Embodiment 1-3
[0028] Adopt the components and proportions shown in Table 1 respectively
[0029] The preparation methods are as follows: except the adhesion agent, antifoaming agent, drying regulator and 9% deionized water, the rest of the resin emulsion and solvent are first stirred evenly, and then the pigment and matte material are added and the stirring is continued. Uniform; the mixed components are then ground by a grinder, and the grinding is stopped after the fineness reaches # The cup is 20-28 seconds / 25°C, the pH value is between 8.0-9.0, and finally filtered and packaged.
[0030] Printing requirements: printing speed: 150-240 m / min;
[0031] Gravure depth: 30-45 microns;
[0032] Drying temperature: 45-55°C;
[0033] Printing viscosity: 11-15 seconds / 25°C / thin-walled 3# Zahn cup.
[0034] Components and ratios thereof of the printing ink of table 1 embodiment 1-3
[0035]
[0036] Among them, the "self-modifying resin emulsion" in Table 1 is obtained by emulsifying and mi...
