Embodiment 1
[0047] The production method of red water-based ink printing film:
[0048] The first step: the preparation of water-based ink;
[0049] 1) Mix 50 parts of water with 2 parts of ammonia water to make a mixture of water and ammonia water for later use;
[0050] 2) Put 15 parts of red pigment, 30 parts of binder, 2 parts of additives, and 1 part of anti-wear agent into the dispersion mixing tank for dispersion and stirring; the stirring time is 40 minutes, and the stirring speed is 800r / min;
[0051] 3) Pour out the stirred material, add the water and ammonia water mixture, and adjust the pH value to 9;
[0052] 4) Add water to the material and adjust the fluidity to 25s / 3#cup / 25°C.
[0053] The second step: Corona treatment is carried out on the film before printing water-based ink on the film; use a film corona treatment machine to perform corona treatment on the film to be printed, so that the surface tension of the film reaches 50 dyn / cm;
[0054] The third step: printing...

Abstract
The invention relates to the field of printing films, in particular to a waterborne ink printing film and a manufacture method thereof. According to the waterborne ink, water-base polyurethane latex is utilized as a waterborne ink connection material to enhance the adhesive force between the ink and the film. Thus, the waterborne ink is stronger in stability, the waterborne ink has stronger mobility resistance, the film layer is suitable for printing waterborne ink by means of designing a formula of the film layer, and the compatibility between the waterborne ink and the film is improved. Due to the fact that no plasticizer is added into the film layer raw material, the problem of plasticizerprecipitation is solved. By means of adding EEA particles into the formula, the toughness and the thermal stability of the film are effectively improved. Due to the fact that no plastic lubricant is added into the formula, the problem that the plastic lubricant and a low-molecule material dissolve out of the surface of the film to affect the stability of the waterborne ink on the film is solved.
Description
technical field [0001] The invention relates to the field of printing films, in particular to a water-based ink printing film and a manufacturing method thereof. Background technique [0002] The existing printing inks in my country are petroleum distillate, benzene and its derivatives or ketoneorganic solvent inks. During the production process, they have caused harm to the health of workers. If they are used as printing inks for food packaging, small The migration and penetration of molecular organics will have an impact on consumer health. [0003] Water-based ink, referred to as water-based ink for short, is composed of water-soluble or water-dispersible polymer resin as a binder, organic pigments, solvent water and related additives. The main difference between water-based inks and oil-based inks is that solvent-based inks use organic solvents as solvents, while water-based inks use water (45% to 50%) as solvents. Therefore, water-based inks have the advantages of extr...
