Embodiment 1

[0025] The specific raw materials are weighed according to Table 1, and the preparation steps are as follows:

[0026] (1) Mix half the amount of water and ethanol with styrene-acrylic resin and nano-TiO 2 / SiO 2 Compound modified acrylic resin and maleic acid modified rosin resin, and stirred at 60°C for 40min at 800r / min to obtain mixture A;

[0027] (2) mixing the cationic modified mica, Tween 80, sodium lauryl sulfate and the remaining formula amounts of water and ethanol, and stirring at 65° C. at 400 r / min for 15 min to obtain mixture B;

[0028] (3) Add mixture B to mixture A, and stir at 1100 r / min at 45°C for 1.5 h to obtain mixture C;

[0029] (4) Use a sander to grind the mixture C at 1200 r / min for 40 minutes, that is, it is obtained.

Embodiment 2

[0031] (1) Mix half the amount of water and ethanol with styrene-acrylic resin and nano-TiO 2 / SiO 2 Compound modified acrylic resin and maleic acid modified rosin resin, stirred at 70°C for 30min at 1000r / min to obtain mixture A;

[0032] (2) mixing the cationic modified mica, Tween 80, sodium lauryl sulfate and the remaining formula amounts of water and ethanol, and stirring at 75° C. at 600 r / min for 10 min to obtain mixture B;

[0033] (3) Add mixture B to mixture A, and stir at 1200 r / min at 55°C for 1 h to obtain mixture C;

[0034] (4) Use a sander to grind the mixture C at 300 r / min for 30 minutes, and then obtain.

Embodiment 3

[0036] (1) Mix half the amount of water and ethanol with styrene-acrylic resin and nano-TiO 2 / SiO 2 Compound modified acrylic resin and maleic acid modified rosin resin, stirred at 70°C for 40min at 1000r / min to obtain mixture A;

[0037] (2) mixing the cationic modified mica, Tween 80, sodium lauryl sulfate and the remaining formula amounts of water and ethanol, and stirring at 600r / min for 15min at 75°C to obtain mixture B;

[0038] (3) Add mixture B to mixture A, and stir at 1200 r / min at 55°C for 1.5 h to obtain mixture C;

[0039] (4) Use a sander to grind the mixture C at 1300r / min for 40min, that is, it is obtained.

Abstract

The invention provides ultra-thin special water-based ink for gravure printing. The water-based ink is prepared from the following raw materials in parts by weight: 40 to 50 parts of styrene-acrylic resin, 30 to 40 parts of nano TiO2 / SiO2 composite modified acrylic resin, 5 to 8 parts of cation modified mica, 10 to 20 parts of maleic acid modified rosin resin, 4 to 6 parts of Tween 80, 10 to 20 parts of lauryl sodium sulfate, 70 to 90 parts of 70 percent ethanol and 80 to 100 parts of water. The cationic modified mica is added, and the cationic modified mica sheet is rich in polar groups such as hydroxyl and amido, and cooperates with the nano TiO2 / SiO2 composite modified acrylic resin to improve the curling condition of the tipping paper. According to the invention, by adding the cation modified mica, the cation modified mica sheet is rich in polar groups such as hydroxyl and amido, can realize uniform distribution and uniform orientation in the acrylic resin, and cooperates with the nano TiO2 / SiO2 composite modified acrylic resin to improve the curling condition of the tipping paper.

Description

technical field [0001] The invention relates to the technical field of ink, in particular to a water-based ink for ultra-thin special gravure printing and a preparation method thereof. Background technique [0002] In the production of cigarette pack printing, paper curl can cause serious problems in post-press processing and use. For example, after the printed sheet is curled, the positioning error of the subsequent cross-cutting, hot stamping, and die-cutting processing will increase, and the paper will not run smoothly, which will cause the machine to jam and stop, which will seriously affect the efficiency and quality of the subsequent processing. The printed sheet is processed into a single finished product The curling after the cigarette pack will bring difficulties to the paper feeding of the folder gluer and automatic packaging machine. [0003] In the prior art, the Chinese Patent Publication No. CN201310089793.4 discloses a special water-based ink for printing cig...
