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

[0048] According to the formula amount of Example 1 in Table 1, pure water, isopropanol, dispersant, wetting agent and defoamer were added to the dispersing kettle in turn at room temperature, and the pigment, The filler was stirred and mixed evenly at a speed of 150rpm, and then transferred to a horizontal sand mill (TBM-50, Taiyi (Shanghai) Industrial Co., Ltd.) for two passes of grinding, and the material was filtered to obtain a water-based color paste. Then add pure water, the above-mentioned water-based color paste, film-forming resin, thickener and foaming powder into the dispersion tank in turn, and then filter and discharge the material after stirring at a speed of 1200rpm for 1h to obtain the PVC furniture film water-based foaming ink .

Embodiment 2

[0060] According to the formula amount of Example 2 in Table 3, pure water, alcohol, dispersant, wetting agent and defoamer are added to the dispersing kettle successively at room temperature, and after stirring and mixing at a speed of 150rpm, pigments and fillers are added to Stir at a speed of 300rpm and mix evenly, then transfer to a horizontal sand mill (TBM-50, Taiyi (Shanghai) Industrial Co., Ltd.) to grind for 2 passes, filter and discharge to obtain a water-based color paste. Then add pure water, the above-mentioned water-based color paste, film-forming resin, thickener and foaming powder into the dispersion tank in sequence, stir at a speed of 1000rpm for 1.5h, and then filter the material to obtain the PVC furniture film water-based foam ink.

Abstract

PVC furniture film water-based foaming ink consists of the following raw materials in parts by weight: 8 to 30 parts of a titanium dioxide powder, 5 to 25 parts of fillers, 1 to 8 parts of a dispersing agent, 1 to 4 parts of a wetting agent, 0.06 to 0.2 part of a defoaming agent, 40 to 150 parts of film-forming resin, 5 to 12 parts of low molecule alcohol, 80 to 160 parts of pure water, 3 to 7 parts of a thickening agent and 3 to 6 parts of a foaming powder. The water-based foaming ink is high in storage stability, high in scratch resistance and high in pressure resistance, and solves the technical problems of 'high foaming and strong attachment' of the foaming coating in the industry.

Description

(1) Technical field [0001] The invention relates to a water-based ink and a preparation method thereof, in particular to a water-based foaming ink applicable 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, etc...
