Problems solved by technology

When the ink is printed and dried, a large amount of organic solvent is released, which is flammable and explosive, and has caused great damage and pollution to printing workers and the environment.
Not only that, after entering the home improvement market, furniture with PVC furniture film will still slowly release VOC, which will undoubtedly cause long-term damage to consumers' home health

Embodiment 1

[0056] According to the formula amount of Example 1 in Table 1, add pure water, isopropanol, dispersant, wetting agent and defoamer to the dispersion kettle in turn at room temperature, stir and mix evenly at a speed of 100rpm, and then add pigment, The filler was stirred and mixed evenly at a speed of 200rpm, and then transferred to a horizontal sand mill (TBM-50, Taiyi (Shanghai) Industrial Co., Ltd.) for grinding for 4 passes, and filtered to obtain water-based red pulp. Then add pure water, the above-mentioned water-based color paste, film-forming resin, leveling agent, isopropanol, cosolvent and defoamer into the dispersion tank in turn, and filter and discharge the material after stirring at a speed of 150rpm for 0.5h to obtain the obtained Water-based red ink for gravure printing of PVC furniture film as described above.

Embodiment 2

[0065] According to the formula amount of Example 2 in Table 3, pure water, isopropanol, dispersant, wetting agent and defoamer were added to the dispersing kettle in turn at room temperature, stirred and mixed evenly at a speed of 50rpm, and then added pigment, The filler was stirred and mixed evenly at a speed of 300rpm, and then transferred to a horizontal sand mill (TBM-50, Taiyi (Shanghai) Industrial Co., Ltd.) for grinding for 4 passes, and filtered to obtain water-based yellow paste. Then add pure water, the above-mentioned water-based color paste, film-forming resin, leveling agent, isopropanol, co-solvent and defoamer to the dispersion tank in sequence, stir at a speed of 150rpm for 1h and then filter the material to obtain the described Water-based yellow ink for gravure printing of PVC furniture film.

Abstract

PVC furniture film gravure printing water-based ink consists of the following raw materials in parts by weight: 4 to 18 parts of pigment, 0.2 to 3 parts of fillers, 1 to 7 parts of a dispersing agent, 0.8 to 3.2 parts of a wetting agent, 0.08 to 0.24 part of a defoaming agent, 18 to 50 parts of film-forming resin, 0.2 to 0.3 part of a leveling agent, 8 to 30 parts of low molecule alcohol, 1 to 2 parts of a cosolvent and 10.78 to 43.2 parts of pure water. The bonding strength of the water-based ink on a PVC furniture film and a wear-resistant sheet can compare favorably with the bonding level of oily ink, and the transfer resistance on a plasticizer exceeds the level of the oily ink; furthermore, the printing effect of the water-based ink is more excellent that that of the oily ink in the market, and the leveling effect and the glossiness are more excellent than those of an oily system.

Description

(1) Technical field [0001] The invention relates to a water-based ink and a preparation method thereof, in particular to a water-based ink which can be applied to PVC (polyvinyl chloride) furniture film gravure printing and a preparation method thereof. (2) Background technology [0002] With the rapid development of the industrial economy, the contradictions between the world's population, resources and the environment have further increased, the discharge of environmental pollutants and the destruction of natural ecology have continued to increase, and the pressure on global environmental protection has become increasingly serious. At present, the printing of domestic PVC plastic decorative films (mainly PVC floor films and PVC furniture films) is still dominated by solvent-based inks. Solvent-based inks contain a large amount (generally accounting for more than 60% of the ink composition) volatile organic solvents (VOC), such as Toluene, xylene, ethyl acetate, butanone, e...
