the pigment content.
Different from the thinking, the invention adopts two mixed solvent dispersion systems with different polarities, the mixed solvent dispersion systems are emulsified by an emulsifier, but the pigment adopts nonpolar pigment, the dosage of nonpolar diisobutyrate is less, at the moment, the pigment dispersed in diisobutyrate has higher concentration, after the emulsification system is printed, the diisobutyrate gradually floats on the surface of the dispersion system, the nonpolar pigment dispersed therein floats upwards to form a high-concentration dispersion system layer with pigment, the water-soluble acrylic resin has higher density, and the water-soluble acrylic resin is sunk and attached on the surface of tipping paper, and in the subsequent curing process, the diisobutyrate is volatilized to only remain nonpolar pigment, and the pigment concentration in the nonpolar pigment dispersion system is high, the color saturation is high, but the pigment dosage is extremely small due to the instability and the similar solubility of the dispersion system.
In some embodiments, the emulsifier is diethylene glycol esterethylamine.
In order to enable the printed ink dispersion system to quickly form the expected layering effect, the application adopts diethylene glycol ester-based ethylamine, and experiments prove that the emulsifier has the best use effect, and the printed pigment dispersibility saturation and coverage are good.
In some embodiments, the non-polar pigment comprises: graphite, titanium dioxide, lead white, chrome yellow, red iron yellow, cobalt blue and the like.
In some embodiments, the non-polar pigment is prepared from a non-polar pigment having a particle size of 20-80nm and a non-polar pigment having a particle size of 400-600nm in a ratio of 10: (1-3) and mixing.
The main purpose of using graded nonpolar pigments is to further increase the color saturation and masking force.
In some embodiments, the nonpolar pigment having a particle size of 20-80nm is obtained by a surface treatment process comprising: exposing nonpolar pigment with particle size of 20-80nm to low temperature oxygen plasma atmosphere for 3-6s.
In the above embodiment, the low-temperature oxygen plasma treatment is performed on the nonpolar pigment with smaller particle size, so that the nonpolar pigment has certain affinity to the aqueous acrylic resin, and in a dispersion system formed after printing, the small-particle-size nonpolar pigment subjected to the low-temperature plasma surface treatment is easier to disperse to one side surface of the diisobutyrate phase, which is close to the aqueous acrylic resin phase, so that the spreading and dispersing of the small-particle-size nonpolar pigment are facilitated, the covering power is improved, and layering distribution is formed between the small-particle-size nonpolar pigment and the large-particle-size nonpolar pigment, so that the color fullness is facilitated to be improved.
In some embodiments, the non-polar pigment having a particle size of 20-80nm is exposed to a low temperature oxygen plasma atmosphere for an exposure time of 4.5 seconds.
The low-temperature plasma surface treatment time has a great influence on the affinity of the nonpolar pigment to the aqueous acrylic resin phase, if the treatment time is insufficient, the affinity is insufficient, the spreading effect is poor, and if the treatment time is too long, the dispersibility of the nonpolar pigment is possibly too strong, so that the spreading effect cannot be achieved, and finally, the color saturation and the hiding power are greatly reduced or even disappear.
In some embodiments, the non-polar pigment is mixed from a non-polar pigment having a particle size of 50nm and a non-polar pigment having a particle size of 500nm in a ratio of 5:1.
In some embodiments, the ink comprises the following raw materials in parts by weight: 24 parts of aqueous acrylic resin, 2.5 parts of diisobutyrate dioxide, 1.5 parts of nonpolar pigment and 2.2 parts of emulsifier.
On the other hand, the invention also provides a preparation method of the tipping paper ink, which comprises the following steps:
uniformly mixing diisobutyrate dioxide and an emulsifier, then adding a nonpolar pigment, and continuously uniformly mixing to obtain a first mixed solution;
and step two, heating the aqueous acrylic resin to 40-50 ℃, and adding the first mixed solution into the aqueous acrylic resin in a stirring state to obtain the tipping paper printing ink.
In some embodiments, the tipping paper printing ink obtained in the second step is kept in a stirring state at 40-50 ℃ before being used for printing, and is stored in a sealing way.
Compared with the prior art, the tipping paper printing ink and the preparation method thereof have the following beneficial effects:
the invention provides an ink for tipping paper, which is characterized in that a formula is optimized, a specific emulsifying system is adopted to form an ink formula capable of greatly reducing the pigment consumption, a nonpolar pigment is adopted to be used in the formula, the water-based acrylic emulsion is matched with a small amount of diisobutyrate, the diisobutyrate is environment-friendly and volatile, the diisobutyrate has a large surface tension, the emulsifying system formed by the diisobutyrate and the water-based acrylic emulsion is in a semi-stable state, particularly after printing, layering is easy to form, an intermediate interface layer is formed by layering under the action of an emulsifying agent, the nonpolar pigment is easy to be distributed on the interface layer, and the pigment can form a good spreading effect under the condition of extremely small consumption due to the large surface area and small thickness of the interface layer, so that the expected covering power is achieved.

| Coverage (%) | 96.8 | 73.2 | 81.9 |
The above data shows that when ethanol is used instead of diisobutyrate in the mixed solvent system, coverage rate is remarkably reduced, the stability of the intermediate layer of the mixed solvent is reduced due to the change of the solvent system, and pigment cannot be intensively dispersed in the intermediate layer, so that dispersibility is improved, pigment spreadability on a printing surface is reduced due to the dispersibility improvement, coverage rate is directly influenced, and when polyethylene glycol is used as an emulsifier, emulsification performance is improved, the intermediate layer of the mixed solvent system is more difficult to form, and the spreading effect of the pigment cannot meet the requirements of the invention when a drying process is unchanged.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the invention.
